[04:53:42] * SpeedEvil ponders.
[04:53:44] <SpeedEvil> http://www.ebay.co.uk/itm/Black-and-decker-bdcdmt120ia-lithium-ion-20-volt-cordless-drill-impact-combo-/111350152246?pt=Drills&hash=item19ecfc7c36
[04:53:58] <SpeedEvil> I wish small high power gearboxes were readily available
[04:55:59] <SpeedEvil> hmm. $23 as spare parts.
[05:10:15] <Swapper_> harmonic drives is not that expensive on ebay ? :)
[05:13:43] <SpeedEvil> Aren't most drills planetary, not harmonic?
[05:16:30] <Swapper_> yea think so, but they are noiser and not zero backlash
[05:16:37] <Swapper_> whats your application ?
[05:17:40] <SpeedEvil> What - I need an actual application now? :)
[05:18:24] <SpeedEvil> More seriously - I was pondering small tools on sticks for garden maintainance.
[05:18:31] <SpeedEvil> And, I know you can buy them.
[05:19:11] <SpeedEvil> I have sort-of-semi-seriously considered installing a rail system so that I can have an automated hedgetrimmer to run along it

[05:34:12] <narogon> I have a delta robot
[05:34:17] <narogon> I'm using delta kinematics
[05:34:27] <narogon> but i have some problems with soft limits
[05:34:34] <narogon> in joint mode everything is ok
[05:34:49] <narogon> but when i change to world mode
[05:35:16] <narogon> It's always says joint 0 1 2 following error
[05:36:50] <narogon> how could i debug it to find where the problem is
[05:47:40] <kengu> narogon: google not helping at all? I have no idea on your case but joint following error is pretty common,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error
[05:48:08] <kengu> https://www.google.com/search?q=joint+0+1+2+following+error
[05:48:10] <kengu> ..
[05:48:14] <narogon> when you define ferror and min_ferror
[05:48:31] <narogon> they are in machine units = joint units no???
[05:56:12] <eren_basturk> hi all, I have a question about hal compenent
[05:57:17] <eren_basturk> I have a .comp file and I installed it to under /rtlib/xenomai directory
[05:57:42] <eren_basturk> .so extension file exist under this directoy
[05:58:15] <eren_basturk> should I do more thing to use this comp file?
[06:00:00] <narogon> you make comp --install yourfile.comp
[06:00:33] <narogon> and if it is installed correctly you can load from hal
[06:01:19] <eren_basturk> yes
[06:01:25] <eren_basturk> I did it
[06:01:56] <eren_basturk> but when I run it , it doesn't load
[06:03:45] <narogon> does it says you the component doesn't exist?
[06:20:00] <eren_basturk> no no no
[06:20:09] <eren_basturk> I found the problem but i am not sure
[06:25:56] <eren_basturk> the problem is my component related with gantry
[06:26:08] <eren_basturk> i am a bit confuse
[06:26:44] <narogon> i'm not very sure what your problem is
[06:26:50] <narogon> the fact is if you make halrun
[06:26:54] <narogon> and loadrt yourcomponent
[06:27:04] <eren_basturk> it works but my probblem is
[06:27:15] <narogon> so make show
[06:27:19] <eren_basturk> ok
[06:27:19] <narogon> and you can see if it is loaded
[06:27:28] <narogon> to run in real tiem
[06:27:34] <narogon> add it to a thread
[06:27:39] <eren_basturk> It loaded but
[06:27:49] <eren_basturk> I have 3 axis CNC ini file
[06:28:05] <eren_basturk> I want to drive two motors at one axis
[06:28:15] <eren_basturk> for that reason I installed a comp
[06:28:24] <eren_basturk> but in ini file
[06:28:25] <narogon> axis are the freedom grades
[06:28:27] <narogon> of the machine
[06:28:29] <narogon> not the motors
[06:28:47] <eren_basturk> should I define one more axis for the other motor?
