[00:28:32] <uw> Mach3 users: do you have any reason for using it over linuxcnc?
[00:28:52] <uw> I'm kinda new to this but have been using linuxcnc for about 2 weeks and think it works great
[00:36:57] * roycroft would suspect a slight bias towards linuxcnc in present company
[00:45:07] <cylly2> hmmm
[00:45:20] <Loetmichel> mornin'
[00:45:46] <Loetmichel> there ARE some features I am missing in linuxCNC
[00:46:15] <Loetmichel> ... like direct use of HPGL for milling
[00:46:34] <Loetmichel> (like in PCNC-Dos)
[00:47:21] <Loetmichel> or the Wizards for pockets and such in mach3.
[00:48:06] <Loetmichel> nut over all i think linuxCNC is the best control soft there is at the moment
[01:15:29] <uw> mornin
[01:16:04] <uw> ok the pocketing feature. yea i use my dxf>gcode coverter for that
[01:16:31] <uw> im not sure what HPGL is, ill check that out in the am
[01:30:44] <Loetmichel> uw: plotter language
[04:04:48] <DJ9DJ> moin
[04:18:28] <micges> hi
[05:23:59] <alex_joni> hi
[06:05:46] <jthornton> dang I over slept
[06:39:38] <mk0> hiall. is there any information about christian kohloeffel, who wrote dxf2gcode? 2 years passed from last build, noone from http://code.google.com/p/dxf2gcode/ answers.
[06:51:43] <jthornton> wow!! he waited a whole 12 minutes!
[06:56:08] <jthornton> must have been a connection failure
[06:56:46] <mk0> no one knows?
[06:57:22] <jthornton> might be better to ask on the mailing list
[06:57:36] <mk0> okay. thanks
[06:57:47] <jthornton> you never know who is even watching the computer screen on the IRC at any given time
[06:58:17] <mk0> i understand, just using any chance)
[07:17:14] <Valen> is there a paticular issue your having?
[07:25:35] <mk0> yep
[07:29:32] <Valen> well generally if your having a problem, asking about said problem can lead to answers
[07:31:28] <Tom_itx> jthornton, one less nap for you today!
[07:31:42] <jthornton> does seem to work faster that way
[07:32:18] <Tom_itx> someone suggested i mount my tranformer at the top of my enclosure
[07:32:21] * jthornton doesn't see a nap looming on the horizon for today
[07:32:31] <Tom_itx> all i've ever seen is at the bottom
[07:32:54] <jthornton> sounds like a good plan for heat, bad plan if it fall off
[07:33:03] <Tom_itx> yeah my thoughts
[07:33:10] <jdhNC> mk0: was there a real question, or just a general inquiry into the known location of the author?
[07:33:20] <mk0> both
[07:34:16] <jdhNC> he is alive and well, living in a rural mountain top in nepal. He has forsaken computers and exists tending long haired goats.
[07:34:33] <mk0> about a difference between paths in foam cutting and milling (where there's Z axis)
[07:34:53] <Tom_itx> right where it should be
[07:34:58] <jthornton> goat beer?
[07:35:00] <mk0> jdhNC, are you seriously?
[07:35:32] <Tom_itx> it was believeable
[07:35:35] <Tom_itx> so i'd say yes
[07:35:50] <jdhNC> mk0: would it be more or less relevant if it were true?
[07:36:05] <jthornton> plausible yes
[07:36:20] <mk0> well, he disappeared so suddenly...
[07:37:09] <mk0> jdhNC, anyways, do you know something real?
[07:38:11] <mazafaka> Hah. it's funny that listetning to Metallica's 'Enter Sandman' me, being foreigner, used to hear in different choruses 'Extend life / In denying / Take my hand / We'll go to the Neverland.' And 'Don't/ Waste time / Messing around / In yellow tie.' And native English people used to misheard alot, too. But studying for an IELTS test for foreigners really makes you know English, and its listeting part is so hard for me...
[07:39:54] <mrsun> shouldnt foam grind quite well insted of using milling cutters?
[07:40:03] <mrsun> feels like the finnish should be alot better atleast =)
[07:40:22] <mazafaka> E.g. http://www.youtube.com/watch?v=3-E6p43LP88
[07:41:26] <jdhNC> mk0: no clue.
[07:41:47] <jdhNC> but, if you have an issue with it, you might ask about that and see if anyone else knows.
[07:43:26] <mazafaka> mrsun: Today used pneumatic grinder to create blades for machine which crushes plastics. Planned to use plasma router and 2.5D milling machine, used plasma and grinder instead. Grinding wastes time, but works for hard materials., I think
[07:44:16] <mrsun> mazafaka, im talking about foam, that is the pink or blue one for insulation =)
[07:44:18] <mrsun> in cnc machines
[07:44:23] <mrsun> for example lost foam castings
[07:46:36] <mazafaka> I used cutting disk for metal on angle grinder to carefully cut thick pieces of wood. Some people on Internet who use dremel with self-made attachments can hurt themselfs in an obvious way, I wander about this all, how not to be careful whatever you do.
[07:49:41] <mazafaka> Also, only little angle grinders (disk diameter about 125 mm) are safe, big angle grinders with diameter of 230 mm or 10 inches are machines of death, and outer surface of huge cutting disk on such big angle grinders is usually wasted, so you make it fine again using angle grinder against the concrete floor
[07:50:11] <Valen> depends on what you are doing
[07:51:06] <jdhNC> I have a 100mm angle grinder I use may be once every other year
[07:51:07] <Valen> for some things a 10" grinder is the way to go
[07:51:37] <jdhNC> and a 200mm one I used once (with a buffing pad on my boat) that I will never use again.
[07:52:02] <jdhNC> it sucked bad enough with the buffing pad that I never want to see what a grinding wheel would do with it.
[07:53:01] <mazafaka> yeah, but we could hurt ourselfs on a regular dismantling of equipment or pipes or sewage system. but when you need to get through thin layer of material, have to use big angle grinder
[07:55:58] <mazafaka> especially when they change the knobs and you do not pull the grinder but rather keep it far while it tries to move to your side. "I am not like the ones who like the sparks flying onto them," they say. Hah, people who never really worked hard ever...
[07:57:22] <mazafaka> I have 125 mm Makita, about 10000 RPM and use it alot with the mask and wire brush, cutting disks for cleaning of MIG welding traces on thick steel
[07:58:14] <mazafaka> E.g. it's easy to carefully clean gas tank surface from welding with small cutting disk, than with the use of grinding wheel
[07:59:48] <mazafaka> s// on thin steel like gas tank
[08:52:26] <Loetmichel> re @ home
[09:03:34] <mazafaka> so http://3.bp.blogspot.com/-xgs2N2RKqfI/TmDTF8n536I/AAAAAAAAHis/p7zOXUh0IdY/s1600/Get%2Bon%2BParty%2BBus%2BNOW.png, Loetmichel
[10:19:29] <Gromits> We have a camera mounted next to a spindle. We want to put two buttons in a pyvcp panel. Move camera to tool, and move tool to camera. These buttons just move a fixed distance. I am having trouble getting it to work. Here is what I have configured...
