[00:10:07] <JymmmEMC> dmessier: coleman fuel or unleaded gasoline
[00:46:28] <Guest319> Guest319 is now known as skunkworks_
[00:58:44] <dmessier> same thing.. not dual fuel... ive run GALLOOONS of unleaded thru std lanturns and stoves... cat heaters..
[01:00:05] <dmessier> unless you put the Naphta into a gasoline car/truck.... goes like stink..
[01:03:03] <skunkworks_> http://youtube.com/watch?v=Hdhn_j6PrCw
[01:03:22] <dmessier> but only for a while.... burns DRY....
[01:03:46] <skunkworks_> you would think I would figure out how to fix the begining hickup.. but I have not tried
[01:05:27] <dmessier> its ok skunk..
[01:06:03] <dmessier> when GOD made time he made lots of it...
[01:07:25] <dmessier> and dont believe time is $$$.... cause we can all make $$ but NO_ONE can make time.. stop feeding the insanity
[01:08:34] <jmkasunich_> senseless waste really offends me
[01:08:43] <jmkasunich_> we've had two solid days of rain here
[01:08:48] <jmkasunich_> the slow steady deep soaking rain
[01:09:15] <jmkasunich_> what do I see this evening? some dumbass has their underground sprinkler system running
[01:09:15] <jmkasunich_> in the rain
[01:11:41] <jmkasunich_> jmkasunich_ is now known as jmkasunich
[01:12:22] <dmessier> pooo on them... i need 1 day pounding rain to ge things wet
[01:13:59] <dmessier> our rain is rolling thru the few creeks.. (my backyard)..flooding.. aand flushingins
[01:14:30] <dmessier> theres a burp..
[01:16:12] <dmessier> skunk.. thats sweet... ; )
[01:17:13] <skunkworks_> tganks
[01:18:00] <dmessier> thats a cute little sewing machine cnc mill
[01:18:50] <skunkworks_> :)
[01:19:05] <dmessier> seems well built.. ;
[01:20:38] <dmessier> gotta feed me self..
[01:20:48] <dmessier> bbl
[01:58:38] <Serch-Net> Hi, someone can tell me how connect the nas device across iscsi protocol
[01:59:42] <SWPadnos> you're probably looking for the backup/storage software EMC2, not the machine control software EMC2
[01:59:52] <SWPadnos> this is the machinecontrol software channel :)
[02:00:29] <Serch-Net> thanks a lot, sorry, i am some missing
[02:00:54] <Serch-Net> :)
[02:01:49] <jmkasunich> SWPadnos: congrats on being elected!
[02:03:06] <SWPadnos> thanks
[02:03:12] <SWPadnos> you too :)
[02:03:21] <jepler> this makes it all the more important that I actually get a cnc machine and run it with emc
[02:03:36] <jmkasunich> and I need to get off my duff and get my machine working
[02:03:36] <SWPadnos> damn. I thought someone might suggest that
[02:03:37] <skunkworks_> heh - congrats everyone.
[02:03:51] <jepler> skunkworks_: thanks
[02:04:11] <skunkworks_> It looks like it is going to be another great year for emc2
[02:05:03] <SWPadnos> I sure hope so :)
[02:05:08] <SWPadnos> year - or two ;)
[02:05:16] <dmessier> kudos t all
[02:10:03] <skunkworks_> jepler: http://youtube.com/watch?v=Hdhn_j6PrCw
[02:10:44] <skunkworks_> it is 25 in/sec/sec and 200ipm.. although the penguin seems to peak at about 100ipm
[02:16:57] <jmkasunich> ebay item: "Hara-Kiri Knife With Stand (Only Used Once)"
[02:18:38] <skunkworks_> rim shot ;)
[02:18:43] <jmkasunich> (same seller as this nifty XY table) http://cgi.ebay.com/AEROTECH-CNC-X-Y-Motion-Control-Table_W0QQitemZ300078829063QQihZ020QQcategoryZ42899QQcmdZViewItem
[02:20:43] <skunkworks_> he has a few things on ebay
[02:20:53] <jmkasunich> one or two
[02:20:54] <skunkworks_> 429 items
[02:21:15] <SWPadnos> damn. I've said it before and I'll say it again - flat shielded twisted pair cable is expensive
[02:21:38] <jmkasunich> flat unshielded twisted pair is free if you know who to ask ;-)
[02:21:48] <SWPadnos> heh - got some, thatks ;)
[02:21:51] <SWPadnos> thanks
[02:21:59] <jmkasunich> reynolds wrap!
[02:22:06] <jmkasunich> amd duct tape
[02:22:08] <SWPadnos> I may use that first, and get some copper foil tape
[02:22:09] <SWPadnos> heh
[02:23:01] <skunkworks_> that stuff is great (hvac foil tape) - I like it better than duct tape
[02:23:36] <SWPadnos> ouch. $45.40 for a 1" x 18 yard roll of copper tape
[02:31:11] <skunkworks_> night guys
[02:31:15] <jmkasunich> goodnight
[02:31:22] <SWPadnos> good night
[02:31:30] <SWPadnos> I think that's an excellent idea, actually. see you all tomorrow
[02:31:43] <jmkasunich> hmm, I might just make it three
[02:32:04] <jmkasunich> tho the cat in my lap has other ideas
[02:32:10] <SWPadnos> heh
[03:05:33] <ds2> Hmmmmmm
[03:20:02] <cradek> hi all
[03:20:18] <cradek> congrats to those elected to the new board
[04:42:11] <toast> i need a screen in my living room that tells me everything i need to know for the day
[04:42:14] <toast> or maybe a daily printout
[04:42:28] <toast> like, what day it is
[04:42:40] <toast> what classes i have to go to, if there is work
[04:42:43] <toast> chores.
[04:44:11] <toast> i bet that would be an easy thing to do with a database, webapp, and a cron script
[04:44:28] <toast> also, a printer
[04:44:31] <toast> i should get one of those.
[04:57:13] <Noobie1000> Hi, I'm having problems upgrading my ini file to 2.1.7. Can anyone help?
[04:59:34] <Skullworks-PGAB> too early for the night people, too late for the day.
[10:03:59] <fenn> seems there's a lot of controversy over scripting.. didnt expect that
[10:11:27] <alex_joni> different people, different expectations
[10:13:21] <alex_joni> some don't have any real connection to scripting
[11:51:59] <alex_joni> * alex_joni giggles
[11:52:00] <alex_joni> Couldn't contact deer:8010
[11:52:00] <alex_joni> The web interface is down for maintenance.
