[00:44:25] <ve7it> tjtr33, greatings.... a little late.... still trying to catch up with the irc backlog
[00:45:56] <tjtr33> np, someone was interested in your encoder. thanks!
[00:50:57] <ve7it> yea, it works great... one of these days I will replace the spindle and Z axis and put a VFD on the lathe drive
[00:51:18] <ve7it> or just buy a better mill!
[00:52:49] <MacGalempsy_> only took all day, but yes the touchscreen finally works right!
[00:52:53] <ve7it> but the shoptask is not a bad size for pcb work. but needs a high speed spindle and some work to reduce the flex and slop on some of the axis drives
[00:53:34] <tjtr33> well he's much better off with your advise. i gotta crash, thanks again!
[00:56:00] <ve7it> cheers
[00:57:01] <Cromaglious> wooohooo I have my first stepper working at home
[00:57:45] <Cromaglious> time to tear apart another printer for more steppers
[00:58:30] <Cromaglious> shortest DB25M/F cable 25 pin I had was 25 feet long
[00:58:50] <Cromaglious> err 25 wire
[01:04:18] <bobo_> zeeshan : how much water drained out of the transmission and the vertical head of your mill , before filling with new oil ?
[01:14:04] <Cromaglious> sheeeshz
[01:28:00] <SpeedEvil> http://www.ebay.co.uk/itm/HM6-Graphite-Electrode-Carbon-Block-Mold-Pattern-Glass-Blow-14x65x4cm-/141288148531#shpCntId - sort-of-on-topic
[01:40:44] <Cromaglious> hmmm I'd rather have a 5axis machine for working on that
[01:41:14] <Cromaglious> I got my 4th axis working on the 3040 at the CreatorSpace.us
[01:41:33] <Cromaglious> gantry REALLY needs to be raised
[01:46:44] <zeeshan> bobo none
[01:47:48] <Cromaglious> with the 4th axis in place there is not enough room under the X-Z carriage the chuck hit it. Even worse the jaws can stick up another 3/8"
[01:48:38] <Cromaglious> with the 4th axis in place there is not enough room under the X-Z carriage the chuck hit it. Even worse the jaws can stick up another 3/8"
[01:48:49] <Cromaglious> re MacGalempsy
[01:51:54] <Cromaglious> hmm I need to setup some screw terminal strips. at least 20 spots.. 40 screws
[01:52:32] <anarchos2_> http://blog.cnccookbook.com/2015/02/17/tormach-moves-mach3-linuxcnc-pathpilot/
[01:53:37] <Cromaglious> Hmm could use a 66 block and cat 5
[01:54:14] <anarchos2_> that article claims Toramch rewrote LinuxCNC trajectory planner.
[01:54:35] <anarchos2_> which in theory would have to be released under the GPL, eh?
[01:54:49] <anarchos2_> or they could just be using 2.7...
[01:55:02] <archivist> they did and it has been pushed back
[01:55:14] <zeeshan> grr
[01:55:22] <zeeshan> :/
[01:55:41] <anarchos2_> archivist: what's been pushed back, their release under GPL?
[01:56:14] <archivist> the new tp
[01:56:48] <anarchos2_> oh, from 2.7?
[01:56:52] <archivist> yes
[01:57:18] <anarchos2_> I see...and that's what Tormach is using, or their own TP?
[01:58:09] <archivist> there is only one new tp
[01:58:25] <anarchos2_> gotcha
[02:05:55] <Swapper> Feels pritty good to have swtiched to LCNC and "real" hardware :)
[02:06:14] <Swapper> from mach
[02:07:08] <zeeshan> :-)
[02:07:11] <zeeshan> congrads!
[02:07:37] <Swapper> in regards to tormachs desition to go the linux cnc whay that is
[02:07:57] <Swapper> Guess they had some problems getting turning to work in mach :)
[02:08:09] <Swapper> so they had to go linuxcnc or develop a whole new controller
[02:08:35] <Swapper> anyone know what mesa hardware is in the controller ?
[02:08:37] <zeeshan> develop is a strong word :P
[02:08:42] <MacGalempsy> ok the touchscreen workith!
[02:11:42] <Swapper> what would you guys recommend to use for a hardware feed override? i got a quadrature hand weel but maybe thats overkill ?
[02:12:05] <Swapper> have noticed i use the feed override a lot to not crash
[02:18:52] <archivist> I write the code on the machine so jog to a position and code that as an end point
[02:21:56] <Deejay> moin
[02:25:20] <MacGalempsy_> morning DJ
[02:25:24] <Cromaglious> I was cutting some Aluminum today and the Z limit/home switch was false triggering...
[02:26:11] <Cromaglious> think I need to go to a switch with a heavier spring
[02:29:46] <SpeedEvil> vibration?
[02:29:53] <Cromaglious> yep
[02:29:58] <SpeedEvil> Or flying chips :)
[02:30:44] <Cromaglious> Vibration.. Z deflects in the Y direction under heavier cuts
[02:33:43] <archivist> vibration is an error too
[02:34:20] <Cromaglious> which makes the switch go up and down, the direction the contacts move..
[02:34:57] <Cromaglious> slower feed rate then... and rewrite the file to get rid of most of the rapids
[02:35:16] <archivist> make the machine more rigid
[02:35:30] <Swapper> easier to lower the max speed in config ?
[02:35:34] <Cromaglious> it's a 3040 and it's not mine
[02:36:11] <Cromaglious> I am going to lean the gantry back to reclaim some of the table
[02:36:37] <Cromaglious> and raise it so it clears the A axis
[02:37:46] <Cromaglious> probably give it 120mm of clearance from 70ish
[02:38:24] <Cromaglious> really need to get a better spindle. It has a 230w
[02:40:03] <Cromaglious> I have optical limits coming
[02:41:33] <Swapper> i think inductive limits are the easiest to work with, needs some magnetic metal ofcorse
[02:41:51] <Swapper> and physical switches for e-stop
[02:41:59] <Swapper> mecanical
[02:42:03] <Swapper> is the right word :)
[02:42:57] <Cromaglious> I have 2 inductives coming as well
[02:44:15] <Cromaglious> inductive will probably be the Z limit & home
[02:45:25] <Cromaglious> I'll see how repeatable it is with the plate coming in from the side
[02:52:55] <Cromaglious> damn this nema 17 is freaking slow
[03:26:57] <MacGalempsy_> alright, back to the box. feeling good after finally figuring out that whole touchscreen deal
[03:27:10] <MacGalempsy_> now I can try and work with touchy...
[03:43:35] <MacGalempsy_> anyone around right now that can help me figure out why I cant get debounce to work in halcmd?
[03:52:02] <Tom_itx> Cromaglious, try debounce
[03:54:14] <Tom_itx> MacGalempsy, i'm using debounce in here if you wanna have a look: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/sherline.hal
[04:01:08] <MacGalempsy> ok
[04:01:24] <MacGalempsy> finishing up myu 0400 reports
[04:01:30] <MacGalempsy> then I can try it again
[04:01:48] <MacGalempsy> do you think the updates screwed up linuxcnc?
[04:11:34] <MacGalempsy> still no pins showing
[04:26:57] <MacGalempsy_> got it!
[05:53:16] <MacGalempsy> adios folks, my shift is over
[06:13:04] <jthornton> logger[mah] log
[06:13:35] <jthornton> logger[psha], log
[06:13:36] <logger[psha]> jthornton: Log stored at http://psha.org.ru/irc/%23linuxcnc/2015-02-18.html
[06:18:43] <_methods> aye aye aye too much jabber to read back from last night lol
[06:28:42] <jthornton> was trying to read yesterday but psah log stopped in 14 and mah log is broken
[06:29:59] <jthornton> CaptHindsight, I found two local projectors a Hitachi 3LCD with a dead bulb and an InFocus LP280. Either one of those work?
[06:32:03] <archivist> mine is more reliable http://emclog.archivist.info/
[06:32:34] <archivist> except when its not :)
[06:34:14] <jthornton> a little hard to read that color combination of yellow with yellow background
[06:34:48] <jthornton> looks like it drops the join part messages :)
[06:35:24] <archivist> I dont see those with the channel so they dont get recorded
[06:35:51] <archivist> never got round to debugging that any deeper
[06:48:54] <Loetmichel> hmm... i think i overdo it a bit... S24000, F3000, normal 90° countersink bit, 2mm deep in aluminium...finish: looks ok ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15663
[06:58:01] <_methods> Loetmichel: did you design your vacuum table?
[06:58:46] <Loetmichel> _methods: yes
[06:58:49] <_methods> nice
[06:59:23] <_methods> did you make drawings for it?
[07:00:29] <_methods> and how much have you had to modify your 6040?
[07:05:27] <_methods> Loetmichel: what size vacuum did you use for that table?