[10:20:50] <Gromits> Taking just one of the buttons: in .ini I have three MDI commands configured. I have MDI_COMMAND = G91, MDI_COMMAND = G0 X-3.5 Y0.3, MDI_COMMAND = G90
[10:21:32] <Gromits> In custompanel.xml I have the halpin defined (tool-to-camera) and the button appears in the panel as it should
[10:22:35] <Gromits> in custom_postgui.hal I have: net remote-tool-to-camera pyvcp.tool-to-camera halui.mdi-command-00 halui.mdi-command-01 halui.mdi-command-02
[10:23:28] <Gromits> I home the machine, move to my point and touch off ALL. I then push the button and the head moves a tiny bit, but not the values I have configured.
[10:24:48] <Gromits> What am I missing?
[10:26:18] <JT-Shop> you will want to do that in a subroutine Gromits
[10:26:36] <JT-Shop> you can only run one mdi command at a time iirc
[10:26:41] <Gromits> ah
[10:27:03] <Gromits> so can I define a subroutine in an MDI_COMMAND line in the .ini?
[10:28:36] <JT-Shop> yep, make a named file with your sub in it like the manual says and use o<myname> call in the MDI
[10:29:04] <JT-Shop> if you don't have a file loaded the MDI command will fail
[10:29:17] <JT-Shop> can be a file with one line M2
[10:29:54] <JT-Shop> wanna know how many days it took me to find that out?
[10:30:06] <jdhNC> the sub could also reset g90 at the end
[10:30:41] <Gromits> do you happen to have a pointer to the manual on this?
[10:30:56] <Gromits> I don't really want to have the requirement to load a file.
[10:31:06] <Gromits> Can the button load a file?
[10:31:32] <Gromits> But I don't want that, because the user MIGHT have their own file loaded, or might not;;; :-(
[10:32:21] <jdhNC> there is a gladevcp example that has a button that runs a sub
[10:32:57] <Gromits> I thought about using Glade, but this install already has a pyvcp panel...
[10:33:17] <JT-Shop> to fix that undocumented feature you will have to change the code for Axis I think
[10:33:40] <JT-Shop> Gromits: which documentation are you seeking?
[10:34:12] <Gromits> in reference to your comment above: "...sub in it like the manual says and use o<myname>..."
[10:34:22] <JT-Shop> ri
[10:34:34] <JT-Shop> http://linuxcnc.org/docview/html/gcode/o-code.html
[10:34:44] <Gromits> thanks!
[10:34:47] <JT-Shop> np
[10:35:33] <Gromits> so that has to be called from within an ngc file, or are you just saying there is a "feature" that requires a ngc file to be loaded
[10:35:35] <Gromits> ?
[10:36:00] <JT-Shop> I was rather hoping to spark someones interest in removing that undocumentet feature...
[10:36:13] <Gromits> :-)
[10:36:20] <JT-Shop> no, you can not execute a MDI command without some file loaded
[10:36:27] <JT-Shop> try it and you will see
[10:36:39] <Gromits> I'll take your word for it.
[10:37:11] <JT-Shop> put OPEN_FILE = "" in the [DISPLAY] section then try and run a MDI command
[10:37:28] <Gromits> I may try to convert the panel to glade and try it that way.., perhaps that same "feature" is not there...
[10:37:49] <JT-Shop> it's an Axis "feature"
[10:38:06] <Gromits> hmm, so it may still be there if I use glade... :-(
[10:38:07] <JT-Shop> has nothing to do with pyvcp or glade
[10:38:53] <jdhNC> so the work around is trivial and almost nobody would trigger the problem anyway?
[10:39:21] <Gromits> work around being to load a file?
[10:40:40] <jdhNC> if you started with a canned install or generated config, it loads a file at startup anyway
[10:41:35] <Gromits> Ok. I guess we could do that..
[10:43:00] <jdhNC> echo M2>~/linuxcnc/nc_files/startup.ngc then have your .ini OPEN_FILE = "startup.ngc" ?
[10:45:46] <JT-Shop> jdhNC: well anyone that does not want a splash file loaded will have a huge chance at finding it
[10:46:12] <jdhNC> right. I don't want a splash file, but not bad enough to find the line in the INI and change it (yet)
[10:46:26] <JT-Shop> be better if that feature was not there as it serves no use
[10:46:55] <JT-Shop> I assume it is left over from before EMC had subroutines
[10:47:04] <jdhNC> looks like a buglet that hasn't annoyed anyone enough to fix.
[10:47:19] <JT-Shop> or left over from before you could run named subs
[10:47:52] <JT-Shop> yea, it cost me 3 days of lost work trying to figure it out...
[10:48:26] <JT-Shop> it annoyed me enough, just a bit short on the skills to fix it or even find it
[10:48:31] <JT-Shop> and I looked
[10:48:38] <Connor> What we talking about ?
[10:49:10] <JT-Shop> <JT-Shop> if you don't have a file loaded the MDI command will fail
[10:49:24] <Connor> Ah, Nice.
[10:49:37] <JT-Shop> yea
[10:50:09] <JT-Shop> if the MDI command is o<mysub> call
[10:50:36] <JT-Shop> something in the code requires a file loaded to execute a subroutine
[10:51:08] <Connor> That's crazy.
[10:53:46] * Gromits goes off to learn from the mistakes of others by repeating them himself.
[11:02:25] <JT-Shop> it's not crazy but must be a left over check when subs must be run in a file
[11:06:25] <JT-Shop> lunch time, anyone want the other half of my jam sandwich... I only get 1/2
[11:22:07] <Jymmm> JT-Shop: I tried "pumping" water with the Bimba. Even when I plugged one end (pseudo check valve) or the other end, and it didn't matter if it was on the up or down stroke, all I could ever do is pump from A to B, and from B to A.
[11:22:33] <JT-Shop> Jymmm: you only use one port to pump
[11:22:57] <JT-Shop> two check valves on each side of a T
[11:26:00] <Jymmm> JT-Shop: No matter what I did, It would only move back and fourth, If I "checkvalved" the output, It would have too much pressure to push on the down stroke.
[11:27:07] <JT-Shop> Jymmm: you don't understand what I'm saying
[11:27:30] <JT-Shop> you only use one port, say the one opposite the rod end for full volume
[11:27:39] <JT-Shop> you screw a T into that port
[11:27:55] <Jymmm> k
[11:28:11] <JT-Shop> you screw a check valve on each end of the T so one checks during sucking and the other checks during discharge
[11:28:34] <Jymmm> and what do I do with the other port?
[11:28:38] <JT-Shop> the second port is simply vented
[11:29:05] <Jymmm> But it ejects water out of it on the up stroke.