[12:07:57] <SWPadnos> too many people think their way is "the" way, rather than "a" way ...
[12:08:20] <fenn> i say the more interfaces the better?
[12:08:43] <fenn> fanuc g-code, rs274ngc, python, APT
[12:08:44] <SWPadnos> well, not necessarily that, but at least "the more possibilities, the better"
[12:09:02] <SWPadnos> none of those has anything to do with the script question :)
[12:09:10] <fenn> um, what was the question?
[12:09:30] <SWPadnos> oh wait - python may have to do with it
[12:09:33] <fenn> "how do i make a bolt circle wizard"?
[12:10:07] <SWPadnos> that is related to the script question
[12:10:40] <SWPadnos> but for that, I'd look at holecircle.py ;)
[12:10:54] <fenn> ugh words - me want pointy clicky
[12:11:15] <alex_joni> Gwiz
[12:11:23] <SWPadnos> pointy at ity with the clicky thingy when trying to loady a filey
[12:11:32] <fenn> i just want to be able to program the machine without having to know g-code
[12:11:37] <alex_joni> http://www.se-ltd.com/~lerman/gallery/G-Wiz
[12:11:42] <SWPadnos> that is related to the script question
[12:11:55] <fenn> but if i have to write the scripts, i have to know g-code :P
[12:12:09] <SWPadnos> that is related to the script question
[12:12:11] <SWPadnos> :)
[12:12:15] <fenn> grar
[12:13:15] <SWPadnos> ok - time to make the coffee
[12:13:22] <fenn> maybe i should just forget about it and concentrate on cad/cam
[12:13:45] <fenn> btw inkscape has some nice stuff in it
[12:15:42] <skunkworks> fenn: http://www.youtube.com/watch?v=Hdhn_j6PrCw
[12:16:09] <fenn> booring
[12:16:16] <fenn> lets see it hogging some plexiglass
[12:16:40] <skunkworks> tonight
[12:16:49] <skunkworks> well - not the penguin
[12:16:59] <skunkworks> some sort of image to gcode
[12:17:01] <skunkworks> maybe
[12:17:08] <fenn> it also might be that i've run that program way too many times
[12:17:20] <skunkworks> heh
[12:18:03] <skunkworks> fenn: did you see this one? I think you did (actual cutting) http://www.youtube.com/watch?v=dKz81fY1OjY
[12:18:29] <alex_joni> skunkworks: too bad there were only 5 spots to fill
[12:18:45] <alex_joni> would have liked to have you on the board too
[12:18:55] <skunkworks> alex_joni: all 5 where the best choices. :)
[12:19:20] <fenn> you can still be resident loud-mouth and televangelist :)
[12:19:28] <alex_joni> oh, he sure can do that
[12:19:28] <skunkworks> oh - I plan to be.
[12:19:49] <alex_joni> skunkworks: I would have been happy with any combination from the 7 proposed
[12:21:07] <fenn> skunkworks: milling a circuit board would be a good selling point
[12:22:39] <skunkworks> fenn: I am thinking about it.. but I don't know what I have for tooling that would work for that. I think all the engraver bits are hss. And it is non standard.
[12:23:24] <skunkworks> hmm - I could mount a dremel maybe pretty easy
[12:23:39] <fenn> what bits does it have already?
[12:26:11] <skunkworks> fenn: like this http://cgi.ebay.com/USED-NEW-HERMES-ENGRAVOGRAPH-CUTTERS-LOT-10-ENGRAVING_W0QQitemZ260148980453QQihZ016QQcategoryZ46744QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[12:26:55] <skunkworks> one of these also http://cgi.ebay.com/Hermes-diamond-tip-engraving-cutter_W0QQitemZ140145021741QQihZ004QQcategoryZ26245QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[12:28:19] <fenn> 0.015" isnt small enough eh
[12:30:03] <skunkworks> It would be - I guess. I just don't know how long it would last
[12:30:17] <skunkworks> would it last thru 1 board?
[12:30:40] <skunkworks> I have had bad luck with hhs and fiberglass
[12:30:47] <fenn> hm
[12:30:56] <fenn> you dont have a lathe do you?
[12:31:07] <fenn> well, nevermind that's kinda overkill
[12:31:27] <fenn> i was thinking you could drill a hole in the end of a rod and glue in a dremel bit
[12:31:54] <fenn> time to fire up the gingery mill
[12:32:45] <fenn> 11/64 shaft sounds about right
[12:34:30] <skunkworks> I could probably make up a wood bracket to mount a dremel pretty quicl
[12:34:40] <fenn> that wouldnt be as cool though
[12:34:49] <fenn> nor representative of the machine
[12:35:09] <fenn> you're selling a lifestyle, man
[12:36:39] <skunkworks> heh
[12:39:16] <skunkworks> I probably have some 11/64 drill rod. I could drill a hole as you say and mount a circuit board milling bit in it.
[12:42:03] <skunkworks> I suppose .023" isn't enough room for a setscrew. ;)
[12:42:39] <skunkworks> a brass ring around it at the bottom for a setscrew would work I bet
[12:44:06] <fenn> why not splurge and make a spring collet :)
[12:44:11] <skunkworks> heh
[12:44:50] <fenn> i'd be worried that a setscrew would push it off center
[12:44:55] <skunkworks> When I had plans to keep it - I was going to make a different spindle for it. That would have been something will a collet.
[12:45:13] <skunkworks> the spindle comes out with 2 setscrews I think.
[12:45:29] <skunkworks> with a collet
[13:37:45] <jepler> * jepler grumbles -- still no shipping notification for his new cnc router
[13:39:27] <SWPadnos> on a happier note, I got my openmoko :)
[13:39:38] <jepler> have you gotten it to do anything yet?
[13:39:39] <SWPadnos> but no shipping notification from Mesa
[13:39:45] <SWPadnos> it almost boots
[13:39:58] <SWPadnos> and has a very high resolution screen - the boot console messages are about 3-point
[13:40:24] <jepler> is this for a particular project, or just because it sounds cool?
