[00:00:44] <jthornton> it's under control now so it is just a matter of time...
[00:02:05] <skunkworks> neat!
[00:03:38] <jthornton> I think I can set this on on your table skunkworks
[00:04:54] <theorb> theorb is now known as theorbtwo
[00:07:11] <jthornton> yea, if the control sucks it won't take me long to EMC it
[00:07:45] <jthornton> step 2 of 27

[00:17:13] <jthornton> the inspector general checks it out

[00:34:13] <skunkworks> 2 axis index homing!
[00:36:18] <cradek> wooo!
[00:36:51] <cradek> how's Z backlash?
[00:48:10] <skunkworks> have not got that far :)
[00:53:54] <Valen> nice mill
[00:56:59] <skunkworks> 2 tenths
[00:58:49] <skunkworks> I think we can live with that :)
[01:00:56] <cpresser> inch or mm?
[01:03:31] <skunkworks> inch
[01:07:39] <cpresser> tenths of an inch? that would be 2.5mm.. thats quite alot!?
[01:09:16] <skunkworks> .005mm
[01:09:27] <skunkworks> .0002"
[01:09:59] <cpresser> ah okay... 2 tenths of 1/1000 inch.. now I get it :)
[01:10:23] <cpresser> sorry for asking,... but in fact, I dont get the imperial sys#tem :)
[01:11:28] <skunkworks> me either ;)
[01:11:38] <cpresser> its quite hard to understand for european people. at least for me :)
[01:39:25] <Jymmm> "Walk a kilometer in his shoes" just doens't have the same inpacy imo
[01:39:30] <Jymmm> impact
[01:40:11] <Jymmm> 25.4mm Worm
[02:44:01] <cradek> skunkworks: that sounds great
[02:44:35] <skunkworks> 1 more axis to go :)
[02:44:42] <cradek> anything hard about y?
[02:44:50] <skunkworks> nope - just needs to be donw
[02:44:52] <skunkworks> done
[02:44:59] <cradek> yay you'll have it tomorrow I bet
[02:45:18] <skunkworks> heh
[02:46:49] <cradek> hope Y is tight as X, so you can put a probe on it and use it as a cmm like I do
[02:46:56] <skunkworks> heh
[02:47:02] <cradek> unless of course you already have a real cmm...
[02:47:14] <skunkworks> I think z is probably the worse
[02:47:54] <skunkworks> we goofed around with y a few months ago and could not feel any backlash
[02:48:30] <skunkworks> z could probably be tightened up some more - but we will probably run it for a bit and see if it stays consistant.
[02:49:29] <skunkworks> I am sore. :)
[02:49:36] <cradek> .0002 doesn't matter - your screw will grow and shrink more than that
[02:50:22] <skunkworks> yes - I am not 100% sure about the scaling - doing a quick check - I seemed to be about .015 off over about 15 inches
[02:50:50] <skunkworks> so - either it isn't 5mm per turn - or the ballscrews are not exactly 3tpi
[02:50:51] <cradek> what do you have for a 15" standard?
[02:51:08] <skunkworks> we have a 3ft caliper
[02:51:18] <cradek> ah
[02:51:31] <skunkworks> wait - it must be 2ft
[02:52:15] <skunkworks> should have measured x.
[02:52:19] <cradek> it's not immediately clear to me how you'd use that...
[02:52:21] <skunkworks> ran out of steam
[02:52:48] <skunkworks> we used it like depth micrometer
[02:53:03] <skunkworks> along the way
[02:53:06] <cradek> oh the sticky out end
[02:53:12] <skunkworks> yes
[02:53:21] <cradek> yeah you could approach that step with a dti (same direction both times)
[02:53:24] <skunkworks> probably not perfect - (not really worried yet) ;)
[02:56:50] <skunkworks> very happy so far. :)
[06:59:14] <alex_joni> http://www.michaelv.org/
[07:10:10] <awallin> that must be this virtualization and cloud-computing that everyone is talking about nowadays
[07:15:56] <alex_joni> awallin: surely :)
[07:24:44] <djwez> hey guys im back again and still having problems
[16:31:32] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website:
http://www.linuxcnc.org/, wiki at
http://wiki.linuxcnc.org/"
[17:03:44] <skunkworks> cradek: that is pretty close to what I got manually (raising the output scale until the amp gain was almost all the way up :))
[17:06:46] <cradek> cool, so it works right when you fix the scale?
