[00:00:09] <Valen> itty bitty microswitch its all good ;->
[00:00:09] <tjb1> dragging the switch arm all over the stock :p
[00:00:19] <tjb1> Getting it stuck in a hole…bye bye switch
[00:00:22] <tjb1> lol
[00:01:32] <tjb1> I need to add a bolt in front of the prox sensor so I can make the probe distance smaller
[00:02:00] <Valen> put the switch behind the torch and let it pivot up when you hit the job
[00:02:06] <Valen> use a contact probe
[00:02:17] <Valen> anything like that, then you don't need that second slide
[00:02:19] <tjb1> im not redesigning again
[00:02:27] <Valen> but but your using linux
[00:02:36] <Valen> your sposed to redesign it endlessly
[00:02:48] <tjb1> thats the 3rd design of the z axis
[00:03:38] <tjb1> i need a prox sensor with larger sense distance
[00:03:48] <tjb1> anything over 35ipm and this one gets hit
[00:04:01] <Valen> during probing?
[00:04:05] <tjb1> yes
[00:04:18] <Valen> make it a sliding contact not end on perhaps?
[00:04:26] <tjb1> so add another slide :P
[00:04:36] <Valen> not quite
[00:04:39] <tjb1> ill deal with it
[00:04:49] <Valen> just rotate the switch 90 degrees so the plate moves past it
[00:04:50] <tjb1> Ill just cut probe height down to like .1 or something
[00:05:53] <tjb1> alright bed time…gonna make the y wire chain mounts tomorrow
[00:05:57] <Valen> have fun
[00:06:06] <tjb1> Im dreading this chain
[00:06:15] <tjb1> but oh well
[00:06:22] <Valen> chain drive huh?
[00:06:50] <tjb1> no
[00:06:54] <tjb1> The chain to hold the wires
[00:07:02] <Valen> ahh cable tray thingie
[00:07:13] <Valen> r00t4rd3d: you can see our camera here http://www.cnczone.com/forums/showthread.php?p=927505#post1004601
[00:07:18] <Valen> well the edge of it lol
[00:07:22] <tjb1> not a very friendly mounting situation on the y axis
[00:07:29] <Valen> could use our solution
[00:07:38] <Valen> bungy cord holding wires from the roof
[00:08:05] <tjb1> thats my torch solution :P
[00:08:37] <Valen> works for me ;->
[02:01:52] <Loetmichel> mornin'

[03:39:49] <Pilla_CNCpc> Hello!~
[04:55:24] <pilla_> hi all \o/
[04:55:39] <pilla_> I feel such a noob, but I can't get pcb2gcode to work >.>
[04:56:06] <pilla_> I installed it and such, on lucid, did ./configure, make, sudo make install
[04:56:22] <pilla_> and when I want to read the help by typing pcb2gcode --help
[04:56:41] <pilla_> I get "pcb2gcode: command not found"
[04:56:51] <pilla_> I'm probably missing something very stupid xD
[04:57:49] <pilla_> Does anyone have any recommendations to turn .drl, .drr and a .txt file into a .ngc file?
[04:59:48] <pilla_> or at least something linuxCNC can open
[05:05:37] <dimas> pilla_, do you have pcb2gcode execution file in the same directory you run above commands in?
[05:06:55] <dimas> pilla_, also look for installation directory in MAKEFILE - what is it?
[05:08:13] <dimas> on my machine i would run "sudo updatedb" and then "locate pcb2gcode" to find where it was installed
[05:26:57] <pilla_> Dimas: Yes I have it in the same directory
[05:27:49] <dimas> try to run it as "./pcb2gcode"
[05:28:15] <dimas> "./pcb2gcode --help"
[05:28:26] <dimas> without quotes
[05:29:00] <pilla_> That doesn't work either
[05:29:08] <pilla_> "no such file or directory"
[05:29:13] <pilla_> oh wait
[05:29:32] <pilla_> nope
[05:29:50] <pilla_> I don't have anything that looks like an executable in that folder either
[05:32:09] <Valen> did you make it an executable?
[05:32:27] <pilla_> dunno, what's the filename I'm looking for?
[05:32:31] <Valen> actually does pcb2gcode do an install?