[13:40:36] <SWPadnos> kind of both
[13:41:10] <SWPadnos> I like supporting open source projects when I can, plus I have a customer who wants some remote monitoring apps that could benefit from cell technology
[13:42:25] <fenn> well its cheaper than an airplane
[13:42:32] <SWPadnos> significantly so
[13:42:43] <SWPadnos> even a model airplane would get more expensive
[13:43:04] <fenn> after crashing it twenty times maybe
[13:43:37] <SWPadnos> well, once you throw in a high performance motor and driver (and battery), nice remote control unit, several servos ...
[13:43:46] <SWPadnos> a paper airplane would be much less expensive
[14:43:07] <cradek> skunkworks: nice video of cutting chips in the air
[14:43:19] <cradek> the machine seems really snappy
[14:45:49] <cradek> I've made tool holders for small tools out of brass. In the lathe turn the outside and drill the end in the same mounting, put a bit of shellac in the hole, warm it with a flame, put the tool in, and let it harden while keeping it centered (touch the tool with a peg against the tool rest while the work is rotating)
[14:46:13] <cradek> it doesn't matter if the hole is too big (made with a full size 1/8 drill bit)
[14:48:30] <cradek> it's a watchmaker trick to center parts for turning: put a piece of brass in a collet, catch the center and make a dent the right size, fill with shellac, center the part while it hardens
[14:48:48] <skunkworks> cradek: neat
[14:49:10] <cradek> for engraving PCBs it would be plenty strong
[14:49:32] <cradek> I did it for using regular drill bits in my 1/8 collet: just make one for each drill bit (drill with the bit itself, then reverse it and shellac it in)
[14:50:20] <skunkworks> yes - that should work great
[14:50:43] <jepler> hm, I think I was running my crappy little motor at twice the rated current with the xylotex. I didn't see the note: "When Setting Vref for a UNIPOLAR rated motor, use a current of 50.0% of the rated unipolar current, when wired for series mode."
[14:50:53] <skunkworks> I think I may have to do a milling of a circuit board..
[14:50:54] <jepler> no wonder it got so hot after an hour with the amp on
[14:51:40] <jepler> the faceplate says "3.6 ohm 5V 1.36A
[14:51:53] <jepler> " and the resistance from center tap to end of winding measured about 3.6 ohm ..
[14:52:51] <jepler> Using higher current can "smear microstepping smoothness and accuracy", according to the pd
[14:52:56] <jepler> f
[14:53:02] <cradek> http://www.tp178.com/jd/watch-school/3/staff-on-lathe.jpg
[14:53:05] <skunkworks> heh - I have heard a bit of different 50% or .707 of rated current
[14:53:54] <cradek> hahaha http://www.tp178.com/jd/watch-school/3/double-decker-staff-0034.jpg
[14:54:31] <skunkworks> yikes - I would shake and break it right of..
[14:54:41] <jepler> if you so much as sneeze, that'll snap
[14:54:50] <jepler> *achoo* damn
[14:54:59] <cradek> notice the collet is 2-something (2.x mm)
[14:56:30] <skunkworks> I would use epoxy 5 min (it is what I have)
[14:57:47] <cradek> I wonder if you can get chip shellac at a hardware store
[14:58:22] <cradek> with shellac if it takes you a few tries to get it centered, no problem
[14:58:33] <cradek> epoxy is kind of a commitment
[14:59:01] <archivist> just dont overheat the shellac
[14:59:13] <cradek> yeah it should be just soft
[14:59:14] <skunkworks> these are all 1/8 shank - I would think I could ream it to a slip fit
[14:59:27] <skunkworks> for this purpose
[14:59:31] <cradek> I bet archivist has done this a few times too :-)
[14:59:35] <skunkworks> heh
[15:00:06] <archivist> cradek actually only doing rollers etc
[15:00:23] <cradek> you don't reverse a balance staff this way to turn the other side?
[15:00:39] <archivist> no turn it in one
[15:00:54] <cradek> you're better at it than me then
[15:01:10] <cradek> (no big surprise there)
[15:03:35] <fenn> hot glue gun
[15:04:14] <archivist> I have used broken carbide pcb drills to make gravers for turning small stuff
[15:06:28] <fenn> how do you sharpen stuff that small?
[15:06:49] <archivist> hard work, and try again
[15:07:07] <archivist> often wrong first time round
[15:07:38] <cradek> diamond paste?
[15:08:07] <fenn> thats what google sayz
[15:08:09] <archivist> when turning up a small pinion I can often go through a number of resharpens
[15:09:45] <archivist> when hand turning with a graver though you just rotate/move the tool for a better edge
[15:10:03] <fenn> so its not shaped like a lathe bit?
[15:10:31] <archivist> no
[15:11:09] <cradek> http://www.engravingarts.com/jpgs/squareGraver.jpg
[15:11:10] <fenn> does anyone use EDM in watch making?
[15:11:18] <cradek> fenn: yes lots
[15:12:07] <cradek> fenn: a traditional graver is square cross section with the business end ground and sharpened at an angle to make a diamond
[15:12:57] <fenn> i was thinking about making a qctp holder for that type of bit
[15:16:53] <skunkworks> hmm the machine shop here doens't have 11/64 drill rod
[15:25:02] <skunkworks> fenn: I make a few engraver bits for pcb milling before I bought the thinktink bits.
[15:27:08] <skunkworks> I would put the broken carbide in one dremel and a diamond wheel in the other. I would turn both on to make the carbide into a point - then dremel off that had the carbid in it and grind half of the carbide away to the point. Then releave it around the outside edge.
[15:27:46] <skunkworks> it worked ok - but the bits from thinktinker work so much nicer\
[15:29:59] <fenn> skunkworks: how bout drilling a hole in the back of one of the bits you've got?
[15:30:30] <skunkworks> I don't know how hard they are. (if they are hard the whole way.
[15:30:34] <skunkworks> )
[15:30:37] <skunkworks> maybe
[15:31:16] <fenn> carbide drill ;)
[15:31:57] <skunkworks> heh.
[15:32:03] <fenn> heh you could make a carbide gun drill from a broken bit pretty easily
[15:32:37] <skunkworks> I actually probably have 1/8 carbide drills. I would have to look
[15:33:00] <skunkworks> what does a gun drill look like?