[06:29:03] <narogon> sorry freedom degrees'
[06:29:09] <narogon> no
[06:29:30] <eren_basturk> you mean I won't change my ini file for gantry
[06:29:35] <eren_basturk> right?
[06:31:11] <narogon> if you are using trivial kinematics
[06:31:42] <eren_basturk> yes I'm using it
[06:32:02] <narogon> X axis0 Y axis 1 Z axis 2
[06:32:02] <narogon> so if you have more than one motor to the same axis
[06:33:18] <narogon> i suppose you must link axis.n.motor-pos-cmd to 2 motors
[06:33:23] <narogon> in your hal file
[06:33:56] <eren_basturk> that is good explanation
[06:34:01] <eren_basturk> i will try it
[06:34:05] <eren_basturk> thanks a lot
[06:34:14] <narogon> axis.n.motor-pos-fb
[06:34:24] <narogon> you could only link to one of the two motors
[06:34:34] <narogon> but they are going to move exactly the same
[06:35:56] <narogon> you could control the differences between two motors position feedbacks
[06:36:27] <narogon> and check if something it's going wrong in any time
[06:39:05] <eren_basturk> thanks a lot
[06:39:16] <eren_basturk> for detailed explanation
[06:53:58] <narogon> eren_basturk there is a cinematics for your machine
[06:53:59] <narogon> gantrykins
[07:11:25] <jthornton> cinematic the art or principles of making motion pictures
[07:12:11] <jthornton> Kinematics is the study of classical mechanics which describes the motion of points
[07:12:26] * Tom_itx turns on an extra pc to take the morning chill off
[07:13:16] * jthornton notes that it is a very comfortable 66F here this morning
[07:15:13] <Tom_itx> 47°F now
[07:15:33] <Tom_itx> was a bit cooler at 3"30
[07:15:36] <Tom_itx> :
[07:24:02] <Tom_itx> seemed chilly considering the 100+ temps last week
[07:51:26] <eren_basturk> naragon it works now
[07:51:33] <eren_basturk> thanks a lot

[09:01:30] <narogon> in spanish cinematica=kinematics
[11:37:23] <gene78> hi guys, got a very small scale error.
[11:40:07] <gene78> 8x microstepping, 2/1 geardown on an x5mm screw. currently about 403, what s/b the correct scale?
[11:40:56] <jdh> 200*8*2 steps == 5mm
[11:42:02] <jdh> so 16000 pulses per mm
[11:43:45] <gene78> yeah, but at 403,xxx I am only off about 2 thou in an inch?
[11:44:39] <gene78> it is going a bit far, looks like i should reduce it
[11:45:06] <jdh> where did you get 403k?
[11:45:45] <gene78> all my dial indicators are Merican, typo, s/b a decimal point=403.3489xxxx
[11:46:22] <jdh> you lost me.
[11:46:59] <gene78> i may be running that axis nin /4 mode too., can't member
[11:47:32] <gene78> what i want there is the step to go 1mm, right?
[11:47:40] <gene78> what i want there is the steps to go 1mm, right?
[11:48:15] <jdh> acutally I multiplied instead of dividing, didn't I.
[11:49:04] <jdh> what is /4 mode?
[11:49:51] <gene78> 2m542 microstep mode, could be 4 because i ran out of speed at 8
[11:51:39] <gene78> cpu speed that is
[11:57:23] <archivist> put the machine in inch mode move an inch and see if dti agrees or move 25.4 mm
[11:57:50] <archivist> or have dual reading dti :)
[12:00:15] <archivist> moving a nats cock is difficult with microstepping so dont expect super precision
[12:02:00] <gene78> Since we can mix & match in the motion list, I am using .5inch to test with and slowly reducing the 403.xxxx so 2 taps=1 inch, fine tuning backlash by checking the center stp each direction.