[07:07:41] <Loetmichel> no drawings, just the milling files
[07:08:06] <Loetmichel> not much, had to set the gantery 20mm higher to compensate the Vaacuum table
[07:08:36] <Loetmichel> normal industtrial shop vacuum cleaner
[07:10:00] <Loetmichel> ... the swarf form the chamfering of the heatsink in the pic above is flying tru the whole worksho... everything silver glittering ;-)
[07:10:17] <Loetmichel> +h
[07:33:04] <_methods> what did you use for the vacuum table material? pvc?
[07:50:54] <Loetmichel> _methods: 20mm PVC base and 8mm PVC top (sacrifical) plate
[07:52:25] <_methods> Loetmichel: thx
[07:52:56] <_methods> are you happy with it?
[07:54:25] <Loetmichel> it works
[07:56:23] <_methods> hahah
[07:56:27] <_methods> well that's all i need to know
[08:03:09] <jdh> make me one
[08:08:47] <__rob> anyone know what the offsets are here
[08:08:48] <__rob> http://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/2015/ENU/Inventor-HSM/files/GUID-315BB66F-4FFF-4803-A36B-4599F71720DD-htm.html
[08:09:00] <__rob> Index offsets for Length and Diameter
[10:05:33] <ssi> mawn
[10:06:49] <archivist> moan
[10:19:30] <jdh> I need some 0.030 neoprene gaskets cut
[10:19:39] <_methods> ouch
[10:19:41] <_methods> that's thin
[10:19:43] <_methods> punch
[10:19:52] <_methods> how big are the gaskets?
[10:20:01] <jdh> .6" circle with 7 holes
[10:20:23] <_methods> how many?
[10:20:27] <jdh> 2
[10:20:31] <_methods> oh lawd
[10:20:46] <_methods> xacto knife lol
[10:20:51] <Rab> ^^
[10:21:14] <jdh> thats why the current ones leak.
[10:21:27] <jdh> could use silicone
[10:21:41] <furrywolf> get a hollow punch set, a block of wood, and a hammer.
[10:21:47] <_methods> maybe try a sign shop
[10:21:48] <jdh> anyone have a laser?
[10:21:53] <_methods> on a vinyl cutter
[10:22:08] <_methods> might play hell on the knife though
[10:22:30] <_methods> i'm not sure how well neoprene cuts on laser
[10:22:33] <jdh> the holes are rg-178 size
[10:22:34] <Rab> It might need to be laminated with something a little less ductile, like paper.
[10:22:35] <_methods> but you could try that too
[10:23:05] <Rab> Or self-adhesive vinyl, could peel off when finished.
[10:24:03] <furrywolf> bbl, work
[10:25:25] <ssi> jdh: not anymore :(
[10:25:29] <ssi> it would have done that nicely though
[10:25:33] <ssi> I used to cut a lot of silicone gaskets
[10:25:52] <_methods> ssi did you build your laser or buy?
[10:25:57] <ssi> built
[10:26:01] <ssi> I'm gonna build another one soon
[10:26:03] <_methods> openbuild?
[10:26:20] <ssi> no, just made it up as I went along :P
[10:26:24] <_methods> k
[10:26:39] <ssi> I started with a shapeoko kit with longer rails, used their carriages
[10:26:42] <ssi> it worked out pretty well
[10:26:44] <_methods> i'm not sure if i want to build a laser next or plasma table
[10:27:01] <ssi> I didn't have a height adjustable bed though, and I ended up wishing i did
[10:27:16] <ssi> it was fine for cutting thin stuff, but you need a lot of travel for thick material plus long focus lenses
[10:27:52] <_methods> you had 120w?
[10:27:55] <ssi> yeah
[10:28:04] <_methods> can you cut 3/4 ply with it?
[10:28:16] <ssi> not with the lenses I had, but with long enough focus yes
[10:28:34] <_methods> 7.5" lens?
[10:28:35] <ssi> i could cut 1/2" ply with a 3" lens, but it was right on the edge
[10:28:39] <_methods> or is tha tway too big
[10:28:44] <ssi> and if there was a nasty glue void it wouldn't cut
[10:28:51] <ssi> 8" lens would probably do 3/4" beautifully
[10:28:57] <_methods> hmmmmm
[10:29:02] <_methods> decisions decisions
[10:29:05] <ssi> :)
[10:29:09] <ssi> I'm gonna design and build a new one soon
[10:29:18] <ssi> and it'll be 4x8', and capable of running an 8" lens
[10:29:43] <_methods> you get your lenses from II-VI
[10:29:44] <ssi> hm neoprene might be a bad idea actually
[10:29:46] <ssi> chlorinated
[10:29:55] <_methods> i was gonna say i think neoprene is bad to cut
[10:29:56] <ssi> I got my lenses from china :P
[10:30:21] <_methods> znse lenses?
[10:30:26] <ssi> yeah
[10:30:43] <_methods> how much are the 8"?
[10:30:46] <_methods> $400?
[10:30:53] <ssi> lol not from china
[10:30:57] <_methods> hmmm
[10:30:58] <ssi> nthey're all about the same price; probably around $50
[10:31:02] <_methods> wow
[10:31:03] <_methods> nice
[10:31:13] <_methods> how often you lose a lens?
[10:31:45] <ssi> I never lost one for any reason other than mishandling
[10:31:59] <_methods> you use gas assist?
[10:32:02] <ssi> yeah air
[10:32:08] <_methods> just shop air?
[10:32:16] <ssi> http://www.ebay.com/itm/New-ZnSe-Focal-Lens-CO2-Laser-Cutting-Diam-20mm-FL-1-1-5-2-2-5-3-4-/230838327998?pt=LH_DefaultDomain_0&var=&hash=item7b6ac62694
[10:32:20] <ssi> that's just up to 4", but $28 :P
[10:32:25] <ssi> yeah, but through a good dryer
[10:32:30] <_methods> oh yeah
[10:32:36] <ssi> I wanted to try O2 on steel
[10:32:38] <_methods> bad idea throwin oil in your beam path lol
[10:32:45] <_methods> or water
[10:32:47] <ssi> I tried to cut steel with air, and it just scratched
[10:32:50] <ssi> 28ga
[10:32:57] <_methods> yeah 120w............
[10:32:59] <_methods> not much power
[10:33:02] <ssi> no, not much
[10:33:09] <ssi> but it ought to cut thin stuff with the right optics and assist gas
[10:33:09] <_methods> you'd definitley need o2
[10:34:24] <ssi> I want to get set back up to cut wood though
[10:34:30] <ssi> I want to start doing laser cut wing kits
[10:39:07] <jdh> how thick?
[10:42:26] <ssi> what, the wing parts? they're thin
[10:42:30] <ssi> thickest material is 1/4"
[10:42:46] <ssi> 1/4" mahogany plywood
[10:42:50] <ssi> down to 1/32" birch plywood
[10:45:59] <jdh> wonder if a laser vendor would make me a few as a demo
[11:04:43] <CaptHindsight> http://www.smtnet.com/media/images/Techcon-TS5540-MS-Micro-Spr.jpg they want >$1K for this pneumatic operated spray nozzle
[11:06:38] <CaptHindsight> $100 airbrush and solenoid does the same thing
[11:06:49] <archivist> dont seem to have designed that to be held easily/accurately
[11:07:38] <CaptHindsight> there's a 4-5mm threaded hole on the opposite side of the body
[11:08:43] <CaptHindsight> https://www.youtube.com/watch?v=UqqR66sonqE
[11:09:50] <CaptHindsight> http://www.okinternational.com/File%20Library/Techcon/Products/Dispensing-Valves/ts5540-ms_data_sheet_2010.pdf 1/4-20 mounting hole
[11:11:16] <CaptHindsight> I'm not going to spend $30k on a couple dozen mini spray nozzles
[11:19:38] <Dan_> hello
[11:20:03] <Guest35479> is there anybody out there?
[11:20:13] <skunkworks> hello hello hello...
[11:20:20] * jdh nodz
[11:21:40] <Guest35479> Well played jdh
[11:22:38] <Guest35479> So I'm attempting to build the torch table on the Open Source Ecology site and I'm a bit over my head.
[11:23:06] <archivist> url?
[11:23:42] <Guest35479> I can't find the instructions on how to set up the stepper motors. http://opensourceecology.org/wiki/Torch_table
[11:25:13] <Guest35479> Also well played skunkworks.
[11:25:41] <archivist> I see their docs are out of date, they still call it EMC2
[11:25:59] <archivist> http://opensourceecology.org/wiki/CNC_Torch_Table/Manufacturing_Instructions#EMC2_motor_scale
[11:27:37] <archivist> see linuxcnc docs http://www.linuxcnc.org/docs/2.6/html/
[11:28:19] <Guest35479> Oh I haven't even gotten to that part yet I was actually talking about how to hook the motors and power supply up to my computer. I can't find those instructions anywhere.
[11:29:24] <archivist> in the integrators section of linuxcnc, and also your docs for any interface/breakout board you have
[11:30:30] <dirty_d> what cam software do you guys use?