[15:33:48] <fenn> i guess i meant "straight fluted drill"
[15:34:35] <archivist> often with a hole down it for lube
[16:02:57] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[16:30:18] <fenn> anyone remember xeyes? http://www.motionportrait.com/e/about/TIminoriHair.swf
[16:41:34] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[16:57:23] <skunkworks> fenn: that is just freaky
[17:06:13] <Noobie1000> Hi, I'm having problems updating my ini file to 2.1.7: the machines moves extremely slowly and I get the message: STEPGEN Channel 0: The requested velocity of 28000 steps/sec is too high.
[17:08:06] <skunkworks> could you pastebin.ca your ini?
[17:10:10] <Noobie1000> It is here. It is a modified version of stepper xyza: http://pastebin.ca/665824. Thanks for the help
[17:11:03] <Noobie1000> I am trying to update it with the values from http://www.sherline.com/emc/mill_mm_freq.txt, which is for an older version of emc.
[17:11:51] <Noobie1000> My A axis is working fine, I just need to fix the xyz.
[17:14:04] <skunkworks> ok - looks like they were running a base period of 20000 - can your machine do that?
[17:15:06] <skunkworks> the maximum steps per second you can run right now with the baseperiod set to 50000 is 10000 which is 12.5 mm/sec
[17:15:15] <Noobie1000> I'm sorry I don't understand your question. The machine is a normal Sherline mill.
[17:15:29] <skunkworks> sorry.
[17:15:40] <skunkworks> what kind of computer is this on?
[17:15:47] <fenn> 20000 is doable on most any computer
[17:16:01] <fenn> if not, the machine locks up anyway
[17:16:18] <Noobie1000> I have an AMD64 laptop (Acer Ferrari) running i386 ubuntu
[17:16:24] <fenn> is it a units problem? did you switch from inch to mm somewhere?
[17:16:44] <fenn> MACHINE = EMC-HAL-STEP-XYZA-IN
[17:17:04] <fenn> i dont think that does anything but it implies that you started off with an inch-based config file
[17:17:15] <Noobie1000> ITs a mm machine but the only xyza config I found was inch. Either way, the settings are wrong
[17:18:19] <skunkworks> it looks like most is correct - try BASE_PERIOD = 20000
[17:18:25] <skunkworks> for now
[17:18:33] <Noobie1000> thank you
[17:19:31] <fenn> i thought there was some kind of warning dialog that calculated this stuff for you
[17:19:53] <skunkworks> <Noobie1000> Hi, I'm having problems updating my ini file to 2.1.7: the machines moves extremely slowly and I get the message: STEPGEN Channel 0: The requested velocity of 28000 steps/sec is too high.
[17:21:19] <fenn> right. the old behavior was just "following error" i think
[17:21:40] <Noobie1000> I still get the same error with BASE_PERIOD = 20000
[17:21:48] <skunkworks> Noobie1000: also lower your max velocity to 30
[17:22:55] <skunkworks> I should say - how fast do you want to go?
[17:22:59] <skunkworks> mm/min?
[17:23:15] <skunkworks> * skunkworks isn't a metric person
[17:23:31] <Noobie1000> the velocity change didin't do anything either
[17:23:47] <skunkworks> hold on
[17:28:00] <Noobie1000> Sunkworks thank you, it kind or works, now. I still get the error, but the axis are moving at the proper rate.
[17:28:52] <skunkworks> hold on
[17:29:30] <skunkworks> http://pastebin.ca/665842
[17:30:25] <skunkworks> axis0 did have a few problems..
[17:30:59] <skunkworks> MAX_ACCELERATION = 15
[17:31:05] <skunkworks> STEPGEN_MAXVEL = 10.00
[17:31:11] <skunkworks> STEPGEN_MAXACCEL = 20.0
[17:31:18] <skunkworks> MAX_VELOCITY = 8
[17:31:22] <skunkworks> should work
[17:33:18] <Noobie1000> Your new file works great.
[17:33:23] <Noobie1000> Thank you
[17:33:26] <skunkworks> Great !
[17:34:11] <skunkworks> where you using emc1 up to this point?
[17:37:15] <Noobie1000> The Sherline machine is "new" I didn't play with the bundled EMC version much, and so I tried to upgrade right away.
[17:37:38] <skunkworks> nice - I am sure you will like the axis interface.
[17:38:38] <Noobie1000> Its definitively much better than the old one. I wouldn't go back. Would it be hard to get the ini files for basic Sherline machines in CVS?
[17:39:44] <Noobie1000> Maybe I can post mine on a wiki somewhere
[17:40:07] <skunkworks> That would be great.. (I am not a developer)
[17:40:29] <fenn> i thought the default stepper configs were for sherlines
[17:40:53] <cradek> Noobie1000: do you have the sherline A axis?
[17:41:01] <Noobie1000> The INPUT_SCALE is wrong
[17:41:19] <Noobie1000> Yes, I have the Sherline CNC rotating table
[17:41:41] <cradek> I think it would be great to get a perfect sherline XYZA configuration in the future releases
[17:42:10] <Noobie1000> I would be happy to help with this.
[17:42:11] <cradek> without having one of those it's hard to guess what the proper accel/velocity are
[17:42:45] <cradek> that's great. when you are happy with it, you can send it to me, or any other developer, or put it on the wiki, etc
[17:43:37] <Noobie1000> OK, will do. However, I think I can only provide a mm version (for XYZ) because my machine is metric.
[17:45:17] <skunkworks> It should not matter.. I assume they use the same machine be it metric or english.
[17:45:37] <skunkworks> (I could be wrong)
[17:47:34] <cradek> I know you can get either leadscrews. I don't know if they use different screws for their cncs though.
[17:47:50] <cradek> Noobie1000: with EMC2 you can run inch or mm gcode equally well, just put G20 or G21 at the top of your program
[17:48:02] <cradek> I have a metric lathe but often (usually?) use inch gcode
[17:55:02] <ds2> does it matter what kind of lead screw is on a CNC lathe?
[17:55:21] <Noobie1000> From the docs: The difference between inch and metric models of the lathe and mill are not just the handwheel markings, but include the leadscrews, nuts, inserts, handwheels and tailstock spindle.
[17:55:22] <SWPadnos> only for accuracy. EMC doesn't care
[17:55:29] <cradek> not really.
[17:55:38] <Noobie1000> The handwheel on the inch models moves the slide .050" per revolution and has 50 graduations of .001". The metric model moves the slide 1mm (.03937") per revolution and the handwheel is graduated into 100 divisions.