[12:02:38] <archivist> to test scale do it in one direction
[12:03:03] <archivist> from outside any possible backlash
[12:03:50] <archivist> this is me testing mine
http://www.archivist.info/cnc/screw_error/
[12:04:08] <gene78> yes, given, i tst 2nd move for scale
[12:04:55] <archivist> you can see the backlash /spring wind up of mine at the beginning
[12:06:54] <IchGuckLive> hi all B)
[12:09:10] <IchGuckLive> gene78: m542 is not the fastest on stepping
[12:09:51] <IchGuckLive> best to go 400 and timingbelt or worm
[12:10:18] <IchGuckLive> best performence i got with them
[12:18:51] <IchGuckLive> Loetmichel: heavy thunder today and rain as mutch as in te 4 month bevore
[12:26:32] <gene78> I have had zero problems with a fast interface (cnc4pc C1G) and 2 usec port resets. Dir line isn't reset
[12:27:25] <IchGuckLive> that is great !
[12:35:55] <gene78> I'm going to quit on z, its within a thou in an inch, good enough for the girls I go with. Now for X, its off by /10
[12:37:04] <IchGuckLive> gene78: backlash
[12:37:36] <gene78> set zero, acts like 10 thou overcomped atm
[12:37:39] <IchGuckLive> for backlash it is good to go one full treadturn and one teeth
[12:37:56] <IchGuckLive> 10 tines check and then equaling
[12:38:52] <gene78> Turns out I hadn't zeroed it, was set .5
[12:39:25] <IchGuckLive> yeah mashine file conversions are trigy
[12:39:31] <IchGuckLive> g ,-)
[12:59:11] <IchGuckLive> venyl plates are creat stuff !
[13:06:34] <gene78> yup, got motions within a thou now. Thanks for the hand holding. :)
[13:06:35] <zeeshan> archivist: what was that bike andy_pugh has?
[13:07:00] <archivist> ner a car
[13:07:40] <zeeshan> thank you
[13:08:08] <archivist> http://en.wikipedia.org/wiki/Ner-A-Car
[13:35:10] <IchGuckLive> im off BYE
[13:36:16] <gene78> making swarf, looks good so far
[13:42:42] <JT-Shop> yea
[13:43:42] <andypugh> <giggle> at Chinese quality. I just recieved a £25 steady-rest for my Chinese lathe. The threads are not concentric with the adjusters, but that’s a small issue compared to the fact that they simply forgot to cut the thread in one of the things that the adjuster screws in to.
[13:44:35] <zeeshan> lol
[13:44:48] <zeeshan> cheap chinese stuff is exactly that
[13:44:48] <zeeshan> cheap
[13:44:56] <zeeshan> moderate priced chinese stuff = win
[13:45:07] <zeeshan> ball screws is an exception
[13:45:11] <zeeshan> cheap ones are excellent!
[13:46:59] <deMimsy> Am I correct in stating that o-code cannot be run through AUTO_MODE?
[13:47:16] <archivist> I had the misfortune to see a remote stepper driver pcb the other day they have the red and black wires backwards, checked on fleabay, even the image was backwards
[13:49:26] <archivist> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=261472278611
[13:52:38] <gene78> deMimsy, GCode using o-codes, generally has to be restared from the top if stopped for some reason. I use lots o0f it.
[13:53:20] <deMimsy> hmm, for some reason if i open a file with any o-code statements in it, i cannot run it
[13:53:50] <deMimsy> however, if i call the ocode subroutines through mdi it runs just fine
[13:55:39] <andypugh> It’s not meant to be like that.
[13:56:22] <andypugh> Unless your code consists _only_ of O-sub code, in which case the G-code interpreter can’t see anything to run.
[13:57:00] <andypugh> One solution is probably (I only just thought of this) to have any subroutine file also contain a call to itself.
[13:59:06] <deMimsy> alright, i will attack it some more. just wanted to make sure I wasnt going down an unimplemented path
[13:59:22] <deMimsy> thanks!