[11:31:14] <jdh> mostly cut-2d for windows
[11:31:18] <archivist> inside rear of skull cam
[11:32:29] <Guest35479> I feel like I'm watching the Big Bang Theory and not getting any of the jokes.
[11:33:37] <dirty_d> hmm
[11:33:46] <archivist> there is no/little free 5 axis cam out there so I have to write it by hand
[11:33:57] <dirty_d> that sounds impossible
[11:34:02] <dirty_d> but i guess its not, lol
[11:34:13] <archivist> not as bad as you may expect
[11:34:24] <dirty_d> im thinking turbine blades
[11:34:35] <dirty_d> like in every 5 axis demo on youtube
[11:34:57] <Rab> Guest35479, the OSE people don't seem to be out of the prototype stage. On their bill of materials, there's a line item: "Xylotex 4 Axis Drive Box" "$460"...that's going to be something like this: http://xylotex.netfirms.com/OSCommerce/catalog/product_info.php?cPath=22&products_id=92&osCsid=da434ce2f555c759d96259d0abdbddfd
[11:35:19] <archivist> I make gears which are more regular
[11:36:00] <Rab> Guest35479, that's a complete drive system which hooks up to a computer parallel port.
[11:36:04] <dirty_d> taht sounds a lot easier
[11:36:29] <dirty_d> it seems like there isnt any 2.5d cam software for linyux thats even half way decent
[11:36:59] <dirty_d> ive resorted to writing gcode generating libraries and just coding parts
[11:37:05] <dirty_d> it kinda sucks though
[11:37:07] <skunkworks> ace converter (windows) dxf2gcode (both) and by hand
[11:37:25] <archivist> depends how you define decent and more important what you are making
[11:37:41] <dirty_d> just 2.5d stuff, no 3d
[11:39:20] <Guest35479> Hmmm... That looks completely different than what I have. I have the 4 stepper motors and a power supply and a mysterious circuit...
[11:39:41] <dr0w_> Speaking of Linux and CAM, I keep meaning to try HeeksCAM, anyone checked it out?
[11:39:55] <Rab> Guest35479, where did you get that hardware? Is there any branding on the "mysterious circuit"?
[11:40:01] <dirty_d> i just ran it in wine and it worked
[11:40:15] <dirty_d> but i didnt really do much
[11:40:15] <archivist> mysterious circuit is probably your breakout board which also has opto isolators
[11:40:37] <Rab> Guest35479, a photo might be worth a thousand words.
[11:41:38] <Guest35479> ok I'm starting to catch on. Thanks for everyone's patience. I've jsut figured out how to make fire so this is a tad challenging.
[11:42:42] <Rab> Guest35479, no worries.
[11:42:54] <archivist> like this example http://www.ebay.co.uk/itm/5-Axis-CNC-Breakout-Board-Interface-Adapter-For-Stepper-Motor-USB-DB25-Cable-/400699727113
[11:42:55] <Guest35479> http://www.skycraftsurplus.com/ProductImages/productimages4/sk3767.jpg so there's the power supply.
[11:44:51] <dirty_d> i just need cam to make stuff like this http://imgur.com/DW9yUcp.jpg
[11:45:22] <Guest35479> Oh I just found this. http://www.xylotex.com/XS3525V400.pdf I think it will help set it up.
[11:45:53] <Rab> Guest35479, is that your hardware?
[11:46:03] <dirty_d> i cut that the other day just testing the machine
[11:46:17] <dirty_d> still gotta figure out why the holes came out too big
[11:46:46] <Guest35479> Yes that's the hardware.
[11:47:34] <Rab> Guest35479, OK, pretty simple. You may need to build a cable to the computer's parallel port; page 5 shows the pinout.
[11:48:42] <Rab> In fact, that's what they're using: http://opensourceecology.org/wiki/Torch_Table_Bill_of_Materials
[11:50:35] <Guest35479> Ummm quick question... my computer doesn't have a parrall port. So I'll need to go from the Monitor port to the parallel port?
[11:50:38] <Rab> From there, it should just be a matter of configuring the software. This is a fairly generic setup.
[11:51:03] <Rab> No, the monitor port will not work. You'll need a computer with a parallel port.
[11:51:20] * SpeedEvil ponders I2C-linuxcnc
[11:51:35] <SpeedEvil> you could in principle do it over DDC, I think.
[11:51:42] <SpeedEvil> But yes - parallel port would be rather saner
[11:51:44] <Rab> Guest35479, and USB-to-parallel converters will not work for this application.
[11:52:35] <Guest35479> So that's like where you would plug in a printer?
[11:52:46] <Rab> Right.
[11:53:17] <Guest35479> Does anyone have the instructions on how to build a time machine to 1993?
[11:53:34] <Rab> Yes, but they took the instructions with them.
[11:53:37] <SpeedEvil> Many motherboards come with printer ports
[11:53:56] <SpeedEvil> they're often not brought out to the rear panel
[11:54:18] <Guest35479> Hmmm... OK how powerful does this computer need to be? Can I go by one at goodwill?
[11:54:47] <Guest35479> I was planning on buying a whole new computer for this project.
[11:54:57] <pcw_home> http://www.ebay.com/itm/281497643572
[11:55:49] <Guest35479> I mean I wasn't
[11:55:58] <Rab> Guest35479, this might give you a general idea: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hardware_Requirements
[11:56:04] <dirty_d> you could use a parallel port PCI card, $10
[11:56:30] <SpeedEvil> Check if your motherboard has a parallel port header
[11:56:53] <SpeedEvil> Otherwise, pcie-printer ports are very inexpensve
[11:56:54] <Guest35479> Oh that looks like nothing Rab.
[11:56:59] <Rab> pcw_home, has that box been successfully tested? Seems like a great deal.
[11:57:07] <pcw_home> Yes
[11:58:55] <Rab> Guest35479, the hardware doesn't have to be extraordinarily fast, but it does need low latency for real-time processing, which is a separate issue. Sometimes fast computers will still have latency issues.
[11:58:56] <Guest35479> Ok. Stupid question. I have a laptop. Is there some sort of external thing a ma jig I can buy to remedy this?
[11:59:30] <Rab> Guest35479, any card slots on the laptop and which type?
[12:00:01] <Rab> A laptop's not generally a great choice, but some work.
[12:00:27] <SpeedEvil> Port replicators for laptops ccan be non-USB and work well
[12:00:29] <Guest35479> I have an unused spot for a dvd.
[12:00:32] <SpeedEvil> but it really varies a lot
[12:00:59] * SpeedEvil imagines linuxcnc over SATA.
[12:01:05] <SpeedEvil> That's a _lot_ of steppers.
[12:01:53] <Rab> You should take a look at pcw_home's eBay link. The price is about as much as you'll pay for a good expresscard parallel port adapter, but it'll free up your laptop for other activities and will probably perform better.
[12:02:28] <Guest35479> Oh be right back... I might have an old computer in the shed.
[12:03:25] <dirty_d> i wonder how much work it would be to port linuxcnc's motion control code to run on a stm32
[12:03:44] <archivist> why bother
[12:03:46] <pcw_home> too slow
[12:03:50] <dirty_d> then just use a usb to have the gui control it
[12:03:56] <SpeedEvil> dirty_d: I was wondering the same about the esp8266
[12:04:00] <dirty_d> i dont think they are too slow
[12:04:06] <SpeedEvil> pcw_home: It is certainly not too slow
[12:04:10] <archivist> usb is a bad idea
[12:04:11] <dirty_d> i think the higher end ones are 200MHz
[12:04:27] <SpeedEvil> There are ones with 200MHz single-cycle FPUs and really flexible PWM units
[12:04:29] <dirty_d> and then you no longer need to jump through hoops to acheive timing requirements
[12:04:41] <dirty_d> and you can use any pc
[12:04:53] <dirty_d> and you just need a $20 piece of external hardware
[12:05:02] <SpeedEvil> I'm not sure how amenable the stack is to porting to something small.
[12:05:18] <SpeedEvil> AIUI,for a generic solution, you need to put the entirety of HAL into it
[12:05:21] <SpeedEvil> which is quite large
[12:05:31] <dirty_d> yea
[12:05:44] <Rab> There's somebody who did that, I think for PIC32. It's not open source, he sells the dongle.
[12:05:51] <dirty_d> wouldnt it make the HAL unneccesary?
[12:05:51] <SpeedEvil> For any given machine - it's quite trivial computationally to do
[12:06:07] <SpeedEvil> dirty_d: No.
[12:06:29] <SpeedEvil> dirty_d: Either you accept the round-trip latency between the PC and the device, or you put HAL on the device in some form
[12:06:30] <dirty_d> i feel like linuxcnc should be a peice of open source software, and a peice of open source hardware
[12:08:06] <SpeedEvil> Now the fun part after feelings.
[12:08:13] <dirty_d> lol
[12:08:21] <SpeedEvil> Supply patches, pay someone, convince someone.
[12:08:42] <Rab> Here it is: http://www.ecklersoft.com/
[12:08:45] <SpeedEvil> It's not a clearly ridiculous idea, but it is a fair amount of work.
