[00:00:35] <enleth> yeah, too many cuts, too hammy
[00:00:40] <enleth> *way* too hammy
[00:01:24] <_unreal_> enleth, are you talking about a big one for something like a rotory or a lathe?
[00:02:06] <enleth> _unreal_: all of them - handheld drills, corded and cordless, drill press chucks, lathe tailstock chucks
[00:02:08] <roycroft> use collets :)
[00:02:22] <enleth> I've had all of those stuck at some point
[00:03:42] <_unreal_> any thing that has multi moving parts is likely to bind
[00:03:46] <_unreal_> at some point in time
[00:03:59] <enleth> I'm really starting to think they should all at the very least come with flats ground/cut on both the rotating shell and the base, so that if it comes to the worst, you could take two large wrenches and fix it
[00:04:03] <enleth> but no, it's just knurled
[00:04:10] <enleth> or ribbed if it's plastic, or whatever
[00:04:54] <enleth> and then it's strap wrench time, or vise grips with some scrap rubber/leather
[00:05:35] <enleth> or whacking the drill on the side with a hammer, works sometimes
[00:05:40] <enleth> I mean, the drill bit
[00:13:25] <roycroft> i do the vice grips/channel locks with a strip of leather thing upon occasion
[00:13:42] <roycroft> but i do leatherwork, so i always have bits of leather laying around
[00:19:52] -!- logs has joined #linuxcnc
[00:27:19] <enleth> I just did that to get a drill bit out of my corded drill
[00:28:13] <XXCoder> enleth: indeed!

[03:10:27] <gloops> https://www.youtube.com interesting variation of 4th axis on router
[03:13:47] <XXCoder> yah
[03:13:55] <Deejay> hehe cool
[03:14:04] <XXCoder> looks 3d printed
[03:14:32] <gloops> yeah theyll all be making them
[03:16:51] <MarcelineVQ> up until the teeth fill up with chips
[03:17:09] <gloops> r&p wont be very accurate for the rotary, maybe good enough for wood though
[03:19:47] <CaptHindsight> two third axes to be anal
[03:23:21] <gloops> when i do mine, im not having it on the main router table, ive got an old quality wood lathe, so i plan on having it as a 4 axis router, but also available for manual turning when i want
[03:24:35] <gloops> if the spindle/z axis travels above it wont be in the way at all for manual work

[03:52:06] <miss0r> Mornin'
[03:52:32] <XXCoder> yo
[03:53:52] * miss0r is about to design and build a floating tapping head for the cnc
[03:54:01] <XXCoder> nice
[03:54:57] <miss0r> perhaps it will be :)
[03:55:05] * miss0r is just brainstorming at the moment
[03:58:12] -!- JesusAlos has joined #linuxcnc
[04:08:51] <miss0r> its occuring to me that this is one of those builds that will take days to complete, if I end up going abe shit about it. Grinding everything ect...
[04:08:55] <miss0r> and I might just do that :D
[04:11:40] <gloops> note from daughter seems to have put paid to my plans today - shes home from uni doing some part time work at the local wetherspoons 'dont make any noise tommorrow didnt get in while late need a long lie in' ffs

[04:23:59] <miss0r> bah! Looking for some wire to use for my mesa build. I'm thinking 0.35mm^2.. but it would seem that is roughly 10x as expensive as 0.5mm wire...
[04:24:18] <miss0r> (yeah, I didn't realy muster the motivation to get started on the floating head build) :D