[14:00:23] <JT-Shop> or the same number used more than one pair
[14:01:12] <JT-Shop> like o100 sub and matching o100 endsub and the next should be some other number
[14:01:57] <gene78> idea bounce time
[14:03:58] <gene78> I'm making a shaft extension for an 8mm screw. Thinking of boring a .5" deep pocket that just fits the screw's actual OD, slitting it, and putting a tapered thread on the end so when a nut is screwed on, it closed down on the end of the screw.
[14:04:03] <gene78> Workable?
[14:19:44] <MrSunshine> andypugh, yes but its hard sometimes =) as the probe move moves say 30mm down ... so i need to be sure i have Z axis 30mm above 0, and then i think it messes up even more if i have touched it off also :/
[14:20:44] <MrSunshine> so say i have a movement of 0 - -90mm on Z axis, i go down to -70 and zero my axis there, then try and do a probe move, it will complain about going outside of the axis movement and totaly mess up the classic ladder program :/
[14:25:53] <andypugh> gene78: Should work
[14:27:35] <andypugh> An alternative is what I did on my Y screw: A taper on the screw, a taper socket on the extension, and a differential screw to draw them together. This made sense for me as I only had access from the wnd when the screw was in place.

[14:50:38] <Deejay> re
[15:02:38] <FinboySlick> Completely off topic but since most of you are good at all things mechanical, I'm looking for this:
http://logan58.ru/image/cache/data/tovar1/655639-500x500.jpg in 2.25" in the US or Canada anyone here with inspiration? I've skimmed a few auto shops but can't seem to find anything past 2"
[15:05:01] <Loetmichel> hmm, try truck shops ;-)
[15:05:12] <Loetmichel> thats called "auspuffreparaturschelle" in german
[15:05:25] <Loetmichel> (exhaust repair clamp)
[15:05:47] <FinboySlick> Loetmichel: I always found the german way of concatenating words awesome.

[15:12:45] <archivist> Loetmichel, do you remember the name of bevel gear maker over there?
[15:13:05] <Loetmichel> no
[15:13:21] <Loetmichel> sorry
[15:14:53] <archivist> hmm, cant find in my book marks
[15:54:30] <zeeshan-laptop> hi
[16:14:20] <xxoxx> hi
[16:14:35] <jdh> cut anything yet?
[16:17:00] <zeeshan-laptop> no
[16:17:10] <zeeshan-laptop> jdh get your lathe runnng
[16:17:18] <zeeshan-laptop> btw, i got the long ball screw.
[16:17:28] <zeeshan-laptop> the extended ball screw will definitely work
[16:17:31] <zeeshan-laptop> no need to mount it outside
[16:35:47] <Deejay> gn
[16:50:24] <zeeshan-laptop> is deejay a bot

[20:07:21] <XXCoder> hey CaptHindsight ?
[20:08:53] <XXCoder> be back dinner
[20:19:05] <CaptHindsight> XXCoder: yoh
[20:31:23] <CaptHindsight> http://hackaday.com/2013/10/17/unorthodox-home-made-cnc-machine/ nothing quite smells of quality like fresh PVC for CNC! I think we need to have a contest for the worst CNC machine designs.
[20:31:44] <CaptHindsight> anything goes, including materials
[20:32:06] <CaptHindsight> http://www.youtube.com/watch?v=sCPXeZz72vM
[20:33:17] <XXCoder> back
[20:33:28] <XXCoder> I opened rails box
[20:33:35] <XXCoder> yep some issues with bearings lol
[20:33:49] <XXCoder> most is smooth just need grease (or oil?)
[20:34:01] <XXCoder> two only goes smoothly one direction
[20:34:08] <XXCoder> one is bit rough both ways
[21:30:57] <XXCoder> CaptHindsight: got good link on how to repack blocks bearings so all runs smoothly?
[21:35:46] <XXCoder> pipes cnc is awesopme, bad video though
[21:37:11] <CaptHindsight> XXCoder: are they sealed bearings?
[21:37:35] <XXCoder> maybe I used wrong word. things that move up and down rails?
[21:37:46] <CaptHindsight> bearing blocks
[21:37:50] <XXCoder> okay
[21:37:56] <CaptHindsight> are they crunchy?
[21:38:00] <XXCoder> how do I tell if sealed or not
[21:38:16] <XXCoder> I cant hear it so cant discribe as crunchy or not but one is definitely rough
[21:38:22] <XXCoder> and 2 is rough one direction
[21:38:26] <CaptHindsight> what type or rail round supported or prifile?
[21:38:31] <CaptHindsight> or/of
[21:38:33] <XXCoder> SBR rails
[21:38:36] <XXCoder> various sizes
[21:38:51] <CaptHindsight> heh, just a few that are out of round
[21:39:17] <CaptHindsight> all you can do it grease them up and hope for the best or just buy better bearings
[21:39:39] <XXCoder> so I just remove balls and clean then grease?
[21:39:48] <XXCoder> also any specific type of grease?
[21:40:06] <CaptHindsight> there's nothing to remove, do yours have grease fittings?
[21:41:16] <CaptHindsight> the are slightly oily from the factory so any grease will help
[21:41:49] <CaptHindsight> it's just cheap bearings, not much you can do
[21:42:05] <XXCoder> heh definitly have to clean em. saw few metal flakes
[21:42:27] <CaptHindsight> oh great
[21:42:43] <XXCoder> probably why some is "crunchy"
[21:42:43] <CaptHindsight> so metal shavings mixed in with the bearings
[21:42:54] <XXCoder> not a lot and wasnt in bearings just around
[21:43:02] <CaptHindsight> just don't lose any of the balls
[21:43:38] <XXCoder> yeah
[21:43:39] <CaptHindsight> if the person cared when assembling them they could have kept the work area clean
[21:43:52] <XXCoder> indeed. chinese dont I guess
[21:44:05] <CaptHindsight> so that should impact the manufacturing costs by much, unless they live in a sand dune
[21:44:07] <XXCoder> that specific company in leasy but most is like that anyway
[21:44:42] <XXCoder> okayt from what I can see
[21:44:52] <XXCoder> theres 4 olvious screw holes top
[21:45:02] <XXCoder> smaller one in middle for unknown use
[21:45:07] <XXCoder> side one for unknown use
[21:45:17] <XXCoder> My guess is tighter
[21:45:38] <XXCoder> makes bearing block stay on rail without any wiggle
[21:45:41] <CaptHindsight> maybe that screw is like that switch on that wall that doesn't seem to do anything
[21:47:23] <CaptHindsight> http://www.machinerylubrication.com/Read/28893/wd40-bearing-lubricant
[21:47:36] <XXCoder> its not lubucant
[21:47:40] <XXCoder> its water displacer
[21:48:47] <CaptHindsight> http://www.youtube.com/watch?v=0QL5hWmveIA
[21:49:25] <XXCoder> probably could be used as cutting "oil"? lol
[21:50:10] <XXCoder> not all types of greece are the same some greece's incompaytible because...
[21:50:24] <XXCoder> gonna love autocaption
[21:52:25] <CaptHindsight> http://www.machinerylubrication.com/Articles/Search?query=linear+bearing
[21:53:55] <XXCoder> yeah mine seems stright
[21:53:58] <XXCoder> good thing
[22:10:07] <XXCoder> saw one of big cnc machines at work running away making some airplane part
[22:10:20] <XXCoder> too bad I couldnt get close enoigh to take a good look.
[23:45:32] <FrankZappa> not all types of greece are the same some greece's incompaytible because the EU austerity measures have detrimental impacts on the strength of the economy.
[23:45:54] <XXCoder> :P