[17:06:58] <skunkworks> yes - I get the 200ipm I am shooting for
[17:07:26] <skunkworks> did you see
http://www.youtube.com/watch?v=QU_O_Z7Vv8c
[17:07:57] <cradek> yes very cool :-)
[17:08:11] <skunkworks> dad is busy getting y working
[17:08:47] <Jymmm> skunkworks: acme?
[17:09:23] <skunkworks> hope not ;)
[17:09:23] <cradek> I bet the end is in sight now, you'll both be unstoppable
[17:10:25] <Jymmm> skunkworks: looks like 1" acme in your video to me
[17:11:17] <Jymmm> @25s
[17:13:14] <skunkworks> Jymmm:
http://electronicsam.com/images/KandT/conversion/xaxis/ballscrew.JPG
[17:13:20] <Jymmm> skunkworks: When you get it all completed, you can make me a a 1" PCB with 40 thru hole components
[17:13:54] <Jymmm> skunkworks: My, you have tiny hands =)
[17:14:20] <jthornton> VMC in center of trailer --- check, shower --- check, cold Weihenstephaner Original Premium --- in progress, nap --- up next
[17:14:44] <skunkworks> jthornton: Always good to have a plan ;)
[17:14:47] <Jymmm> jthornton: WHERE'S THE BEEF?
[17:15:06] <jthornton> it's going to be chicken
[17:15:18] <jthornton> I love it when a plan comes together :)
[17:16:11] <Jymmm> jthornton: road trip remix tape?
[17:17:32] <jthornton> Que?
[17:17:57] <Jymmm> jthornton: music
[17:18:42] <jthornton> can't carry a tune in a bucket :/
[17:20:08] <jthornton> wee! no supporting 4x4's
http://i47.photobucket.com/albums/f163/johnplctech/BP380%20VMC/BP380-06.jpg
[17:20:42] <Jymmm> Nice....not!
[17:21:16] <jthornton> http://i47.photobucket.com/albums/f163/johnplctech/BP380%20VMC/BP380-07.jpg
[17:21:50] <Jymmm> is that tire low on air?
[17:22:04] <jthornton> the left rear?
[17:22:25] <jthornton> http://i47.photobucket.com/albums/f163/johnplctech/BP380%20VMC/BP380-08.jpg
[17:22:49] <Jymmm> I"m going to say all four trailer tires
[17:23:14] <jthornton> no, they had 65 psig in them in those photos
[17:23:50] <Jymmm> Ah. Not going to strap it down?
[17:23:57] <jthornton> I drove it home with 20 psig in the left rear but could not tell as all the weight was on the front axle
[17:25:44] <Jymmm> car trailers are cool, you can use them for anything!
[17:34:23] <Jymmm> Has anyone ever worked with homasote or sound board???
http://www.housatonicrr.com/images/ConstJournal01/PlyHomasoteAndRisers.jpg
[17:36:11] <jthornton> that one is twice as strong as a normal run of the mill trailer with 8 ply trailer tires
[17:36:19] <Jymmm> I was planning on using is for sound proofing, but when I saw it at the store, in BIG 18" letters on each sheet it says "Sparks may cause ignition"
[17:36:39] <jthornton> could be exciting
[17:36:40] <Jymmm> jthornton: Yeah, the tires look beefier
[17:37:39] <Jymmm> Not in this case, I need to line a air scrubber cabinet that has a small dust collector in it with the stuff.
[17:39:03] <IchGuckLive> 2-3tons ? CNC waight
[17:40:22] <Jymmm> WB
[17:41:48] <Jymmm> whats the common name for this rubber things you mount equipment on ?