[11:29:22] <Jymmm> (all of this is of course once prmed)
[11:30:25] <JT-Shop> how did the water get in there?
[11:31:38] <Jymmm> Well, I tested this just by having two cups, one with water in it. but didn't have the Tee setup. I'll try with that once I find real checkvalves.
[11:32:45] <JT-Shop> it would be the same as putting the end in the cup of water and pulling the rod out then take it out and look in the port and push the rod in
[11:34:19] * JT-Shop heads to town to take the MIL to physical torture for an hour
[11:34:54] <Jymmm> JT-Shop: Before of Pecker Checkers with gloves!
[11:34:58] <Jymmm> Beware
[11:39:08] <tjb1> Hello channel lurkers
[11:39:16] <jthornton> I'll draw you a stick picture when I get back if you can't grasp the idea
[11:39:50] <Jymmm> JT-Shop: I get it now, thanks. Just need checkvalves and a tee now =)
[11:40:10] <jdhNC> you want to pump water by stroking a bimba air cylinder mechanically?
[11:41:54] <jthornton> it is a common way to meter fluids in the manufacturing industry
[11:44:58] <jdhNC> guess you could use a weight or spring and drive it with air
[11:48:30] <tjb1> Got a free tower :D
[11:57:11] <tjb1> Wow...
[11:57:25] <tjb1> The other 8020 distributor quoted me $16 higher than the other one
[11:57:34] <tjb1> The cut charge was even $.5 more
[11:59:52] <tjb1> Another distributor quoted me the same exact thing
[12:12:49] <IchGuckLive> hi all
[12:13:15] <tjb1> hello
[12:13:32] <IchGuckLive> pcw ? it worked today with the debounce of home-all
[12:13:40] <IchGuckLive> tjb1: hi B)
[12:13:49] <tjb1> Im just complaining about 8020 :)
[12:14:09] <IchGuckLive> 8020 fansise
[12:14:23] <IchGuckLive> O.O
[12:14:24] <tjb1> fansise?
[12:14:47] <tjb1> The extrusion company
[12:14:48] <IchGuckLive> 8020 i ordert today as a airfan size
[12:15:01] <IchGuckLive> oh aluprofiling
[12:15:15] <IchGuckLive> her in our region its minitec
[12:15:26] <tjb1> I would love to deal with someone else
[12:16:00] <IchGuckLive> where are you from
[12:16:21] <tjb1> Pennsylvania
[12:16:24] <tjb1> usa
[12:17:13] <IchGuckLive> http://www.minitecframing.com/
[12:17:13] <IchGuckLive> NY
[12:18:33] <tjb1> They all metric?
[12:18:43] <IchGuckLive> No idee
[12:18:51] <tjb1> Im guessing
[12:18:57] <tjb1> I need imperial :)
[12:19:03] <IchGuckLive> there are sizelists
[12:20:21] <IchGuckLive> pcw_home: it has worked with the debounce out to home-all in
[12:34:58] <Gromits> JT-Shop: thanks for the help, subroutines work, and I had forgotten we already load the default file (with Linuxcnc text) so that isn't an issue....
[12:39:49] <ReadError> tjb1
[12:39:53] <ReadError> you using some makerslides?
[12:40:01] <tjb1> No, too small
[12:40:40] <IchGuckLive> tjb1: are you mobile on off on off
[12:40:50] <tjb1> Mobile on off on off?
[12:41:08] <IchGuckLive> your irc goes of and on
[12:41:12] <tjb1> Am I on mobile because I keep joing and leaving?
[12:41:20] <tjb1> No I just keep closing computer because xbox is lagging :P
[12:43:21] <pcw_home> IchGuckLive: Glad it worked, a software solution is also better if you have a lot of machines
[12:44:50] <IchGuckLive> agree
[12:45:28] <IchGuckLive> pcw_home: i asked at the devels if ishoud make a forum post on this
[12:46:00] <IchGuckLive> or maybe its to trivial
[12:49:39] <IchGuckLive> WalterN: ? yelowstone
[12:50:05] <WalterN> I dont have any yellowstone
[12:50:23] <IchGuckLive> B)
[12:50:31] <jdhNC> my kids want me to engrave a rock for a kity headstone. How do you engrave a rock?
[12:50:53] <IchGuckLive> let me trunslate this
[12:51:41] <IchGuckLive> jdhNC: get a drill for stones and a drillbit also
[12:52:06] <IchGuckLive> short the drillbit with the harden blades to 1inch max
[12:52:26] <IchGuckLive> then just engrave your contour
[12:52:35] <IchGuckLive> onto the gravestone
[12:54:01] <IchGuckLive> jdhNC: http://www.youtube.com/watch?v=cLC_Ldv59Uk
[12:54:29] <jdhNC> Ich: V bit? or straight cutter?
[12:54:49] <IchGuckLive> the drillbit i 2blade V-shape
[12:54:58] <IchGuckLive> is
[12:55:24] <jdhNC> I'll look for one of those on the way home.
[12:55:29] <jdhNC> like a masonary bit?
[12:56:01] <IchGuckLive> WIDIA if this is the same in the USA for concreat drilling
[12:56:42] <IchGuckLive> jdhNC: 6mm in this diameter
[12:57:21] <jdhNC> maybe I'll talk them in to a chunk of aluminum.
[12:57:36] <IchGuckLive> B) :D
[12:57:54] <Jymmm> jdhNC: I laser engrave 12" black granite tile for such things.
[12:58:03] <IchGuckLive> let them do the CAD/cam so they will easy it out
[12:58:10] <Jymmm> jdhNC: hang on, getting pic
[12:58:33] <jdhNC> it woudl take months for them to do the cad
[12:59:00] <IchGuckLive> jdhNC: dont undersee your kidas
[12:59:37] <IchGuckLive> underestimate of cause
[13:00:15] <Jymmm> jdhNC: My uh, "Teddy Bear" on 12" granite tile http://i54.tinypic.com/k2mo7n.jpg
[13:00:32] <jdhNC> cool. Some pet.
[13:01:01] <Jymmm> jdhNC: Something I was toying with on some scrap tile... http://i51.tinypic.com/24z9hnc.jpg
[13:01:55] <Jymmm> jdhNC: I dont have a way of cutting the granite, or I could offer a smaller size.
[13:02:12] <jdhNC> also nifty. A laser is 3rd or 4th on my list.
[13:02:13] <Jymmm> 12, 16, and 18" is what I have
[13:02:38] <IchGuckLive> Jymmm: howmany wats
[13:02:42] <IchGuckLive> co2 ?
[13:02:51] <Jymmm> 30W CO2
[13:02:58] <IchGuckLive> nice
[13:03:03] <Jymmm> ty
[13:03:19] <jdhNC> perhpas a brick would be a good choice.
[13:04:01] <Jymmm> I can laser certain bricks.