[05:32:46] <Valen> I'd suggest doing a find / -iname "pcb2gcode"
[05:33:12] <Valen> perhaps throw a sudo in front of it to shut it up about the inaccessable directories
[05:33:17] <pilla_> xD
[05:33:55] <pilla_> only thing it finds is /home/pilla/pcb2gcode
[05:34:45] <pilla_> hmz
[05:38:07] <dimas> pilla_, wonder what make install actually did
[05:39:03] <dimas> you can rerun it and look closely
[05:40:18] <pilla_> pastebin.com/wet2NKLU
[05:40:23] <pilla_> I don't see anything really
[05:41:05] * pilla_ le confused
[05:43:16] <pilla_> mmm
[05:43:52] <pilla_> if I don't do it as root, I get an error "cannot remove usr/local/share/man/man1/pcb2gcode.1; permission denied"
[05:45:18] <pilla_> weird
[05:45:24] <pilla_> I don't see a file like that there at all
[05:45:43] <pilla_> oh now I do :p
[05:48:45] <pilla_> I have no idea what I'm doing x__o
[05:50:08] <pilla_> isn't there some kind of add-on or something to LinuxCNC making it able to open .drr and .drl files?
[05:50:57] <dimas> pilla_, where have you got pcb2gcode from? can i download and test?
[05:51:14] <pilla_> ehm
[05:52:51] <pilla_> sourceforge.net/projects/pcb2gcode/files/
[05:52:56] <pilla_> and there the latest version
[06:03:49] <pilla_> does it work?
[06:04:16] <dimas> pilla_, hold on, i'm trying
[06:05:09] <pilla_> I'll be back in a few minutes, need to move
[06:05:14] <pilla_> class over
[10:17:43] * JT-Shop is making a tap drill selector that displays all the drills between 50% and 90% for the tap selected
[10:17:55] <JT-Shop> in python gtk glade
[10:20:34] <JT-Shop> and sqlite to store the tap and drill data in
[10:21:12] <pilla_> -.- that took waaaaaaaaaaaaay longer than expected
[10:22:21] <pilla_> I forgot who was helping me some hours ago ;..;
[10:22:45] <pilla_> I had to leave since another class wa about to begin, and my laptop doesnt work on the wireless network
[10:23:15] <pilla_> and then my bf picked me up and we went shopping. Long story short, I poofed for much longer than I intended to XD
[10:37:56] <skunkworks> We don't get many of you on this channel....
[10:38:07] <JT-Shop> LOL
[10:38:42] <JT-Shop> http://blindhogg.com/eerfgrinder.html
[10:43:40] <awallin> why such a long belt, if the grinding is against the big wheel anyway?
[10:44:16] <JT-Shop> some have flat surfaces and reconfigure the grinder to the job
[10:44:31] <JT-Shop> otherwise I dunno...
[10:44:55] <skunkworks> pilla_, are you using pcb-gcode in eagle?
[10:45:16] <skunkworks> pcb2gcode
[10:50:59] <skunkworks> never mind.. (googled pcb2gcode)
[10:57:48] <Jymmm> Other than "shim stock", where would (or what industries) would you find 0.010" (0.254mm) stainless steel used in?
[10:58:54] <Jymmm> The only other item I can think of is smd stencils
[11:05:53] <pcw_home> and thats pretty thick for SMD stencils
[11:06:57] <Jymmm> is it?
[11:07:04] <pcw_home> yes
[11:07:40] <pcw_home> typical stencils are 5-6 mills
[11:08:02] <Jymmm> ah
[11:08:22] <pcw_home> Im sure its available for cases where you want a lot of solder
[11:08:33] <Jymmm> sure
[11:09:21] <pcw_home> must be a material you can just buy in bulk somewhwre
[11:10:44] <JT-Shop> how hard and wide?
[11:11:20] <JT-Shop> http://www.mcmaster.com/#shim-stock/=jou5n8
[11:23:22] <Jymmm> I've found the material, I'm looking for the industries that use it (other than shim stock)
[11:26:54] <JT-Shop-2> gotcha
[11:55:21] <tjb1> JT-Shop: You awake?
[12:20:33] <jthornton> it's mighty close to nap time
[12:24:03] <tjb1> That touchoff, is it missing a G91 move?
[12:24:27] <jthornton> which touchoff?
[12:24:29] <tjb1> The z.070 on the one you have uploaded
[12:24:33] <tjb1> torch touchoff
[12:24:50] <tjb1> Nevermind…the g91 is right above it.