[12:09:35] <archivist> a PC and a parallel port is pretty damned open
[12:10:32] <CaptHindsight> thinking about lost wax casting again the fastest, highest res and most accurate method is SLA (DLP or LCD) with a water soluble photopolymer, no heat is required so there's no thermal expansion of the mold during removal
[12:10:53] <dirty_d> i think if that architecture was used at the start of designing linuxcnc, it would have ended up simpler overall
[12:11:01] <Rab> Yeah, servo controllers seem to arise from the same calculus...if somebody is smart enough and does the work for a competent solution, they generally want to be paid for it.
[12:11:48] <archivist> servos have been driven off a parallel port too (not optimum but possible)
[12:11:50] <Rab> dirty_d, but it would depend on one specific peripheral. I think it's pretty neat that you can use FPGA boards, ethernet, whatever the market wants to provide.
[12:12:11] <cradek> if the linuxcnc architecture had been tied to a certain piece of non-commodity-pc hardware in 1993 it would be dead today
[12:12:46] <Rab> You would have been crazy not to use the parallel port in 1993. ^_^
[12:13:31] <dirty_d> the hardware would change along with the software
[12:13:31] <Rab> cradek, people would be searching for motherboards with an ISA slot.
[12:13:37] <dirty_d> but the point is that the hardware is cheap
[12:15:00] <Rab> dirty_d, I am totally in favor of that approach. I think the BBB is pretty close.
[12:15:24] <Rab> But I'm also pretty close to tossing the BBB and buying a $39 computer.
[12:15:34] <dirty_d> something like this would be better i think http://www.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=J2qbEwLrpCGdWLY96ibNeQ%3D%3D&kpid=608656256&gclid=Cj0KEQiAjZGnBRCOuJOUo9Xd0sUBEiQAPbicN6XUxm6eUDA7FJbjRiPnphp2QzDA-l4QLgSr1KoiejgaAlVU8P8HAQ
[12:16:07] <dirty_d> its better for realtime applications
[12:16:18] <Rab> dirty_d, I have two of those, so I encourage you to get cracking.
[12:16:21] <dirty_d> you have a plethora of hardware timers to use
[12:16:27] <cradek> the BBB is very cool, but is just a flash in the pan
[12:16:28] <dirty_d> me too
[12:16:57] <dirty_d> i already made a 3 axis controller, but it doesnt work with linuxcnc or gcode
[12:17:09] <dirty_d> im lazy
[12:17:23] <archivist> rather lacking in memory
[12:18:06] <dirty_d> you dont need much for the motion control
[12:18:18] <Rab> dirty_d, here's a standalone project for BBB: https://github.com/hzeller/beagleg
[12:18:19] <dirty_d> the pc would do 99% of the workload
[12:18:43] <ssi> dirty_d: you're just describing reprap-style drip fed motion control
[12:18:48] <ssi> which is very much not linuxcnc's aim
[12:18:55] <dirty_d> leave the gui and gcode processing to the PC and just let the external hardware coordinate motion
[12:19:31] <ssi> honestly BBB with hostmot fpga motion control would be a good solution,
[12:19:42] <ssi> but the sticking point seems to be that BBB doesn't have capable enough video hardware for the opengl preview
[12:20:10] <dirty_d> i think a laptop with a usb device is the ideal solution
[12:20:17] <ssi> I disagree :P
[12:20:21] <Rab> ssi, it's usable, but laggy.
[12:20:23] <ssi> laptops are expensive and the wrong solution
[12:20:32] <dirty_d> its portable so you can work on stuff at home and just bring it into the shop when you need to machine stuff
[12:21:34] <dirty_d> does linuxcnc control servo motors directly, or does it communicate with a servo controller?
[12:21:54] <CaptHindsight> didn't TI just release an ARM soc with the PRU's and a better GPU?
[12:22:05] <Rab> dirty_d, I think the answer is "yes"
[12:22:18] <dirty_d> both?
[12:23:06] <archivist> can handle proper servos and step dir types
[12:23:56] <CaptHindsight> http://www.ti.com/lsds/ti/arm/sitara_arm_cortex_a_processor/arm_cortex_a9_core/am437x_arm_cortex_a9/products.page?paramCriteria=no#p2103=1%203D
[12:24:15] <CaptHindsight> with 4 PRU's
[12:24:22] <Rab> dirty_d, I don't believe it would be possible to do servo control or other type of RT closed loop in LinuxCNC with the kind of abstraction you're talking about.
[12:24:28] <pcw_home> ugg powerVR again
[12:24:39] <dirty_d> Rab, i wouldn't think so either
[12:25:02] <CaptHindsight> http://www.ti.com/product/am4379
[12:25:16] <dirty_d> whats the typical interface to a servo controller?
[12:25:27] <dirty_d> like steppers have dir and step, what do you have with a servo?
[12:25:44] <CaptHindsight> analog +/-10V
[12:25:46] <pcw_home> if you want to run linuxcnc on a micro, that micro needs to run all of hal or you are just reinventing mach
[12:25:57] <Rab> For quasi-deterministic motion like steppers, you could just output step commands coupled with a calculated execution timestamp. The peripheral buffers the commands, and executes at the right time. I suspect that's how rt-stepper works.
[12:26:21] <dirty_d> Rab, thats what mine does
[12:26:25] <Rab> But you don't get any usable feedback.
[12:26:44] <dirty_d> well you can get feedback
[12:26:59] <SpeedEvil> It doesn't - quite - need to run all of HAL - it could run a 'compiled' subset. But in practice, that's going to be so much work to do, it probably does
[12:27:01] <dirty_d> tell it to step at x velocity until a switch or probe hits something, then stop, and report back the position
[12:27:25] <archivist> too late for geared motion
[12:27:46] <pcw_home> no realtime feedback to the control is not good for a profesional machine control
[12:28:02] <dirty_d> but the external hardware is the control
[12:28:10] <dirty_d> the pc software is just a gui and gcode processor
[12:28:17] <pcw_home> Unless you implement all of hal you aint got much
[12:28:20] <dirty_d> thats how i would envision it
[12:28:34] <pcw_home> mach...
[12:28:40] <archivist> nope, the pc has the control and the inter linking
[12:28:53] <dirty_d> well i know it does now
[12:28:57] <archivist> and mach does not work too well
[12:29:03] <dirty_d> but im saying there isnt any reason it couldnt work like that
[12:29:21] <archivist> look at the problems mach users run into
[12:29:24] <CaptHindsight> http://www.ti.com/lsds/ti/arm/keystone/products.page these have a DSP and price tags >$100
[12:29:28] <skunkworks> There isn't... But then you need to move a ton of stuff to your external hardware...
[12:31:47] <dirty_d> true, its a lot of work
[12:32:37] <archivist> we get a dreamer suggesting similar every few months
[12:32:47] <dirty_d> but once its done it works perfectly forever with way better realtime performance tahn youd ever get with a pc
[12:33:34] <dirty_d> if its ported to run on arm microcontrollers , then it would be pretty easy to move it to better ones as they appear in the market
[12:34:09] <pcw_home> Still to slow if you do anything mildly complex
[12:34:47] <dirty_d> whats complex?
[12:34:52] <jdh> tp and queueing
[12:34:57] <pcw_home> even 1.8 GHz atoms are too slow for some common linuxcnc uses (large classic ladder and servo thread faster than 2 KHz)
[12:34:57] <archivist> a hobbing machine
[12:35:13] <dirty_d> whats tp?
[12:35:24] <pcw_home> trajectory planning
[12:35:28] <archivist> trajectory planner
[12:35:34] <dirty_d> the pc would do that
[12:35:46] <archivist> exactly it has to be realtime
[12:35:51] <pcw_home> mach...
[12:35:52] <dirty_d> the external hardware only has to coordinate motion
[12:36:06] <dirty_d> no, the trajectory is deterministic
[12:36:06] <CaptHindsight> the other piece that people gloss over when imagining their new machine controller is all the flexibility, support and who is going to port to new platforms
[12:36:12] <archivist> wrong
[12:36:23] <dirty_d> archivist, i dont understand then
[12:36:30] <dirty_d> why isnt it deterministic?
[12:36:31] <archivist> load affects the planner
[12:37:30] <SpeedEvil> CaptHindsight: And what happens when the microcontroller of choice dies
[12:37:39] <dirty_d> im not following, i know the power to the servos etc needs to be realtime and non-deterministic, but your planned path is deterministic
[12:37:40] <SpeedEvil> (becomes out of stock)
[12:37:55] <SpeedEvil> dirty_d: Only if you have no feedback
[12:38:10] <archivist> dirty_d, no because of realtime feedback
[12:38:11] <pcw_home> or adaptive feed
[12:38:31] <_methods> http://laughingsquid.com/relatives-dress-a-deceased-man-as-green-lantern-and-stand-him-up-at-his-wake-because-he-was-a-hero-to-them/
[12:39:29] <Rab> The most common hobby/home shop use cases don't require feedback, though.
