[12:39:39] <IchGucksLive> hi all
[12:40:29] <IchGucksLive> gloops, FR is at the next level
[12:40:43] <IchGucksLive> gloops, HAM did hold back today
[12:40:49] <gloops> yes i think France are the team to beat
[12:41:06] <fragalot> Today, I learned about Polacolor filters
[12:41:07] <gloops> Belgium could beat Brazil
[12:41:27] <gloops> polarised colour?
[12:41:29] <IchGucksLive> fragalot, good for laser
[12:41:58] <IchGucksLive> fragalot, and lots of scanner Mediatech work that way
[12:42:57] -!- unterhausen has quit [Ping timeout: 252 seconds]
[12:43:03] <gloops> theres a chance that England could play France or Belgium in the final - all neighbours, world cup and 2 teams in the final next door
[12:44:18] <fragalot> gloops: yes, similar to a standard polarizing filter, except it affects one color only
[12:45:03] <IchGucksLive> fragalot, use off
[12:45:09] <gloops> ive got various cpls and some linear, tbh i never used them a lot
[12:45:28] <fragalot> gloops: Cokin P162 for example is a blue one
[12:45:37] <IchGucksLive> gloops, since yesterday all prices cncrrelated climb
[12:45:41] <fragalot> I might get one to see
[12:46:11] <IchGucksLive> HGH20 rail set 450Euros now from $20 Monday
[12:47:42] <gloops> 450 set for 20?
[12:48:18] <gloops> fragalot thats the thing with photography its all about the GEAR lol
[12:51:00] <fragalot> :-)
[12:51:13] <gloops> i got 1 piece of 100mm box section today, bloke had 2 2metre lengths, i asked if he was throwing them out - he said take 1 if you want 1
[12:51:20] <gloops> 1! he kept 1 lol
[12:52:06] <gloops> it will still be there going rusty in 5 years
[12:52:25] <IchGucksLive> gloops, monday 420 Euro &rail HGH20 incl Ballscrew now it is 450 at almost all BAY shops
[12:52:38] <gloops> ahh
[12:53:43] <IchGucksLive> gloops, but the BOSCH AL profile rails gone down from 175Euros to 135.- 12meter Cut
[12:54:22] <gloops> well, i wont be building anything cnc for a while
[12:54:22] <IchGucksLive> gloops, i got 5 orders from the mashine i did move last wendsday
[12:54:36] <gloops> see, it worked out well Ichs
[12:54:55] <IchGucksLive> some schools dident belive i guess
[12:56:16] <gloops> i better go and do a few things, want to watch the belgium game
[12:56:23] -!- gloops has quit [Quit: Leaving]
[12:59:21] <IchGucksLive> Wolf__, i did the first test on the low cost Education plasma
[12:59:42] <Wolf__> nice
[12:59:42] <IchGucksLive> Wolf__, complete including cutter 680Euros
[12:59:51] <IchGucksLive> let me upoad a video
[13:01:51] <fragalot> That's an impressive price point
[13:02:01] <fragalot> IchGucksLive: what size is it?
[13:02:09] <IchGucksLive> 510x510
[13:02:29] <fragalot> pictures? :D
[13:03:04] <IchGucksLive> VIDEO -> https://youtu.be
[13:03:44] <IchGucksLive> Wolf__, you get it 2
[13:03:56] <Wolf__> watching now
[13:04:40] <IchGucksLive> Plasma is a 275 S-cut
[13:05:02] <IchGucksLive> S-cut 50A 275 Euros including shipment
[13:06:06] <IchGucksLive> its a Trapezional LM16UU system
[13:06:32] <IchGucksLive> you can save even more if you curt the 60Euros pulling
[13:06:54] <IchGucksLive> but i dont like direct mount
[13:08:07] <IchGucksLive> 12x LM16UU at 26Euros for liniar bearing
[13:08:37] <IchGucksLive> 3x TB6600 at 8,5 etch
[13:09:57] <IchGucksLive> Wolf__, crap ?