[12:24:54] <jthornton> if it is the one I use it is complete
[12:25:03] <tjb1> It was late last night when I was doing that
[12:25:14] <jthornton> understand
[12:25:36] <tjb1> I did get the touchoff and wait for arc to work
[12:26:07] <tjb1> I cant get a proper pierce and cutting height though because of the shield I have
[12:26:43] <tjb1> I could propably put the gouging shield on the torch
[12:26:43] <jthornton> why
[12:27:05] <tjb1> The shield on it is preset for dragging torch so its already set at like .1"
[12:27:30] <jthornton> oh you have the drag shield
[12:27:41] <tjb1> Its what came on the hand torch
[12:27:45] <jthornton> you need the machine torch shield that lets the tip stick out
[12:28:03] <jthornton> you using the hand torch?
[12:28:09] <tjb1> yes
[12:28:29] <jthornton> machine shield should fit
[12:29:28] <tjb1> Shield I have is 220675, thats the gouge shield but the nozzle its about flush with the end of it
[12:30:28] <jthornton> that would work, I don't know the number of the one I use it is out in the shop
[12:30:40] <tjb1> http://www.kaboodle.com/hi/img/b/0/0/13b/3/AAAACx8l9EAAAAAAATs1Wg.jpg?v=1300478484000
[12:30:52] <tjb1> Machine shield is 220673
[12:32:30] <tjb1> I have 4 electronics/nozzles left :)
[12:32:35] <tjb1> electrodes...
[12:33:13] <tjb1> Here is where I got last night - http://www.facebook.com/v/4435982933679
[12:33:46] <jthornton> normal shield 120979 is the one I use
[12:34:27] <tjb1> What cutter you using?
[12:34:49] <jthornton> ouch, I would not use a prox like that
[12:34:54] <jthornton> T80M
[12:35:28] <tjb1> why not?
[12:35:43] <jthornton> if anything goes wrong the prox is destroyed
[12:36:05] <jthornton> we never use a prox like that
[12:36:41] <tjb1> The prox was $2 :P
[12:36:56] <IchGuckLive> Hi All
[12:37:20] <jthornton> still a bad engineering practice even if someone gave you the prox
[12:38:51] <tjb1> I dont think that stepper could hurt it
[12:39:26] <TekniQue> what are we talking about?
[12:39:31] <TekniQue> what's wrong there?
[12:40:38] <tjb1> If a problem arrises I will move it
[12:41:01] <FinboySlick> tjb1: Your big green machine is coming along nicely.
[12:42:15] <tjb1> Thanks FinboySlick
[12:42:34] <tjb1> jthornton: What if I locktite the top nut, loosen the bottom one about .5" and put a spring in there?
[12:42:38] <tjb1> ;)
[12:42:40] <TekniQue> tjb1: are they talking about the proximity sensor used to detect torch height?
[12:42:47] <tjb1> Yes TekniQue
[12:42:58] <TekniQue> I don't see what's wrong with that approach
[12:43:12] <TekniQue> I mean, that's what these sensors are for
[12:43:13] <tjb1> If Z doesnt stop it runs into the prox sensor
[12:43:15] <jthornton> I'm not saying you need to move that one, just pointing out it is a bad method to use a prox unless you have a physical stop for the target
[12:43:17] <TekniQue> sure
[12:43:29] <TekniQue> my machine would run into the homing sensors if it didn't stop
[12:43:57] <jthornton> common practice is to pass the target across the face of the prox
[12:44:04] <tjb1> I might just put a spring on there anyway…anything over 35ipm and its hitting the prox
[12:44:23] <TekniQue> jthornton: but is that as precise as running up to the face of the sensor?
[12:44:31] <jthornton> yep
[12:45:45] <tjb1> jthornton: on yours, is the .070 the distance between the bottom of floating and tripping the switch?
[12:46:31] <jthornton> the distance the Z moves from the time the tip contacts the work and the switch trips
[12:46:55] <jthornton> I think you said the same thing
[12:47:29] <tjb1> ALright good, thanks
[12:48:26] <tjb1> Im going to add a shcs to mine right where the prox senses the floating plate to adjust it down, its currently at .608 and takes a while :)
[12:49:08] <jthornton> :)
[12:50:15] <tjb1> Working on gantry wire chain now
[13:01:04] <IchGuckLive> open office base is so fustrating
[14:08:50] <mrsun_> 60 vs 45 degree dovetails ?
[14:09:00] <mrsun_> advantages?