[12:39:39] <archivist> dirty_d, you have to see a geared operation like screw cutting or tapping to see it in action
[12:39:57] <_methods> just use an arduino and grbl
[12:39:58] <_methods> lol
[12:40:11] <_methods> like a bawse
[12:40:18] <dirty_d> what im thinking is that the PC software reads your gcode and calculates a trajectory based on the max velocity and acceleration youve set up, then tells the external hardware to execute that plan, and follow it as closeley as possible using feedback
[12:40:23] <dirty_d> or not in the case of steppers
[12:40:34] <skunkworks> feed override...
[12:40:36] <dirty_d> but the heavy calculations would have already been done on the PC
[12:40:42] <dirty_d> whats feed override
[12:40:52] <renesis> faster
[12:41:03] <archivist> dirty_d, when screw cutting on a lathe X has to respond to the spindle speed
[12:41:12] <archivist> I mean Z
[12:41:27] <skunkworks> or x.. (linuxcnc doesn't care... ;) )
[12:41:32] <dirty_d> i would consider that motion control and the responsibility of the external hardware
[12:41:37] <pcw_home> Buffered solutions are common and exist but carry many disadvantages
[12:41:41] <archivist> true, helical path :)
[12:41:56] <skunkworks> :)
[12:42:34] <archivist> dirty_d, but you happen to be wrong for motion under full control with feedback
[12:42:39] <dirty_d> the pc would tell the hardware to move the x axis a number of units for every number of radians on the spindle
[12:42:57] <SpeedEvil> That works for one case.
[12:43:02] <archivist> you are thinking open loop
[12:43:21] <dirty_d> archivist, no im thinking with feedback from the servos or encoders or whatever
[12:43:25] <archivist> closed loop is better
[12:43:30] <dirty_d> right
[12:43:41] <archivist> the loop is in the control
[12:43:46] <dirty_d> right
[12:43:56] <archivist> with the tp
[12:44:02] * Loetmichel should work a bit on his shielding of the Chinese mill
[12:44:22] <dirty_d> thats what im saying
[12:44:31] <Loetmichel> co.worker went into the workshop, started the drill press: mill lost about 50mm in y
[12:44:36] <SpeedEvil> Loetmichel: you mean put a sticker over the 'Made in China' label?
[12:44:47] <Loetmichel> lucily i saw it on the cam and could stop the mill ;-)
[12:45:23] <Loetmichel> i mean: its a bit sensitive to noise on the mains ;-)
[12:45:23] <_methods> what's fanuc use in their controllers for a processor for trajectory planning?
[12:45:46] <renesis> prob some ancient mcu
[12:45:55] <pcw_home> Not anymore
[12:46:01] <renesis> cool
[12:46:44] * Loetmichel made about one shopvac-bin full of little aluminium glitter today...
[12:47:04] <pcw_home> Lots of high end new systems use real time PCs and Ethercat
[12:47:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15663&g2_imageViewsIndex=1 <- pretty much in G0 ;-)
[12:47:29] <_methods> is that what fanuc is moving to?
[12:47:42] <Loetmichel> and wiht a normal 90° countersink bit ;-)
[12:47:56] <dirty_d> there are real time pcs?
[12:48:05] <pcw_home> Fabnuc is all proprietary AFAIK
[12:48:07] <_methods> man i need to go to a damn trade show i guess
[12:48:11] <pcw_home> Fanuc
[12:48:18] <_methods> been quite a few years since i've gone
[12:48:28] <jdh> Loetmichel: how much hassle to male the vacuum table?
[12:48:30] <_methods> i was going to go this year to mts in atlanta
[12:48:40] <Loetmichel> s24000, F3000, 2mm deep into the aluminium plates
[12:48:43] <Loetmichel> male?
[12:48:52] <renesis> make
[12:48:53] <Loetmichel> ah, make
[12:49:10] <Loetmichel> not really hassle, just a few hours of runtime
[12:49:29] <renesis> still no problems besides it sucking up a bit of coolant?
[12:49:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14682 <- mostly for that
[12:49:42] <Loetmichel> anbd then a few hours drilling ;-)
[12:49:49] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14685
[12:50:35] <Loetmichel> renesis: the shopvac is rated for water
[12:50:41] <Loetmichel> coolant isnt a problem ;-)
[12:50:56] <Loetmichel> the shopvac that operates the vacuum table
[12:50:57] <renesis> yesah realized this is another vacuum table project
[12:51:01] <Cromaglious> hmm older 3040
[12:51:02] <CaptHindsight> most vendors moved to PC for CNC control years ago, they just don't advertise the fact
[12:51:22] <renesis> capthindsight: its kind of obvious when you see the controllers, tho
[12:52:01] <renesis> like, theres an operating system there, its not just a bare bones UI looking all 80s vectorish
[12:52:01] <Loetmichel> Cromaglious: 6040 if you mean mine ;-)
[12:52:04] <CaptHindsight> $20k for a cnc controller is OK, but not for a PC
[12:54:08] <CaptHindsight> same for robot controllers
[12:57:25] <Cromaglious> im playing with a 3040 myself
[12:57:40] <jdh> how many mesa cards sold to oem's?
[12:58:39] <pcw_home> Most
[13:02:32] <ssi> not surprising
[13:09:50] <__rob> goes G68 work properly in LinuxCNC ?
[13:09:57] <__rob> trying it in Mach3 and its all broken
[13:14:18] <skunkworks> __rob, corrdinate rotation? Look at G10... (there isn't a g68 in linuxcnc)
[13:14:46] <__rob> ahh
[13:14:56] <__rob> so in Mach3 it makes my arcs go nuts
[13:15:04] <skunkworks> and yes - it works great
[13:15:05] <__rob> no idea why, its all basic trig
[13:15:24] <skunkworks> riiiight...
[13:15:30] <_methods> lol
[13:15:44] <__rob> to move x and y coordinates around for a 2.5 d machine is simple stuff
[13:16:04] <_methods> there are all kinds of other considerations
[13:16:08] <_methods> besides just "moving"
[13:16:18] <_methods> how does it affect coordinate systems
[13:16:30] <_methods> does it rotate all of them
[13:16:33] <_methods> just the current
[13:16:49] <skunkworks> http://electronicsam.com/images/KandT/testing/rotate1.png
[13:17:07] <__rob> yea, I'm sure there are complexities
[13:17:28] <__rob> but the actual tranposing of coordinates, whether you do it multiple times or not is just a matrix multiplication
[13:18:00] <__rob> and it looks like hes removed it in mach4
[13:18:11] <_methods> probably because it is so easy to do
[13:18:36] <skunkworks> like everything else that gets asked - it will be added after things settle down..
[13:18:42] <__rob> well, not saying its easy
[13:18:54] <__rob> but if I was making that software full time
[13:18:57] <__rob> i'd get it done
[13:19:45] <_methods> well mach3 is diff people are payin for that
[13:19:55] <_methods> so feel free to complain lol
[13:20:10] <__rob> exactly, and looks like its working in linux cnc :P
[13:20:25] <__rob> from what skunkworks pasted
[13:20:46] <__rob> I was actually really hoping it would, so I could just flip the part, not worry about squaring it
[13:21:09] <__rob> then just write a script to choose the offsets, and have it set the angle and x,y
[13:21:18] <Cromaglious> http://s172.photobucket.com/user/Robi_Akerley_McKee/library

[13:41:27] <FinboySlick> __rob: Looks to me like it wouldn't produce the same part ;)
[13:45:36] <PetefromTn_> apparently not..
[14:08:41] <__rob> nope
[14:08:44] <__rob> it wouldn't

[14:11:48] <PetefromTn_> agreed
[14:12:01] * _methods stays out of religious wars
[14:12:10] <Connor> So, my neighbor, instead of cutting the branch hanging over my power line like I asked... stuck a 2x4 under it to get it off my line.. Which was nice.. I didn't even think of it.. but.. I'm a tad concerned because wind is suppose to get really bad tonight... I don't think the 2x4 is going to help much...
[14:12:51] <jdh> it is going to fall and hurt something
[14:13:32] <Connor> No. But if the wind picks up.. it could lift the branch off of it, or something and the branch can come down ontop of my line again, only with more weight and force.. and POOF no power.
[14:13:50] <PetefromTn_> cut the fucker down..
[14:14:03] <CaptHindsight> I once cut a tree down in my neighbors yard to prevent that
[14:14:15] <CaptHindsight> they didn't mind if I did the labor
[14:14:51] <Connor> I really have no way to do it safely. All I have is a Ryobi 18v chain saw.. and I would have to be on a ladder to get to the branch.
[14:15:31] <PetefromTn_> MY japanese pine tree has loaded up with ice and several of the branches fell down onto my power leads to my house the other night. Happened at 2AM.
[14:15:41] <Connor> the last thing me or wife needs is me in the hospital with broken arm, leg or neck..
