[00:00:12] <MrHindsight> pay cash
[00:00:17] <MrHindsight> vs tied sale to CC
[00:00:26] <hazzy-lab> I try to do all my shopping at publix, prices are a little higher, but service is top notch and no funny business
[00:00:39] <MrHindsight> or join a card swap club
[00:01:10] <hazzy-lab> I only use cash except for web purchases, mainly because I am so hard on cards they only last a few months, lol
[00:01:34] <hazzy-lab> The new chip cards are very fragile
[00:01:44] <MrHindsight> yeah I just cracked one last week
[00:02:04] <MrHindsight> not a chipped card, cracked right in the middel if the strip
[00:03:54] <MrHindsight> over the years I noticed maybe a 5-9% savings when using a store customer card
[00:04:17] <hazzy-lab> When I worked at the school I had to have an card to get into the labs the guys at the ID center started making me pay for new cards because I went thru so many!
[00:05:22] <MrHindsight> hey, make a decent card
[00:05:31] <MrHindsight> it's one thing if you lost them
[00:05:47] <MrHindsight> but cracking while in your wallet is pretty poor
[00:06:07] <hazzy-lab> Never lost one, but they would ether crack or the strip would rust thru
[00:06:14] <MrHindsight> spend $0.05 per lb of plastic
[00:06:28] <MrHindsight> more than the cheap stuff
[00:06:50] <hazzy-lab> It can't be that hard to make a good card
[00:07:08] <MrHindsight> the markup on them is pretty good
[00:07:13] <hazzy-lab> But most people just sit on a couch all day, so the cheap ones last :D
[00:07:17] <MrHindsight> I knew a vendor based in India
[00:07:25] <MrHindsight> they made millions making cards
[00:07:52] <`Wolf> https://www.ebay.com this project is starting to seem like overkill… think this is any good?
[00:08:21] <MrHindsight> about the same price as a manula one
[00:08:25] <MrHindsight> manual even
[00:09:03] <hazzy-lab> I bet, they must cost a good bit, even the basic ones, as hotels think its worth charging for stolen cards :D
[00:09:05] <`Wolf> then, just need ptfe tube?
[00:09:32] <MrHindsight> `Wolf: does it have external trigger inputs?
[00:09:56] <hazzy-lab> `Wolf: Thats cheap(until the tariffs hit)! Looks decent too ..
[00:10:15] <`Wolf> I don’t see external trigger
[00:10:18] <MrHindsight> I tie them back to the controller
[00:10:28] <MrHindsight> only runs when the machine is moving
[00:10:29] <`Wolf> but I doubt it would be hard to make it
[00:10:43] <MrHindsight> vs just by time
[00:11:27] <`Wolf> have it turn on w/ enable or something
[00:11:47] flyback is now known as fishhead
[00:11:55] <`Wolf> or gcode trigger?
[00:11:56] <hazzy-lab> Does anybody use the HAL lube pin?
[00:12:11] <hazzy-lab> I don't know what it does ..

[00:13:19] <hazzy-lab> heh: http://wiki.linuxcnc.org
[00:13:43] <`Wolf> lol I might just get 2 of those pumps then, put one on the knee mill at some point

[00:15:12] <MrHindsight> https://www.ebay.com
[00:15:56] <pink_vampire> MrHindsight: what is that?
[00:16:09] <MrHindsight> same place just price with shipping included
[00:16:41] <MrHindsight> they have multiple listings all the same shipped price :)
[00:17:03] <`Wolf> that one is $1 more after + shipping and 1.8 vs 2lt
[00:17:44] <MrHindsight> I've seen some with multiple listing maybe 1 cent different in price
[00:18:06] <MrHindsight> makes searches more difficult at times
[00:18:46] <`Wolf> its for the people who don’t use the price+shipping sort feature
[00:21:02] <`Wolf> for the rest of the thing, M5 thread 4mm push fittings and 4mm OD PTFE tube is whats needed right?
[00:21:16] <`Wolf> not counting a manifold block
[00:23:51] -!- Radicarianubis has quit [Ping timeout: 240 seconds]
[00:26:23] <`Wolf> I want to at least plumb in some of it before I close up the X/Y
[00:26:48] <hazzy-lab> `Wolf: that sounds right
[00:27:53] <`Wolf> hmm, actually looks like all but 1 of the Y will be accessible on this thing
[00:27:55] <hazzy-lab> bijur makes "special" lube pump tubing (it have very think walls), but I am sure PTFE would be fine, the pressure is not very high
[00:28:44] <`Wolf> kinda what I was thinking
[00:28:58] <`Wolf> way oil not grease injection
[00:29:40] <hazzy-lab> right
[00:29:58] <hazzy-lab> You probably wont even need metering values for an X2
[00:30:11] <hazzy-lab> just make sure it gets plenty of oil
[00:30:33] <`Wolf> true lol
[00:30:55] <`Wolf> … damn X ball screw needs a pocket milled for the oil port
[00:31:29] <hazzy-lab> those little mills have sooo little clearance :(
[00:32:09] <`Wolf> yeah, and I’m using “12”mm ball screws
[00:32:21] <`Wolf> most everyone says they won’t fit on this thing
[00:32:28] <hazzy-lab> yeah, that must be tight!
[00:32:37] <hazzy-lab> 8mm is not easy lol
[00:33:25] <`Wolf> https://i.imgur.com plenty of room
[00:33:53] <`Wolf> Y axis clears the original lead screw nut mount by 1mm
[00:34:00] <hazzy-lab> It didn't even have the butcher the ballnut that bad, nice!
[00:34:30] <`Wolf> yeah, just needed a slot 1/2 way through the casting lol
[00:35:23] -!- gambakufu has joined #linuxcnc
[00:35:23] <hazzy-lab> heh, so there is about 1/16" left?
[00:35:25] <hazzy-lab> :)
[00:36:58] <hazzy-lab> Those little mills are surprisingly capable for how light they are, I am always impressed what people do with them
[00:38:01] <`Wolf> Y https://i.imgur.com and X https://i.imgur.com
[00:38:53] <hazzy-lab> very nice solution for X!
[00:39:12] <`Wolf> https://i.imgur.com an the Y axis the motor is going to be rear mounted
[00:40:57] <`Wolf> lol https://i.imgur.com
[00:40:59] <hazzy-lab> YES! I always wanted to see somebody do that!
[00:41:04] <`Wolf> that one is good for a laugh
[00:41:15] -!- fragalot has joined #linuxcnc
[00:41:41] <hazzy-lab> Thats good! a smaller machine making a bigger one
[00:41:53] <`Wolf> funny part is I got this table to upgrade the X1
[00:42:10] <fragalot> hi
[00:42:38] <`Wolf> looked at the adapter plate it came with and ended up calling little machine shop to find out if the X2 solid column would fit on it
[00:44:09] <hazzy-lab> Closest I have come to that, I can't compete :D : https://i.imgur.com
[00:45:00] <`Wolf> =)
[00:45:33] <`Wolf> https://i.imgur.com some people thought this was a solid slab
[00:45:34] <hazzy-lab> So you are putting the X2 column on the X1?
[00:46:19] <`Wolf> the extended X/Y kit for the X1 LMS sells is actually a X2 table from one of the models they don’t sell in the US
[00:46:20] <hazzy-lab> Man, am I spoiled
[00:47:01] <`Wolf> I milled this thing with the X1 https://i.imgur.com lol
[00:47:06] <hazzy-lab> Ah, I always wondered about that, so they are not custom made
[00:47:46] <hazzy-lab> Thats nice work! I would not have the patience
[00:48:05] <`Wolf> http://www.siegind.com
[00:48:28] <`Wolf> I cheated, I used two of the screw holes to line up the 2nd op
[00:49:06] <`Wolf> X2P mill table and SX1P
[00:49:58] <hazzy-lab> I did not realize they made that many variations
[00:50:25] <`Wolf> yeah, thats cause all we see is the X2 with the junk tilt column lol
[00:50:29] <`Wolf> and the X1
[00:52:51] <MrHindsight> https://postimg.cc what to do with?
[00:53:41] <`Wolf> https://littlemachineshop.com + the extended Y kit, and parts from the LMS Hightorque mill
[00:53:44] <skunkworks> yumm what is it from?
[00:53:55] <hazzy-lab> MrHindsight: That makes me drool
[00:54:02] -!- Radicarianubis has joined #linuxcnc
[00:54:05] <`Wolf> I say use it to make a 3d printer
[00:54:07] <MrHindsight> he brand spanking new
[00:54:08] <`Wolf> =P
[00:54:16] <MrHindsight> he/heh
[00:55:42] <MrHindsight> was probably for the X or Y on a EDM
[00:56:42] <`Wolf> make it 520mm and send it here, I cut my Z screw too short for my X2 lol
[00:58:21] <`Wolf> hmm, I’m not sure how to get a oil line in to this X axis nut
[00:59:07] <MrHindsight> skunkworks: how are things up there?
[01:00:01] <`Wolf> any crazy ideas? M5 screw is the oil port https://i.imgur.com
[01:01:32] <`Wolf> and I can’t flip it over because of the table casting
[01:01:40] <MrHindsight> flexible oil line
[01:02:32] <`Wolf> nut needs to have the port pointing in to the slot to work
[01:03:01] <`Wolf> push fitting isn’t going to fit in there
[01:03:14] -!- c-log has quit [Ping timeout: 260 seconds]
[01:03:28] <MrHindsight> how much clearance is there?
[01:03:38] <MrHindsight> from the nut to the slot?
[01:03:54] <MrHindsight> 5-6mm?
[01:03:55] <`Wolf> https://i.imgur.com
[01:03:59] <`Wolf> almost none
[01:04:38] -!- fragalot has quit [Read error: Connection reset by peer]
[01:04:45] -!- c-log has joined #linuxcnc
[01:04:46] <`Wolf> port sits inside that slot
[01:05:40] -!- slipalong has joined #linuxcnc
[01:06:22] <MrHindsight> well now is a fine time to think of this! :)
[01:06:49] <`Wolf> lol
[01:07:33] <`Wolf> better now then after I have the whole thing built then go, hey I should have put a oil system on this
[01:07:34] <MrHindsight> have it drip on the screw, add a wiper if it flings off
[01:07:41] <MrHindsight> it's oil not grease
[01:07:55] <`Wolf> I was thinking make a banjo fitting
[01:08:53] <`Wolf> I can open up the slot some
[01:10:02] -!- Radicarianubis has quit [Remote host closed the connection]
[01:10:08] <`Wolf> I could have some real fun and try to find some 4mm copper tube lol