[13:10:20] <Wolf__> for budget build looks good
[13:10:36] <IchGucksLive> workes fine up to 5mm
[13:10:49] <IchGucksLive> its low speed max 600mm/min
[13:11:12] <IchGucksLive> 1,9Nm at 24V
[13:11:33] <IchGucksLive> now i woudt go 48V DM556
[13:11:54] <IchGucksLive> then it shout move near 5m/min
[13:12:05] <IchGucksLive> but it ads 150 euros
[13:12:59] <IchGucksLive> fragalot, how does it look for you
[13:13:28] <IchGucksLive> this is ofcause lowest level you can go
[13:13:38] <IchGucksLive> lower woudt be TB6560
[13:14:10] <fragalot> IchGucksLive: looks pretty good for the price in my opinion
[13:14:24] <IchGucksLive> <- SMILES
[13:14:24] <fragalot> if I had the space I'd probably buy it
[13:14:44] <Wolf__> i’ll be using 3Nm nema23 @36v for my build, but its going to be a rail style w/ arm
[13:14:45] <IchGucksLive> i do not sell only build for education
[13:15:19] <IchGucksLive> Wolf__, go 48V
[13:15:29] <IchGucksLive> 500W one psu
[13:16:03] <IchGucksLive> Wolf__, i discoverd at digital Driver there is less emi fail
[13:16:19] <IchGucksLive> Wolf__, where in the world are you

[13:16:55] <Deejay> re
[13:17:03] <Wolf__> I have https://www.aliexpress.com sitting already
[13:17:48] <Wolf__> least I think thats it, not sure if its the same drivers
[13:18:42] <fragalot> IchGucksLive: it'd be educational for me as i've never owned a cnc plasma. :P :P
[13:19:55] <IchGucksLive> Wolf__, steppes are perfect
[13:20:20] <IchGucksLive> Wolf__, seatch for DM556d
[13:21:20] <Wolf__> mb45a drivers
[13:21:47] <Wolf__> https://i.imgur.com been sitting for 3yrs waiting for project
[13:22:27] <Wolf__> MB450A *
[13:23:49] <IchGucksLive> Wolf__, there is nothing wrong with it
[13:24:30] <IchGucksLive> Wolf__, all i say is analog drivers got some wear if the hight is not correct at firering
[13:24:57] <IchGucksLive> while the DM ones dont show this even at 10mm firering and moving into the part
[13:25:30] <IchGucksLive> i got all tested in the shop
[13:25:54] <Wolf__> I’ll keep that in mind
[13:25:56] <IchGucksLive> M542 Tb6600 MH860 Against the Real DM556d
[13:26:53] <IchGucksLive> i dont have a T version as it is maybe only the RS232 missing
[13:27:12] <IchGucksLive> but the real ones correct the Amps very good without tuning
[13:27:30] <IchGucksLive> and they run 3times the speed
[13:27:40] <IchGucksLive> on the same setup
[13:28:05] -!- Joe_Hildreth has joined #linuxcnc
[13:28:14] <IchGucksLive> all i can say
[13:28:21] <IchGucksLive> hi Joe_Hildreth
[13:28:43] <Joe_Hildreth> Howdy IchGucksLive
[13:29:16] <IchGucksLive> how is it in tennesie
[13:29:33] <IchGucksLive> im in germany
[13:29:51] <Joe_Hildreth> Have a question of parallel ports. As I understand IEEE 1284 defines two operating modes for the parallel port, EPP and ECP. I have two questions.
[13:30:06] <Joe_Hildreth> It is hot and humid and raining today. :-(
[13:30:22] <Joe_Hildreth> How about Germany?
[13:30:30] <IchGucksLive> bright sunshine
[13:31:16] <Joe_Hildreth> Does this mean that a port supports both modes and it is a matter of selecting which mode, or are ports sold as one or the other EPP or ECP?
[13:31:44] <Joe_Hildreth> Second question, does LCNC really care what mode the port is run in, EPP or ECP?
[13:32:25] <Joe_Hildreth> I am working on my next installment of CNC for the home hobbyist and this one is about I/O options.
[13:32:29] <jesseg> Joe_Hildreth, well the early SPP (Standard Printer Port) didn't support either. Then some chipsets came out that supported one, or both. or maybe other standards. Nowdays I'd guess that all of them support most of the common standards.
[13:32:59] <jesseg> Joe_Hildreth, are you communicating with an FPGA or just driving steppers with a dumb stepper driver?
[13:33:35] <Joe_Hildreth> From a hobbyist point of view, where money is an issue. I suspect that the computer being put in use will be no older than 10 years.