[14:09:43] <archivist> depends where the dovetails are used :)
[14:10:16] <archivist> my first dovetails were in a cabinet at school
[14:10:51] <mrsun_> in machines =)
[14:10:55] <mrsun_> found a forum thread about it
[14:11:02] <mrsun_> aparently depending on how the forces act
[14:11:39] <archivist> my sliding head has an unusual dovetail with a taper gib in the same direction as the dovetail
[14:12:37] <archivist> has edge screws to adjust rather than end like many taper gibs
[14:20:50] <mrsun_> aparently neither 45 nor 60 degree is good :P
[14:21:42] <archivist> url?
[14:22:13] <mrsun_> http://www.practicalmachinist.com/vb/general/dovetail-angles-140531/#post687024
[14:22:21] <mrsun_> thats one person tho
[14:25:39] <archivist> some prefer rectangular, but there are reasons to prefer one design over another depending on machine use and forces
[14:30:03] <mrsun_> rectangular as in box section or whatever its called? :)
[14:32:56] <archivist> my drill column I am about to use for the 5 axis was rectangular
[14:34:54] <archivist> there was a site showing the various types
[14:35:44] <ReadError> *sigh*
[14:35:49] <ReadError> been lookin at some bigger mills
[14:35:56] <ReadError> and the spindle speeds seem so slow
[14:36:08] <ReadError> im pretty sure i need a higher speed for some of the stuff im doing
[14:36:09] <FinboySlick> ReadError: You want mine? It's got 24krpm.
[14:36:20] <ReadError> whatcha got
[14:36:39] <FinboySlick> Hehehe, a piece of crap.
[14:36:48] <FinboySlick> But I'll send if your way for 10k.
[14:38:32] <archivist> hmm useful service near me http://www.slidewayservices.co.uk/capacity.html
[14:39:19] <FinboySlick> archivist: Oooh, I could send my table there.
[14:39:59] <archivist> there should be a service like that near you
[14:40:08] <FinboySlick> archivist: Nothing is near me.
[14:40:14] <FinboySlick> I'm in eastern Quebec.
[14:41:24] <archivist> http://www.manta.com/ic/mt6dcz1/ca/precision-slideway-grinding-inc
[14:43:46] <FinboySlick> archivist: That one is is 1565km away if I'm driving.
[14:44:05] <archivist> just down the road!
[14:44:10] <FinboySlick> Might make it around 1000km by plane if I build an airport.
[14:45:31] <FinboySlick> archivist: I do have half a mind to send it to a shop that could get everything squared up and straight though.
[14:45:41] <FinboySlick> If I can find one that is.
[14:46:54] <archivist> or get a copy of Machine tool reconditioning and applications of hand scraping and do it the hard way
[14:47:24] <FinboySlick> archivist: If I had an actual workshop, I would. This thing is in what used to be a bedroom.
[14:47:49] <FinboySlick> Building a real workshop is in the plans though.
[14:47:52] <archivist> my 5 axis is in a bedroom
[14:48:19] <FinboySlick> archivist: Got video of it?
[14:48:46] <tjb1> Anyone had the problem where linuxcnc wouldtn wake up?
[14:48:58] <FinboySlick> tjb1: Does it ever sleep?
[14:49:10] <tjb1> It might, Ill have to check
[14:49:14] <FinboySlick> I thought it was like that girl in "The Ring."
[14:49:16] <tjb1> I mean ubuntu it self
[14:49:20] <FinboySlick> Oh.
[14:49:59] <FinboySlick> Depending on your chipset, suspend to ram can get iffy. I imagine a RT kernel would make that worse.
[14:50:54] <tjb1> Looking suspend up now, seems like it is the problem
[14:51:11] <archivist> tjb1, I have seen that on a particular pc, I had to reboot and got into x rescue
[14:51:31] <archivist> but that hardware is now dead :)
[14:51:35] <tjb1> After I turned off lock at idle it wont turn back on
[14:51:42] <tjb1> Well it wont wake up and I have to restart it
[14:54:07] <tjb1> alright brb
[14:54:23] <archivist> FinboySlick, my videos were when it was still 4 axis and never show the whole thing
[14:54:43] <FinboySlick> archivist: Timidmill ;)
[14:55:08] <archivist> http://www.youtube.com/user/davethearchivist?feature=mhee
[14:56:21] <archivist> when it was at work http://www.archivist.info/cnc/stage7/
[14:57:10] <FinboySlick> That's about the same size as mine.
[14:57:34] <archivist> but uglier :)
[14:57:44] <FinboySlick> I'm betting straighter too ;)
[14:59:16] <FinboySlick> archivist: Question on the linear rails on your Z axis...