[01:12:33] <MrHindsight> https://www.mettleair.com
[01:14:29] <`Wolf> Link: http://a.co even smaller
[01:14:52] <`Wolf> oh wait, thats 6mm OD tube fitting
[01:15:46] <MrHindsight> do they have drawings somewhere?
[01:16:18] <`Wolf> I was thinking more like a 4.5mm thick washer w/ 4mm OD tube brazed in, then just drill a screw and add some teflon washers
[01:18:04] <`Wolf> or just use orings…
[01:21:00] <MrHindsight> can you drill a passage in a different location with more clearance?
[01:21:21] <`Wolf> I think that nut is hardened
[01:21:28] <MrHindsight> figures
[01:24:30] <`Wolf> https://i.imgur.com plus that location with more clearance
[01:24:57] <`Wolf> that would be on someother machine lol
[01:26:27] <`Wolf> this is why no one builds X2 mills with 10mm ballscrews

[02:32:30] <`Wolf> ships within 6-10 days,,, wtf lol
[02:36:04] <MrHindsight> https://postimg.cc piston leaks
[02:36:39] <`Wolf> not hard to repack, but a total pain in the ass to get out
[02:36:42] <MrHindsight> do you think that the collar screws off for access to the o-rings?
[02:37:11] <`Wolf> should
[02:37:26] <`Wolf> and will have a stack of glands under it
[02:37:39] <MrHindsight> take top crap off, unscrew top...
[02:38:08] <`Wolf> actually, might be just oring and wiper, forgot those aren’t power down
[02:38:15] <MrHindsight> it leaves a puddle few oZ when it's used a bunch after parking
[02:38:25] <MrHindsight> yeah just gravity down
[02:38:48] <MrHindsight> I have plenty of fluid
[02:38:48] <`Wolf> I need to re pack the ones on my truck, 4000psi in/out
[02:38:54] <MrHindsight> ah yeah
[02:39:14] <`Wolf> I had one totally blow out, that was a mess
[02:39:24] <MrHindsight> looks like I can lift the forks 12" and then support it...
[02:39:41] <MrHindsight> the remove all the attachments to the top
[02:39:43] <`Wolf> 5 tons of road salt on the truck when it popped
[02:41:03] <MrHindsight> I can probably make a tool to unscrew it if requires persuasion
[02:41:28] <`Wolf> that was almost as bad as when the dump gate lock popped open, dumped full 5 tons of salt in the middle of the road lol
[02:41:40] <MrHindsight> oh man
[02:41:50] <`Wolf> should have pin spanner holes or we just use a big pipe wrench on them
[02:42:06] <MrHindsight> this is 10" in dia
[02:42:27] <`Wolf> really big pipe wrench =)
[02:42:37] <`Wolf> I think we have a 48”
[02:42:54] <MrHindsight> 7" OD
[02:42:57] <MrHindsight> just measured
[02:43:20] <MrHindsight> it has spanner notches
[02:43:41] <MrHindsight> middle of lower pic
[02:44:03] <MrHindsight> 3/4" wide 1/2" deep
[02:44:44] <`Wolf> that shouldn’t be too bad
[02:45:13] <MrHindsight> http://www.shars.com for a big version of this
[02:45:50] <`Wolf> yup
[02:46:09] <`Wolf> usually a U with two blocks welded on I thin
[02:46:11] <`Wolf> k
[02:46:17] <MrHindsight> https://www.amazon.com
[02:46:24] <MrHindsight> but more bigger
[02:46:42] <`Wolf> I have a set of those, just not that big
[02:47:18] <MrHindsight> I can make one
[02:47:52] <MrHindsight> cut some plate and weld or bolt on an arm for persuasion
[02:47:54] <`Wolf> https://i.imgur.com I think the cylinders are only 4-5” on this thing
[02:48:34] -!- slipalong has joined #linuxcnc
[02:48:48] <MrHindsight> I'd like to find a long reach fork lift like ...
[02:49:06] <`Wolf> I really want a tele handler
[02:49:37] <MrHindsight> https://www.youtube.com
[02:49:56] <MrHindsight> 20k-25k lbs should be enough
[02:50:04] <`Wolf> yup, telehandler
[02:50:20] <`Wolf> they make them with quick attach plates that the skid loaders use
[02:50:24] <MrHindsight> i rarely have anything I need to move heavier than that
[02:50:31] <MrHindsight> famous last words
[02:51:47] <`Wolf> I ran one just like in that vid when I worked construction, great machines
[02:52:00] <`Wolf> moving K barriers around with it
[02:52:20] <MrHindsight> I can park a semi in here but I can't get my 10K lb forklift down the hall to the doc
[02:52:31] <MrHindsight> they made the ahlls to narrow and the doors to small
[02:52:43] <`Wolf> doh
[02:52:43] <MrHindsight> ahlls/halls
[02:53:22] <MrHindsight> I can back in a flatbed or full trailer but if it's over 10K lbs I can't unload it
[02:54:05] <`Wolf> crew building a house across from my parents house got one of those lulls “stuck”, actually turned out that none of them knew how to run the thing
[02:54:44] <MrHindsight> they made the doors for 6 ft wide by 6 ft high pallets on the dock side
[02:55:12] <MrHindsight> 12 ft x 12ft on the drive in bay
[02:55:16] <`Wolf> that wasn’t smart
[02:55:33] <MrHindsight> cheapskate owners/builders
[02:55:33] <`Wolf> most forklifts are 7’
[02:56:00] <MrHindsight> I can get it through the door but can't make the turn down the hallway
[02:56:05] <`Wolf> and thats level, not tilted… don’t ask how I know this
[02:56:12] <MrHindsight> need 6" more inches
[02:56:46] <`Wolf> I bet the forklift will move the wall
[02:57:09] <MrHindsight> just measured 7' 10" clear height
[02:57:41] <MrHindsight> it has an extra ton on the back that is removable
[02:57:56] <MrHindsight> adds another ft to the length
[03:00:10] <MrHindsight> some idiot before we were here pulled out without raising the doors enough
[03:00:39] <MrHindsight> roll up doors are all bowed out near the bottom
[03:01:04] <`Wolf> odd, I have the counterweight off my one truck (because the motor is out) but I don’t think I have seen a extra weight on one