[13:33:37] <IchGucksLive> Joe_Hildreth, EPP is up to 1Mbit
[13:33:56] <Joe_Hildreth> Steppers with software stepping.
[13:33:57] <IchGucksLive> Joe_Hildreth, while ecp is better for centronic devices
[13:34:31] <jesseg> A lot of the advances were for the purpose of higher speed bi directional DMA controlled data transfer I think
[13:34:34] <IchGucksLive> Joe_Hildreth, EPP is best to set and you can go easy 30000 steps per second
[13:34:52] <Wolf__> lol I think one of my Lcnc machines is over 14yrs old
[13:34:54] <Joe_Hildreth> If the computer has an onboard PP, would it most likely support both modes?
[13:34:57] <jesseg> well I gotta run, cya all later :D
[13:35:10] <Joe_Hildreth> CYA jesseg
[13:35:24] <IchGucksLive> Joe_Hildreth, i build around 100 mashines a year and all are fine
[13:35:42] <IchGucksLive> and ofcause 95 of this are on parport
[13:36:09] <IchGucksLive> depending on setup and precision 12m/min
[13:36:11] <Joe_Hildreth> That is my gut feeling, if it has an onboard PP then it is probably just fine. The LCNC documentation does not talk about EPP or ECP ports
[13:36:18] -!- gloops has joined #linuxcnc
[13:36:24] <IchGucksLive> or easy 5m/min at 0,01mm precision
[13:36:47] <Joe_Hildreth> phone, brb
[13:36:56] <IchGucksLive> Joe_Hildreth, parport is standard set to EPP
[13:37:14] <Wolf__> fail I was wrong, 2007 build
[13:37:18] <IchGucksLive> im off BYE Gn8 from Germany
[13:37:30] -!- IchGucksLive has quit [Quit: Leaving]
[13:37:48] <Wolf__> running step gen moving my mini mill
[13:38:00] <Joe_Hildreth> back ... thanks IchGucksLive
[13:39:14] <Joe_Hildreth> I guess my biggest question: Does the onboard parallel port support both EPP and ECP or are they typically on or the other?
[13:40:53] <Joe_Hildreth> Wolf: The episode I am working on is a general discussion of the I/O options available for LCNC. These videos are targeted towards new users. Here is the playlist of what I have completed ...
[13:41:11] <Joe_Hildreth> https://www.youtube.com
[13:42:41] <Joe_Hildreth> I intend to talk briefly about Uspace and Ethernet driven cards, PCI, PCIe addon cards and the parallel port. Will focus on the parallel port simply because everyone has access to it and to but them are cheap and is the simplest way for someone to learn the system with.
[13:43:01] <Wolf__> maybe pcw_home can answer some of that
[13:43:51] <Wolf__> really its starting to get harder to find cheap mobo that have parallel ports
[13:43:57] -!- Motioncontrol has joined #linuxcnc
[13:44:23] <Joe_Hildreth> pcw_home has given me some great help in the past.
[13:44:45] -!- DaPeace has joined #linuxcnc
[13:44:53] <Joe_Hildreth> True, but parallel port add on cards are still plentiful and cheap.
[13:45:14] <Wolf__> my last build was a mini itx so no room for cards lol
[13:45:50] <Joe_Hildreth> On board PP or using ETH or something else?
[13:47:49] <Wolf__> has onboard pp but I’m leaning towards mesa ETH https://i.imgur.com (12” level for scale)
[13:49:18] <Wolf__> plus the jitter and latency is a bit high for doing step gen on it
[13:49:20] <Joe_Hildreth> Gotcha. What size is that Stepper, looks like a 600 oz-in or so. What are your driving?
[13:49:40] <Wolf__> thats a 700w 190v servo
[13:50:04] -!- swarfer has joined #linuxcnc
[13:50:46] <Wolf__> I have a stack of nema 23 4Nm that are going on a cnc plasma and X2 mini mill build
[13:50:50] <Joe_Hildreth> ok. I have no experience with servos.
[13:51:05] <Wolf__> I dont either =D
[13:51:10] <Joe_Hildreth> hahaha
[13:51:50] <Joe_Hildreth> so there are two type correct. Step driven servos and PWM servos? That sound right?
[13:53:03] <Wolf__> I blindly ordered a bunch of surplus stuff off ebay back in ’04 thinking I was going to do a router build, never did it because the how to info wasn’t quite like it is now, these are analog drivers w/ the servos I have
[13:53:30] <Wolf__> https://i.imgur.com
[13:53:37] <gloops> Belgium v Brazil!