[13:05:41] <IchGuckLive> Jymmm: laser homemade emc controled
[13:06:26] <Jymmm> IchGuckLive: http://www.assuredlaser.com.au/english/laser_systems/product_line/m300.html
[13:06:30] <IchGuckLive> laserhead or XY controled
[13:07:36] <Jymmm> No, it's not a galvo laser.
[13:07:56] <alex4nder> hey
[13:08:52] <IchGuckLive> Jymmm: i got 4 300mW galvo 32Kpps right behind me
[13:09:11] <IchGuckLive> for green laser show display
[13:09:11] <Jymmm> IchGuckLive: CO2 or YAG?
[13:09:19] <IchGuckLive> YAG
[13:09:35] <Jymmm> Huh? For machining or light show?
[13:09:46] <IchGuckLive> light show
[13:10:01] <Jymmm> why do you say it's a YaG ?
[13:10:26] <IchGuckLive> its a Neodyn
[13:10:49] <Jymmm> That's not YAG, a YAG laser can cut metal.
[13:10:57] <IchGuckLive> i do not know so far the increadians
[13:11:40] <Jymmm> a 50W YAG can cut titanium, a 2000W CO2 can steel
[13:12:41] <IchGuckLive> http://www.laserfx.com/Backstage.LaserFX.com/MediaLas-VV/PIC00035.jpg
[13:12:43] <jdhNC> we have three 5kw yag's sitting in a storage warehouse.
[13:12:52] <IchGuckLive> this are the mashines i got 4 of them
[13:13:29] <Jymmm> jdhNC: lat/lon of warehouse, guard rotation schedule, and code to alarm please =)
[13:13:44] <jdhNC> no alarms
[13:13:55] <jdhNC> door is open
[13:14:07] <jdhNC> guards are armed though
[13:15:01] <Jymmm> Nothing a lil NO couldn't resolve =)
[13:15:35] <Jymmm> aka aughing gas
[13:15:43] <Jymmm> laughing gas
[13:16:22] <Jymmm> jdhNC: you forgot the lat/lon =)
[13:17:08] <Jymmm> jdhNC: oh, why are they armed?
[13:17:49] <jdhNC> we have tons of enriched uranium
[13:18:06] <Jymmm> jdhNC: Oh, nm then
[13:18:31] <Jymmm> I don't need my pecker glowing in the dark on it's own!
[13:18:46] <jdhNC> uhm
[13:18:57] <alex4nder> wut
[13:19:11] <jdhNC> you are 1) on irc, 2) use linux, c) a cnc geek... what are the chances anyone but you will see it anyway?
[13:20:15] <jdhNC> oh c'mon, that was almost funny damnit.
[13:21:59] <Jymmm> jdhNC: 1) Phuk Ewe and the Cs-137 you rode in on. 2) geekness has nothing to do with thrroid gland, 3) Phul ewe and the Cs-137 you rode in on again! ;)
[13:23:21] <Jymmm> jdhNC: 5KW Yag?! That's just too much.
[13:23:45] <jdhNC> 2.5kw continuous
[13:25:32] <Jymmm> can you anodize already anodized aluminum?
[13:25:54] <jdhNC> isn't anodizing self-limiting
[13:26:01] <Jymmm> how so?
[13:26:15] <archivist> it is an insulator
[13:27:32] <Jymmm> Like If I get some things that are clear anodized and I want them red anodized as example. Or does it require prep work.
[13:27:50] <pcw_home> thats just dyeing
[13:28:07] <archivist> you teel them what colour at the time of anodising
[13:28:11] <archivist> tell
[13:28:25] <archivist> the dye it then seal
[13:30:29] <Jymmm> These only come clear, I'm just wanting a color "added", even if I have to have it done myself.
[13:31:41] <jdhNC> afaik, it will not take dye after it is sealed
[13:31:50] <archivist> anodising is porous till sealed, that is too late in the process
[13:32:45] <Jymmm> Bummer. Ok, thanks. I didn't think it was possible but thought I'd ask.
[13:46:04] <mrsun> man my "foot" for the countershaft is going to be B-E-A-U-T-ifuuullll =)
[13:58:42] <JT-Shop> tjb1: frameworld or mcmaster carr
[13:58:54] <tjb1> hmm?
[13:59:02] <JT-Shop> 80-20
[13:59:22] <JT-Shop> I used frameworld for my plasma, it was more cost effective
[14:01:03] <tjb1> got a price for 3030?
[14:03:42] <JT-Shop> full stick?
[14:05:57] <JT-Shop> http://www.frame-world.com/
[14:06:03] <tjb1> Whats a full stick?
[14:06:18] <tjb1> I couldnt find a price to save my life last time I was there
[14:06:22] <JT-Shop> iirc it was 20' or some meter thing
[14:06:44] <JT-Shop> hmm, I get it from Fluid Power
[14:06:44] <tjb1> what was 20'?
[14:07:11] <JT-Shop> a full stick was either 20' or some meter lenght I forget
[14:07:27] <JT-Shop> Standard 96", 144.75", 193.5" lengths.
[14:07:40] <tjb1> how much is 96"
[14:09:25] <JT-Shop> frame world doesn't seem to use the same part numbers as 8020
[14:09:37] <TekniQue> about 2440mm
[14:09:46] <JT-Shop> http://www.frame-world.com/catalog.htm
[14:10:26] <JT-Shop> LOL, he wants the price...
[14:11:40] <tjb1> ex-3
[14:11:46] <tjb1> where the hell is the price
[14:12:27] <tjb1> one of those cool websites that cant list a price
[14:13:30] <JT-Shop> let me see what the distributer quotes me for a stick
[14:14:04] <JT-Shop> tjb1: what is your location?
[14:14:10] <tjb1> 15757
[14:16:15] <JT-Shop> well lets see what he says... might take a bit for him to get back to me
[14:19:13] <JT-Shop> Yea! my 5/8-B duMONT showed up
[14:22:20] <tjb1> 5/8-b dumont?
[14:22:21] <Jymmm> JT-Shop: do we want to know what that is?
[14:22:33] <tjb1> sounds like a toy...
[14:23:18] <Jymmm> http://www.dumont.com/
[14:23:48] <tjb1> broach
[14:23:50] <tjb1> I win.
[14:24:15] <JT-Shop> yep almost it is the collared bushing for a broach
[14:25:10] <tjb1> excited over a bushing...
[14:25:37] <tjb1> get your computer working yet?
[14:27:17] <Gromits> Is there a command that can be put in a subroutine that asks Axis to reload a file?
[14:29:06] <jdhNC> Gromits: you want axis to reload a file after you do something in pyvcp/gladevcp?
[14:29:26] <Gromits> Yes. Touch off, specifically.
[14:30:03] <jdhNC> reloading after touch-off shouldn't do anything
[14:30:59] <Gromits> If you select Touch Off button that is already in Axis, after it touches off it automagically reloads the file.