[03:03:16] <MrHindsight> rear weight ^^
[03:04:19] <`Wolf> I dunno about that being a aux weight
[03:04:30] <MrHindsight> it unbolts
[03:04:40] <Deejay> forklift?
[03:04:43] <`Wolf> yeah, need to take it off to get to the motor usually
[03:04:45] <Deejay> ah
[03:04:50] <MrHindsight> has fins for the the radiator
[03:05:27] <MrHindsight> 1 to 1-1/4" thread from the size of the head
[03:06:00] <MrHindsight> the top of the engine has a cover that comes off
[03:06:49] <MrHindsight> just sheet metal on top
[03:06:52] <`Wolf> yeah, to pull the motor you need to take the weight off
[03:07:18] <`Wolf> even then its a pain in the ass lol
[03:07:30] <MrHindsight> it's a 6-cylinder Ford or Chrysler
[03:07:34] <MrHindsight> not planning
[03:07:56] <`Wolf> not much choice when the waterpump goes up
[03:08:22] <`Wolf> which oddly mine wasn’t over heating, the propane reg would freeze and shut the thing off

[03:12:19] <MrHindsight> we looked at space that had a 25 ton gantry crane
[03:12:36] <MrHindsight> ran probably 50ft through the shop
[03:12:43] <MrHindsight> 20 ft wide
[03:12:52] <`Wolf> if I ever build a new shop I’m putting a gantry crane in it

[03:26:04] <MrHindsight> slots on the side
[03:26:14] <MrHindsight> don't see any hoses
[03:26:27] <`Wolf> looks like a aux heater, like you would stick in a skid loader or backhoe
[03:26:42] <`Wolf> can see the hoses in one of the side pics
[03:26:42] <MrHindsight> maybe
[03:26:52] <MrHindsight> gets pretty cold up here yonder
[03:26:59] <`Wolf> I have the same heater on my shelf
[03:27:09] <`Wolf> came in a backhoe I had for a while

[03:28:32] <MrHindsight> $72K for a 5 ton https://chicago.craigslist.org
[03:29:19] <`Wolf> yeah, those things are crazy expensive
[03:29:46] <MrHindsight> I have a tiltbed truck service near me rated at 20k lbs
[03:30:20] <MrHindsight> he can back in and slide a machine off or on
[03:30:29] <`Wolf> thats handy
[03:30:40] <MrHindsight> $125/hr
[03:30:54] <`Wolf> I thought about making a flatbed for my truck to move stuff like that with
[03:31:12] -!- asdfasd has joined #linuxcnc
[03:31:17] <MrHindsight> I have 24 ft ceilings
[03:31:20] <`Wolf> but I’m maxed at just under 5ton by GVW
[03:32:33] <MrHindsight> need a better space, there is no insulation between units, just 4 layers of sheetrock
[03:32:54] <MrHindsight> 2 on each side
[03:32:59] <`Wolf> ugh
[03:33:32] <MrHindsight> our last space had 8" concrete walls on all asides
[03:34:18] <MrHindsight> we had a tornado pas nearby and the building was shaking, I was milling at the time and though it was chatter
[03:34:26] <`Wolf> lol
[03:34:44] <`Wolf> I just want to drop a 40’x60’ shop in my back yard
[03:34:47] <MrHindsight> I opened the door to se what was up and the rain was green and blowing sideways
[03:34:59] <MrHindsight> i was instantly soaked
[03:35:23] <`Wolf> we don’t get those too often out here
[03:35:43] <`Wolf> I like 10yrs ago, missed my yard by 100 feet
[03:35:47] <`Wolf> i/one
[03:40:34] <MrHindsight> https://postimg.cc funnel just forming overhead
[03:43:36] <`Wolf> never a good sign lol
[03:45:24] <MrHindsight> https://postimg.cc you can clearly see the front
[03:45:53] <`Wolf> oh yeah
[03:46:53] <MrHindsight> wee seem to get one really big storm a month in the summer now
[03:47:10] <MrHindsight> green skies, near black clouds
[03:47:31] <MrHindsight> trees down
[03:49:11] <`Wolf> hmm, what in the quill would cause crunchy noise + vibes, but only at 600 rpm, machine is dead smooth at 1200
[03:51:02] <MrHindsight> lucky resonance
[03:51:09] <`Wolf> belt drive machine w/ 2 speed motor
[03:51:25] <MrHindsight> crinchy is never good
[03:52:17] <`Wolf> part of me wants to check out the head, other part doesn’t want to pull the motor off the top
[03:52:40] <MrHindsight> has to be bearings
[03:52:50] <MrHindsight> unless something else got loose in there
[03:53:00] <MrHindsight> small nuts or screw or chips
[03:53:26] <`Wolf> yeah, but motor, quill pulley, or spindle lol
[03:54:16] <`Wolf> doesn’t help that the 1hp motor is the size of a 2gallon bucket
[03:56:22] <`Wolf> I think it needs a nice newer brushless w/ vfd
[03:59:58] <MrHindsight> would a stethoscope help?
[04:00:03] <`Wolf> I guess I can pull the drive pulley off and clean it, I want to check it anyways to see if I can add the optional spindle brake that is missing
[04:00:21] <`Wolf> it rattles enough that I can see the DRO shake
[04:00:48] <`Wolf> in high speed I’ll forget its running
[04:03:47] <MrHindsight> the spindle on my Matsuura went, makes the occasional crunch sound, still runs at 6K but leakes spindle oil now and the tool changer requires some persuasion
[04:04:47] <MrHindsight> usually a screw driver driven by a dead blow between holder and chuck
[04:05:29] <MrHindsight> I have drop the head and upgrade this to something faster

[05:56:17] <Loetmichel_> ... with a battery drill in second gear ;)
[05:56:44] <Wolf_> ha, no thanks
[05:56:44] <XXCoder> lot bah thats nothing
[05:57:10] <XXCoder> 4 holes each part, already anodized, its very thin drill, and almost fully inch deep hole
[05:57:14] <XXCoder> then tapped
[05:57:22] -!- micges has joined #linuxcnc
[05:57:31] <XXCoder> I have to hand-clean all tapped holes because derbis dont get out
[05:57:39] <pink_vampire> link for the amazing tap?
[05:57:43] <Loetmichel_> where do you get an M2 tap that has 25mm useable length?
[05:57:53] <XXCoder> special order
[05:57:59] <XXCoder> its expensive tool
[05:58:23] * Loetmichel_ had to grind down the shaft of the m2 tap i have here to get it into the 8mm blind hole already...
[05:58:38] <XXCoder> basically part final form has 2 different anodized colors, so basically we mill it complete except one area and 4 tapped holes, send it off to be anodided
[05:58:48] <XXCoder> then we mill the pocket area, add 4 holes
[05:59:21] <XXCoder> also, cleaning is insane consider runtime is just over 2 minutes and I gonna do 100% cleanup :(
[05:59:32] <XXCoder> sometimes I even have to re-tap holes
[05:59:46] <XXCoder> and its 500 parts job lol
[06:00:55] <XXCoder> also, its not m2
[06:01:04] <XXCoder> lets see if I could remember drill size
[06:01:34] <XXCoder> I think its smaller drill
[06:01:43] <XXCoder> imperial here lol
[06:05:23] <Loetmichel_> ... was "fun" to cut with that modified tap (lower, the upper one is original, max 6mm deep) -> http://www.cyrom.org
[06:06:06] <pink_vampire> look very nice
[06:06:29] <XXCoder> why was it needed?
[06:07:09] <Loetmichel_> needen 8mm deep threads :-)

[06:27:27] <Tom_L> works like a charm
[06:38:05] <Loetmichel_> yeah. problem is that the thinnest part of that tap is a mere 1,3mm now, and 8mm deep puts quite a bit of torque onto the tap, even if you clean out every few turns and relube.
[06:38:38] <Loetmichel_> i made it thru 12 holes without a single break, but i sweated it profusely while doing so ;)

I ordered a new parallel port cable when i ordered a new breakout board and other bit to replace the parts i thought did not work. The cable was the last thing to turn up today, So i thought what the hell ill fit it befor i do the video then moved everything in to position to do the video. I Turned on the computer and the system and CLUNK, i turned around

[12:16:31] <Joe_Hildreth> Hello all. On this page: http://linuxcnc.org there is a table showing the three modes the PP can be run in.
[12:16:33] <jesseg> I was thinking of using chainsaw bar oil on my little engraver spindle bearings, since it won't all run out, but I'm not sure if that's so thick the balls would skate
[12:17:25] <Joe_Hildreth> In the first column, the "in" column pin 14 is listed as an input, I think this should read as an output. Am I correct here?
[12:19:07] <gloops> good to hear amxen
[12:19:28] <Joe_Hildreth> Hi gloops
[12:19:33] <gloops> howdy
[12:20:06] <jesseg> Joe_Hildreth, I'm checking into it
[12:20:13] <Joe_Hildreth> Thank you.
[12:20:30] <amxen> gloops its workin mate
[12:20:52] <gloops> you did very well there amxen
[12:21:03] <amxen> it was the bloody parrallel port cable
[12:21:17] <gloops> others have taken...much longer lol
[12:21:29] <gloops> yes i thought it was the parport side
[12:21:57] <amxen> well it was the last thing that came today and i thought what the hell
[12:22:15] <jesseg> Joe_Hildreth, I'm not sure. Some other sources list pin 14 (the Autofeed) pin as being bidirectional while others indicate it to be just an output. It may be an open collector input/output pin in some printer port modes
[12:22:23] <gloops> alls well that ends well, the machine works and youre a bit wiser
[12:22:44] <amxen> change the cable now the output side is changing when i jog . from 5.1 to 3.4v
[12:23:12] <gloops> the rest is easy
[12:25:48] <amxen> yes man now i know it works . just got the motor chuning to do now as they jam a little
[12:26:21] <gloops> what motors are on it?
[12:26:31] <Joe_Hildreth> jesseg, pin 14 is part of the control group (pins 1, 14, 16 and 17) The diagrams that I have list these as bidirectional. I am going on the assumption that if the other three pins are output that it would follow that pin 14 would be also.
[12:26:47] -!- P1ersson has quit [Ping timeout: 244 seconds]
[12:27:53] <jesseg> Joe_Hildreth, That may not be a solid assumption considering the amount of evolution the parport has had
[12:28:56] <Joe_Hildreth> jesseg, you may be correct. I think I will set a port as input and see what stepconf lists it as.
[12:29:47] <jesseg> hrm, this page says not to oil spindle bearings on an engraver: http://www.engravingsys.com
[12:29:55] <Joe_Hildreth> I am working on another CNC for the home hobbyist video and am covering the parallel port some more. I just want to make sure I am giving good information, and this just seemed to stick out at me.
[12:31:52] <Joe_Hildreth> jesseg, from reading the chart, it looks like in out mode that the control pins are all set to outputs, in x mode it looks like they are all set to inputs, while in mode filps that bidirectional data pins. You see my confusion here, yes?
[12:32:09] <amxen> iv got 2 nema 425s and a 570
[12:32:23] <amxen> nema23
[12:32:47] <gloops> are these on 5mm pitch ballscrews - probably 36v power

[12:34:21] <amxen> the 425 are on 36v and the 570 is on 48v

[13:06:24] <gloops> jesseg the spindle bearings are sealed, theyve got lubrication
[13:13:36] -!- FinboySlick has joined #linuxcnc
[13:17:22] <gregcnc> jesseg what kind of spindle is it?
[13:24:33] <jesseg> gregcnc, hrm.. It's on an old Newigg/Newing Hall NH100 cnc engraver. It's got a little 120VDC brush perm mag motor with a 2" pulley which drives a 0.675" pulley with a round rubber belt on the spindle.
[13:25:02] <jesseg> There's two little bearings and the "quill" goes up and down with a little air ram
[13:27:32] <gregcnc> and hat does the mfg says about lubrication?
[13:28:20] <jesseg> Not sure... this thing is so bloody old I haven't been able to find much info on it but will try again
[13:28:30] <jesseg> Is it common for engraver ball bearings to be run dry?
[13:28:48] <gregcnc> you mean grease?
[13:28:51] <jesseg> yes
[13:29:00] <gregcnc> if designed as such
[13:29:06] <jesseg> as in no grease, no oil, and no air.
[13:29:39] <jesseg> I mean I'm aware of mag lev bearings, air bearings, oil bearings, but these are just plain ball bearings.
[13:30:07] <gregcnc> the MFG is still around, they couldn't help?
[13:30:29] <gregcnc> bearing are run completely dry on very rare occasions
[13:30:40] <jesseg> at 10k rpm?
[13:31:11] <gregcnc> there should not be any need to guess at how these spindle should be librucated?
[13:31:46] <gregcnc> http://www.newing-hall.com
[13:36:53] <MrHindsight> diverdude: easily with a galvohead
[13:38:41] <jesseg> lol thanks gregcnc much appreciated it? I guess I'll shot them a comment. I will be very pleasantly surprised if anyone working there in CS even remembers the NH 100 much less has any info for me, but it's sure worth a try :D
[13:39:00] <jesseg> that is to say I did shoot them a comment.
[13:39:00] <gregcnc> I would go there first
[13:39:20] <gregcnc> beyond that, who else would have a better chance of knowing what they designed?
[13:40:56] <gregcnc> even old grease would still be present, so maybe they did use oil
[13:41:56] <jesseg> gregcnc, well, umm, a lot of companies throw out all the old manuals for discontinued products and with employee turnover, it is quite common that contacting a manufacturer of a discontinued product is absolutely worthless. Heh, it's often worthless for a in-production product LOL.

[13:42:43] <MrHindsight> try contacting them, then post pics of the bearings
[13:42:51] <gregcnc> i get that, but some places are actually organzed
[13:43:02] <gregcnc> have you taken this spindle apart?
[13:43:08] <jesseg> So, in the case of a discontinued product where the manufacturer doesn't even acknowledge having built it and is of zero help, it's more help to ask a random guy on the street, and it's even more likely to be helpful to ask on a forum of seasoned industry experts such as yourself :D
[13:43:35] <jesseg> gregcnc, oh yeah I took it apart, flushed the bearings and got them nice and clean. Trust me, whatever grease was in there is not in there anymore.
[13:43:48] <gregcnc> so they were greased
[13:43:56] <jesseg> no idea
[13:44:04] <gregcnc> what did you wash away?
[13:44:26] <jesseg> well I knew there was swarf in them and that was what I was flushing out.
[13:44:38] <jesseg> If there was grease it was so little left after all these years I didn't see it.
[13:44:47] <gloops> well, you cant hurt anything by oiling them for now
[13:45:07] <gregcnc> generally, grease doesn't evaporate into nothing
[13:45:18] <gloops> England v Croatia coming up!
[13:45:59] <gregcnc> I'd guess that if there wasn't a means provided to oil regularly, it was greased for life of the bearings
[13:46:31] <jesseg> gregcnc, well, they could have put in just a small bit so the high speed spindle didn't just throw it all over. And with years of engraving dust (before I had this thing) it could have absorbed it.
[13:46:56] <jesseg> they are not sealed bearings. They don't have rubber seals, just little metal plates and little clips that hold them in
[13:47:00] <jesseg> gregcnc, but you have my curiosity up now.. please, if you might be so kind, I would so love to hear about the last high speed dry running ball bearing you saw or read about.
[13:47:16] <gregcnc> I didn't say high speed
[13:47:45] <jesseg> Ahh, well, highest speed one you seen or heard of then :D
[13:48:10] <MrHindsight> unlikely it used bacon fat
[13:48:10] <gregcnc> I can't think of any specific application off the top of my head either, but have read about. even water for lube
[13:48:28] <jesseg> yeah there's tons of clever tricks
[13:48:45] <jesseg> I really like the idea of a fluid bearing - total non contact, very little wear
[13:48:54] <MrHindsight> but imagine a shop that smells of bacon
[13:49:32] <gregcnc> https://www.gmnbt.com
[13:50:14] <gloops> if theyre standard bearings you can get some more anyway
[13:50:22] <gregcnc> bearings, greased for life, usually last long enough

[14:35:27] <gregcnc> "it doesn't actually change gears"

[14:36:16] <_methods> still pretty cool
[14:36:54] <fragalot> performs best at high loads too iirc
[14:37:46] <gregcnc> definfitely an interesting idea, I just don't know how well it will shift
[14:38:07] <fragalot> probably be fine if you let off the power whilst shifting
[14:38:31] <_methods> https://shop.bicymple.com
[14:38:37] <_methods> no chain required lol
[14:39:13] <fragalot> that looks really uncomfortable
[14:39:25] <_methods> it makes my brain hurt looking at it for some reason
[14:39:45] <_methods> like those pictures people draw of things from memory
[14:39:49] <gregcnc> does it actually sell? that's been around for a few years?
[14:40:30] <Rab> There's no way that thing can hold together under load. Or under typical road conditions of dirt and debris.
[14:40:49] <fragalot> Rab: the gear mechanism or the retarted bike?
[14:41:06] <Rab> fragalot, the ceramicspeed thing.
[14:41:22] <fragalot> I see no reason why it wouldn't
[14:41:30] <fragalot> whether the wear is lower than on a chain is a different question
[14:41:34] <gregcnc> torque is quite high
[14:41:41] <gregcnc> the tiny bearings?
[14:41:58] <fragalot> gregcnc: needle rollers should be fine
[14:42:22] <gregcnc> and 3-4x as wide
[14:43:04] <fragalot> the load put onto the tiny pin of a chain isn't exactly minimal either tbh
[14:43:50] <Rab> The force of the bearings against the sprocket plate is trying to lever them apart, with the bearings riding up the teeth. The presumption is that that force can be channeled into turning the plate, but I think both the plate and the driveshaft are liable to flex.
[14:44:03] <gregcnc> when bike at walmart have them,,,,,
[14:45:15] <Rab> I believe it would require some extraordinary materials science to produce a plate and driveshaft so stiff that all the force is transmitted at 99% efficiency, given so much torque on such a tiny contact area.
[14:46:04] <gregcnc> that's why they are selling the idea vs developing it
[14:46:26] <fragalot> Rab: that is indeed the main issue I can see too
[14:46:56] <fragalot> making the frame and driveshaft rigid enough is one thing, but making the wheel rigid enough too may require something else
[14:47:45] <MrHindsight> what Rab said ^^
[14:48:44] <MrHindsight> more bigger sprocket plate becomes flywheel
[14:50:53] <MrHindsight> I'd like to see it on a road under load

[17:38:14] <jesseg> gregcnc, well you were right - Newing-Hall did respond - and after I sent him dimensions of bearing, confirmed they can sell me new bearings for $40/ea if needed, and that they do have a special grease they put in their but he couldn't tell me what kind it was. He even contacted the bearing manufacturer to ask them about the prospect of me cleaning and re-lubricating the bearings. The manufacturer rolled twice in their grave, climbed out and offered to r
[17:38:14] <jesseg> ebuild the bearings in their class 100 clean room for $5-$10 if I mailed them to them.
[17:38:43] <gregcnc> well dang
[17:38:51] <gregcnc> seems fair
[17:38:56] <jesseg> lol absolutely
[17:39:11] <jesseg> so I still don't know what kind of grease but at least I know they probably did have grease LOL.
[17:39:42] <gregcnc> probably Kluber of some sort
[17:39:53] -!- phiscribe has quit [Ping timeout: 244 seconds]
[17:40:45] <jesseg> so I figure I'll try a little bar & chain oil since it's rated at 60 MPH (that's 96km/h!!) and just see what happens. If it gets hot then I'll perhaps try some Timken's High Speed Spindle Grease or maybe some clarified non-salted organic butter I don't know :P
[17:44:00] <Rab> There's some nasty stuff in bar oil, tackifiers etc. I wouldn't use it in spindle bearings.
[17:46:08] <gloops> high melting temp grease
[17:46:34] <gloops> like wheel bearing grease
[17:47:16] <jesseg> Rab, what problems would you expect with bar oil in a small spindle bearing?
[17:49:41] -!- andypugh has joined #linuxcnc
[17:53:02] <jesseg> yeah gloops there's nasty stuff in bearing grease, like alkali metal soap LOL
[17:54:12] <Rab> jesseg, I hypothesize that the tackifiers would work against proper flow of the oil at high speeds, resulting in poor lubrication and hot spots.
[17:55:28] <Rab> This might be appropriate: https://www.3inone.com
[17:56:11] <jesseg> I wonder if Kluber would also not flow right since it's a soaped up gel
[17:56:18] <Rab> But I think you would need frequent re-oiling. I think the proper solution is really to pack the bearings with high-speed grease.
[17:56:38] <jesseg> yeah could be
[17:56:45] <gloops> jesseg are these modular bearings, like - you can buy a new set off the shelf?
[17:57:23] <Rab> If you're getting in there to repack them, might as well replace them.
[17:57:31] <jesseg> gloops, $40 each from Newing Hall. I cannot find them listed on any other vendor. They are super thin - 0.5"ID and 0.75OD, 0.196" thick.
[17:57:55] <jesseg> At $80/set with as easy as it is to take apart I'd definitely try repacking them :D
[17:58:09] <Rab> OK, fine.
[17:58:36] <gloops> yes, if theyre good, worth greasing them, at those prices
[17:59:58] <jesseg> they seem good, a little more noisy than brand new bearings, but not that bad and seem to have no slop and spin really free
[18:00:48] <jesseg> so for my once in a while use they should last a while

[18:41:04] <jesseg> well, it's not the $20, it's that they'd need to be forced out of the spindle tube, and there's no way to press on the outer race for removal... and I am worried about damaging things if I press them out via the inner race.
[18:41:22] <jesseg> but maybe I'm overthinking that too :D
[18:41:33] <jesseg> that is a handicap of mine :P
[18:45:21] <gregcnc> in that type of a design there simply is no need to push out a good bearing, so your press where you can and install new
[18:45:56] <gregcnc> steel housing?
[18:46:21] <`Wolf_> hmm, that does say 3/4” right http://a.co … mic one and its 0.6675” >.<
[18:46:51] <`Wolf_> 17mm
[18:47:15] <`Wolf_> thats sorta close…
[18:47:28] <gregcnc> 6003 are 17x35x10mm always
[18:48:49] <`Wolf_> … didn’t even notice that, was ordering in a hurry
[18:53:06] <jesseg> gregcnc, housing is either steel or stainless steel, looks like stainless to me.
[18:55:30] <jesseg> but it could just be steel that was polished and never rusted a speck in 20 years or whatever, but I'm not buying that story :P
[18:58:28] <`Wolf_> same dumb ass seller has 6202 listed at 5/8”….

[19:05:09] <`Wolf_> bearings being the wrong size isn’t the end of the world, just a pain in the ass, I going to be lazy and use 3/4 stock for axles on project lol
[19:06:52] <andypugh> Metric bearings have metric dimensions. Why would you expect otherwise?
[19:07:52] <`Wolf_> because it was 6am when I hit the order and the things are listed as “M-jump 10 Pcs ID 3/4" x OD 1-3/8" Flanged Ball Bearing,Double Sealed,Widely used in Lawn Mower, Wheelbarrows, Carts & Hand Trucks Wheel Hub - F6003 2RS”
[19:08:52] <andypugh> Imperial bearings have names like KLNJ3/42RS
[19:10:07] <`Wolf_> I didn’t even notice the bearing number in the listing, was in a hurry to get order set for same day delivery before I got some sleep
[19:10:17] <andypugh> Though, now I come to check, I found… https://simplybearings.co.uk(1630RS)/product_info.html
[19:10:41] -!- HSD has quit [Quit: Leaving]
[19:11:10] <andypugh> So that could esaily be mistaken for a 6302
[19:12:15] <`Wolf_> bore size is listed in the product description 3 times, didn’t think I needed to double check the bearing number lol
[19:13:11] <andypugh> Yes, you have been sent something “not as described” and should get a refund.
[19:13:23] <`Wolf_> https://www.amazon.com
[19:13:37] <`Wolf_> seems they don’t understand bearing sizes
[19:19:37] <`Wolf_> well, on the plus side I can turn down the shafts to a shoulder and won’t have to put stop rings on them lol
[19:26:13] <`Wolf_> not critical application anyways https://i.imgur.com =D
[19:26:26] <`Wolf_> large RC toy
[19:29:54] <hazzy-lab> That IS large!
[19:30:20] <`Wolf_> actually its the same size as my rc truck…
[19:31:41] <`Wolf_> https://i.imgur.com
[19:33:23] <`Wolf_> I need to come up with a creative way to add cleats to the tracks tho

[20:02:52] <`Wolf_> I should be working on the lawn mower
[20:03:13] <`Wolf_> 180mm x 72mm pitch, 39 link https://i.imgur.com
[20:04:24] <jesseg> is that for yo ur new RC mower?
[20:04:55] <`Wolf_> yeah, using 2 right angle wheelchair motors and a 13hp deck
[20:05:06] <jesseg> LOL cool
[20:05:41] <`Wolf_> its that or I’ll be mounting the tracks on a hydraulic drive mower
[20:06:39] <`Wolf_> only issue with that is it would be wide a hell
[20:08:03] <`Wolf_> 52”/1.3m cutting deck + 2x 7”/180mm tracks…
[20:09:47] <`Wolf_> plus side, drive control is easy with the hydro, just toss two 1/5 scale rc servos on the hydro pump levers, relay for the deck clutch, relay for start and kill switch
[20:10:19] <`Wolf_> FPV camera so can mow from the AC in the house...
[20:15:51] <jesseg> "My lawnmower has air conditioning." LOL.

[20:22:57] <andypugh> `Wolf_: can’t you install Roomba software?
[20:23:15] <`Wolf_> jesseg: this is the real reason for the rc mower https://youtu.be much hill
[20:23:49] <`Wolf_> everyone asks me that, I don’t want a 800lb mower that navigates by brail
[20:24:09] <andypugh> Does it have a gyro?
[20:24:37] <`Wolf_> roomba works off bumper sensors
[20:25:16] <andypugh> That was a diffeent question :-)
[20:25:25] <`Wolf_> lol
[20:25:40] <andypugh> In the first video it seems to be needing a lot of correction. A rate-gyro might help with that
[20:26:08] <andypugh> (It made controlling our RobotWars robot much easier)
[20:26:11] <`Wolf_> no its all manual drive, no gyro, correction needed due to the hill, like 30%+ grade
[20:26:27] <`Wolf_> plus trying to hold the phone to vid while driving
[20:27:24] <andypugh> If you use an RC transmitter that understands V-tail and fit a gyro between the reciever and servos then it will tend to track straight unless you actively turn.
[20:27:41] <`Wolf_> I was using a v-tail mix for that
[20:28:02] <andypugh> So you are nearly there. Gyros are cheap. (and tasty)
[20:28:16] <`Wolf_> but not sure how that would work, most gyros are only one channel
[20:28:43] <`Wolf_> I would have to adapt a flight controller with v-tail mix onboard
[20:28:55] <andypugh> I am not sure either, but we definitely had one in the robot. (someone else did the electronics)
[20:29:04] <`Wolf_> and hope the vibes from the mower deck doesn’t throw everything off
[20:29:23] <`Wolf_> I have a tail gyro in one of my 1/16 rc cars
[20:29:35] <`Wolf_> too fast to try to control otherwise
[20:31:16] <andypugh> Google is not helpiong, but we definitely had V-tail in the transmittter and a gyro in the robot.
[20:31:34] <`Wolf_> https://i.imgur.com someone had the bright idea to stuff a 1/10 scale brushless in to it running 3s lips
[20:31:39] <`Wolf_> lipo
[20:33:25] <`Wolf_> yeah, not sure how they might have done it, more likely with a MCU + gyro sensor and some coding
[20:34:58] <SpeedEvil> I was about to say 'doesn't the can get stuck on stuff'
[20:35:00] <SpeedEvil> :)
[20:35:11] <andypugh> Pretty sure it was off-the-shelf (this was 1999)
[20:35:26] <`Wolf_> ooo hmm
[20:35:38] <`Wolf_> so no electronic esc
[20:36:07] <`Wolf_> er no electronic motor control I mean
[20:36:25] <SpeedEvil> https://www.youtube.com alternative for grass trimming
[20:36:44] <`Wolf_> lol
[20:37:00] <andypugh> We had some RC-servo to digital-potentiometer boards driving golf-cart controllers.
[20:38:05] <`Wolf_> I wonder if they make a v-tail gyro
[20:39:14] <`Wolf_> seems they do https://www.towerhobbies.com
[20:39:35] <`Wolf_> I think I’m using a delta mix
[20:40:40] <`Wolf_> least on the pain in the ass DX6

[21:53:00] <`Wolf> and those amazon bearings, I sent the seller a message, full refund on order =)
[22:05:11] <Lcvette> anyone using a WHB04-L wireless pendant?
[22:06:10] <`Wolf> http://wiki.linuxcnc.org
[22:06:21] <`Wolf> I’m not but I have been thinking about it
[22:07:00] <`Wolf> I’m cheap so I have been using a wireless game pad I already had
[22:07:14] <Lcvette> lol
[22:07:32] <Lcvette> yeah I've been there and a 35 page that earlier as well
[22:07:43] <Lcvette> they somewhat contradict each other

[22:09:48] <Lcvette> missed that one let me check
[22:10:50] <`Wolf> I remember needing to look all over to get my usb joystick to work https://i.imgur.com
[22:12:27] <pfred1> USB is my next project
[22:13:02] <`Wolf> I totally forgot about pendant for my cnc plasma build…
[22:13:14] <`Wolf> guess I should get one of those ordered lol
[22:14:28] <`Wolf> wow they are cheap now, $90 from amazon
[22:15:09] <Lcvette> yeah
[22:15:19] <Lcvette> I've had none for a few years now
[22:15:28] <Lcvette> mine*
[22:15:43] <`Wolf> use to be $150+ wasn’t it?
[22:17:53] <Lcvette> yeah o think i paid $159 for mine
[22:18:29] <`Wolf> so all the buttons are mapable
[22:19:55] <pfred1> too bad they're not maple
[22:20:05] <`Wolf> :P
[22:20:10] <pfred1> then you could lick them and they'd taste good
[22:20:44] <pfred1> I am a SPDIF convert
[22:20:53] <pfred1> this stuff sounds amazing
[22:21:35] <`Wolf> I think my plasma build is going to need that pendant
[22:21:59] <pfred1> I wish water jet was DIYable
[22:22:03] <`Wolf> I’m thinking about putting everything in the machine carriage
[22:22:07] <pfred1> plasma kinda sux
[22:22:19] <`Wolf> mini itx and all
[22:22:35] <`Wolf> yeah kinda
[22:22:42] <`Wolf> except the cost per cut
[22:22:47] <`Wolf> I think its a bit less
[22:22:50] <Lcvette> what torch type
[22:22:53] <pfred1> I was BSing with a guy that had a water jet
[22:23:10] <`Wolf> using a hypertherm w/ machine torch
[22:23:14] <pfred1> he said he stacked steel on the table a foot tall and cut through all of it at once
[22:23:37] <`Wolf> yep, I went to see a demo of the o maxx machines
[22:23:45] <pfred1> it's a shame the machine cost over a million though
[22:24:14] <pfred1> but what beautiful cuts like someone polished it
[22:24:16] <Lcvette> blowback start?
[22:24:17] <`Wolf> guy brought in a 8” thick chunk of aluminum and they cut it, nice straight kerf
[22:24:31] <`Wolf> HF start i think
[22:24:36] <pfred1> I swear the guy didn't sleep
[22:24:50] <pfred1> to pay the bank he had to run it 24/7
[22:24:56] <`Wolf> lol
[22:25:18] <`Wolf> one I looked at was only $80k I think
[22:25:20] <Lcvette> tuning yet?
[22:25:29] <Lcvette> running*
[22:25:37] <`Wolf> no, still theory right now lol
[22:26:04] <Lcvette> i had nightmares with HF start
[22:26:13] <pfred1> wow adding this surround sound system was totally worth it
[22:26:17] <Lcvette> had to get a blowback start machine
[22:26:28] <`Wolf> I know I can disable the HF start on the hypertherm
[22:26:43] <Lcvette> ok good
[22:26:55] <pfred1> HF start is nice
[22:27:03] <`Wolf> its a older powermax1000
[22:27:04] <Lcvette> except for cnc
[22:27:08] <pfred1> pfft
[22:27:18] <pfred1> my BOB is noise immune
[22:27:30] <`Wolf> so it has gouge mode with no HF I think
[22:27:54] <pfred1> I have one of those crappy Chinese air spindles and it doesn't phase it
[22:28:19] <Lcvette> big difference between hf start and spindle
[22:28:22] <`Wolf> I’m hoping having most of the control all nicely packed in to one box might help
[22:28:26] <pfred1> I didn't have to put caps on the motor or anything
[22:28:53] <pfred1> just make your system not so flighty
[22:29:05] <Lcvette> i tried everything
[22:29:05] <pfred1> make it so it needs some current to fire
[22:29:08] <`Wolf> only antenna on the system will be the lead to the THC stepper
[22:29:28] <pfred1> I used pull up and pull down resistors
[22:30:08] <pfred1> so it needs a couple real milliamps to do anything
[22:30:30] <Tom_L> Lcvette, hoz it goin?
[22:31:32] <Lcvette> Tom_L: what up man
[22:31:43] <Tom_L> get your mill goin yet?