[13:54:11] * fragalot is looking for a little adapter plate to turn his tripod into an arca swiss compatible one
[13:54:27] <Wolf__> the step driven servos I think are mostly the closed loop standalone?
[13:55:00] <gloops> fragalot print a quick release fitting
[13:55:29] <fragalot> gloops: not sure if I want to put a €6000 camera assembly onto a 3D printed part
[13:55:38] <fragalot> the tripod already has a quick-release
[13:56:01] <fragalot> but I need a spacer so my black widow belt holster adapter plate works on it
[13:56:02] <Joe_Hildreth> I am on my second router build. http://www.myheap.com
[13:56:03] <gloops> 6000 quid - only acceptable if youre doing weddings
[13:56:06] <fragalot> and the adapter plate is acra compatible
[13:56:21] <Wolf__> ^ keep in mind most quick release are cams, really good at crushing 3d prints
[13:56:32] <gloops> well mill an ally one then
[13:56:50] -!- swarfer has quit [Quit: swarfer]
[13:56:51] <fragalot> gloops: I would if I wasn't going to go on holiday before the damn RF45 is put together again :D
[13:57:32] <Wolf__> nice Joe_Hildreth, that thing looks like a beast
[13:58:51] <gloops> any give in the z axis Joe_Hildreth?
[13:59:04] <Joe_Hildreth> It has a 38" x 42" cut area. It does what I need it to do. But I am really still a newbie in a lot of ways.
[13:59:54] <Wolf__> toy sized https://i.imgur.com
[14:00:25] <Joe_Hildreth> There is some give on very heavy cuts. There are modifications I want to make to the machine to make it more rigid, but it is primarily used on wood and plastic.
[14:01:21] <gloops> hmm, cant really see what kind of beam for the gantry, but z travel looks quite a lot - gantry/bearings need to be stiff for that
[14:02:12] <Joe_Hildreth> Toy sized or not, at least you can mill metal. I can take light cuts on Aluminum but that is about it.
[14:02:34] <Joe_Hildreth> http://www.myheap.com
[14:02:46] <Wolf__> that x1 micro mill can do massive 0.2mm doc
[14:03:11] <Wolf__> its not solid what so ever lol
[14:03:14] <Joe_Hildreth> Here is the build log: http://www.myheap.com
[14:04:56] <Joe_Hildreth> I have a Burke #4 milling machine that I need to recondition. It is a late 40's model I think. Horizontal but better than nothing. I have an Atlas 10F. between the two, I am hoping to make some modifications to the machine that I built to make it more rigid
[14:05:04] <Joe_Hildreth> and replace the router with a spindle.
[14:06:47] <Wolf__> I picked this up over the winter, https://i.imgur.com ‘80s era Jet mill and Enco 12x37, hell of a upgrade from the harbor freight micro mill and 7x10 lathe =)

[14:57:08] <Tecan> is there a good gear calculator for linux ?
[15:02:07] -!- guest_557 has quit [Quit: Page closed]
[15:02:47] <gloops> there are some simple gear calculators you can use on the web, what kind of gears?
[15:03:26] <fragalot> Tecan: http://woodgears.ca works well enough for simple gears
[15:03:32] <Tecan> im not picky, but i would like to convert 15 rpm to 4 rpm
[15:04:33] <gloops> whats this for Tecan? spindle?

[15:27:10] <Wolf__> 4rpm spindle would have to be one hell big cutter =P
[15:28:16] <fragalot> :D
[15:28:50] <gloops> i didnt mean a cuttin spindle per se
[15:28:51] <Tecan> blender has a nice gear plugin but its lacking the rpm conversion
[15:28:57] <Tecan> and im not sure how to math it
[15:29:27] <gloops> the gear generator link gives rpm, the math is not difficult Tecan if you just want to calculate that
[15:32:04] -!- JT-Mobile has joined #linuxcnc
[15:32:08] <gloops> so, lets say we have some nice easy numbers...
[15:32:17] <gloops> like 15rpm - 5 rpm
[15:32:22] <JT-Mobile> hola from Houston
[15:32:31] <gloops> alls you have to do is divide 15 by 5
[15:32:36] <gloops> 3-1 ration
[15:32:47] <gloops> ratio
[15:33:50] <gloops> Brazil score...