[17:56:20] <SWPadnos> Noobie1000, it seems cleaner to define the machine as inch or mm based on screw pitch, but it really has about zero effect
[17:56:23] <ds2> any opinions of lube for an unknown manufacture ball screw?
[17:56:37] <SWPadnos> the main difference is whether you get an integer number of steps per unit
[17:56:47] <cradek> Noobie1000 could configure his machine in inch, his scales would be strange numbers (not integers), but EMC doesn't care
[17:57:37] <skunkworks> Noobie1000: did you say your input scale was wrong? (800)
[17:57:59] <skunkworks> sounds like metric 1/4 stepping
[17:59:22] <jepler> " · 800 steps per revolution (microstepping), equates to 16,000 steps/inch with .050" pitch leadscrew" -- sherline.com
[17:59:44] <skunkworks> I thought he had a metric machine - one turn per mm
[18:00:07] <jepler> yeah, I am just confirming that it's 800 steps per revolution
[18:00:16] <Noobie1000> I am confused: if I try to create an inch.ini file for my machine, it won't work with the Sherline inch model, since the pulse won't generate the same displacement.
[18:00:48] <cradek> your scale would be different, that's all.
[18:00:57] <cradek> but there's NO reason to have two configurations for your machine.
[18:00:58] <jepler> so for a 1mm screw it's SCALE 800 for a mm inifile and SCALE 20320 for an inch inifile
[18:01:12] <jepler> (if I did my math right)
[18:01:57] <jepler> emc2 foam cutting pics: http://i14alberta.ca/gallery2/main.php?g2_itemId=1014
[18:03:25] <cradek> whee
[18:03:36] <Noobie1000> You are right, cradek. I only need one file, but I would have liked to provide a Sherline config for both metric and inch models.
[18:05:02] <cradek> oh I understand now, sorry
[18:16:21] <Noobie1000> Should I use TASK = minimilltask (instead of milltask) for a Sherline mill?
[18:16:30] <cradek> no
[18:16:37] <cradek> that's old emc1 advice
[18:16:35] <Noobie1000> thanks
[18:19:40] <skunkworks> Noobie1000: you haven't gotten any realtime latency errors on your portable?
[18:27:40] <skunkworks> cradek: any manuals for the bridgeport?
[18:28:01] <cradek> still no.
[18:28:17] <skunkworks> darn
[18:28:40] <cradek> the mesa parts will be a while anyway.
[18:29:09] <cradek> steve stallings said he can copy the manuals for me. he's been a huge help already.
[18:29:24] <skunkworks> he seems like a nice guy.. ;)
[18:29:27] <cradek> meanwhile, the machine is working with only minor quirks now.
[18:29:57] <skunkworks> did you fix anything or has running it helped? Plugged/unplugged card
[18:29:59] <cradek> switching the X and Z amps caused the occasional amp fault to go away (!?)
[18:30:09] <Noobie1000> I didn't get latency errors yet. But my Y and Z axis seem to be inverted.
[18:30:18] <cradek> Noobie1000: negate the scale
[18:30:34] <skunkworks> inputscale
[18:30:34] <Noobie1000> The INPUT_SCALE?
[18:30:38] <skunkworks> yes
[18:30:49] <cradek> skunkworks: also, it forgets/trashes the saved program and tool table when it's turned off, although I tested the batteries and they are OK.
[18:31:01] <skunkworks> yeck
[18:31:09] <cradek> it's easy to reupload it though.
[18:31:30] <skunkworks> oh - so you can upload them serialy?
[18:31:48] <cradek> yes you can upload the gcode with a serial port
[18:31:55] <cradek> there are a few contortions but not bad
[18:32:30] <cradek> it has a (very basic) line editor that you can run with a serial terminal. So with care you can use it to "type in" the program.
[18:37:24] <skunkworks> cool
[18:38:57] <skunkworks> that will do a lot of work for you.. You just need to figure out what ;)
[18:40:20] <skunkworks> are you thinking of using the existing servo amps? and how annoying are they?
[18:40:44] <skunkworks> I have heard they have a pretty low switching frequency
[18:40:59] <cradek> they perform OK but are very loud
[18:41:10] <cradek> yes I'll surely use them
[18:41:47] <skunkworks> that is what earplugs are for ;)
[18:42:06] <cradek> it's drowned out by the phase converter, air compressor, and (of course) spindle motor
[18:42:24] <skunkworks> keep an eye on ebay - I am sure you could get the amps pretty cheap
[18:42:32] <skunkworks> for spares
[18:42:51] <cradek> I bet Jon E has some too
[18:42:57] <skunkworks> not that they would be pretty hard to fix
[18:47:28] <skunkworks> I found the R key yesterday..
[18:47:35] <skunkworks> ;)
[18:47:49] <skunkworks> * skunkworks is a point and clicker..
[18:48:05] <cradek> r?
[18:48:09] <cradek> oh, run?
[18:48:11] <cradek> ha
[18:48:13] <skunkworks> yah
[19:16:55] <skunkworks> cradek: the email from watchman1 - I have seen that happen in 2.1.7. I have not really looked into it.
[19:17:27] <skunkworks> I figured it was a g10 offset (must have been in there from the get go)
[19:19:32] <cradek> I have not seen that problem... need more information to reproduce it.
[19:20:52] <alex_joni> yay foam cutting
[19:22:12] <skunkworks> It was a fresh isntall updated ubuntu emc2. When selecting the stepper_inch.ini and you go and home each axis - one or more do not 0 - they actually change to some non-zero number. (installed 2.1.7)
[19:22:31] <skunkworks> (I had actually thought it was me)
[19:23:00] <skunkworks> wondering if the var file in the installed 2.1.7 stepper_inch.ini has offsets in it.
[19:23:10] <cradek> ah that could be...
[19:23:14] <skunkworks> for g54
[19:23:36] <skunkworks> I had cleared the g92 offsets but didn't change anything.
[19:24:40] <alex_joni> HAHAHA
[19:24:47] <alex_joni> "E-stop
[19:24:48] <alex_joni> ring tones would be nice too. "
[19:24:57] <jepler> huh?
[19:25:12] <lerman> skins
[19:25:35] <cradek> I think it's insulting to machinists to think we have to rearrange the buttons to match a control they already know.
[19:26:02] <cradek> for instance, I can be pretty sure that someone who is used to an R2E3 might like an incremental jog other than .0001"
[19:26:30] <cradek> I just don't see "the emc interfaces are bad, commercial interfaces are good"
[19:27:15] <cradek> sorry, am I trolling?