[14:31:19] <Gromits> We have a touch off button in our panel and when we touch off we want to do the same
[14:31:52] <Gromits> The reason is that the new coordinates are somewhere else and if you don't reload the display is showing something that is not where you really are.
[14:34:24] <jdhNC> Connor: is this the same issue you had with axis not knowing you loaded a new file (via gladevcp)
[14:35:17] <Gromits> Yes, I was just wondering if there was hack to get around it by putting something in the subroutine to reload.
[14:35:28] <JT-Shop> tjb1: Scott will get me a price as soon as he gets back to the office
[14:35:45] <tjb1> alrighty, thanks JT-Shop
[14:36:04] <JT-Shop> andypugh created a pin in Axis to reload the file on the forum
[14:36:16] <Gromits> I think psha was going to look into the bug in Glade when he gets a chance..
[14:36:34] <andypugh> I might ask jepler about pushing it
[14:36:37] <Gromits> Did he have to modify Axis to do that?
[14:37:00] <andypugh> Yes, but it's a Python (interpreted) file, so not difficult
[14:37:13] <Gromits> Can you send me a pointer to it?
[14:37:26] <Gromits> We have lots of python in our config...
[14:37:59] <andypugh> http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=24&id=21008&limit=6&start=6#21025
[14:38:27] <Gromits> cool, thanks!
[14:38:45] <Connor> jdhNC: Sorry, not paying attention? What you referring too?
[14:38:57] <Gromits> this has been a pain for us.
[14:39:00] <jdhNC> nevermind:)
[14:39:17] <Connor> jdhNC: Oh don't do that to me. :(
[14:39:31] <Gromits> he was referring to the issue with the glade reload object not working (essentially)...
[14:40:17] <skunkworks> andypugh: is he sticking with linuxcnc? http://www.machsupport.com/forum/index.php/topic,21480.0.html
[14:41:01] <Connor> Yea. I found issues with gladvcp with load. It loads the file, but axis doesn't know it's changed.. you run the program, it runs the correct g-code, but axis thinks existing loaded file is what's running
[14:42:50] <andypugh> skunkworks: Interesting. I am sure he has been hanging about on the LinuxCNC forum for quite a while too.
[14:43:18] <andypugh> Yes, 2 years.
[14:43:57] <andypugh> He makes very pretty things. http://www.billooms.com/gallery.html
[14:46:18] <JT-Shop> wow
[14:47:14] <andypugh> I have no idea what software he uses. He seems to write his own, and this is clearly a Mac: http://www.billooms.com/Resources/COrnLathe/COrnLathe1.jpg
[14:49:07] <JT-Shop> the one hanging on the wall looks like an old dentist drill
[14:49:29] <JT-Shop> is that his cutter power?
[14:51:19] <andypugh> Seems to be.
[14:51:41] <andypugh> That's fairly traditional sort of power for watchmaking style lathes
[14:53:39] <andypugh> See http://www.lathes.co.uk/excel/page2.html for example
[15:01:16] * JT-Shop thinks that 4 peanuts for the afternoon meal will be enough... 6 peanuts seems to be too much
[15:01:46] <JT-Shop> that is an interesting machine
[15:02:23] <Connor> That's a wood lathe is it not ?
[15:05:44] <jdhNC> he seems to make (nice) wood stuff
[15:07:13] <andypugh> I think "nice" is an enormous understatement
[15:07:30] <andypugh> I thought Dewey's stuff was pretty, but I think I like his more
[15:08:00] <andypugh> I got my mini-keyboard today. I am impressed
[15:08:36] <andypugh> It's ideal for standing in front of a machine with and thumb-typing rather than balancing the keyboard on the milling vice.
[15:09:03] <andypugh> It has a backlight, and the Wireless widget can be stored inside
[15:09:22] <andypugh> I can see it living in a slot under the control cabinet
[15:09:26] <Tom_itx> got a pic of it?
[15:09:45] <Tom_itx> wireless kbd?
[15:10:33] <andypugh> http://www.amazon.co.uk/Wireless-Keyboard-Removable-Adjustable-Touchpad/dp/B004TQL3YS/ref=sr_1_1?ie=UTF8&qid=1340135968&sr=8-1
[15:11:23] <Tom_itx> wonder what sort of battery life they get
[15:11:51] <andypugh> Don't know yet, but it is LiIOn and recharable with a USB lead
[15:12:14] <JT-Shop> cool
[15:12:17] <Tom_itx> heh wireless but left plugged in the usb port :)
[15:16:30] <tjb1> Any news JT-Shop
[15:18:12] <andypugh> I also won this on eBay recently. Now to decide what I wanted it for: http://www.ebay.co.uk/itm/110895732424
[15:26:10] <tjb1> Gah this enclosure is so close
[15:26:17] <tjb1> 12 inches long and the power supply is 11
[15:27:01] <Jymmm> andypugh: paperclip holder
[15:27:22] <andypugh> My only paperclip is non-magnetic
[15:27:52] <JT-Shop> tjb1: I assume he is on the road and when he gets back to the office he will e-mail me again
[15:28:09] <tjb1> Alright, did you get that laptop working?
[15:28:13] <Jymmm> andypugh: hdd eraser
[15:28:29] <JT-Shop> me, no
[15:29:56] <tjb1> http://www.ebay.com/itm/Steel-Enclosure-13-5-x-13-5-x-5-25-/360463616949?pt=BI_Electrical_Equipment_Tools&hash=item53ed4e4bb5#ht_2124wt_1413
[15:29:57] <tjb1> Hmm.
[15:30:58] <tjb1> would 1.250 on each side of the power supply be enough?
[15:31:52] <andypugh> I would have thought so.
[15:32:04] <andypugh> The datasheet probably specifies
[15:32:04] <Jymmm> thats an thin guage alarm control panel, you dont want that
[15:32:07] <tjb1> Well thats on the ends where the wires get hooked up
[15:32:34] <tjb1> :(
[15:32:40] <tjb1> where do you see wall thickness
[15:32:55] <Jymmm> I dont
[15:33:49] <Jymmm> I see the knockout on the left, the cheap hinges, and the hole for a cam lock.
[15:34:36] * roycroft just ordered a rack enclosure for his cnc controller computer
[15:35:35] <andypugh> Is there any way to block ebay searches from showing stuff from PLCCenter?
[15:35:35] <tjb1> How much
[15:35:47] <tjb1> try -plccenter
[15:35:57] <roycroft> $59, if you're asking about the enclosure i ordered
[15:36:05] <tjb1> share where you bought it
[15:36:05] <roycroft> 4u, shallow depth
[15:36:09] <roycroft> amazon.com
[15:36:09] <JT-Shop> andypugh: go to advanced search
[15:36:21] <Jymmm> roycroft: 4U ?! wth
[15:36:53] <Jymmm> roycroft: you said RACK, did you mean enclosure?