[15:34:52] <fragalot> 3:1 is easy, non-integer CAN get complicated
[15:35:33] <fragalot> not that 15:4 is much harder :P
[15:35:42] -!- Motioncontrol has quit [Quit: Sto andando via]
[15:36:04] <Tecan> https://sourceforge.net looks neat
[15:41:16] <gloops> i suppose it depends whether you want a model of the gears to cut or print
[15:53:27] <gloops> Belgium!
[15:53:48] <fragalot> ?
[15:55:13] <gloops> won
[15:55:17] <Tecan> f-engrave works well for cutting out gear profiles. but yes ide be using it for printing
[15:55:19] <gloops> Brazil go home
[15:55:28] <Wolf__> wonder if that gggears would make the stupid 72mm pitch spur I had to pretty much hand draw
[15:55:46] <Tecan> there is also pygear
[15:55:57] <gloops> also inkscape
[15:56:00] <Tecan> https://sourceforge.net looked pretty fancy

[15:57:59] <Wolf__> i dunno about printing the gear I need, 1/4 of it, 5hr print
[15:59:03] <fragalot_> print on paper, stick to wooden surface, cut out by hand
[15:59:23] <Wolf__> well, I could laser it at that point
[15:59:33] <Wolf__> in one shot even =)
[15:59:41] <fragalot_> Do that then :P
[16:00:05] <Wolf__> 297mm outside diam
[16:02:05] <gloops> more satisfaction fretsaw though
[16:02:11] <gloops> from fretsaw
[16:02:47] <Wolf__> actually only printing part of it for test fit, if its good, then plasma out of 1/2” steel plate, then stack 2 to make it 1” thick after turning a bevel on the teeth
[16:03:36] <fragalot_> is the coarseness from plasma edges not an issue?
[16:04:09] <Wolf__> https://i.imgur.com probably not
[16:04:42] <fragalot_> oh ok
[16:05:50] <Tecan> i was thinking about remixing the gears from this to do 4 mm/s currently it does 1.2 which is enough to print at 0.31 layers 60mm/s from a 0.4 nozzle
[16:05:55] <Tecan> https://www.thingiverse.com
[16:06:18] <Tecan> if 3mm filament is used
[16:06:33] <Tecan> 3.32349725638639 for 1.75 mm filament
[16:06:33] <Tecan> 1.12377245359828 for 3mm filament
[16:06:56] <Tecan> the long numbers are mm/s needed to print for that speed
[16:07:15] <fragalot_> you mean meters?

[16:08:24] <fragalot_> bear in mind higher speed == higher torque required
[16:09:08] <Wolf__> this is a uses case for clearpath servos imo
[16:09:13] <Wolf__> =P
[16:09:44] <Tecan> another guy was able to do it ungeared at 10 mm/s at https://www.thingiverse.com
[16:09:49] <fragalot_> hehe
[16:09:49] <gloops> have a look at the sprockets on the typical chinese mountain bike - you can get away with a lot lol
[16:10:19] <Tecan> but im not sure it would be as strong as it should be.
[16:10:22] <fragalot_> I've always run the MGS extruder on mine, hasn't failed me yet
[16:10:25] <Wolf__> all i got is shimano
[16:10:44] <fragalot_> and that machine prints at 250mm/s with 3mm filament on a .4mm nozzle with no problems
[16:11:27] <Wolf__> I dont eve know what my printer is printing at lol
[16:13:16] <Wolf__> slow… 70mm/s infil
[16:14:21] <fragalot_> tbh I don't print at 250mm/s every day,.. the acceleration required to get there is too hard on the parts and I want to avoid premature wear just because I want to save an hour on a print that runs overnight anyway
[16:14:36] <fragalot_> once the whole table starts shaking you know you've gone too far
[16:14:58] <Wolf__> I must need a better table, its shaking right now lol
[16:15:07] <fragalot_> :D
[16:17:46] <Wolf__> need bigger printer https://i.imgur.com
[16:18:23] <fragalot_> or reduce infill / use rectilinear
[16:18:31] <fragalot_> if it's only for trial fit
[16:19:03] <Wolf__> yeah, its at 10% right now
[16:19:26] <fragalot_> still quite dense for honeycomb
[16:19:28] <Wolf__> I didn’t think to change infill
[16:20:08] <Wolf__> I’m usually printing parts to use
[16:22:37] <fragalot_> https://youtu.be seems I have an ancient video of the printer when I first built it, lol
[16:24:33] <fragalot_> https://www.youtube.com also turns out i've gone up to 360
[16:25:20] <fragalot_> god that sounds horrendous when doing the outside, hahahah
[16:25:54] <XXCoder> dual hotends eh
[16:26:01] <fragalot_> yes
[16:26:06] <XXCoder> cool
[16:26:26] <fragalot_> one is permanently set up with .4mm PLA, the other with .25 ABS
[16:26:35] <fragalot_> I never use the .25 to be honest
[16:26:38] <fragalot_> too slow
[16:26:47] <XXCoder> dual color setup why not?