[04:49:29] <XXCoder> miss0r: nike said it right
[04:58:41] <miss0r> yup
[04:59:18] <XXCoder> man some days I really miss being able to see stars
[05:00:19] <XXCoder> BIG downside to cities is light pollution
[05:00:23] <miss0r> yeah
[05:00:35] <miss0r> I live on the border of farmland, I can see stars :)
[05:00:54] <miss0r> well.. not right now, as it is 11:00
[05:00:54] <XXCoder> it would take me 2 hour drive minium to go to maganate 2 darkness
[05:01:05] <XXCoder> thats minium to see milky way
[05:01:13] <miss0r> damn
[05:01:17] <miss0r> I'd get crazy
[05:01:33] <XXCoder> http://www.jshine.net
[05:02:09] <XXCoder> east side got it worse
[05:02:33] <miss0r> Sadly, this does not work outside of the US
[05:02:59] <XXCoder> yeah too bad the dark sky finder dont have anyone doing any work outside usa
[05:03:34] <XXCoder> 2 hours 14 min for one route to darkest sky
[05:04:52] <miss0r> yeah
[05:05:11] <XXCoder> it covers canada and mexico
[05:05:21] <miss0r> Would any of you know if it is possible to use one of those generic USB cnc controllers(sold for use with Mach3) with linux cnc?
[05:05:53] <XXCoder> theres few pins for darkness but map isnt showung night chart
[05:06:01] <XXCoder> what country you in?
[05:06:08] <miss0r> Denmark
[05:06:22] <XXCoder> theres 2 pins there
[05:06:42] <XXCoder> muldbjerg and unnamed site 5558
[05:07:28] <XXCoder> unnamed is at odense
[05:08:07] <miss0r> When looking at a light pollution map of Denmark, it does not look at that good where I live, actualy :)
[05:08:28] <XXCoder> does it say what magagate light your places at?
[05:08:52] <XXCoder> https://sfct.org
[05:09:06] <XXCoder> mines at 8-7 depends where I am in tacoma
[05:09:24] <XXCoder> at vancouver I used to have 6
[05:09:56] <miss0r> ahh the bortle value.. I saw that somewhere, hang on
[05:10:13] <miss0r> 2.7
[05:10:41] <miss0r> so somewhere between average dark sky and rural
[05:10:41] <XXCoder> someday I will have vacation to see 1 level site. timing is HARD because clouds could happen
[05:10:55] <miss0r> yeah
[05:11:19] <MarcelineVQ> shucks buster, take the chance out of it, save up for a space launch
[05:11:40] <XXCoder> lol that'd be basically 0 light level
[05:11:52] <XXCoder> zero light pollution, zero sky inference
[05:11:56] <miss0r> yeah, no "chance" involved in traveling to space
[05:12:09] <MarcelineVQ> no chance of cloudy weather
[05:12:11] <XXCoder> there is a VASTLY cheaper way though
[05:12:15] <XXCoder> plane.
[05:12:25] <XXCoder> charted not commerical
[05:12:45] <XXCoder> just couple hours flight off coast into very dark ocean skies, above clouds
[05:13:00] <XXCoder> sky is thinner also
[05:13:14] <miss0r> We used to do miletary exercises in a place that is level 1
[05:13:22] <miss0r> that place was DARK at night :)
[05:13:43] <XXCoder> if I was made from money, I would create a clear top plane, limited seating plenty of spaces to walk around and chat
[05:14:08] <XXCoder> it'd be large commerical plane, converted so it could fly for hours. parties!
[05:14:57] <XXCoder> large kitchen, space to chat and stare at skies, and full size restrooms. none of those barely fit in crap
[05:15:11] <miss0r> but the quite kind, about looking at the sky, not playing beer bong
[05:15:12] <XXCoder> more leg space than president plane
[05:16:19] <XXCoder> indeed
[05:16:39] <XXCoder> only flaw is skywatcher party plane would cost quite a bit
[05:16:48] <XXCoder> probably double or more than regular plane cost
[05:17:09] <MarcelineVQ> If money isn't a barrier I'd make a tower into space and stand on top of the planet, alone but for the endless life below
[05:17:37] <MarcelineVQ> trace my fingers around and pretend I'm swiriling the hurricanes
[05:17:42] <XXCoder> marc there is conceptal tower design that bypasses physics limition of materal
[05:18:24] <XXCoder> its dynimatic structural support tower, basicallt it uses impacts from base to keep upwards, using tubes and such
[05:18:41] <XXCoder> makes tower MUCH more stiff than any mere mortal mineral building can be
[05:19:38] <miss0r> You gotta love science
[05:19:39] <XXCoder> theres also concept using similiar idea to build launcher arc, thats miles high and crosses many miles
[05:20:05] <XXCoder> it uses water or any media being pumped very very fast so momenium prevents structure from falling
[05:20:44] <MarcelineVQ> these sound like amazing ideas for making videos of spectacular momentary failures
[05:20:55] <XXCoder> yeah
[05:21:18] <miss0r> yeah.. "what does this button do"
[05:21:23] <XXCoder> there is another one, one of later structures, its a ring around entire world. it does NOT rotate so people can walk on it
[05:21:32] <XXCoder> 80% gravity at that distance from earth
[05:21:46] <XXCoder> it uses 2 spinning very thick cables to keep up
[05:21:52] <XXCoder> one is spinning other way
[05:22:26] <XXCoder> so such structure can simply launch something by pushing it to orbial speeds
[05:22:34] <MarcelineVQ> so it does rotate, it just rotates with the earth?
[05:22:43] <XXCoder> it cant simply drop it as it would fall into earth lol
[05:23:02] <XXCoder> yeah, if it didnt have dynimatic support it would fall into earth
[05:23:09] <MarcelineVQ> Yes it would
[05:23:41] <MarcelineVQ> even then it probably would, given how good humans tend to be overall at engineering :>
[05:23:47] <XXCoder> 2 thick cables spinning, and use magnets to keep it up to speed it should last forever since it has no physical contact
[05:23:58] <XXCoder> solar panels to keep it powered forever
[05:24:07] <MarcelineVQ> no contact? not sure what you're talking about with cables
[05:24:19] <XXCoder> quite good most times, we can miss some details though
[05:24:28] <XXCoder> MarcelineVQ: basically picture it this way
[05:25:03] <XXCoder> its a pair of tubes, with coverings and cable going all way around earth
[05:25:29] <XXCoder> ignoring any extra structure such as fuel depots, humans homes work spaces etc, that bare sturcture is all we need for this example
[05:25:30] <MarcelineVQ> it's the cable part I'm unclear about
[05:25:49] <XXCoder> cable is held in place inside tube by magnets that can also spin cable up
[05:26:15] <XXCoder> so when its spinning fast enough, tube can't change shape as long as tube ingeration is intact
[05:26:28] <XXCoder> so it stays rigid tube
[05:27:08] <XXCoder> gyro also means it can't change angle
[05:27:47] <XXCoder> we could opt out of that and use water as spinning media, so its like hose going all way around world
[05:28:02] <XXCoder> water is moving really fast so hose cant kink or move
[05:29:19] <XXCoder> of course spinning one would cause tube to move opposite direction
[05:29:26] <XXCoder> so theres another going other way
[05:29:41] <XXCoder> bingo, it stays on place and 2 tubes mean its nice and super rigid
[05:32:50] <XXCoder> MarcelineVQ: https://www.youtube.com
[05:33:43] <XXCoder> less cluttered one https://www.youtube.com you see the two tubes.
[05:35:34] <XXCoder> the structure to earth have two uses, making ring stay in center, and bringing up and down stuff
[05:36:22] <MarcelineVQ> Yes it would need such a structure. an orbital ring like you're describing that uses gyroscopic action is free to move along the axis tangent to the disk it describes, in other words without orbital tethers like the ones with elevators in that vid it can just slide away from the planet never to be seen again
[05:36:53] <XXCoder> yeah I guess it would need to be built offsite first
[05:37:12] <MarcelineVQ> It will also need a whole of of motors along its entire outside for small corrections of the stucture over time
[05:37:13] <XXCoder> then lowered into earth then tethered while its in active centering
[05:37:18] <MarcelineVQ> *whole lot
[05:40:04] <MarcelineVQ> The most interesting form of this sort of superstructure to me is the ringworld, though a lot of people really like dyson spheres since they don't waste any solar energy. ribbons around suns are cuter than balls
[05:42:06] <XXCoder> you should watch more issac autur videos
[05:42:12] <XXCoder> great possibiltes
[05:42:33] <XXCoder> we could do "dyson sphere" which really is billions of space habs around sun
[05:45:31] <jthornton> morning
[05:47:23] <XXCoder> HexaCube: yo
[05:48:48] <XXCoder> hows your research going HexaCube
[05:49:35] <HexaCube> slow :P
[05:49:43] <HexaCube> still looking for a stepper driver i like :D
[05:50:04] <XXCoder> cool :)
[05:50:29] <jthornton> what voltage?
[05:51:10] <HexaCube> 36V or less
[05:51:18] <HexaCube> I really really like the trinamic stepper drivers because of their features
[05:51:32] <HexaCube> but they don't offer quite enough voltage (2.2A and the motor is specced for 2.8A)
[05:51:35] <HexaCube> erm
[05:51:41] <HexaCube> current, not voltage
[05:51:46] * HexaCube still a bit drunk
[05:52:39] <jthornton> this is the best drive out there for 50v or less https://www.geckodrive.com
[05:53:43] <HexaCube> why, if I may ask?
[05:53:52] <XXCoder> as low as $39 but I sont see how
[05:54:00] <HexaCube> Trinamics are well known for 3d printers, but that's a somewhat different use case, I guess
[05:54:09] <jthornton> I don't see $39 either
[05:54:18] <XXCoder> $65.00 As low as $39.00
[05:55:01] <jthornton> the gecko drives are bullet proof and they morph from 10 micro steps to full steps as the rpm increases so best performance and least vibration
[05:55:03] <miss0r> In my opinion you can get away with a wide vareity of drivers.. as long as you have a proper controller
[05:55:07] <MarcelineVQ> gecko's can take a lot of abuse
[05:55:26] <miss0r> but that being said, I like gecko :)
[05:55:41] <MarcelineVQ> those are actually cheaper than the last ones I saw too
[05:56:13] <jthornton> they are a bit higher in price but if you don't want to putz around with drives they are the way to go
[05:56:35] <miss0r> yeah, they are basically guaranteed to do thy bidding
[05:56:38] <jthornton> that's the 50v one without a case but has terminals and heat sink
[05:56:54] -!- syyl has joined #linuxcnc
[05:57:31] <miss0r> bah.. .I'm required to go socialize... see you around
[05:57:32] <HexaCube> jthornton: I don't mind tinkering with drivers to be quite fair. The TMC drivers have up to 256x microstepping, which is quite cool
[05:57:37] <HexaCube> aswell as some other *REALLY* nice features
[05:57:48] <HexaCube> like adjusting motor speed to prevent a stall, detecting a stall
[05:58:07] * jthornton wonders where the microstepping myth page was
[05:58:26] <HexaCube> jthornton: I'm aware about that, but it makes the motors whisper quiet and run very smooth
[05:58:44] <HexaCube> for a router quiet motors aren't really important, to be fair :P
[05:58:55] -!- asdfasd has joined #linuxcnc
[05:59:41] <jthornton> The real compromise is that as you increase the number of microsteps per full step, the incremental torque per microstep drops off drastically. Resolution increases but accuracy actually suffers.
[06:01:42] <HexaCube> Right, something like that I do remember reading