[15:37:02] <roycroft> http://www.amazon.com/gp/product/B001H968NQ/
[15:37:08] <roycroft> i said "rack enclosure"
[15:37:19] <roycroft> perhaps i should have clarified and said "rack mount enclosure"
[15:37:47] * roycroft offers his apologies for any miscommunication
[15:37:48] <Jymmm> roycroft: I dont think you'll be happy with that for CNC controller
[15:37:53] <roycroft> why not?
[15:38:04] <Jymmm> roycroft: The back panel isn't setup for connectors
[15:38:18] <Jymmm> roycroft: the front panel is for drives
[15:38:18] <roycroft> i'm not going to mount the other components inside that box
[15:38:21] <roycroft> it's just for the computer
[15:38:24] <Jymmm> ah
[15:38:39] <roycroft> i bought a cart the other day for mounting all the gear
[15:38:44] <Jymmm> k
[15:38:59] <roycroft> it's a nice cart, on big wheels, and room for about 20u or more of components
[15:39:01] <roycroft> 1.2m high
[15:39:06] <roycroft> but it's fairly shallow
[15:39:09] <Jymmm> roycroft: The only thing the 4u will really give you is full height PC PS
[15:39:13] <roycroft> so i needed the ultra-short rack enclosure
[15:39:25] <roycroft> the 4u cost less than the otherwise equivalent 2u
[15:39:33] <Jymmm> heh, figures
[15:39:36] <roycroft> and it also offers more room inside for air circulation
[15:39:41] <Jymmm> nobody wants them anymore
[15:39:42] <roycroft> i have plenty of rack space to spare
[15:39:49] <roycroft> so i don't mind getting the big clunker
[15:40:09] <roycroft> i'm thinking of getting a 2u enclosure for power supplies
[15:40:22] <roycroft> and perhaps a 1u enclosure if i'm going to use a gecko driver or something
[15:40:33] <Jymmm> no 1u
[15:40:36] <roycroft> i'll likely fab those components myself
[15:40:46] <Jymmm> you need the air, and 1u fans are EXTREMELY LOUD
[15:41:02] <Jymmm> 150000 RPM x4
[15:41:08] <roycroft> as loud as a spindle running at 20k rpm? :)
[15:41:16] <ReadError> roycroft: what driver ?
[15:41:16] <Jymmm> louder
[15:41:18] <roycroft> 150krpm?
[15:41:18] <ReadError> the g540 ?
[15:41:23] <roycroft> that's a pretty fast fan!
[15:41:31] <roycroft> that's what i'm considering, readerror
[15:41:36] <ReadError> thats what i got
[15:41:37] <Jymmm> roycroft: about 125dB each fan
[15:41:42] <ReadError> nice piece of hardware ;)
[15:41:48] <roycroft> 125dB is pretty loud
[15:42:07] <Jymmm> roycroft: hostname: banchee =)
[15:42:13] <roycroft> they're reasonably priced, get good reviews, and are common enough that if something happened i would not have to worry about sourcing a replacement quickly
[15:42:44] <Jymmm> roycroft: I could walk nto the datacenter near my rack blindfolded and tell you which cabinet was my box in =)
[15:43:06] <tjb1> i hate ebay
[15:43:52] <roycroft> i don't have a problem with ebay
[15:44:19] <tjb1> I hate wading through pages of the same thing
[15:44:29] <tjb1> And I cant get rid of it because then it will get rid of what I am looking for
[15:44:33] <roycroft> it's like anything else - as long as one knows how it works and one's expectations are reasonable it generally works as one expects
[15:45:25] <tjb1> Broken english is my problem
[15:45:31] <andypugh> tjb1: It's all in the search terms
[15:46:02] <tjb1> http://www.ebay.com/itm/Enclosure-Box-/280808721312?pt=LH_DefaultDomain_0&hash=item4161810ba0#ht_500wt_1413
[15:46:03] <roycroft> and you can use advanced search
[15:46:09] <tjb1> Thats cool…if it HAD A SIZE >:(
[15:47:02] <Jymmm> http://search.ebay.com/industrial enclosure
[15:47:04] <roycroft> send the seller a message
[15:47:17] <Jymmm> http://search.ebay.com/industrial+enclosure
[15:49:05] <JT-Shop> andypugh: did you see the pyvcp slider fix for inival?
[15:49:29] <tjb1> http://www.ebay.com/itm/USED-Robroy-Industries-Control-Box-Enclosure-CL1311HW-USED-/140732457796?pt=BI_Electrical_Equipment_Tools&hash=item20c44ee344#ht_1153wt_1180
[15:49:36] <tjb1> is that 13"x11"?
[15:50:00] <roycroft> or search on "nema enclosure"
[15:50:32] <roycroft> this one, for example, is rather nice:
[15:50:34] <roycroft> http://www.ebay.com/itm/RITTAL-AE1380-500-1380500-NEMA-4-enclosure-NIB-/200738728102?pt=BI_Electrical_Equipment_Tools&hash=item2ebcf5e8a6#ht_560wt_1091
[15:50:45] <atom1> JT-Shop, what was that acad lookalike cad package for linux? do you recall?
[15:51:03] <tjb1> Not for $140 roycroft
[15:51:23] <atom1> or maybe it was some other cad-alike program...
[15:51:46] <roycroft> it's a decent value at that price
[15:51:50] <roycroft> it may not be what you want to spend
[15:52:00] <roycroft> but it's nib, and a very nice enclosure
[15:54:20] <tjb1> Its very nice
[15:54:24] <tjb1> and an awesome size
[15:54:31] <tjb1> but I dont know if I want to pay that
[15:54:34] <roycroft> yeah
[15:54:39] <roycroft> nema 4 is waterproof, too
[15:54:54] <roycroft> which also makes it coolant spray proof and swarf proof
[15:55:19] <Tom_itx> haha i just got one of those off ebay for $22
[15:55:21] <tjb1> I dont need waterproof
[15:55:40] <roycroft> item number, tom_itx?
[15:55:59] <Tom_itx> http://www.ebay.com/itm/RITTAL-AE-1380-Painted-Steel-Enclosure-15-x-15-x-9-/180899383510?_trksid=m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D3%26po%3DLVI%26ps%3D63%26clkid%3D9024009551874549694&_qi=RTM1084479
[15:56:35] <tjb1> Give you 40 for it tom
[15:56:41] <Tom_itx> cost more to ship it than i paid but it was well worth it :)
[15:56:54] <Tom_itx> wound up around 45
[15:56:57] <roycroft> that looks like it's a decent deal
[15:56:58] <Tom_itx> but well worth it
[15:57:01] <roycroft> it's used
[15:57:12] <roycroft> but a little paint and filler material and it will look like new
[15:57:12] <Tom_itx> yeah it's used but i could care less
[15:57:25] <roycroft> used doesn't bother me either
[15:57:32] <roycroft> especially since i repaint all my stuff anyway
[15:57:46] <Tom_itx> one added hole for power was all i found on it
[15:57:58] <roycroft> i paint all my machining gear a hammered cobalt blue color
[15:57:59] <Tom_itx> and some screw mounting holes added in the interior plate
[15:58:13] <roycroft> and those are easy to fill if you don't need them
[15:58:13] <Tom_itx> and they painted it that putrid color
[15:58:31] <roycroft> the brand new rack mount enclosure i just bought will be painted before it goes into service
[15:58:32] <JT-Shop> atom1: no, it escapes me
[15:58:47] <roycroft> i wouldn't care if it were putrid pink from the factory
[15:58:51] <Tom_itx> JT-Shop, no big deal. i was just gonna load it and try it out
[15:58:59] <tjb1> http://www.ebay.com/itm/NEW-Rittal-Industrial-Control-Panel-Enclosure-KL1504-/160316682819?pt=BI_Electrical_Equipment_Tools&hash=item25539e7243#ht_500wt_1180
[15:59:05] <tjb1> What do you think of that
[15:59:06] <JT-Shop> did we hear about it here?
[15:59:08] <Tom_itx> roycroft, what do you do to fill the holes?
[15:59:19] <Tom_itx> JT-Shop, yes
[15:59:29] <Tom_itx> iirc you were the spokesperson for it
[15:59:30] <roycroft> for something like that i'd probably just weld the holes up
[15:59:47] <JT-Shop> you could search the logs for it
[15:59:53] <Tom_itx> i could :)
[16:00:00] <roycroft> body lead would work fine too
[16:00:02] <Tom_itx> once i get this box done i may
[16:00:03] * JT-Shop goes back to work
[16:00:24] <Tom_itx> i probably won't worry about the hole, i may use it and make it bigger for a fan mount
[16:00:25] <roycroft> but a few seconds with a tig welder would do a nice job
[16:00:32] <Tom_itx> it's in the right place for one
[16:00:36] <roycroft> that's even better
[16:00:42] <Tom_itx> all i have is mig
[16:00:43] <andypugh> It comes with a handy bit of DIN rail
[16:00:45] <Tom_itx> but still...
[16:00:49] <roycroft> repurposing a hole is better than welding it closed
[16:01:05] <Tom_itx> i got a short piece of din rail but probably won't use it

[16:01:32] <JT-Shop> roycroft: http://images.drillspot.com/pimages/9330/933004_300.jpg
[16:02:05] <Tom_itx> tjb1, that doesn't look like a hinged lid
[16:02:15] <tjb1> Why do I need hinged
[16:02:34] <Tom_itx> JT-Shop, yeah that would work too
[16:02:35] <roycroft> i've used those hole plugs before
[16:02:38] <roycroft> i generally don't like them
[16:02:39] <ReadError> tjb1: how big of a cnc you building?
[16:02:42] <Tom_itx> i'll just repurpose the hole
[16:02:45] <tjb1> http://www.ebay.com/itm/Vynco-N325031-Industrial-Control-Panel-Enclosure-/230676107103?pt=BI_Electrical_Equipment_Tools&hash=item35b55e0f5f#ht_1102wt_1180
[16:02:48] <roycroft> i'll put one in a breaker box
[16:02:48] <tjb1> That one is sexy
[16:03:03] <roycroft> but if i'm building a control box for something i'll try to do something different
[16:03:08] <ReadError> i got a utility box from lowes
[16:03:11] <ReadError> its pretty durable
[16:03:11] <Tom_itx> i have about 5 of those
[16:03:14] <ReadError> about 30$
[16:03:28] <ReadError> its like a super heavy fiberglass/plastic or something
[16:03:34] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/SBC/inside_control.jpg
[16:04:05] <roycroft> so i've been trying to sell an old radial arm saw
[16:04:10] <roycroft> i've been posting it on cl
[16:04:17] <Tom_itx> 5 or 6
[16:04:20] <tjb1> Only $84 for that one
[16:04:26] <roycroft> i started out asking $100, then $60, then $40, and now i'm down to $25
[16:04:29] <roycroft> not a single query
[16:04:42] <roycroft> i guess next thing is to put it in the barter section
[16:04:49] <andypugh> roycroft: eBay?
[16:04:53] <roycroft> and see if someone wants to do some lawn work or something
[16:05:07] <roycroft> i can't be bothered to crate it for shipping, andypugh
[16:05:16] <roycroft> and it would cost way more to ship than it's worth
[16:05:24] <roycroft> i guess i go to barter on cl
[16:05:45] <roycroft> and then if that doesn't work, i'll donate it to the local habitat for humanity and take a $100 tax write-off
[16:05:48] <andypugh> eBay as "collection only"
[16:06:10] <roycroft> it's funny how radial arm saws used to be such popular items, but now nobody wants them at all
[16:06:35] <roycroft> i've sold a lot of stuff on cl of late, and it's all gone well except for this saw
[16:06:37] <tjb1> deadly :P
[16:06:43] <roycroft> i anticipated the saw would be a tough one to sell
[16:06:56] <roycroft> i was very pleased with the sale of my 4x6 bandsaw
[16:07:03] <roycroft> i paid $50 for it at a garage sale about 10-15 years ago
[16:07:13] <roycroft> i used it all those years, until i upgraded to a 7x12
[16:07:17] <roycroft> and i sold it for $125
[16:08:12] <roycroft> i would say i got good value from it for the time i owned it
[16:21:06] <JT-Shop> andypugh: does the 7i78 work with LinuxCNC?
[16:23:12] <andypugh> They should all work
[16:24:17] <andypugh> Ah, and it undercuts some BoBs too.
[16:28:00] <PCW> JT-Shop wow sure hope babis' initval solution does _not_ get incorporated
[16:32:39] <tjb1> What size is this thing http://www.ebay.com/itm/USED-Robroy-Industries-Control-Box-Enclosure-CL1311HW-USED-/140732452682?pt=BI_Electrical_Equipment_Tools&hash=item20c44ecf4a#ht_1153wt_1180
[16:36:11] <PCW> easy enough to google (~13"x11"X6")
[16:37:27] <andypugh> It seems to make more sense to have an "invert" option for the scale thingy
[16:37:27] <tjb1> What site told you that
[16:38:11] <tjb1> Its not a stahlin
[16:40:29] <JT-Shop> PCW: why is that?
[16:40:58] <JT-Shop> andypugh: yes an "invert" pin would be better and less confusing
[16:44:02] <PCW> its was simple as it was
[16:44:49] <PCW> and mucking with the meanings of min and max is not good
[16:54:38] <DJ9DJ> gn8
[16:57:03] <andypugh> They could be labelled "top" and "bottom"
[17:03:10] <andypugh> What do I need to break a 300V 10A _DC_ circuit?
[17:03:27] <andypugh> Clearly the relay I tried to use wasn't up to the job.
[17:17:21] <ReadError> http://i.imgur.com/BmNUf.gif
[17:17:25] <ReadError> ARE YOU NOT ENTERTAINED?