[17:41:59] <jthornton> isolation mounts
[17:42:42] <Jymmm> that's the COMMN name? I thought it was dampener or something like that
[17:42:50] <Jymmm> brb coffee
[17:43:00] <jthornton> a damper goes in your ductwork
[17:53:48] <jthornton> cold beer --- check, nap --- starting
[17:55:39] <frallzor> * frallzor butchered the old gamepad yesterday to make it useful as a proper pendant
[18:00:18] <Jymmm> Can anyone tink of materials that are heavy and soft (like lead or neoprene)?
[18:02:25] <frallzor> clay
[18:03:39] <Jymmm> frallzor: Well, it dries hard.
[18:03:49] <frallzor> depends on which type
[18:03:53] <frallzor> some keeps soft
[18:03:59] <Jymmm> and need waterless material
[18:04:49] <frallzor> what for?
[18:04:57] <Jymmm> sound supression
[18:05:44] <Jymmm> heavy and soft, as well as porus is the best
[18:05:52] <Jymmm> (sp)
[18:06:44] <archivist> pitch
[18:06:55] <Jymmm> Dust collector
[18:07:05] <archivist> stop moaning
[18:07:17] <Jymmm> primarily the exhaust
[18:07:49] <Jymmm> I'm mounting the DC inside the air scrubber
[18:14:42] <skunkworks> cradek: thanks for the formula - I don't know when I thought it was 9v/3.333 ;) I must have slipped a cog
[18:19:31] <skunkworks> cradek: and I love the homing dance
[18:20:05] <skunkworks> I have not done the thump fix. ( I am homing pretty slow and I can just barely hear the thump)
[18:20:22] <skunkworks> When it finds the index and resets.
[19:04:28] <Fox_Muldr> Fox_Muldr is now known as Fox_M|afk
[19:28:07] <awallin> skunkworks: that's your kearney&trekker doing the 22" circle on youtube?
[19:29:39] <frallzor> oh anyone around that want to help me make some exercisecode for my machine?
[19:29:45] <skunkworks> awallin: yes
[19:31:20] <awallin> looks like a big machine! more than 22" travel on X?
[19:32:08] <skunkworks> 38"
[19:32:08] <awallin> pallet-changer on the table?
[19:32:12] <skunkworks> yes
[19:33:06] <skunkworks> there is no pallet on the machine at the moment. both pallets are on the pallet changers
[19:34:06] <skunkworks> x is 38" y is 36" and z is 24"
[19:34:21] <awallin> horizontal spindle?
[19:34:24] <skunkworks> yes
[19:35:31] <awallin> for big parts then... :)
[19:35:45] <skunkworks> http://electronicsam.com/images/KandT/oldkandt.JPG
[19:35:57] <skunkworks> that is a 60's picture :)
[19:36:11] <awallin> remember the lab-coat as you stand before emc2
[19:36:16] <skunkworks> heh
[19:37:05] <awallin> how many rpm and HP on the spindle?
[19:37:08] <Fox_M|afk> Fox_M|afk is now known as Fox_Mulder
[19:37:37] <skunkworks> we are going to limit it to 3000rpm. If we need higher - we mount a high speed spindle
[19:37:49] <skunkworks> the thing has a 16 speed gear box
[19:40:37] <awallin> maybe the 60's vector VFD wasn't all that good at providing torque at low rpm
[19:41:20] <skunkworks> originally - it had a hydraulic motor for the spindle. (we replaced it with a 5hp 3phase with a vfd)
[19:43:32] <Fox_Mulder> Fox_Mulder is now known as Fox_Muldr
[19:50:27] <skunkworks> wow

[21:53:22] <Jymmm> It's a slide presentation in SVG, only 5KB
[21:54:09] <Jymmm> you can use arrow or scrollwheel to go back
[21:54:59] <Jymmm> cradek: it's all a single file
[21:56:28] <cradek> Jymmm: I guess it would be cool if people can make slideshows with free software, even though slideshows aren't my thing
[21:56:50] <Jymmm> cradek: It was made with inkscape and a extension
[21:57:05] <Jymmm> cradek:
