[10:35:44] <DJ9DJ> re
[11:38:56] <IchGuckLive> hi all B)
[11:39:17] <IchGuckLive> Chemeleon: still on plan
[11:39:24] <Chemeleon> hmm?
[11:39:40] <IchGuckLive> with your massive construction
[11:40:04] <Chemeleon> ah, yea, did a little more adjusting to it yesterday, few suggestions here like bolting through rather than using plates cleaned things up a bit and reduced costs
[11:40:32] <Chemeleon> got the screw drives pretty much worked out, just have to decide for sure on the linear bearing setup to use and it should be good to go I think :)
[11:40:49] <IchGuckLive> agree system 8025 got nice bolt fixing to the ALU
[11:41:35] <Chemeleon> probably wont work on it any more until this evening, have to do some of the business side of things today and then go run a few more carvings off on my current machine before I'll have time for the design work again
[11:41:54] <IchGuckLive> you sghoudt consider a 20/25 Timebelt to come over the 4/5 problem
[11:42:05] <Chemeleon> the 4/5 problem?
[11:42:06] <IchGuckLive> 400steps verses 5mm
[11:42:28] <IchGuckLive> with a 20/25 you are at pricice move by one step
[11:42:43] <IchGuckLive> this gives the interpreter a speedup at 10x
[11:42:56] <Chemeleon> hmm, interesting
[11:42:59] <Chemeleon> I'll have to dig into that :)
[11:43:28] <IchGuckLive> with a 5i25 you migt come to 10m/min this gives you 390ipm
[11:43:37] <Chemeleon> nice :)
[11:44:00] <IchGuckLive> your stepper has 400 steps at full speed and full tourch
[13:09:47] <IchGuckLive> Chemeleon: http://foengarage.de/gears2.html animated gear
[13:09:55] <IchGuckLive> ,ouseover stops
[13:13:28] <IchGuckLive> so if the stepper goes full 400 the 2005 goes only 4mm -> 500steps equals 5mm pitch on 20/25 timebelt
[13:14:09] <jdh> why does one care?
[13:14:43] <IchGuckLive> to get a nice precision
[13:14:44] <mrsun> yeey my router is moving in X and Y now =)
[13:14:56] <CaptHindsight> well, it's better than my 4/5 gear design :)
[13:15:03] <IchGuckLive> mrsun: still 1 axis to go
[13:15:31] <jdh> why not 400:1mm then
[13:15:35] <mrsun> need to make the ballscrew/motormount for it and its hopefully after that just to bolt in place and make a router mount =)
[13:15:48] <mrsun> damn ballscrews makes motors strong btw :P
[13:15:50] <IchGuckLive> jdh: the 2005 got 5mm/Ref
[13:15:59] <mrsun> or the motors are that strong i guess but ballscrews make them show it :P
[13:16:10] <jdh> yeah, but you can get whatever you want
[13:16:39] <IchGuckLive> idf the stepper got 400 steps does not meet a good 0.01
[13:16:47] <IchGuckLive> on 5mm tread
[13:16:57] <IchGuckLive> 0,125
[13:17:01] <IchGuckLive> 0,0125
[13:17:54] <IchGuckLive> smouth motion and full speed at pricice stepping
[13:18:22] <IchGuckLive> mrsun: 2005 ?
[13:18:32] <mrsun> IchGuckLive, huh ?
[13:18:32] <IchGuckLive> or 2505
[13:18:40] <IchGuckLive> the ballscrew
[13:19:02] <mrsun> 2005
[13:19:06] <mrsun> for X and Y
[13:19:14] <mrsun> 1605 for Z
[13:19:20] <IchGuckLive> at 1000mm
[13:19:31] <mrsun> huh ? :)
[13:19:39] <IchGuckLive> length
[13:19:43] <mrsun> 1.4 meters
[13:19:56] <IchGuckLive> total or motion
[13:19:59] <mrsun> huh ?
[13:20:03] <mrsun> wghy are you asking me this? :P
[13:20:24] <IchGuckLive> going to make a fast plasma
[13:20:47] <IchGuckLive> im only using TR 20x4
[13:20:53] <mrsun> 1.2 meter total movement -X and Y
[13:20:55] <mrsun> some more maybe
[13:21:01] <mrsun> but thwas what it is designed for
[13:21:13] <IchGuckLive> ok
[13:21:23] <mrsun> so i can take half sheets of wood and just smack em into the machine =)
[13:21:42] <IchGuckLive> agree
[13:21:43] <archivist> he never reads the line where you said router
[13:21:51] <IchGuckLive> therfor plasma is also 2.5m
[13:21:58] <IchGuckLive> takes the hole sheet
[13:22:35] <IchGuckLive> 2nd and 3rd mashine is on rack,pinion
[13:22:41] <IchGuckLive> 30:1
[13:23:13] <IchGuckLive> T10 metric
[13:23:39] <IchGuckLive> Z12 makes a U120mm
[13:24:00] <archivist> monologue
[13:24:09] <IchGuckLive> 400Steps x 30:1 gives a 12000Steps per Z12 ref
[13:24:17] <IchGuckLive> so 0,01mm precice
[13:24:55] <mrsun> my guess is that you do not need that for a plasma :P
[13:25:06] <IchGuckLive> agree
[13:25:14] <IchGuckLive> also not for the woodcutter
[13:25:17] <CaptHindsight> uPlasma
[13:25:20] <IchGuckLive> so gear 30:1
[13:25:26] <IchGuckLive> change to 3:1
[13:25:31] <IchGuckLive> timebelt
[13:25:48] <mrsun> btw got an error in axis .. that hmm "axis 0 could not track" or something like that, what is that?
[13:25:53] <mrsun> to fast pulsing out or something ?
[13:25:56] <mrsun> ive got no encoders etc
[13:26:12] <IchGuckLive> 120mm/U meets 400x3 steps
[13:26:29] <IchGuckLive> precise 0,1
[13:28:55] <IchGuckLive> ok im off by
[13:28:58] <IchGuckLive> B)
[13:37:40] <Loetmichel> hmm, i really want to know if IchGuckLive ist from former GDR. because his enlish reads like he was learning it by speaking/hearing, not from books ;-)
[15:33:17] <andypugh> pcw_home: Ye there?
[16:04:08] <joebog> andypugh I have made a new controller based on the Mesa boards, Ill be connecting it today.
[16:04:25] <joebog> is there some test software that I can use to test it ?
[16:04:53] <andypugh> Depends what you want to test..
[16:05:19] <joebog> the three motors that I have
[16:05:22] <andypugh> What hardware is it?
[16:05:27] <joebog> setup in the engraving machine
[16:05:51] <andypugh> pncconf has an axis test, I think.
[16:06:06] <JT-Shop> does that work?
[16:06:07] <andypugh> And will help with the Mesa configuration.
[16:06:10] <joebog> it used to have a Cipher windowz controller fitted to it
[16:06:14] <andypugh> JT-Shop: Good question
[16:06:25] <andypugh> Which Mesa hardware?
[16:06:35] <JT-Shop> I seem to remember something about it not working but not much else
[16:06:38] <joebog> 6560 boards
[16:07:06] <joebog> me made power supply and mesa breakout board
[16:07:09] <JT-Shop> a basic config for the Mesa board might be the easy way
[16:07:22] <andypugh> Which Mesa breakout?
[16:07:46] <joebog> hhmm cant remember the number :D
[16:08:07] <joebog> 5 chan breakout it was a kit I bought
[16:08:14] <andypugh> 5i20, 5i22, 5i23, 5i25?
[16:08:31] <andypugh> Sounds likely to be the 5i25 / 7i76 combination?
[16:08:55] <andypugh> (Calling it a "breakout" is something of a misnomer)
[16:09:39] <andypugh> It's a bit like describing your PC as a USB hub. It sort-of is, but...
[16:10:01] <joebog> hhmm the very lousy manual says its a 4/5 axis CNC controller
[16:10:49] <joebog> 5i25/7i76 sounds close
[16:10:49] <andypugh> That doesn't sound like a Mesa card...
[16:11:00] <andypugh> Ah, well that is then.
[16:11:29] <andypugh> First test I would do from the command line:
[16:11:51] <joebog> Univelope ??? I bought it from cncgeeker.com
[16:11:52] <andypugh> halrun // loadrt hostmot2 // loadrt hm2_pci // show pin // exit
[16:12:43] <andypugh> I am confused now.
[16:12:52] <andypugh> Is this a Mesa setup or not?
[16:13:12] <joebog> I believe so
[16:13:49] <andypugh> I don't think cncgeeker sell Mesa.
[16:14:06] <JT-Shop> nope, no Mesa there
[16:14:20] <JT-Shop> Chinlee boards only
[16:14:58] <andypugh> This? http://www.cncgeeker.com/index.php?main_page=product_info&cPath=1&products_id=43
[16:15:13] <andypugh> That's a normal parallel port preakout + drivers.
[16:15:19] <joebog> http://www.cncgeeker.com/index.php?main_page=product_info&cPath=1&products_id=2
[16:15:47] <joebog> that was the kit I bought
[16:16:08] <andypugh> Yeah, same thing. Standard paralel-port breakout kit and a set of stepper drivers.
[16:16:45] <andypugh> (And didn't we already conclude that the drivers are a lot smaller than the original Cipher ones?)
[16:17:00] <joebog> 1 amp smaller
[16:17:14] <andypugh> Or, 30% whichever sounds better.
[16:17:21] <joebog> BUT I want to see where linuxcnc software working first
[16:17:38] <joebog> then Ill build a final unit thats correctly reated
[16:17:51] <joebog> rated
[16:17:56] <andypugh> Right, hook it all up then fire up the Stepconf wizard.
[16:18:08] <joebog> I wont be loading the motors, or driving at high speed
[16:19:50] <andypugh> No clues in the manual of the step-timing requirements. Try 5000 everywhere.
[16:20:11] <joebog> the manual sucks !!!
[16:20:22] <joebog> 4 pages photocopied
[16:21:46] <joebog> a description of the pins i.e. pin 3 = <1 volt low > 2.5 volts high
[16:22:07] <joebog> max speed 25khz
[16:23:20] <joebog> I bought a demo version of the cipher software !! 5 fonts total but it will scale to any( almost) size
[16:23:32] <joebog> cost = $7500 !!!!!!!
[16:24:03] <joebog> thats why I spent 120 bucks on the boards to test the setup after rewiring the engraver machine
[16:25:38] <DJ9DJ> gn8
[16:27:57] <andypugh> $7500 for the demo?
[16:28:12] <joebog> nope
[16:28:18] <joebog> the demo was $40
[16:28:19] <JT-Shop> I'd try the TB6560 settings http://www.linuxcnc.org/index.php/english/forum/49-basic-configuration/26211-sample-configurations
[16:28:37] <joebog> but what it explains is that its purly an engraving machine setup
[16:28:39] <andypugh> Ah, OK. The demo might be enough to scope out what happens on the sriver boards too.
[16:29:10] <joebog> Im not going to use the cipher stuff
[16:29:18] <joebog> NOBODY hates windowz like me
[16:29:31] <joebog> I dont have it, wont buy it, wont steal it
[16:30:09] <joebog> runs under xp service pack 2
[16:31:25] <joebog> I have been a unix man for about 35 years
[16:32:02] <joebog> BUT Im hardware eng
[16:32:11] <joebog> dont know nuffin about software
[16:36:32] <andypugh> Software fails more cheaply.
[16:36:55] <andypugh> If this code was components I would be having to dig down to get out the door.
[16:36:57] <joebog> 7500 failure is cheap ???
[16:37:36] <joebog> and at the end of the day it does nothing except engrave letters and numbers
[16:38:00] <joebog> the gunsmith wants to engrave oak leaves and stuff onto hand made shotguns
[16:38:03] <joebog> etc etc
[16:38:50] <joebog> scrollwork and to cut dovetails into the barrels then fill them with gold
[16:39:53] <andypugh> Classy
[16:40:11] <joebog> he is a master craftsman
[16:40:30] <joebog> it sounds a lil fantastic I know, but he does beautiful stuff
[16:40:39] <joebog> even if it is guns !!