[14:59:23] <archivist> straightness was not too important at the time as it was made for just cutting a gear face, the X and Y slides are from a tool setting machine
[14:59:33] <FinboySlick> If you pop these off the rails, do you get a rain of ballbearings?
[15:00:01] <archivist> those are retained and dont fall out
[15:00:19] <FinboySlick> OK. That's a worry of mine if I do decide to take it appart and fix it.
[15:00:47] <FinboySlick> I don't have the little plastic inserts to slide in there if they aren't retained. But it seems like the same type of rails.
[15:02:34] <archivist> see the clinometer in the lower middle http://www.archivist.info/cnc/stage4/P2030011.JPG, that was used to set the Z axis rails vertical
[15:03:34] <FinboySlick> archivist: How precise are those?
[15:03:57] <archivist> resolution is a minute
[15:04:55] <archivist> biggest problem was the wooden floor moving when walking around the machine
[15:06:09] <FinboySlick> archivist: Yeah, I'll definitely get that too. First part of my workshop project is to setup a nice concrete slab for my machine(s). I plan to add a lathe at some point.
[15:06:17] <archivist> but it fell off the bench and broke the bubble, cost me £80 to get a new bubble for it
[15:06:43] <FinboySlick> Oh they work like bubble levers?
[15:07:08] <FinboySlick> Um... Not lever... 'Niveau' in french. I guess litteral translation is level?
[15:08:21] <archivist> http://www.ebay.co.uk/itm/Hilger-Watts-Precision-Clinometer-TB9008-1-with-case-/150655237207?pt=LH_DefaultDomain_3&hash=item2313c07c57
[15:08:35] <archivist> I never paid that much
[15:09:59] <archivist> you should be able to get something like http://www.ebay.co.uk/itm/HILGER-WATTS-8-Precision-Square-Block-Level-Machine-Level-/170707152364?pt=UK_Measuring_Tools_Levels&hash=item27bef06dec
[15:10:06] <archivist> for about £100
[15:13:08] <archivist> Im a sucker for measuring tools
[15:14:58] <FinboySlick> I like the good stuff too. Measures should never be ambiguous ;)
[15:16:09] <FinboySlick> What's the green machine in the back of your latest link?
[15:16:46] <FinboySlick> Back of a horizontal mill?
[15:16:51] <archivist> mikron hobbing machine
[15:17:36] <archivist> top left pic is in action http://gears.archivist.info/
[15:18:45] <archivist> it did not follow me home when I left grrrrr
[15:20:15] <archivist> full frontal http://www.archivist.info/cnc/works2008/P1010240.JPG
[15:39:31] <JT-Shop> yea some of the metering valves arrived

[21:07:29] <r00t4rd3d> PLINGS
[21:10:19] <tjb1> shhhh r00t
[21:14:50] <r00t4rd3d> its been silent in here for like 5 hours
[21:15:14] <Tom_itx> yeah until you came along and ruined it
[21:15:34] <r00t4rd3d> gotta keep them logs going
[21:15:34] <Tom_itx> nice good nap
[21:20:46] <tjb1> nap?
[21:45:40] <r00t4rd3d> http://i.imgur.com/mrAc4.jpg

[22:40:10] <r00t4rd3d> www.imgur.com
[22:40:21] <tjb1> Why?
[22:40:48] <r00t4rd3d> you can group you images into an album
[22:40:58] <tjb1> I can do that on facebook
[22:41:02] <r00t4rd3d> ffs
[22:41:33] <tjb1> Its easier to upload it to facebook from phone
[22:41:51] <r00t4rd3d> imgur has a phone app i think
[22:42:06] <tjb1> Just look at pictures and hush
[22:42:09] <r00t4rd3d> http://imgur.com/blog/2010/12/10/imgur-mobile/

[22:43:04] <r00t4rd3d> id rather shoot myself in the mouth.
[22:44:21] <tjb1> i cant download that at home
[22:46:26] <r00t4rd3d> "Theres no special link, all you have to do is visit imgur.com on your phone."
[22:47:19] <tjb1> Not gonna work at home :)
[22:48:08] <tjb1> Come take this thing apart and paint the rails for me
[22:48:45] <tjb1> and I cant upload to the website because I have an iphone
[22:49:32] <r00t4rd3d> However, there are a couple great Imgur apps for the iPhone that support uploading, and they can be found simply by browsing the iTunes store.
[22:49:58] <r00t4rd3d> yawns.
[22:51:46] <tjb1> tjb1: i cant download that at home