[06:04:25] <XXCoder> it doesnt matter for 3d printers up to a point, but milling it matters a whole lot more
[06:04:28] <XXCoder> much more sideload and such
[06:05:26] <HexaCube> so I'd actually wanna run with very little microstepping?
[06:05:41] <XXCoder> no like anything theres a balance
[06:05:50] <HexaCube> fair enough, I understand
[06:06:02] <XXCoder> I dont know enough to give more specifics but others here do
[06:06:18] <XXCoder> my machine I use 8x which seems to work very well when I was cutting wood.
[06:06:51] <XXCoder> also, I dont care if it sounds like its crunching gravels as long as machine is fine and neighbors dont hear it
[06:06:58] <jthornton> that's one of the many reasons gecko is a great drive it has 10 micro steps at slow speed and morphs to full steps as the speed increases and the morph point is adjustable
[06:07:21] <XXCoder> dynimatic microstepping is great way to preserve torque strength yeah
[06:07:38] <XXCoder> also, 10? odd because thats not power of 2
[06:07:40] <jthornton> and my steppers run very quiet
[06:09:54] -!- MatrixTravelerbo has joined #linuxcnc
[06:10:57] <HexaCube> jthornton: hmm, why not just stick with 10 micro steps, permanently? Can the serial port not keep up otherwise?
[06:11:36] <XXCoder> in other words, permently low torque?
[06:11:45] <jthornton> no it's about having the best torque at full speed the input pulse is 10 microsteps all the time
[06:12:34] <jthornton> also the morph point is set so the stepper does not make the rattling noise as it crosses some electrical thing
[06:13:56] <HexaCube> jthornton: but see how quit those motors are? :P https://www.youtube.com
[06:14:01] <HexaCube> quiet*
[06:16:29] <MarcelineVQ> Kinda had to say, person filming didn't make a control sound at the start for comparison
[06:16:43] <MarcelineVQ> *hard to say
[06:17:20] * jthornton thinks 95% of putube videos are crap
[06:17:35] <HexaCube> https://www.youtube.com
[06:17:50] <XXCoder> 90% of anything is crap
[06:18:01] <HexaCube> comparison to the go-to drivers before the Trinamics became popular :P