[14:15:56] <PetefromTn_> I went out there with a long piece of wood and started whacking on the ice...
[14:16:13] <PetefromTn_> the needles and branches were so cold they mostly just shattered and broke
[14:16:32] <Connor> Yea.. my power head has been pulled through the roof about 2" or so...
[14:16:33] <PetefromTn_> now that branch is in it's normal position again only with a few less ends
[14:16:41] <Connor> before this winter ice stuff..
[14:16:49] <PetefromTn_> the rest of the tree is in kind of bad shape now
[14:17:07] <PetefromTn_> I MAY wind up having to climb that thing and start cutting it down from the top down...
[14:17:22] <Connor> Ick
[14:18:04] <PetefromTn_> That will be the third of four trees on my property that have been killed by weather here. All I have left is one bradford Pair tree in the front yard and shrubs now if this one dies...
[14:18:26] <PetefromTn_> One of the main reasons I bought this house was a beautiful weeping willow tree in the back yard
[14:18:38] <PetefromTn_> that thing lasted not even one year after we moved in.
[14:18:47] <_methods> geez
[14:18:48] <_methods> that sux
[14:18:51] <PetefromTn_> big lightning strike ripped it in half..
[14:19:17] <PetefromTn_> yeah I really like those trees even tho they are a pain in the ass to clean under...
[14:22:23] <Cromaglious> as a kid my grandpa had one in his back yard, my brother and I would do the tarzan thing swinging on the branches
[14:23:17] <PetefromTn_> yup it is my Grandmother's favorite tree too. She insisted my grandfather plant one on every piece of property they ever owned LOL...
[14:32:19] <Tom_itx> Connor go out in the middle of the night and cut the branch off
[14:33:02] <Tom_itx> PetefromTn_ we had lightening hit a tree out front... it ploughed the ground at the base of the tree
[14:35:34] <Tom_itx> i think the tree will live but the bark is peeling on one side
[14:36:14] <PetefromTn_> yeah that is kind of what happened to this tree..
[14:36:38] <PetefromTn_> It actually looked okay from the outside except for one of the main spars out of two had been sheared off.
[14:36:49] <Tom_itx> usually you can count between sight and sound but not on this one :D
[14:36:52] <PetefromTn_> but when we cut the thing down it was pretty well destroyed inside
[14:37:06] <PetefromTn_> Oh yeah it shook our whole house LOL
[14:37:21] <PetefromTn_> sounded like a bomb went off or something
[14:37:37] <PetefromTn_> the tree was maybe fifteen yards from my back porch
[14:37:58] <Tom_itx> about the same here
[14:38:04] <Tom_itx> if that far
[14:38:37] <Tom_itx> ok i think i've gathered enough crap i can get this spindle working today hopefully
[14:39:19] <Tom_itx> i need to test the relay outputs though to make sure one is firing before the other
[14:39:20] <PetefromTn_> I thought you already had it working
[14:39:26] <Tom_itx> not reverse
[14:39:30] <Tom_itx> fwd is
[14:39:33] <PetefromTn_> ah
[14:39:44] <Tom_itx> and i was gonna add PID just because...
[14:39:52] <PetefromTn_> its so cold out in the shop I have not even bothered to go out there today.
[14:39:57] <Tom_itx> it's not needed but it's a learning thing with me
[14:40:02] <PetefromTn_> my kids are off apparenlty all week now.
[14:40:14] <Tom_itx> netflix time
[14:40:26] <Tom_itx> do redbox?
[14:40:35] <PetefromTn_> yeah I have been sitting here doing some Cad drawings and design work
[14:40:42] <PetefromTn_> yeah we do redbox
[14:40:48] <Tom_itx> 727272 to SHOWTME and get a free one
[14:40:49] <PetefromTn_> even got a free one waiting
[14:40:51] <Tom_itx> that or MOVIETIME
[14:40:58] <Tom_itx> i forget
[14:41:08] <PetefromTn_> did not know that
[14:41:21] <PetefromTn_> but it is still pretty shitty and icy here on the roads
[14:41:21] <Tom_itx> we get those from time to time
[14:41:27] <PetefromTn_> been kinda keeping inside
[14:41:53] <PetefromTn_> Don't really feel like cracking up my truck just to get some movies hehe
[14:41:58] <Tom_itx> got 4 phones so i got 4 free rentals :D
[14:42:12] <PetefromTn_> Oh yeah you can do it more than once heh
[14:42:21] <PetefromTn_> we have three phones here HMmm
[14:43:54] <PetefromTn_> http://knoxville.craigslist.org/tls/4892987942.html Half tempted to buy this just for the headstock LOL..
[14:45:57] <PetefromTn_> http://chattanooga.craigslist.org/tls/4887393956.html LOL $2k??????
[14:45:59] <Tom_itx> .. it's MOVIETIME just checked
[14:46:17] <Tom_itx> caps
[14:46:19] <PetefromTn_> you just text movietime to 727272?
[14:46:26] <Tom_itx> no just the opposite
[14:46:51] <PetefromTn_> do they kill your damn phone with offers and junk after that?
[14:47:06] <Tom_itx> i dunno i didn't do it on mine :D
[14:47:12] <Tom_itx> i don't think so
[14:47:18] <Tom_itx> they haven't yet
[14:47:21] <PetefromTn_> LOL I see what you did there....
[14:47:33] <Tom_itx> she's had 4 at once before
[14:47:56] <Tom_itx> so use 3 cc and do the math there
[14:48:10] <PetefromTn_> http://chattanooga.craigslist.org/tld/4868688785.html This looks like a sweet machine....
[14:48:53] <Tom_itx> nice size
[14:49:01] <Rab> Watch out, those codes are only good for a day and you have to give a CC at the kiosk. If you return late, you automatically get charged.
[14:49:16] <Tom_itx> right
[14:49:22] <Rab> I don't remember if "1 day" means 24 hours, or next day at midnight, or what.
[14:49:26] <Tom_itx> but knowing that going in just return it
[14:49:54] <Tom_itx> you need a cc at the kiosk anyway
[14:50:04] <PetefromTn_> yeah we do it all the time.. have paid late fees several times too heh
[14:50:42] <Tom_itx> that one you have a week to use
[14:50:44] <PetefromTn_> It's kind of a Friday thing for us around here.. get the newest releases and wind up keeping them til' sunday morning to watch them hehe
[14:50:48] <Tom_itx> once activated
[14:53:01] <PetefromTn_> http://charlotte.craigslist.org/tls/4895224729.html This could be a neat little CNC collet lathe hehe...
[14:55:08] <PetefromTn_> http://louisville.craigslist.org/tls/4854275262.html
[14:59:50] <Rab> Watch out, that B&W photo depicts the lathe as it was originally put into service.
[15:00:48] <_methods> heh i have one of those little hardinges here at the shop
[15:03:29] <PetefromTn_> there is a build thread somwhere that a guy took a Feeler version and built a nice XY slide table that mounted on the large dovetail on the same basic machine. Looked pretty cool....
[15:04:46] <jdh> its about 5miles from my house
[15:05:29] <jdh> awfully big for such a small lathe
[15:08:14] <oceax> I want to do rigid tapping, but i have a 2.2kw vfd spindle => no torque at low rpm. Would buying mesa 7i77, a servo motor and create a belt drive to my 2.2kw spindle be a good solution?
[15:18:14] <PCW> Have you tried tapping with the spindle?
[15:20:32] <oceax> No i have only done tapping by hand before. But from what i have read online it should not work well with my type of spindle.
[15:22:16] <furrywolf> speaking of rigid tapping, can linuxcnc do single-point threading on a mill? that is, set the spindle speed down really low, and put an internal threading in the chuck, and synchronize its movement down into the workpiece? will need to synchronize both the z travel (easy, that's just rigid tapping) and helically (harder?).
[15:23:35] <rob_h> wouldt one just thread mill it instead?
[15:23:51] <furrywolf> you could, yes.
[15:24:01] <rob_h> i know not as fun tho right
[15:24:18] <furrywolf> right. :P
[15:25:02] <furrywolf> anyway, the question is "can linuxcnc do", not "is it the best way" :)
[15:25:22] <rob_h> i bet it could not alot it cant if u put your mind to it
[15:25:40] <FinboySlick> furrywolf: LinuxCNC can do *everything*.
[15:26:04] <FinboySlick> You may need to write a patch though ;)
[15:26:23] <rob_h> it dosnt clean up the chips too well after its self tho thats for sure i always end up doing that
[15:26:30] <CaptHindsight> or very creative Gcode
[15:27:11] <FinboySlick> rob_h: OpenCV, multi-axis arm, vacuum... You're set.
[15:27:45] <CaptHindsight> chip sucker attachment
[15:28:05] <FinboySlick> That doesn't look nearly as cool though.
[15:28:55] <_methods> jarvis
[15:29:15] <FinboySlick> Now that would be a conversational interface.
[15:29:39] <_methods> or should i say j.a.r.v.i.s
[15:29:43] <_methods> l.o.l.
[15:29:51] <CaptHindsight> spent the afternoon talking to airbrush manufacturers, I feel the same now after standing in line for 2 hours at the DMV
[15:29:52] <furrywolf> single-point threading with the mill would require either a very slow spindle or pretty fast axis acceleration... not sure my machine could do it anyway. heh.
[15:31:27] <furrywolf> airbrush manufacturers are that bad, eh?
[15:32:38] <furrywolf> because after the dmv, I usually feel like killing people.
[15:32:51] <CaptHindsight> 99% of there customers questions must be "How come every time I press the trigger it squirts in my eyes?"
[15:33:09] <CaptHindsight> "are you holding it backwards?"
[15:33:21] <furrywolf> lol
[15:33:40] <furrywolf> or some variant of "how come my art doesn't sell?" "because you suck."
[15:33:54] <CaptHindsight> must be the brush :)
[15:34:23] * furrywolf notes most airbrush "artists" are fucking awful
[15:34:43] <CaptHindsight> it's best for Elvis on black velvet

[16:10:55] <alex4nder> hey
[16:11:01] <jims> I have a question abut 4th axis display.
[16:11:14] <jims> Any takers?
[16:12:22] <micges> just ask
[16:13:01] <micges> who knows will answer
[16:15:06] <jims> In Axis, my display shows the tool rotating about the "point of the cone" instead of tracing a path about the axis of rotation, that is the X axis. Do you know of a setting to change this?
[16:17:04] <jims> There is a YouTube video doing just what I want, so I know it's possible, but I am stumped.
[16:17:40] <micges> jims: http://www.linuxcnc.org/docs/2.7/html/config/ini_config.html#sub:DISPLAY-section
[16:17:47] <micges> look for GEOMETRY
[16:18:55] <jims> I set that to GEOMETRY = XYZA, but no luck.
[16:19:36] <micges> try AXYZ
[16:20:55] <jims> I don't have access to the machine, but will give it a try tomorrow.
[16:22:08] <tjtr33> __rob, planes tilted in 3d ( was playing with a kinematics to allow this ) http://ibin.co/1s7bMb0Ew3qU
[16:24:48] <jims> The machine works fine, it's just that the display as shown is not helpful.
[16:26:23] <micges> jims: combine those 4 letters, I can't remember exactly which is correct
[16:26:58] <jims> Will do, thanks in advance.
[17:44:44] * JT-Shop has been battling snow all day and calls it quits

[18:11:49] <MrSunshine> try installing it to a custom path then doing LD_LIBRARY_PATH=path ./install

[20:27:42] <PCW> Yeah up 8 channels/port 4 ports max
[20:28:24] <MacGalempsy> I guess trying to use 7i77x2 with the 7i77 and 7i84 is a bad attempts?
[20:28:33] <MacGalempsy> got the pins showing
[20:29:27] <PCW> should be fine
[20:31:14] <MacGalempsy> ok. we'll see how things go. with it moving on 3 axis with the old linuxcnc, those seem to be hooked up fine. i am more concerned about the vfd, and possible screwing it up
[20:34:08] <MacGalempsy> PCW: what is the differnce between 7i77x2 and 7i77x2 with one 7i77?
[20:35:13] <PCW> just the tabs that pncconf presents AFAIK
[20:35:29] <MacGalempsy> ok
[20:36:25] <MacGalempsy> so with the combo that is running, the smart serial port is set to 1, but what is the significance of changing the number of channels(trying to figure out the correct setting
[20:36:56] <PCW> No idea, not a pncconf expert
[20:37:03] <MacGalempsy> heh. ok.
[20:37:47] <PCW> in hal the ports are 0..3 as channels are 0..7
[20:39:07] <PCW> on (the first) 7i77 the channels are
[20:39:09] <PCW> 0 Digital I/O
[20:39:11] <PCW> 1 Analog out
[20:39:12] <PCW> 2 Expansion connector
[20:39:36] <PCW> all on port 0
[20:39:56] <PCW> bbl
[21:04:54] <anarchos2_> anyone had any success embedding "features" into gmoccapy?
[21:06:37] <furrywolf> spent today working on cars instead of the mill... working on another subaru engine swap. putting a newer engine into an old brat. needed bellhousing adapter plate and flywheel spacer.
[21:06:50] <XXCoder1> fun
[21:08:53] <furrywolf> sigh, reading the news... 18 people killed in a stampede. one person was shocked by hitting electrical wires, and is expected to live. not a major disaster. but then people panic, and STEP ON OTHER PEOPLE. wtf?
[21:11:14] <Cromaglious> during a stampede ALWAYS head for the side
[21:12:05] <XXCoder1> mob menlity
[21:12:35] <furrywolf> they weren't even running from anything! one person contacted electrical wires, and was shocked. there never was any threat to anyone else, nor any conceivable way people could think there was a threat.
[21:14:28] <XXCoder1> thats weird.
[21:15:27] <furrywolf> all the more reason to avoid ever attending things with lots of people.
[21:15:42] <anarchos2_> i can get it to embed and show up, but none of the buttons or anything like that work
[21:22:20] <furrywolf> I asked this before, but no one seemed to be around... I need some collets for my mill. I'm thinking of going with ER. should I get ER20 (1/2" max) or ER25 (5/8" max)? also, the sets of collets in 1mm increments should be adequate for inch-sized bits, right? I suspect the chinese sets advertised with inch sizes are in fact just the metric ones relabeled, since they picked weird sizes...
[21:23:49] <evil_ren> mine are reg spaced inch
[21:24:03] <evil_ren> 1/8, 3/16, 1/4, etc
[21:24:09] <furrywolf> are they an affordable chinese set? heh. yes, I know US manufacturers make proper inch-sized sets.
[21:24:17] <evil_ren> but yeah the inch and mm ones are spaced pretty close
[21:24:28] <evil_ren> i think mine came from taig
[21:24:35] <furrywolf> but the chinese set I was looking at was weird, and has things like 3/64 but no 1/16, making me think they're just the metric ones labeled as the closest inch size...
[21:24:42] <evil_ren> the couple replacements i got are from enco, prob chinese
[21:25:06] <evil_ren> theyre spring collets so they can get away with that, heh
[21:25:18] <XXCoder1> or make your own? lol jk
[21:25:30] <XXCoder1> I bet its bit tough
[21:26:12] <furrywolf> 1-16mm metric sets are $38, inch-labeled sets $90...
[21:27:57] <furrywolf> should I go with er20 or er25? does my chinese mill/lathe combo have the power and rigidity to push anything with a 5/8" shank around?
[21:28:53] <evil_ren> lighter materials, side cutting roughing endmills, id go big
[21:29:33] <evil_ren> just gives you more options
[21:30:26] <evil_ren> unless its like way more $$$
[21:30:30] <furrywolf> also gives me less money and less tool-to-table height...
[21:30:49] <XXCoder1> slow collet collection growth?
[21:30:55] <XXCoder1> may be able to afford that
[21:31:18] <alex4nder> furrywolf: what mill?
[21:32:08] <furrywolf> alex_joni: old shoptask mill/lathe combo
[21:32:34] <furrywolf> http://fw.bushytails.net/shoptask02.jpg (old photo - now has working cnc)
[21:32:47] <alex4nder> ah cool
[21:33:30] <XXCoder1> lathe mill. cant image how it works. guess I didnt work at mills enough
[21:33:34] <XXCoder1> my work dont own one
[21:34:03] <alex4nder> furrywolf: Re: cheap collet labeling.. yah, that happens a lot on the cheap end. and it works, because the collets have clamping ranges.
[21:34:27] <furrywolf> I'm definitely looking at the cheap end.
[21:35:03] <furrywolf> XXCoder1: imagine a milling head stuck over a lathe, and you have one.
[21:35:17] <XXCoder1> yah saw your pic
[21:38:11] <alex4nder> I just ordered up a taig mill, and a 7i76e to go with it
[21:38:25] <alex4nder> which,... with the er16 spindle is.. small
[21:39:43] <furrywolf> grrrr. I need to shop somewhere other than ebay. ebay's new hiding the item description is so annoying it's difficult to shop there.
[21:40:31] <XXCoder1> fur youre a programmer eh
[21:40:53] <furrywolf> somewhat. I'm a lot of things. do you have a programming question?
[21:41:06] <XXCoder1> nah just was curious when I saw few c files
[21:59:00] <furrywolf> I find all these sets with odd 32ths sizes but not standard sizes to be highly suspect. I might as well just get ones labeled in metric. heh.
[21:59:55] <XXCoder1> yeah
[22:00:03] <XXCoder1> as long as those can hold whatever tools you need it to
[22:00:17] <furrywolf> I think including 3/64 instead of 1/16 might as well be a big sticker saying "these are really metric".
[22:03:23] <furrywolf> http://www.ctctools.biz/ anyone ever order from them? I'm guessing not, seems like small chinese dealer...