[16:41:01] <joebog> he makes superb Pope barrels !!
[16:41:31] <joebog> They are for rifles of course
[16:41:31] <andypugh> You keep popes in barrels?
[16:41:42] <joebog> :D
[16:42:03] <joebog> heh heh heh I didnt know what they were either !!!
[16:42:21] <joebog> but they are rifle barrels that have variable twist in the rifling
[16:42:48] <joebog> most guns have rifling like a screw thread, that is same pitch all the way down the barrel
[16:43:24] <joebog> a Pope barrel starts of straight and slowely accelerates the twist so that the spin on the projectile is controlled
[16:44:08] <joebog> the accuracy is the best there is and is repeatable
[16:45:31] <joebog> http://riflemansjournal.blogspot.com.au/2010/08/history-pope-rifle-barrels.html
[16:46:04] <joebog> it may not be your bag ( it isnt mine either) but the engineering is excellent !!!
[16:47:49] <andypugh> I used to really like shooting actually, but I found I didn't like shooters.
[16:48:15] <andypugh> I shot for my college at university.
[16:48:37] <joebog> for instance a .22 calibre rifle shooting 200 yards after firing 50 rounds there was only ONE hole in the target !!!! now thats impressive !!!
[16:48:51] <andypugh> But I seemed to be the only one who wanted to shoot rifles at paper targets, the rest of the club seemed to want to be Dirty Harry.
[16:49:03] <joebog> yup
[16:49:08] <joebog> mostly the same here
[16:49:53] <joebog> the latest gun he has made for some wan*er is .457 calibre with a .577 cartrdge necked down to winchester .457 !!!
[16:50:09] <joebog> about the same gun as is fitted to a Abrams tank !!!
[16:50:34] <joebog> yet the largest animal we have here is a roo
[16:51:06] <andypugh> Aren't the 'Roos wearing kevlar nowadays?
[16:51:28] <joebog> heh heh heh not that I have noticed :D
[16:51:47] <joebog> between town and here ( home) there will be at least ten roadkill
[16:51:53] <andypugh> My dad nearly caught a wallaby in their garden a couple of weeks ago. Somewhat unexpected in Yorkshire
[16:52:41] <joebog> my backyard is full of em in winter
[16:52:56] <joebog> they come for the grass cause the rest of the country is dry as

[16:54:00] <andypugh> JT-Shop: Something makes me think I don't want to watch that.
[16:54:32] <JT-Shop> it's ok, the deer bounced off the bke and he didn't fall down
[16:54:40] <JT-Shop> lucky guy
[16:55:23] <joebog> probably a Hardly Ferguson bike :D
[16:55:38] <joebog> AKA tractor or air compressor on wheels
[16:55:44] <JT-Shop> Suzuki
[16:56:26] <joebog> nifty bit of news andy :)
[16:56:34] <joebog> the roo I mean
[16:56:55] <andypugh> Which reminds me, at work on wednesday I saw a Norton 961, a De Lorean and a Ferrari Dino with 30 feet of each other .
[16:57:11] <joebog> anyway Ill be posting some more pics on the engraveing machine and my quick mockup of power supply and driver boards
[16:57:29] <andypugh> It was our annual "bring your motorised toy to work" day.
[16:58:07] <andypugh> There were lots of other Ferarris and Astons, Jags, several Loti. But those three stood out for me.
[16:59:00] <joebog> they only made a few de loreans didnt they ?
[16:59:10] <joebog> idiot got busted for drugs wasnt he ?
[16:59:33] <joebog> irish car
[16:59:40] <joebog> what else :D
[17:00:25] <andypugh> Yeah, I think he was trying to improve cashflow by unconventional means.
[17:52:14] <jp__> got the panel ready to test.
[17:52:18] <jp__> http://imagebin.org/270739
[17:56:09] <joebog> I will have mine done today too
[19:08:54] <JT-Shop> well I spend too much time on this stupid computer and didn't make any chips this evening
[19:22:32] <JT-Shop> say goodnight Gracie
[19:37:46] <andypugh> I haven't created any swarf for weeks.
[19:38:17] <jp__> is there a way to make a lice cd from an image of my pc?