[19:27:41] <cradek> maybe all user interfaces suck, it's just that they all suck differently, and you can get used to any particular kind of suckage.
[19:27:41] <alex_joni> jepler: Kirk's latest email
[19:28:05] <alex_joni> lerman: did you just unsubscribe from emc-commit?
[19:28:54] <lerman> I don't think so. I was deleted because my email was down at some point. And I never go around to figuring out how to resubscribe.
[19:29:30] <lerman> got
[19:38:01] <alex_joni> I got an email about 2 hours ago that you have been unsubscribed from emc-commit
[19:38:09] <alex_joni> I'll put you back on the list
[19:38:23] <lerman> thanks
[19:38:26] <alex_joni> lerman-emc AT se-ltd DOT com ?
[19:38:40] <lerman> yup.
[19:39:34] <JymmmEMC> lerman-emc AT IGotDeletedAndAmNoMore [dot] se-ltd DOT com
[19:40:38] <lerman> Well, I *could* add that to my name server -- but it would take a while to propagate.
[19:40:50] <JymmmEMC> lerman: 48hours max
[19:41:11] <JymmmEMC> lerman: just set TTL=300
[19:41:21] <lerman> But I would miss some more commits in that time.
[19:41:47] <JymmmEMC> like you havne't already missed months worth, whats 48 hours
[19:42:10] <lerman> It depends. I don't know what will be committed.
[19:42:25] <JymmmEMC> it really won't matter
[19:42:36] <skunkworks> JymmmEMC: http://www.youtube.com/watch?v=Hdhn_j6PrCw
[19:42:42] <JymmmEMC> not like 0Day commits or anything
[19:42:50] <JymmmEMC> skunkworks: what is it?
[19:44:28] <JymmmEMC> skunkworks: oh, so you're keeping it? Or flacking off again and want to get your garage paid for?
[19:44:32] <JymmmEMC> -c
[19:52:30] <cradek> skunkworks: your penguin test sometimes sounds like C3PO
[19:54:22] <skunkworks> JymmmEMC: I figure it will sell better with a few videos
[19:54:41] <skunkworks> cradek: :)
[19:56:13] <jepler> cradek: hm, that surplus center enclosure might be tall enough, the power supply (tallest thing in the box) is 1.66", the box is 2 1/8 inside
[19:56:41] <cradek> it looks like it's meant for mounting on a wall - not sure how "friendly" it would be to a desk etc
[19:56:52] <jepler> that's true
[19:57:29] <jepler> and the power supply is just a little too long to fit in the short dimension, so it would use up 3.9" out of 7.125"
[19:57:31] <jepler> back to thinking it's too small
[19:57:34] <JymmmEMC> skunkworks: oh, just keep it already. ya know you want to.
[19:57:51] <cradek> he actually wants to just send it to me
[19:59:23] <skunkworks> heh
[20:09:09] <alex_joni> I bet he prefers shipping to europe
[20:12:10] <jepler> cradek: when you say you're looking for a small LCD, do you mean under 15"?
[20:12:53] <alex_joni> 4-5", 1600x1200
[20:13:05] <alex_joni> lerman: you should be back on track now..
[20:13:14] <alex_joni> lerman: let me know if you have additional problems
[20:13:23] <cradek> yes, even a 10" or so 800x600 would be great
[20:13:45] <jepler> so like this but not an arm and a leg: http://www.dgahouston.com/monlcd10.htm
[20:14:04] <cradek> ouch ouch ouch
[20:14:13] <cradek> yeah that would be great.
[20:14:47] <cradek> there are a lot of them on ebay that are for cars, but I doubt they take vga and just work
[20:15:41] <jepler> yeah -- I think that composite input (and resolution more like 640x480) is most likely
[20:15:55] <cradek> ooh the $521 version has a touch screen. that would be so cool.
[20:17:09] <cradek> I do have a 9" 800x600 monitor. Maybe I can mount that somehow.
[20:17:27] <cradek> not sure which is easiest to see in bright light
[20:18:02] <jepler> if it was in stock: http://www.mini-box.com/VM1040-10-4-LCD-touchscreen-monitor?sc=8&category=101
[20:18:59] <cradek> I'm too cheap :-(
[20:19:05] <cradek> even at $350

[20:25:14] <skunkworks> sorry - under 10"
[20:26:26] <JymmmEMC> SWPadnos: Strike #2
[20:26:37] <SWPadnos> bummer
[20:26:52] <JymmmEMC> SWPadnos: Let's get ready to rumble!!!! FOIA
[20:27:06] <SWPadnos> oooohhh :)
[20:27:52] <SWPadnos> but remember - the redacting magic marker they use is very very wide
[20:35:44] <cradek> I bought the SHK1040, thanks everyone
[20:35:55] <alex_joni> good deal
[20:35:56] <alex_joni> :P
[20:36:29] <skunkworks> 'let the conversion begin..'
[20:39:51] <lerneaen_hydra> how's linux support with touchscreens?
[20:40:06] <alex_joni> most are simple HID devices
[20:40:13] <alex_joni> just like a mouse
[20:40:16] <lerneaen_hydra> oh
[20:40:25] <alex_joni> at least some I've seen
[20:40:27] <lerneaen_hydra> they appear as a mouse to the computer?
[20:40:31] <alex_joni> yup
[20:40:39] <lerneaen_hydra> don't mice have relative position adressing?
[20:41:00] <alex_joni> that's why you have a controller in there ;)
[20:42:00] <alex_joni> I know some older serial touchscreens sometimes had some strange protocol
[20:42:11] <lerneaen_hydra> no, I mean't the way that data is sent over the usb/ps2 interfave
[20:42:14] <lerneaen_hydra> inteface
[20:42:24] <alex_joni> but it would be incredibly stupid to invent some strange USB stuff
[20:42:40] <lerneaen_hydra> I wouldn't be surprised
[20:47:41] <lerneaen_hydra> is there any common reason for insanely long latencies with non-RT inputs? like 1s delays on the keyboard?
[20:55:58] <skunkworks> I could see with a a really low base_period anything non realtime could be a crapshoot
[20:56:53] <lerneaen_hydra> my base period isn't very low though
[20:57:03] <alex_joni> lerneaen_hydra: only when emc is running?
[20:57:08] <lerneaen_hydra> typically latency is 20µS, base period is around 40µS
[20:57:18] <lerneaen_hydra> alex_joni; hmm, I don't know actually
[20:57:25] <lerneaen_hydra> I always run emc on that computer :p
[20:57:42] <alex_joni> well.. I'd try that first ;)
[20:57:44] <lerneaen_hydra> I only notice it when jogging
[20:57:57] <alex_joni> hmm.. might be low accel settings?
[20:58:01] <lerneaen_hydra> the thing is I've had the same behavior on another EMC machine
[20:58:04] <robin_sz> meep?
[20:58:08] <lerneaen_hydra> nah accel is around 200mm/s²
[20:58:30] <lerneaen_hydra> and the latency is intermittant
[20:58:50] <lerneaen_hydra> sometimes it's not noticable
[20:58:55] <alex_joni> robin_sz: dude
[20:59:04] <robin_sz> alex_joni: :)
[20:59:22] <lerneaen_hydra> I'm not sure but it seems that the latency doesn't change while the computer is running
[20:59:29] <lerneaen_hydra> it only changes between boots
[20:59:50] <alex_joni> that's odd
[20:59:52] <alex_joni> and strange
[21:00:03] <lerneaen_hydra> yeah
[21:00:04] <alex_joni> and peculiar even
[21:00:06] <lerneaen_hydra> very much so
[21:00:18] <lerneaen_hydra> so much that it's probably an error on my end
[21:00:20] <lerneaen_hydra> *?
[21:01:07] <alex_joni> who knows?
[21:01:18] <alex_joni> wth is a subneck?
[21:01:36] <cradek> I don't know that word
[21:02:20] <alex_joni> that's odd.. watching some tv show, and they use that word
[21:02:36] <cradek> what context?
[21:03:36] <lerneaen_hydra> maybe subneck as in sub-neck, as in below the neck?
[21:03:42] <alex_joni> I think the original (english) word is Unsub
[21:03:50] <alex_joni> Unknown Subject
[21:03:54] <cradek> I don't know that word either...
[21:04:02] <alex_joni> http://en.wikipedia.org/wiki/Unsub
[21:04:08] <alex_joni> wikipedia does though
[21:04:19] <alex_joni> the show is actually criminal minds.. so that fits
[21:13:02] <skunkworks> I didn't know the word until the show 'criminal minds' they always call the unkown serial killer the 'unsub'
[21:13:36] <skunkworks> heh - I didn't read alex_joni comment
[21:13:48] <alex_joni> :P
[21:13:55] <alex_joni> skunkworks: you were correct
[21:14:03] <alex_joni> 23:46 < skunkworks> I will shut up now. sorry. I don't think I am all here
[21:14:03] <alex_joni> today
[21:14:11] <skunkworks> heh
[21:15:33] <robin_sz> I was just looking at some very interesting combined axis technology
[21:16:18] <robin_sz> imagine a big gantry in X
[21:16:27] <robin_sz> and a reasonably light/fast Y axis
[21:16:48] <robin_sz> Y can manage reasonable accels (1, 1.5G )
[21:17:02] <robin_sz> X cant, so you have to slow the whole thing down to 0.5G or so
[21:17:22] <alex_joni> * alex_joni says rotate the part when needed
[21:17:39] <robin_sz> * robin_sz points to the 3m x 1.5m sheet
[21:17:48] <alex_joni> heh, that reminds me
[21:17:53] <robin_sz> so you add an extra sub X axis ..
[21:17:59] <robin_sz> 300mm travel
[21:18:03] <alex_joni> seen a nice turn/tilt table when I was in germany recently
[21:18:15] <alex_joni> 100.000N turn/tilt
[21:18:29] <alex_joni> plus 2m vertical axis to move the whole table up/down
[21:18:29] <robin_sz> that does small moves .. and starts off bigger moves, the main axis catches up when it can
[21:18:48] <alex_joni> robin_sz: that's exactly like Till's emc controlled machine
[21:18:48] <robin_sz> coo
[21:18:49] <skunkworks> there was a video someone had on here that had something similar - a small fast axis parrallel to the slow larger axis.
[21:18:57] <alex_joni> he called it a mixer I think
[21:19:16] <skunkworks> alex_joni: do you know where the video is?
[21:19:35] <alex_joni> http://audiflitzer.de/mixer.html
[21:20:13] <alex_joni> skunkworks: was that fast enough?
[21:20:39] <skunkworks> nic
[21:20:41] <skunkworks> nice
[21:20:55] <skunkworks> you're the link master :)
[21:21:33] <alex_joni> sometimes people say I have a good memory
[21:23:30] <skunkworks> I don't have that problem..
[21:30:51] <skunkworks> bbl
[21:32:36] <robin_sz> right, interesting arangement
[21:34:25] <alex_joni> heh
[21:34:29] <alex_joni> * alex_joni goes to bed
[21:34:31] <alex_joni> good night all
[21:34:57] <robin_sz> night
[21:35:13] <robin_sz> damn, my interenet is sooooo sloooooow
[21:35:28] <alex_joni> get minitel
[21:35:38] <robin_sz> yeah?
[21:35:48] <ds2> 4800bps access over GSM dialup?
[21:35:53] <robin_sz> barely getting 10mb down this ADSL wire
[21:36:13] <anonimasu> :/
[21:36:21] <anonimasu> robin_sz: im only getting 24 :/
[21:36:40] <robin_sz> yeah, its crap isnt it
[22:10:13] <JymmmEMC> robin_sz: 10Mb? or 10Kb ?
[22:16:36] <dmessier> High all... another boss bites the dust...
[22:16:46] <anonimasu> ?
[22:17:30] <dmessier> my boss got walked outta tthe building at lunch time...
[22:17:45] <robin_sz> heh
[22:17:54] <robin_sz> child porn or coccaine abuse?
[22:18:30] <dmessier> one a my equals this am is a director this afternoon
[22:18:43] <dmessier> i doubt either..
[22:19:19] <dmessier> our company has PROGRAMS for those ppl... we have them... that many...
[22:20:38] <robin_sz> programs for coccaine abusers?
[22:21:19] <dmessier> changing of the guard...we've turned the bot around at this company 2x 360 degrees...and the captain is lookin for a full moon in broad daylight...