[22:03:52] <furrywolf> their site is, however, engrish-free, which is quite a pleasant change for goods shipped from china.
[22:03:52] <jdh> I got an ER collet set from cdco toos
[22:04:31] <furrywolf> Rm13, 13F, World-Wide Ind. Centre, 43-47 Shan Mei Street, Fotan Shatin NT, Hong Kong and they're honest about where they are. :)
[22:04:45] <alex4nder> furrywolf: as long as you can cover a continuous range of clamping, metric vs. standard doesn't really matter
[22:06:05] <furrywolf> alex_joni: the metric ones come in 1mm increments and claim a 1mm clamping range. :)
[22:08:35] <alex4nder> furrywolf: so then you've got your standard measurements covered
[22:09:41] <furrywolf> meh, tooling costs too much. :(
[22:10:00] <furrywolf> how is anyone supposed to afford to have a variety of tooling at new prices?
[22:11:17] <alex4nder> if you're willing to buy chinese, it's not so bad
[22:11:41] <furrywolf> yes, it is. I'm trying to find cheapo indexable lathe tools, and not finding cheap.
[22:12:20] <alex4nder> $30 on ebay?
[22:12:40] <furrywolf> even harbor freight wants $25 just for 1/4" tools.
[22:12:45] <alex4nder> they'll probably give you cancer, but .. that's cheap
[22:12:54] <XXCoder1> is regular converting to indexable possible?
[22:13:23] <furrywolf> it'd be easier to convert a piece of steel bar into a toolholder than to start with one that already has something brazed to the end. :)
[22:13:30] <XXCoder1> lol ok
[22:15:13] * furrywolf doesn't consider "having to work for three hours just to purchase a tiny accessory" to be cheap
[22:24:06] <XXCoder1> wow http://www.technologyreview.com/news/534796/nano-manufacturing-makes-steel-10-times-stronger/
[22:28:22] <furrywolf> how, exactly, do they propose an electroplated coating makes steel ten times stronger?
[22:29:02] <furrywolf> sure, you can electroplate an inch of expensive metal onto a piece of cheap steel, and it'll be a lot stronger... but that's not useful.
[22:29:10] <XXCoder1> yeah dunno
[22:29:23] * furrywolf smells "give us money".
[22:30:08] <furrywolf> also, bulk electroplating like that is quite expensive. it's why metals obtained through electrolytic processes are expensive...
[22:30:37] <XXCoder1> thats why I pasted here, im not expert heh
[22:33:08] <MacGalempsy> anyone got a script that runs a mill back and forth to warm it up?
[22:33:20] <MacGalempsy> its so cold, I am starting to get following errors
[22:33:34] <furrywolf> as a general rule, anything that looks like a press release and lacks any details whatsoever, and mentions things like "will", "should", "up to", etc, is bull.
[22:33:36] <XXCoder1> sounds like simple g code
[22:33:50] <furrywolf> MacGalempsy: g0 x+10 g0 x0 etc? :P
[22:33:59] <Cromaglious> oh wow! I still own itslinux.org and itslinux.com
[22:34:16] <furrywolf> s/+10/10
[22:34:52] <XXCoder1> yeah fur
[22:34:52] <furrywolf> any idea where I can get a mt3 extension that has a hole for a drawbar to run through it?
[22:34:55] <XXCoder1> that should work
[22:35:11] <XXCoder1> hell if starting too fast causes errors
[22:35:13] <XXCoder1> start slow
[22:35:21] <XXCoder1> then increase speed as it warms up
[22:35:21] <furrywolf> there's tons of them out there, but they all have tangs...
[22:35:32] <furrywolf> I could bore one out, but I might as well just get what I want.
[22:36:04] <furrywolf> or I could just make a 3" thick spacer for the table...
[22:36:13] <furrywolf> stupid mill only having 3" z travel!
[22:37:56] <XXCoder1> for mill thats pretty sucky
[22:38:05] <XXCoder1> my cnc rputer has similiar clearance
[22:40:59] <Cromaglious> furrywolf, I saw something like that awhile back... Search for mt3 sleeve
[22:41:22] <furrywolf> yes, I've seen lots of them... but none with a through-hole for a drawbar.
[22:42:26] <furrywolf> it's probably better to raise the vise than extend the spindle anyway, for runout and rigidity.
[22:42:33] <XXCoder1> interesting https://i.chzbgr.com/maxW500/8448402688/h1B2E66C6/
[22:42:43] <Cromaglious> furrywolf, http://www.ebay.com/itm/like/231174784106?lpid=82&chn=ps
[22:43:33] <Cromaglious> hole at both ends
[22:43:43] <furrywolf> yes, that's mt3 to mt2, not an mt3 extension like I asked about.
[22:43:57] <Cromaglious> oh you want mt3 to mt3
[22:47:40] <furrywolf> yes
[22:47:49] <Cromaglious> http://shopmasterusa.com/tools-complete-list/290-m3-m3-morse-taper-extension.html
[22:48:12] <Cromaglious> outside is draw bar ready.. dunno about the inside
[22:49:59] <furrywolf> http://humboldt.craigslist.org/tls/4897589754.html tempting...
[22:50:20] <XXCoder1> pretty cheap
[22:50:34] <XXCoder1> forgot what harbor metal lathe price was thoygh
[22:51:10] <furrywolf> I'd assume anything that old is better than anything you can get at hf right now. heh.
[22:51:26] <XXCoder1> lol yea
[22:51:51] <Cromaglious> ugh change gears
[22:52:14] <Cromaglious> I do need a 3 jaw chuck for my sheldon and a QCTP as well
[22:52:53] <furrywolf> Cromaglious: hrmm, that might just be what I need. It would figure it's from the same company as my mill... probably a common complaint!
[22:53:17] <furrywolf> (shopmaster makes (or, at least, tells china to make) my shoptask mill/lathe combo)
[22:54:36] <Cromaglious> hehe
[22:54:57] <Cromaglious> ST16 is the tool number
[22:58:06] <furrywolf> why are indexable carbide tools so much more expensive than brazed tips? you'd think drilling and tapping a hole would be cheaper than brazing...
[22:58:21] <MacGalempsy> in 2.6 what is the replacement for gedit?
[22:58:37] <Tom_itx> ?
[22:58:44] <Tom_itx> i installed gedit :D
[22:58:51] <MacGalempsy> ah ok I need to install
[22:59:00] <XXCoder1> emacs is awesome if you take time
[23:00:05] <MacGalempsy> got it. thanks tom
[23:00:36] <Tom_itx> np
[23:00:37] <furrywolf> ... emacs is not awesome.
[23:00:46] * alex4nder facepalms.
[23:01:26] <alex4nder> anyone in here using the realtime ethernet control in linuxcnc with a mesa board?
[23:02:05] <furrywolf> not I, but I want to be.
[23:02:28] <alex4nder> it's the route I'm going with with this new stepper build
[23:03:09] <alex4nder> I guess with a preempt_rt kernel
[23:03:10] <furrywolf> I want to switch to one, but I don't have enough money, and I really won't if I actually buy any of this tooling...
[23:03:35] <alex4nder> what are you using right now?
[23:04:13] <furrywolf> a $10 chinese breakout board on a parallel port
[23:04:19] <alex4nder> cool
[23:04:26] <alex4nder> that was like my old setup
[23:08:00] <furrywolf> grrr, that store I pasted has the cheapest prices I could find on a lot of tooling... then I go to check the shipping cost, and it's $34 for 3+ week ground.
[23:08:14] <Cromaglious> heh I tend to use joe
[23:08:18] <furrywolf> whoops, my bad. it's $34 for 6-9 weeks.
[23:08:34] <furrywolf> $37 for 3 weeks
[23:08:39] <Cromaglious> furrywolf, OUCHIES
[23:10:27] <Cromaglious> ahhh ,uch better a working keyboard
[23:14:10] <Cromaglious> whats the total bill?
[23:14:30] <Cromaglious> is it still cheaper than free shipping sites
[23:14:46] <Cromaglious> that's my criteria
[23:15:19] <furrywolf> no, it's higher.
[23:16:11] <furrywolf> bbl, wolfy bedtime
[23:18:43] <furrywolf> http://www.ebay.com/itm/12-5-Rotary-Table-/201287191587 the cheapest rotary table on ebay. lol
[23:18:51] <furrywolf> bbl
[23:22:16] <Cromaglious> that's actually not a bad price on that
[23:22:28] <Cromaglious> would need to rebuild it...
[23:22:49] <furrywolf> would need a machine four times larger to use it...
[23:23:47] <Cromaglious> rebuild it, put pretty paint on it and resell it
[23:24:22] <Cromaglious> free local pickup though
[23:24:43] <Cromaglious> st petersburg, fl
[23:25:41] <Cromaglious> don't know if it's 30 seconds on the dial though
[23:26:02] <Cromaglious> err minutes
[23:26:17] <Cromaglious> that's 720 cranks to go around once
[23:26:35] <furrywolf> lol
[23:26:36] <furrywolf> bbl