[06:22:00] <HexaCube> but to use the TMCs with the properly sized motors I'd have to make my own drivers essentially
[06:22:06] <HexaCube> and that's complicated :C
[06:22:22] <MarcelineVQ> Or not be concerned about noise
[06:22:33] <HexaCube> well, price is my main concern ;P
[06:22:53] <jthornton> only 12h:58m:58s of daylight today so the chickens get 1h 2m of extra light
[06:23:33] <MarcelineVQ> Don't agonize too much, the drivers were the cheapest part of my build by far, it's worth it to spend a bit on them
[06:23:36] <jthornton> if price is the reason then just get the cheapest one you can find
[06:23:43] <MarcelineVQ> I probably spent as much on fasteners as drivers :X
[06:23:50] <HexaCube> https://www.trinamic.com
[06:24:18] <HexaCube> that's the IC I'd have to use for nice drivers but... nyeh, I never did any 4 layer board design yada yada yada
[06:24:37] <MarcelineVQ> If ur gonna make it from scratch you might as well make a dc servo anyway
[06:24:59] <MarcelineVQ> No sense making a stepper from components with all the ready-made options
[06:25:25] <MarcelineVQ> or servo for that matter hehe, but if you've the choice to make one or the other..
[06:28:06] <HexaCube> well it does make sense if it ends up being cheaper
[06:28:25] <HexaCube> which is quite a possibility, seeing how the Geckos cost 50-60USD each for instance
[06:28:36] <MarcelineVQ> Value your time HexaCube
[06:28:37] <HexaCube> but... it'd be a whole new project
[06:28:45] <HexaCube> eh I have pleeenty time ;P
[06:29:13] <MarcelineVQ> Even if your time was valued at 10$ an hour it's not worth it to make your own geko
[06:30:03] <HexaCube> I wish my time was worth that much :P
[06:30:10] <HexaCube> that'd be more than what I get at work hourly
[06:30:16] <MarcelineVQ> It is, whether you make that or not
[06:30:59] <jthornton> and the lights come on and the coop door opens as if by magic :)
[06:31:03] <HexaCube> who says it is? :P
[06:31:18] <HexaCube> i mean, I don't see how free time is worth anything really
[06:33:19] <Tom_L> morning
[06:34:06] <jthornton> morning
[06:36:14] <Tom_L> is 'run from line' in the docs somewhere?
[06:38:05] <XXCoder> hey
[06:38:40] <jthornton> in the Axis docs yes
[06:38:55] <jthornton> what were you talking about the other day about run from line?
[06:38:57] <Tom_L> i just found it mentioned there
[06:39:20] <Tom_L> do you know when it was introduced to lcnc?
[06:39:27] <Tom_L> or has it been there all along
[06:39:32] <jthornton> a long time ago
[06:39:52] <MarcelineVQ> it is mentioned, though the easier way to use it doesn't seem to be mentioned. which is to right click on the line you want to run and click run from line there
[06:40:09] <Tom_L> i ran across it by accident is why i wondered if it was in the docs
[06:40:46] <Tom_L> i thought it was somewhat new, maybe introduced around the time the new TP was added
[06:40:47] <jthornton> http://linuxcnc.org
[06:40:59] <jthornton> 1.3.1.14 Set next line
[06:41:22] <jthornton> at least since 2.2
[06:41:38] <Tom_L> wow
[06:41:59] <Tom_L> i never new it was there until lately
[06:42:33] <Tom_L> do the other GUI support it?
[06:42:51] <jthornton> dunno