[22:22:01] <robin_sz> mmmm .. that probabl means something to you, but not to me
[22:22:15] <dmessier> yes.. you wont lose your job over it .. show up with union rep and off to rehab.. on 65% wages i believe
[22:22:25] <robin_sz> coo
[22:22:53] <dmessier> the company tries... but too many abuse...
[22:23:38] <robin_sz> well, if it keeps them happy
[22:23:45] <dmessier> join... train.. get clean.. piss off....
[22:23:57] <robin_sz> software?
[22:24:31] <dmessier> IT department that slower than molasses in January..
[22:25:07] <dmessier> alot of old x_nix code to maintain..
[22:25:24] <dmessier> piped thru win_blows
[22:25:29] <robin_sz> yeuw
[22:25:56] <dmessier> it isnt pretty... serial server connection.. honest
[22:26:03] <robin_sz> nice
[22:26:34] <robin_sz> cobol?
[22:27:35] <robin_sz> or nothing quite that modern?
[22:27:52] <dmessier> that for the MRP ( manufacturing resources planing ) software only.. more fortran like as i recall... i hached a few query progs to see why they would take so long to build
[22:28:38] <dmessier> mid '80s ish s'ware
[22:29:13] <dmessier> the place was unix before that..
[22:50:26] <tomp> where's the python path?
[22:53:19] <tomp> got it
[23:22:08] <archivist> whats the data rate that the parport can achieve
[23:36:27] <Guest783> Guest783 is now known as skunkworks_
[23:38:25] <cradek> hi Adam
[23:38:52] <Adam> Hello, does anybody have exp. with converting an anilam crusader M to EMC2?
[23:38:58] <Adam> hey
[23:39:37] <cradek> what is it?
[23:39:51] <skunkworks_> jepler: before I try it (or find a picture) do color pictures work ok?
[23:39:59] <skunkworks_> for image to g-code
[23:40:45] <Adam> the machine is a knee mill, it already has servos and scales installed.
[23:40:55] <jepler> skunkworks_: it's not hard to try it :-P
[23:40:58] <skunkworks_> jepler: cool program (first time I have used it)
[23:41:07] <jepler> skunkworks_: if I was thinking properly I would have automatically converted a color image to greyscale
[23:41:07] <skunkworks_> heh
[23:41:17] <skunkworks_> ok
[23:41:29] <cradek> Adam: ah I see. I don't know of anyone doing that particular machine, but there are lots of knee mills running EMC.
[23:41:36] <cradek> is there anything special or unusual about it?
[23:41:54] <Adam> nothing I am unsure of the electronics side thats all
[23:41:58] <skunkworks_> jepler: thanks
[23:42:15] <Adam> the boards I would need to purchase and configure for example
[23:42:21] <cradek> Adam: does it have encoders or resolvers on the motors?
[23:42:37] <Adam> it has tacho's on the motors
[23:42:45] <Adam> scales on the table
[23:42:46] <cradek> there are quite a few options for what hardware can be used to drive it
[23:42:55] <cradek> oh, no motor encoders at all?
[23:42:56] <Adam> no
[23:43:20] <cradek> interesting, is it really tight or is there some backlash?
[23:43:39] <skunkworks_> jepler: is the convert to arcs working in trunk
[23:43:40] <cradek> Adam: http://www.anderswallin.net/2007/08/dah-lih-emc2-conversion/
[23:43:41] <Adam> its tight,
[23:43:59] <Adam> the anilam control is using the scales as feedback
[23:44:03] <cradek> here is a recent new conversion of a knee mill done for daily use in a machine shop
[23:44:07] <Adam> so the table has feedback
[23:44:54] <cradek> do the tachs hook right to the amps, or to the control?
[23:45:06] <Adam> to the amps
[23:45:24] <cradek> ok so the control pid is just a position loop still, that's good for EMC
[23:45:31] <skunkworks_> do you know what the amp takes for input? +/-10v for example?
[23:46:48] <Adam> I dont know that yet
[23:47:10] <skunkworks_> are the amps separate from the actuall controller?
[23:47:22] <Adam> yes
[23:47:30] <jepler> skunkworks_: I think so, not sure
[23:48:03] <skunkworks_> that is good. Your going to have to know what kind of signal your amps take and what type of signal the scales output like quadture.
[23:48:15] <skunkworks_> jepler: I may try it :)
[23:48:45] <skunkworks_> jepler: the last I has seen is you had disabled it.
[23:49:03] <cradek> you will need hardware to count the quadrature from the scales. We have several supported interfaces, depending on whether you want PCI or parport hookup, whether you need any ADC, etc
[23:49:23] <cradek> you surely won't need ADC for a knee mill unless you're going to do something unusual with it
[23:49:42] <dmessier> anilam.. should be an easy fit
[23:49:55] <cradek> the mesa and ppmc are plenty capable and affordable
[23:50:19] <cradek> if you might want to do rigid tapping some day, think ahead and make sure you have a spare encoder channel for the spindle
[23:50:30] <skunkworks_> dmessier: do you have experience with anilam?
[23:54:31] <Adam> cradek i was looking at the mesa 5I20 FPGA I/0 would that be suitable?
[23:54:41] <cradek> yes
[23:54:48] <cradek> they have a nice analog servo interface card
[23:55:01] <cradek> +-10 out, differential encoder in
[23:55:05] <cradek> just wire it up
[23:55:23] <Adam> do you have a number for that?
[23:55:24] <cradek> also they have some isolated IO boards for limit/home switches, spindle fwd/rev, etc etc
[23:55:32] <ds2> is it possible to have a second spindle driven by a stepper for rigid tapping?
[23:56:11] <cradek> Adam: analog servo interface is 7I33. Isolated IO is 7I37.
[23:56:17] <cradek> (I'll be using both of those on my bridgeport very soon)
[23:57:04] <cradek> you'll have to decide whether 16 in/8 out is enough - it's not a lot of extra.
[23:57:36] <cradek> ds2: it would take a BIG stepper to tap wouldn't it? why a second spindle?
[23:58:04] <Adam> I have only 2 axis right now, in the future i would like to add the z-axis.
[23:58:37] <cradek> oh it's only XY under cnc control? interesting
[23:58:44] <Adam> Once I have thoose two boards what are we looking at for configuration and wiring? is it a very time consuming process for a rookie?
[23:58:48] <Adam> yeah only xy
[23:59:18] <cradek> I hesitate to guess because I don't know your skills.