[16:27:00] <fragalot_> because I don't care enough :D
[16:27:05] <XXCoder> lol ok
[16:27:48] <XXCoder> prusa fork of slic3r will have interesting new feature for wiping
[16:28:16] <XXCoder> it makes two parts for dual colors, only one is perfect colored, other is just used for wiping and as well make it a complete part
[16:28:33] <XXCoder> so you have free second part for backup or maybe give away to friend
[16:28:35] <fragalot_> my slic3r was already set up to wipe the nozzle at some point
[16:28:46] <fragalot_> oh, like that
[16:29:00] <fragalot_> interesting
[16:29:18] <XXCoder> yeah saw voideo of it. second part was kinda sloppy but it was complete
[16:29:29] <XXCoder> (sloppy color wise, it was fine print wise)

[17:13:00] <gloops> the ford ka was a dangerous flimsy death-trap
[17:15:23] <Wolf__> damn thats ugly
[17:15:47] <XXCoder> not as bad as other cars I saw
[17:16:11] <Loetmichel> gloops: was it?
[17:16:13] <XXCoder> tehres this suv I call "goblin face" because it has something that looks like goblin face in back
[17:16:21] <gloops> my mrs had an old type, the suspension is all rubber bushes
[17:16:34] <gloops> was scary sitting in it
[17:16:43] <Loetmichel> i know THAT feeling
[17:17:07] <gloops> i dont like having my knees touching the bulkhead
[17:17:08] <Loetmichel> my BMW has coilovers... screwed down SO low that the rubber bumpers are already squished ;)
[17:17:41] <gloops> one bump - pair of broken hips
[17:17:43] <Wolf__> I bet the wheels on my truck weigh more and have more metal then that KA has
[17:18:07] <Loetmichel> Wolf__: entirely possible
[17:18:14] <Loetmichel> if its a monster truck
[17:18:35] <Wolf__> just a ford F550

[17:19:33] <Loetmichel> Rab: a smart is a surprisingly sturdy shopping car(t)
[17:20:05] <Wolf__> I kinda want a smart car
[17:20:08] <Loetmichel> its neither meant for stock car races nor for the autobahn
[17:20:16] <Wolf__> with a ‘busa motor in it
[17:20:42] <gloops> i know the smart cars have strategic reinforcing, didnt seem to be any of that with the Ka, it would be safer in a shopping trolley
[17:20:59] <Loetmichel> Wolf__: i would settle for the 85kW brushless electric motor i found a few weeks ago on aliexpress.. ;)
[17:21:34] <Wolf__> yeah but where ya gonna put all the batteries in the smart lol
[17:21:42] <Loetmichel> under the seats
[17:21:57] <Loetmichel> its the only place where they CAN go acutally ;)
[17:24:28] <Wolf__> oh Loetmichel, https://i.imgur.com =D
[17:25:19] <Loetmichel> nice. did you resuze it?
[17:25:28] <Loetmichel> or just rotated the teeth?
[17:25:57] <Wolf__> one of the bed screws was hitting the back of the frame
[17:26:55] <Loetmichel> ah, so after shortening that you had more y travel?
[17:27:20] <Wolf__> yeah, was cutting 2cm of travel

[22:40:57] <XXCoder> wow very visually confusing took me a minute lol
[22:41:10] <XXCoder> flatting cast iron something feet?
[22:41:29] <skunkworks> it is the base (y axis) of a mill I have. truing it up
[22:42:03] <skunkworks> (well - giving me some reference points so I can put it together square. hopefully
[22:42:21] <XXCoder> yeah
[22:42:39] <XXCoder> did you indictate the support wall make sure its nice and 90 degree to tool?