[07:48:22] <valentin_s> hey, would it be possible to control my huanyang vfd by the rs485 from my 7i96 mesa card directly?
[07:49:05] -!- valentin_s has quit [Read error: Connection reset by peer]
[07:54:39] <jthornton> how are you making the configuration for your 7i96?
[07:54:44] <jthornton> just wondering
[07:55:35] <jthornton> The 7I96 has one RS-422/RS-485 interface available on TB2. This interface is
[07:55:35] <jthornton> intended for I/O expansion with Mesa SSERIAL devices.
[07:55:50] <jthornton> then I see this: For 2 wire RS-485 applications, TX+ must be connected to RX+ and TX- must be
[07:55:50] <jthornton> connected to RX-.
[07:57:01] <jthornton> anyway when pcw_home wakes up he can answer that

[09:50:43] -!- Motioncontrol has quit [Client Quit]
[09:52:25] <pink_vampire> you need to run the coolant through enough chips to filter the smell out

[10:49:15] <fragalot> The alcohol seems to have taken the edge off of the stink. ( I did not actually light it :P)
[10:49:51] <fragalot> I also just made my first cuts. Really impressed so far!
[10:51:17] <fragalot> Hogs pretty well considering the size and power available, and the surface looks fantastic with a nice overlapping cross hatch pattern in both x and y

[10:57:28] -!- fragalot has quit [Ping timeout: 252 seconds]
[10:59:36] <pink_vampire> is that the coolant for the catting or for the spindle?
[11:00:40] <HexaCube> why not both :P

[11:12:17] <fragalot_> Ffs, cutting
[11:13:28] <pink_vampire> try to keep the system close
[11:13:39] <HexaCube> I think our spindles actually are cooled with cutting coolant
[11:13:42] <fragalot_> It's behind a transformer so the leakage current must be quite high, should be easy to find
[11:13:47] <HexaCube> the coolant is cooled, too
[11:14:22] <fragalot_> This spindle is cooled by sheer mass :)

[14:59:50] <syyl_> finaly got the t&c grinder all back together and in a condition that i want it to be :D
[14:59:51] <syyl_> http://gtwr.de
[15:00:08] <infornography> ello, I connected a hobbycnc EZ to a pc last night and had some issues with missed steps and sometimes the motor would spin in reverse. I maxed out timing settings and it didn't seem to have much effect. I'm thinking about trying a shorted parallel cable..
[15:00:15] <syyl_> time to scrap some tools in the process of learning how to sharpen them ;)
[15:00:21] <fragalot> syyl_: looking good :D
[15:00:51] <gloops> very nice syyl
[15:01:00] <infornography> thats clean
[15:01:18] <gloops> some purists would argue that you should never have tried to remove the priceless patina
[15:01:30] <fragalot> syyl_: does it have any wear in it at all?
[15:01:36] <gloops> but it looks very nice
[15:01:40] <syyl_> no, its unused since built in 1999 :D
[15:01:41] <fragalot> gloops: it doesn't look like he removed any patina
[15:01:53] <syyl_> but it was basicaly a kit to be finished by the owner ;)
[15:01:58] <syyl_> chineseium
[15:02:06] <fragalot> I see
[15:02:27] <fragalot> nothing wrong with chinesium kits :-)
[15:02:41] <syyl_> for example the bellows on the vertical axis. there where none - all the grit from grinding would wear the column right away
[15:02:48] <gloops> right - i guess i was just flagging up the need to preserve patina on old machines, where it applies
[15:03:01] <syyl_> :)
[15:04:01] <fragalot> I need to replace the wipers on my mill
[15:04:16] <fragalot> currently they appear to be soft neoprene, about 15mm thick
[15:04:26] <fragalot> well, it USED to be soft, now half of it is glass hard
[15:04:37] <gloops> soft is better than brittle..no?
[15:04:37] <syyl_> and thats what cooleant does with rubbery materials :D
[15:04:39] <fragalot> does regular felt work, or does this have to be something more fancy
[15:04:48] <syyl_> natural felt
[15:05:10] <syyl_> be sure to get proper natural one, not the arts-craft-store stuff, that can have abrasive shit in it

[15:07:26] <syyl_> uhm
[15:07:32] <syyl_> wow :D
[15:07:48] <syyl_> that stuff i got from a local felt place is very firm
[15:08:05] <fragalot> compressed it is
[15:09:17] <fragalot> hm, seems all the ebay felt is either super loose or has adhesive pre-applied >.>
[15:09:25] <syyl_> hmm
[15:09:38] <syyl_> i think you could use a hard felt polishing pad
[15:09:56] <syyl_> if they are large enough
[15:10:16] <fragalot> the wiper on the Z axis is about 220mm wide
[15:10:21] <syyl_> ops

[15:44:00] <XXCoder> so much lower chance of leaving eh
[15:45:24] <gloops> no, much lower chance of remaining
[15:45:39] <pink_vampire> what could possibly go wrong - offsets, clamping, fixturing https://www.youtube.com
[15:45:59] <XXCoder> ah. your statement have ambiguity in it thats why its confusing.
[15:46:42] <XXCoder> first one: failure to dry run first
[15:47:34] <pink_vampire> XXCoder: offset the z wrong
[15:47:53] <XXCoder> yeah dry run would expose that without breaking anything
[15:48:14] <XXCoder> third is programming error, not set safety z height high enough
[15:48:47] <pink_vampire> i think i was -+ issue
[15:49:38] <XXCoder> so many of em doesnt even walk in! jeez!
[15:50:13] <XXCoder> unproven program, unproven setup, always walk in in very least
[15:51:35] <XXCoder> the one with nut is why I like Z rise first then XY movement
[15:52:23] <XXCoder> last one yeah fixture setup problem lol
[15:53:01] <pink_vampire> i like the simulation in HSM
[15:53:23] <XXCoder> isnt it also show tool and head so it would show if any issues?
[15:54:43] <pink_vampire> it can do full machine simulation
[15:55:21] <XXCoder> nice! though even if you checked it over in sim, always walk first part after setup, because everyone makes mistakes.
[15:55:35] <XXCoder> https://www.youtube.com second one EWWW hand is NEVER a good clamp!
[15:55:57] <XXCoder> (no hurt besides burn from sheer stupidity)
[15:56:10] <syyl_> haha pink_vampire, 1:15 is always great
[15:56:19] <syyl_> that machine will not be happy after the crash

[15:57:05] <gloops> who hasnt done that
[15:57:22] <syyl_> i crashed a bunch of tools in the datron at work
[15:57:25] <syyl_> with a 40k spindle
[15:57:36] <XXCoder> I crashed only once
[15:57:41] <pink_vampire> gloops: this is why we have cnc
[15:57:43] <syyl_> but nothing that massive
[15:57:50] <XXCoder> I destroyed $1,00 chuck collet cat50
[15:57:54] <fragalot> I've crashed a machine running batch parts all day
[15:58:06] <fragalot> suddenly the toolchanger decided that the 50mm drill wasn't what it wanted
[15:58:12] <fragalot> so it tried to drill with the haimer
[15:58:16] <pink_vampire> I hope not crushing any thing
[15:58:29] <syyl_> most of the time the axis go into over-current bevor anything major looses its shit
[15:59:00] <syyl_> ouch, fragalot
[15:59:05] <fragalot> also had a barfeeder go wrong overnight
[15:59:17] <XXCoder> fragalot: dang
[15:59:28] <fragalot> fun times :-)
[15:59:29] <syyl_> i will never forget how the dmg 50v decided to drop the renishaw in front of the toolchanger :D
[15:59:31] <pink_vampire> the only fail as set Z10 instead of offset it to 0, aand it mark the vise jaw
[15:59:32] <syyl_> *plock*
[15:59:37] <fragalot> syyl_: xD
[15:59:39] <XXCoder> fragalot: thats expensive lol
[16:00:05] <fragalot> XXCoder: yes it was, barfeeder was scrapped
[16:00:16] <fragalot> and the lathe needed new bearings
[16:00:54] * fragalot is looking at toe jacks
[16:00:57] <fragalot> any recommendations?
[16:01:02] <syyl_> or the shitty eberle cnc router that decided to break its own toolchanger
[16:01:03] <syyl_> http://gtwr.de
[16:01:20] <syyl_> http://gtwr.de
[16:01:34] <syyl_> needed a bit of rebuilding ;)
[16:01:37] <fragalot> haha
[16:01:37] <pink_vampire> syyl_: BUT WHO??
[16:01:47] <syyl_> that was a controller-glitch
[16:02:07] <pink_vampire> it was linux cnc?
[16:02:11] <syyl_> nope
[16:02:22] <pink_vampire> than fine.
[16:02:26] <syyl_> a windows based retrofit
[16:02:32] <syyl_> by a company called "knotenpunkt"
[16:02:33] <fragalot> ha. windows
[16:02:51] <pink_vampire> I'm lazy
[16:02:59] <fragalot> windows is probably one of the worst choices for realtime
[16:02:59] <pink_vampire> I need help
[16:03:01] <syyl_> http://gtwr.de
[16:03:27] <fragalot> syyl_: I like the percussive maintenance claw hammer in the back
[16:03:29] <syyl_> after straightending the pneumatic cylinder and reballing the linear guide it kinda worked until i got spare parts :D
[16:04:06] <syyl_> oh thats a non-marring hammer
[16:04:32] <fragalot> it's got the exact same handle as my (ancient) claw hammers
[16:04:36] <XXCoder> syyl_: ow
[16:04:36] <syyl_> :D
[16:05:11] <syyl_> the machine itself was very nice
[16:05:11] <syyl_> http://gtwr.de
[16:05:29] <XXCoder> pink_vampire: you actually do stuff, which is way more thjn I do lol
[16:05:40] <syyl_> all cast iron construction, 400W yaskawa servos, ibag spindle
[16:06:30] <pink_vampire> what is the max size tool diameter you can use in the ibag?
[16:06:39] <syyl_> largest was a 10mm collet
[16:06:49] <syyl_> took #20 taper tooling
[16:06:59] <pink_vampire> I'm limited to 1/4" :(
[16:07:14] <syyl_> with 6mm tooling the machine could fly
[16:07:23] <pink_vampire> the the torque on the HF is not grate..
[16:07:24] <syyl_> 10mm was a bit much for it
[16:07:42] <syyl_> but hardmilling steel, with a 6mm endmill worked brilliant
[16:08:09] <pink_vampire> also here. hard mill is nice. but I love PVC
[16:08:30] <pink_vampire> the fact that yu can glue is and use it so fast
[16:08:36] <pink_vampire> you*
[16:10:15] <pink_vampire> are you using any tools like face mill / fly cutters?
[16:10:23] <syyl_> not in the router
[16:10:42] <syyl_> i own and use a facemill for my manual mill
[16:10:50] <fragalot> fly cutter going 40k rpm would be interesting
[16:11:04] <syyl_> there are small facemills for that purpose
[16:11:06] <pink_vampire> fragalot: LOLL
[16:11:07] <fragalot> i've got a facemill, but still use a flycutter sometimes just for cosmetic purposes
[16:11:16] <fragalot> the facemill is GREAT though
[16:11:23] <fragalot> it's super economical in terms of inserts
[16:11:26] <syyl_> i used a small round-insert cutter in the datron
[16:11:28] <fragalot> as it only ever wears out 1 at a time
[16:11:33] <XXCoder> yeah theres quite small facemills
[16:11:37] <syyl_> 16mm diameter
[16:11:38] <XXCoder> its great for certain uses
[16:11:49] <syyl_> worked brilliant for steel
[16:12:05] <XXCoder> sjmallest I have used is one inch but im sure there is smaller
[16:12:16] <syyl_> they go down to 8..10mm
[16:12:24] <syyl_> havent seen them smaller

[16:13:37] -!- flyback has quit [Quit: Leaving]
[16:13:41] <pink_vampire> you can use stuff larger then the collet size, and you can go to a torque issue
[16:13:50] <pink_vampire> but unbalanced cutter on HF spindle = russian roulette
[16:13:55] <fragalot> y'know what. I was planning to get my own toe jack & machine rollers to shift things around
[16:14:06] <syyl_> and, already ordered?
[16:14:13] <fragalot> but now that i've actually found a place to get them from, and the pricing... I think I'll just continue borrowing them :D
[16:14:44] <syyl_> haha :D
[16:15:41] <pink_vampire> toe jack on wooden floor would be interesting
[16:15:55] <fragalot> no it wouldn't
[16:16:21] <pink_vampire> it will crack the floor
[16:16:31] <fragalot> which isn't interesting, just poor planning :D
[16:17:14] <Wolf__> breaking floor joists is always great
[16:21:48] <Wolf__> johnson bar might be better for small shop vs toe jack
[16:22:09] <fragalot> yes and no
[16:22:19] <fragalot> problem with those is that they don't reach high enough to get it off of the blocking it's on now
[16:22:23] <Wolf__> if you have room lol
[16:22:31] <fragalot> that too
[16:22:57] <fragalot> I've decided that it's kinda like a van
[16:23:12] <fragalot> it's better to have a nice friend that lets you borrow his than it is to have your own :D
[16:23:21] <Wolf__> lol
[16:24:26] <Wolf__> could stack up wood to get the height needed to lift it and work the machine down little at a time
[16:25:23] <fragalot> true, I could do that with the big crowbar too probably
[16:26:48] <fragalot> not much to grab on to casting wise on the schaublin though
[16:26:59] <Tom_L> fragalot why you raisin rodents in your coolant anyway?
[16:27:13] <fragalot> Tom_L: was as-delivered :P
[16:27:18] <Tom_L> ahh
[16:27:22] <fragalot> I thought they were globs of grease at first
[16:27:23] <Tom_L> wonderful
[16:27:26] <fragalot> until I noticed little tails
[16:27:27] <fragalot> and legs
[16:27:29] <Tom_L> heh
[16:27:41] <fragalot> and then a bigger tail
[16:27:46] <fragalot> smelled awful.
[16:29:37] <fragalot> the return line wasn't hooked up, so i'm guessing they crawled in and couldn't get out again