[19:38:28] <jp__> live cd
[19:38:34] <AR__> i havent made any chips since i finished my gun
[19:38:36] <AR__> heheheh
[19:40:24] <Tom_itx> went to fix my bud's Tree cnc yesterday
[19:43:38] <andypugh> Where did Tree make stuff?
[19:44:18] <Tom_itx> they're some fairly hefty mills
[19:44:30] <Tom_itx> this one's seen better days
[19:44:40] <Tom_itx> yasnak control no longer made
[19:45:20] <Tom_itx> this is the one he replaced the spindle and ballscrew bearing in
[19:46:18] <Tom_itx> he had a deadline on some parts so i went out to help get him goin again
[19:46:19] <andypugh> The same "Tree" as http://www.lathes.co.uk/bridgeport/page13.html ?
[19:56:35] <Tom_itx> andypugh, no
[19:57:26] <andypugh> There was a Tree who made a really neat taper-cutting boring head.
[19:58:24] <Tom_itx> http://lovelandscrewmachine.com/Images/Tree_2.JPG
[19:58:27] <Tom_itx> somewhat like that
[19:58:36] <Tom_itx> fully enclosed VMC
[19:58:54] <Tom_itx> 16 tool changer iirc or maybe 20
[20:01:42] <Tom_itx> http://www.fpmiller.com/Inventory/Pages/3133.aspx
[20:01:48] <Tom_itx> that one has a different control
[20:02:11] <Tom_itx> but looks alot like his
[20:07:28] <andypugh> Anyhow, time to give up for the night.
[20:07:41] <Tom_itx> me too, i'm bushed
[20:11:45] <Valen> ey Tom_itx, you in #hackvana?
[20:13:32] <jp__> valen: hows things?
[20:14:07] <Valen> busy busy bot not in the making lots of money way lol
[20:14:37] <jp__> yeah funny how that works
[20:14:51] <jp__> well not really
[20:16:22] <jp__> thanks for buying those boards after 3 years i have finally cleaned up the mill and put everything in its place
[20:17:11] <Valen> lol, its always the way
[20:17:45] <jp__> yeah. funny how work gets done when your hand gets forced
[20:27:29] <joebog> well the magic smoke didnt get out :)
[20:27:52] <joebog> but I cant make any axis move
[20:28:31] <Valen> jp__: we got the parts we needed to make out, now I just need to get some servo motors and I'm set ;->
[20:29:03] <joebog> Im only looking for the on/off switch :)
[20:29:41] <joebog> I have the controllers and motors all connected up intoa big engraving machine
[20:29:46] <joebog> but nothing moves
[20:32:18] <Valen> time to start the diagnosing i guess
[20:32:27] <Valen> firstly is it turned on?
[20:32:34] <Valen> F1 and F2 usually
[20:35:26] <jp__> Valen: where r u getting the motors from?
[20:35:48] <Valen> dunno yet
[20:35:53] <Valen> probably keling
[20:35:55] <Valen> or whatever
[20:35:58] <Valen> automation direct

[21:06:47] <jp_mill> hmm went to upgrade lcnc from 2.4 to 2.5 on hardy and package manager cant find python rep to tcl rep
[21:26:23] <joebog> anybody help me with initial config file ?
[21:26:54] <joebog> stepmill config
[21:30:12] <joebog> you actually herte JP
[21:30:17] <joebog> here
[21:33:40] <rick_> hi to all
[21:33:55] <rick_> theres anybody here_

[21:35:44] <joebog> I could use some help though :)
[21:36:08] <joebog> welcome then
[21:36:28] <rick_> thanks
[21:36:30] <joebog> normally ( like 5 or 6 hours ago) there are many here that are not sleeping
[21:38:11] <Tom_itx> Valen, no i'm not there
[21:38:17] <rick_> good to know that, is late here too, shortly i will go to sleep, i want to log in to see whats like this irc
[21:38:23] <rick_> je je
[21:39:54] <rick_> long time emc2/lcnc user, great comunity
[21:42:29] <rick_> some one notice a master branch 2.6.pre 0 with a mod to use as a foamcutter or a wire edm?