[22:42:39] <Wolf__> milling the bondo off of it? =)
[22:42:40] <skunkworks> this casting was a lot better than the vertical column.. holes where pretty symetrical and things lined up with the ways
[22:43:34] <skunkworks> XXCoder: I milled the column base true to iteslf.. http://electronicsam.com
[22:44:12] <skunkworks> so hopfully after I add the riser - it should be 'close enough'
[22:44:23] <XXCoder> hope so :)
[22:44:25] <skunkworks> this thing needs about a 4 inch riser to make it functional
[22:44:57] <skunkworks> as it was - the spindle would could go 1" below the table (without a tool in it)
[22:45:20] <Tom_L> i had that issue to deal with on my homebuilt mill
[22:45:50] <Tom_L> i wanted it to go low enough a flycutter would reach the table but still have room for longer cutters
[22:45:52] <skunkworks> so I should be able to make the riser key the base and the z column
[22:45:53] <Wolf__> I should probably add a riser to my x2 build
[22:46:35] <skunkworks> I figure there is going to be a fixture plate and or a vise on the table. i don't want to give up too much room
[22:47:03] <Tom_L> i've got room to skin cut the sacrificial plate on mine
[22:48:11] <Wolf__> actually my Jet mill could probably use a lift kit
[22:48:31] <Tom_L> http://tom-itx.no-ip.biz:81
[22:48:42] <Tom_L> tried to make it flexible without slots
[22:50:26] <XXCoder> skunkworks: below? wasted space!
[22:50:36] <XXCoder> inch and half added maybe? heh
[22:51:21] <XXCoder> Tom_L: man your jaws look shiny lol
[22:51:35] <XXCoder> dont look like kurt though pretty similiar
[22:51:49] <Tom_L> shars
[22:52:21] <Tom_L> 4" for size reference
[23:03:14] <RyanS> does that table mounted enclosure help? my mill spews chips everywhere
[23:03:49] <Tom_L> yeah and i've made slip on risers that go a bit higher
[23:04:03] <Tom_L> helps quite a bit but doesn't catch it all
[23:04:15] <XXCoder> RyanS: depends on lots factors but foot higher than cutting area blocks large percentage of chips.
[23:04:24] <XXCoder> wear googles anyway
[23:04:36] <RyanS> I don't want to go to the trouble making room for a full enclosure
[23:04:48] <Tom_L> i don't have room for one
[23:04:52] <Wolf__> shower curtain
[23:04:54] <XXCoder> also, theres silly thing you can make that helps you do cleanup afterwards
[23:05:04] <XXCoder> use pvc pipes to make a frame and stand for it
[23:05:19] <XXCoder> you could block off areas from chip flying so easy to clean
[23:05:38] <Tom_L> use polycarbonate instead of plexi though
[23:07:39] <RyanS> but I have been putting off tramming the column to fix the 'nod' because it's out a tiny bit but not enough to ruin parts
[23:08:05] <Tom_L> i haven't checked mine lately but i got it pretty darn close
[23:09:07] <Wolf__> https://i.imgur.com mag mount chip shield helps on my machines

[23:11:14] <Wolf__> x2 spindle
[23:11:27] <Wolf__> sewing machine servo
[23:11:54] <Tom_L> were you the one trying to hack into one of those for speed control?
[23:12:32] <Wolf__> yeah and blew the board up lol
[23:12:41] <Tom_L> did you ever get that working?