[16:57:11] <XXCoder> cool

[21:21:39] <pink_vampire> piltier for laser???
[21:21:50] <XXCoder> noit going to happen lol
[21:22:24] <pink_vampire> it is a diode?
[21:23:35] <XXCoder> nah co2 like i said. Roguish linked that to wolf by mistake its unreal that needed smaller scale cooling
[21:30:39] -!- veek has joined #linuxcnc
[21:35:01] <Wolf__> I was planning a water chiller made from a old dehumidifier for a 120W co2 laser
[21:35:45] <pink_vampire> like the dehumidifier for 50$ from walmart???
[21:36:02] <Wolf__> no, like $5 yard sale
[21:36:49] <pink_vampire> I never thought that you can cool something with it.
[21:37:08] <Wolf__> its a freon compressor inside
[21:38:56] <pink_vampire> i need to lower the temp of the spindle coolant
[21:39:04] <XXCoder> yeah it works by cooling air so water gets out
[21:39:10] <XXCoder> so not surpised
[21:39:20] <XXCoder> theres other way, compressor type
[21:39:30] <XXCoder> he dont need that though as it dont actually cool air
[21:40:22] <Wolf__> well, inside the dehumidifier is the same innards as a window ac unit
[21:42:01] <Wolf__> only difference is its all in one line in the air path, high and low side coils
[21:51:40] <pink_vampire> small office fridge
[21:51:53] <Wolf__> same innards as well
[21:52:18] <_unreal_> I'm looking at options for cooling my tinker board
[21:52:34] <pink_vampire> but it is much easyer to put a bucket inside
[21:53:00] <Wolf__> dehumidifier is quicker to use to add a 240mm x 120mm radiator in to the mix behind the condenser coil
[21:53:28] <Wolf__> one thing about machine cooling is you need to keep the coolant above dew point of the room
[21:53:36] <pink_vampire> where do you get 240mm x 120mm radiator??
[21:53:49] <Wolf__> amazon/ebay
[21:53:55] <XXCoder> car juniyard

[21:56:37] <Wolf__> forgot shipping there
[21:56:45] <XXCoder> car junkyard.
[21:57:08] <XXCoder> people RARELY grab radiators. just find car that still has coolant and grab it
[21:57:13] <Tom_L> the ultimate in high tech cooling: http://tom-itx.no-ip.biz:81
[21:57:19] <pink_vampire> but it is 28$ + dehumidifier
[21:57:31] <XXCoder> Tom_L: very high end indeed.
[21:57:37] <Wolf__> http://a.co comes in quicker
[21:57:46] <Tom_L> it works better than i expected actually
[21:57:51] <pink_vampire> Tom_L: for DC??????
[21:58:03] <Tom_L> it's a dc motot yes
[21:58:06] <Tom_L> motor
[21:58:15] <pink_vampire> vent the motor and add a fan
[21:58:21] <XXCoder> Tom_L: you probably just need a very small mod to make it dump into radator which then dumps to tank below
[21:58:31] <pink_vampire> you just cool down the case
[21:58:35] <XXCoder> then suck from that up which has a lot more cooling power
[21:58:37] <Tom_L> this was available and cost me $0.00
[21:59:01] <pink_vampire> Tom_L: to vent it it's also 0.00$ you have a cnc...
[21:59:05] <Tom_L> i fill the bucket with ice too...
[21:59:22] <Tom_L> pink_vampire yeah but that'll let all sorts of crap in
[21:59:33] <XXCoder> ah isnt that take a bit more work than simply using radator though?
[21:59:41] <pink_vampire> on the back plate???
[22:00:35] <Wolf__> cooling the motor case is better then nothing, long as its a inductive motor
[22:01:14] <pink_vampire> Wolf__: it is dc, the case just hold the magnets
[22:01:56] <Wolf__> chat window was hiding the brush holder
[22:06:07] <Wolf__> but yes, thats why I said inductive motor...

[22:08:39] <Tom_L> https://www.ebay.com
[22:09:10] <XXCoder> pretty cheap
[22:09:17] <Wolf__> nice
[22:09:54] <Wolf__> bigger for a few buck more http://a.co
[22:12:39] <Tom_L> https://www.ebay.com
[22:12:43] <Tom_L> smaller for a few bux less
[22:13:57] <pink_vampire> Tom_L: did you put any paste?
[22:14:04] <Tom_L> no
[22:14:13] <Tom_L> i could but it works ok as it is
[22:14:42] <pink_vampire> how it is cool the coils?
[22:14:46] <Tom_L> and it would just make a big mess
[22:14:57] <Tom_L> i use ice in the bucket so nice and cool
[22:15:07] <Tom_L> and the motor lid is warm to the touch
[22:15:15] <Tom_L> after a pretty good workout
[22:16:02] <pink_vampire> hope for you the motor will last
[22:16:13] <Tom_L> i'm sure i could make it more efficient but it does the job
[22:16:29] <Tom_L> i don't push it to the limit
[22:17:54] <Tom_L> i did a ~4-6hr part a while back and it did fine
[22:19:00] <pink_vampire> that nice
[22:19:35] <Tom_L> i've got a spare motor just in case but i think it will do ok

[22:28:58] <infornography> if a chopper drive uses PWM to drive a stepper at a higher voltage, if you drive a stepper rated for the higher voltage the duty cycle should go to 100% right? *thonk*
[22:32:10] <infornography> it should act like a switch at that point by my logic, but I don't have a spare driver to burn up yet

[22:38:21] <Tom_L> that should keep you busy a while
[22:38:24] <infornography> if the motors rated amps is at the supply voltage of the driver, there would be nothing to chop
[22:38:29] <infornography> it will
[22:38:51] <Tom_L> but you have more to gain if you use a higher voltage
[22:39:36] <infornography> but I already have some 24v motors, I want to put them to use
[22:40:53] <infornography> I might try to make a simple on/off driver at some point