[23:14:44] <roycroft> are there a lot of folks who have 3d printers that they run with linuxcnc?
[23:14:51] <roycroft> i don't see much talk about that
[23:15:04] <roycroft> mostly traditional subtractive machines
[23:15:53] <`Wolf> lcnc seems like it would be a pain for 3d printer w/ all the firmwares out for arduino and smoothie
[23:17:50] <`Wolf> I have 3d printer running ramps/marlin firmware and a 2.5W laser running on smoothie, both IMO work fine for that sorta thing w/ no real gain running them with linux cnc
[23:18:17] <roycroft> i know next to nothing about 3d printers at this point
[23:18:47] <roycroft> i need some small parts that i can purchase for way too much money that are commercially 3d printed
[23:18:51] <Tom_L> 2024 doesn't machine that well does it?
[23:18:53] <`Wolf> $40 for arduino based ramps board w/ lcd and 3x stepper drivers
[23:18:55] <Tom_L> seems kinda gummy
[23:19:06] <`Wolf> yeah it is
[23:19:09] <roycroft> it makes sense to me to consider getting a 3d printer and making them myself
[23:19:44] <`Wolf> yeah, thats a good use case for a 3d printer
[23:20:11] <roycroft> they would be best made of nylon
[23:20:28] <roycroft> and what little i know means i need an all-metal extruder for nylon
[23:20:40] <roycroft> and that doubles the cost of a low-end 3d printer
[23:21:06] <`Wolf> if you scratch build the printer the cost will be lower then a low end unit
[23:21:18] <roycroft> that's what i figured
[23:21:26] <roycroft> hence my question about using linucnc
[23:21:30] <roycroft> linuxcnc
[23:21:34] <`Wolf> pay $250 for $75 in parts lol

[23:23:01] <roycroft> i really only need something that can print 100mmx100mmx100mm for now
[23:23:05] <roycroft> so it could be pretty small
[23:23:30] <`Wolf> my printer was $700…. with what I know now, I wouldn’t even think of paying 1/2 that for a printer
[23:23:58] <pfred1> yeah it seems like there's good printers today for about $200
[23:24:22] <roycroft> i think the all-metal extruders themselves cost more than $200
[23:25:29] <roycroft> but when i'm looking at 4 parts that cost $25 each, and i might need to buy 4 of those parts 5-6 times in all, investing in a 3d printer isn't a bad idea
[23:25:40] <roycroft> there's probably $2 worth of nylon in each part
[23:26:10] <pfred1> filament is expensive
[23:26:12] <`Wolf> well, all ya need is ramps kit, 4 nema 17 steppers, threaded rod x2 or acme if you want 1st class, V slot extrude (quiet) + wheels or linear rails of some sort, PSU, and the hot end/extruder which I would look at the titan aero
[23:26:35] <roycroft> i'm talking about parts that are essentially cylindrical
[23:26:43] <roycroft> they're 19mm in diameter
[23:26:56] <`Wolf> sounds like a part to lathe make
[23:26:59] <roycroft> and about 50mm long
[23:27:17] <roycroft> they're somewhat complex parts to make
[23:27:38] <roycroft> i'm just talking about overall dimensions in reference to the cost of the filament
[23:28:00] <`Wolf> ok, what tolerance needed?
[23:28:21] <roycroft> 0.1mm would be ideal
[23:28:26] <roycroft> 0.3mm would probably be acceptable
[23:28:36] <`Wolf> thats doable on 3d fdm
[23:30:10] <`Wolf> https://i.imgur.com PETG printed part, led lens dimensions direct from calipers into cad, right to the printer, just had to clean the seam flash out of the holes and tight slip fit
[23:30:14] <roycroft> yeah, i don't think i'm asking for too much
[23:30:15] <Tecan> great success for musical printing https://www.thingiverse.com
[23:30:27] <Tecan> puts m300 at nth line in gcode
[23:31:03] <`Wolf> 4 front screw holes are ugly because unsupported at the top and PETG doesn’t bridge well
[23:33:32] <roycroft> i'm off to the oregon country fair tomorrow
[23:33:43] <roycroft> i'll have a lot of free time over the next few days
[23:34:00] <roycroft> so i checked out some 3d printing books from the library today
[23:34:03] <`Wolf> back side of that thing https://i.imgur.com
[23:34:15] <roycroft> i'll probably know a bit more about them after this weekend
[23:34:26] <`Wolf> not much to them
[23:34:42] <roycroft> sounds like you're suggesting linuxcnc might not be the best software to drive one
[23:35:11] <roycroft> that there are some common arduino/rpi drivers for them
[23:35:21] <`Wolf> yeah, 3d printing firmware has all the stuff figured out already
[23:35:58] <roycroft> i'm assuming i can model in solidworks and there will be some software that can read my solidworks files and do the slicing/gcode generation
[23:35:59] <`Wolf> http://a.co
[23:36:54] <`Wolf> there is more advanced stuff like smoothie and whatnot but dirt cheap and simple is that imo
[23:37:26] <roycroft> to describe the initial parts i need
[23:37:32] <roycroft> they're expanding bench dogs
[23:37:41] <roycroft> 19mm diameter cylinder
[23:37:50] <roycroft> it needs to expand to 20mm to lock in place
[23:37:55] <roycroft> there's a central bore
[23:38:13] <roycroft> a hex shaped recess on the bottom, that a hex bolt beds into
[23:38:23] <roycroft> a knob at the top will pull the hex bolt up
[23:38:25] <`Wolf> might be a issue with them breaking at the print layers
[23:38:28] <roycroft> the bottom will have vertical slits
[23:38:42] <roycroft> so that as the bolt is pulled up they will mushroom out
[23:38:57] <`Wolf> have to think of the 3d print like wood grain
[23:39:12] <roycroft> they could be printed sideways then
[23:39:27] <`Wolf> that would work
[23:39:42] <roycroft> and there would not be a lot of torque involved
[23:40:07] <`Wolf> I would make them out of acetal or nylon rod, just cnc the hex in to the bottom and slit them in a jig on the table saw
[23:40:26] <roycroft> i don't have a cnc mill yet
[23:40:37] <roycroft> that would make more sense if i did
[23:40:38] <`Wolf> yeah that makes it harder lol
[23:40:51] <roycroft> but yeah, i'm pretty uncertain about low end 3d printers
[23:41:01] <`Wolf> you could do the cylinder on lathe and print the base parts lol
[23:41:31] <roycroft> i know that the higher end ones, the ones that cost 5-6 figures, do really good work
[23:41:46] <roycroft> they mostly use laser sintering, i believe
[23:41:50] <`Wolf> yeah
[23:41:57] <`Wolf> thats a diffrent world IMO
[23:42:12] <roycroft> and that might be the world that makes sense to me for 3d printing
[23:42:13] <`Wolf> you can print rocket engine nozzles on those
[23:42:21] <roycroft> not that i would ever invest in one
[23:42:30] <roycroft> i'm not interesting in a 3d printer for a hobby
[23:42:32] <roycroft> interested
[23:42:42] <roycroft> if i build/purchase one it will be to make parts
[23:43:07] <roycroft> and maybe that's just not feasible on a small budget
[23:43:07] <`Wolf> make a drawing up and I’ll print parts and mail them, just pay for the flat rate box ;P
[23:43:35] <roycroft> i'll probably need them on a recurring basis
[23:43:40] <`Wolf> like i said also, can mix the build type
[23:45:06] <roycroft> some folks make these things out of wood
[23:45:38] <roycroft> and i can do that
[23:45:47] <`Wolf> the mandrel part sounds like a good for 3d print part, layers would work like stack of washers
[23:45:56] <roycroft> it just seemed like an opportunity to look into a 3d printer
[23:46:14] <`Wolf> the dog half not so much lol
[23:47:16] <roycroft> well, i figure that after the weekend i'll know a lot more about low end 3d printers
[23:47:34] <roycroft> and i may well be dissuaded of the notion to build/purchase one
[23:47:36] <roycroft> or not
[23:48:18] <`Wolf> it can be handy thing if you can cad the parts yourself
[23:48:57] <`Wolf> I’ve used mine to make fixtures for milling things
[23:49:09] <`Wolf> and the change gears for the lathe lol
[23:50:05] <`Wolf> https://i.imgur.com https://i.imgur.com
[23:51:51] <`Wolf> last thing off the printer, did this yesterday while I was milling stuff https://i.imgur.com
[23:58:58] <roycroft> those gears will be durable?