[23:13:08] <Wolf__> not yet, I’ll figure out the speed control at some point
[23:13:15] <Wolf__> or just stmbl it

[23:14:34] <RyanS> looks a bit like a mad scientists den too, I like it
[23:18:10] <RyanS> Industrial sewing machines are cool,not multifunctional at all but fast
[23:18:55] <Wolf__> thats a 750W 190vdc brushless servo motor w/ controller, $220 delivered
[23:19:51] <Wolf__> made to remove the constant running clutch motor on the industrial sewing machines
[23:22:35] <Tom_L> aftermarket sherline has one very similar but they want way too much for it
[23:23:09] <Wolf__> were ya think i got the idea, saw those, then the sewing machine kits on ebay lol
[23:23:21] <RyanS> some industrial overlockers have a pneumatic blade to cut the edge. I would have thought they would use a linkage to the motor

[23:24:59] <Tom_L> those guys are nuts
[23:25:09] <Wolf__> thats the one
[23:25:22] <Tom_L> another 275 for the analog interface
[23:26:06] <Wolf__> + $30 for 220
[23:26:14] <Wolf__> and the units cost the same $$
[23:26:49] <Tom_L> i'd use a servo before i'd get one of those
[23:27:13] <Wolf__> https://i.imgur.com
[23:27:23] <XXCoder> its one of dumb sites with "live chat"
[23:27:37] <Wolf__> pretty sure speed control is just hacking in to the halls sensor feed
[23:27:53] <Wolf__> for the foot pedal not the servo halls
[23:28:44] <Tom_L> on the stock sherline control, the gnd is floating though so it requires another interface board
[23:28:59] <Wolf__> https://i.imgur.com
[23:29:08] <Wolf__> so, $3 arduino?
[23:29:58] <Tom_L> which wires are the pedal interface?
[23:30:07] <RyanS> closed loop steppers are cool ( literally too) it's not just about correcting missed steps, apparently double the torque of open loop, much higher rpm
[23:30:15] <Wolf__> ones in the little box w/ the green pcb
[23:30:42] <Tom_L> did you measure the voltage or signal at those wires?
[23:30:45] <Wolf__> oops blue board
[23:30:55] <Tom_L> yeah i see it
[23:31:40] <Wolf__> no I pulled it out to test, then the wire fell off the desk and the blue board hit the heat sink, which probably had 190v in it
[23:31:54] <Wolf__> or something
[23:32:03] <Wolf__> shit blew up either way
[23:32:53] <Wolf__> https://i.imgur.com
[23:32:57] <Wolf__> oops =)
[23:33:37] <RyanS> so if I were to cnc my BF30 (BLDC spindle), I could just remove the potentiometer and connect the input to the speed controller directly to the cnc controller
[23:33:57] <Wolf__> mesa sells a thingy to do that
[23:34:10] <Wolf__> or you can diy one
[23:34:14] <Tom_L> unless the ground is floating like it is on mine
[23:34:15] <RyanS> and I guess the speed sensor too?

[23:35:07] <Tom_L> that's the only purpose for that board on the left
[23:35:10] <Tom_L> isolation
[23:37:01] <Wolf__> https://mesaus.com
[23:37:05] <RyanS> the speed control is bottom left on the box https://www.machines4u.com.au
[23:38:03] <Wolf__> I think with the Spinx1 you need to add your own spindle feedback
[23:38:20] <RyanS> could probably just put a connector in place of the pot
[23:38:45] <Wolf__> thats what I just linked, the mesa spinx1
[23:39:46] <Tom_L> i've got a separate encoder on my spindle anyway
[23:40:15] <RyanS> what's the specs on the transformer psu?
[23:40:16] <Wolf__> err I read that wrong, but need to make sure the control systems dont cause ground loops to each other, that makes for bad day™
[23:40:53] <Tom_L> RyanS, mine?
[23:41:14] <RyanS> yeah
[23:41:34] <Tom_L> surplus stuff i put together but ~48v 18A
[23:41:48] <Tom_L> a little overkill
[23:41:58] <Tom_L> i could probably get by with one of those transformers
[23:42:15] <RyanS> any difference between a toroidal and that style?
[23:42:26] <Tom_L> these were cheap :)
[23:42:41] <Tom_L> toroid is probably more efficient
[23:43:14] <Tom_L> caps were surplus too or i'd have one big one
[23:45:33] -!- mozmck_lp has joined #linuxcnc
[23:46:17] <RyanS> and the secondary voltage of the transformer is about 30V? i think I read the formula is secondary * 1.4?
[23:47:37] <Wolf__> https://www.ebay.com damn thats cheap
[23:49:21] <Wolf__> maybe I should stick one on my 12x37 lathe seeing last owner had put a 1/3hp on it
[23:50:53] <Tom_L> it may have been a little more than that, i can't honestly remember now
[23:55:19] <Tom_L> Wolf__, what's the black thing above the motor?
[23:56:56] <Wolf__> its a indexer for the controller, so when you let off the pedal the sewing machine spindle aways stops w/ the needle down
[23:59:22] <RyanS> do you know if the VA rating can be directly converted to DC watts with ohms law? I think VA is just power in the context of AC