[17:19:31] <JT-Shop> andypugh: a contactor over here is what we call them
[17:19:57] <andypugh> Are they happy breaking DC?
[17:20:09] <JT-Shop> let me look at the rating on one
[17:20:21] <andypugh> I can pick up one of these tomorrow, but is it right? http://www.tlc-direct.co.uk/Products/WYMESB20.html
[17:20:36] <tjb1> JT-Shop: :D
[17:26:48] <JT-Shop> seems they have an AC3 or AC1 rating but nothing about AC vs DC
[17:27:33] <andypugh> AC1 means inductinve, AC3 means starting motors and stopping them from full speed. AC means you can stop from part speed..
[17:27:34] <PCW> DC inductive loads make a nice arc welder so you need special DC contactors
[17:27:44] <andypugh> Sorry, AC1 means _non_inductive
[17:27:59] <andypugh> PCW: Yes, I spotted that
[17:28:00] <JT-Shop> there you go Andy
[17:28:49] <JT-Shop> http://www.eaton.com/Electrical/USA/ProductsandServices/AutomationandControl/MillControlProducts/DCContactors/index.htm
[17:29:10] <PCW> bigger ones have blowout coils
[17:29:16] <andypugh> This is the relay that connects the crowbar resistor across my capacitors
[17:29:19] <JT-Shop> mean looking beast
[17:30:09] <andypugh> Rather more serious than I want
[17:30:23] <tjb1> Hey Jt, any news?
[17:30:51] <PCW> But it should not normally open if theres voltage, maybe its a powerup/down sequence issue
[17:31:23] <tjb1> Hey Andy
[17:31:25] <andypugh> Yes, my finger bounced on the touchscreen, turning the machine on and off again rapidly
[17:32:09] <andypugh> I am thinking about moving the control into software..
[17:32:36] <andypugh> But at the moment it opens if there is power to the supply, and closes when the power goes away
[17:32:39] <PCW> if theres a spare contact maybe you can enable the AC contactor only when the dump relay is open
[17:33:38] <andypugh> That might be possible, though they are in the same box.
[17:33:55] <andypugh> Sorry, they are in different boxes, I mean.
[17:37:21] <PCW> no estop --> pilot AC power --> open dump relay --> dump relay pilot contact --> main AC contactor
[17:39:29] <tjb1> http://i.ebayimg.com/t/Vynco-N325031-Industrial-Control-Panel-Enclosure-/00/s/MTAyNFg2OTc=/$(KGrHqUOKpYE5c1DIrczBOeiyw0EfQ~~60_57.JPG
[17:39:34] <tjb1> Any thoughts on that one
[17:42:09] <PCW> If you wanted to get fancy, dump relay opening could also be qualified by DC below 30V or so
[17:44:40] <andypugh> I was hoping to avoid all fanciness.
[17:45:04] <andypugh> A prefer the very simple "power is off, dump relay closes"
[17:46:00] <andypugh> The simplest approach might be an inhibit timer in HAL.
[17:46:20] <PCW> Yeah a timer so you have a minimum off time
[17:46:56] <andypugh> That might also mean I can just replace the relay like-for-like
[17:47:23] <andypugh> As it should then only make with voltage applied.
[17:48:17] <andypugh> I will try that and see how it works out.
[17:48:30] <PCW> or sense the DC voltage (this does the same as the timer)
[17:49:51] <PCW> but a timer is simple and doesn't add new wires connected to nasty voltages
[17:54:42] <andypugh> Yes, that last bit was what I was nervous about.
[17:55:25] <andypugh> By the way, do any of my parameter-discovery cards have downloadable firmware?
[17:55:47] <PCW> all do
[17:55:58] <andypugh> OK.
[17:56:19] <PCW> only remote card without downloadable firmware is 7I64
[17:56:48] <JT-Shop> rewiring the phase converter went well... nothing exploded when I ran it
[17:57:04] <PCW> thats always good
[17:57:14] <andypugh> JT-Shop: I thought that was redundant now?
[17:58:25] <JT-Shop> it's still the preferred way to run the lathes
[17:58:56] <JT-Shop> I'm replacing the electrical cabinet on the generator now that the frame modifications are done
[17:59:49] <JT-Shop> for shit's and grins I replaced the tiny so cord from the 50a breaker with some 6-4 SO cord just to be sure voltage drop was not the issue
[18:00:29] <JT-Shop> 8 awg would have been better but I didn't have any laying about
[18:17:22] <andypugh> I wonder what firmware is on this 6i25? It appears to have 12 encoders.
[18:24:20] <micges> 7i77x2
[18:25:37] <andypugh> Possibly, though I would expect PWM too.
[18:25:47] <andypugh> I have no field power though.
[18:29:20] <andypugh> Time to hack an SATA Power connector to leach power from the motherboard :-)
[18:29:54] <PCW> 7I77 has no PWM
[18:30:13] <PCW> or rather the 7i77x2 config has no PWM
[18:30:39] <Jymmm> 8ga, jumper cables/ welding cbales
[18:31:15] <andypugh> PCW: Ah, it's analogout isn't it?
[18:31:25] <andypugh> They need field power to show up?
[18:31:38] <PCW> not the analog out
[18:32:42] <PCW> just the isolated digital I/O
[18:32:49] <Tom_itx> ok i got 3 separate transformer secondaries connected with .002v across their open wires. i think they are closely enough matched to connect them as one secondary. any thoughts?
[18:33:49] <PCW> since thats got to be less than the volts per turn I'd say go ahead
[18:34:03] <Tom_itx> it would save me 2 diode packs that way
[18:34:26] <Tom_itx> i had them combined after the bridge rectifiers originally
[18:35:18] <PCW> more load per bridge now...
[18:35:27] <Tom_itx> it's a 25A bridge
[18:35:45] <Tom_itx> the stepper drivers are only 7A x 3
[18:35:46] <roycroft> wow
[18:35:57] <roycroft> so the enclosure i ordered was supposed to ship in 3-5 days
[18:35:59] <Tom_itx> and i have them throttled back to 3.5 A
[18:36:07] <roycroft> and i just got a shipping notice and tracking number
[18:36:22] * roycroft wonders how much fun it's going to be to paint that thing
[18:36:36] <PCW> and they will only draw 3.5A when running at a fair clip
[18:37:10] <Tom_itx> what are the odds of one transformer shorting, taking the other 2 with it?
[18:37:17] <andypugh> W2 UP: Bingo!
[18:37:21] <Tom_itx> i can still wire it after the bridges...
[18:37:26] <Tom_itx> i'd just rather not
[18:38:04] <PCW> transformer failures are pretty rare unless overheated or wet
[18:38:48] <PCW> also a primary fuse /circuit breaker should catch this
[18:39:13] <roycroft> transformers also fail when they get hit by lightning
[18:39:15] <Tom_itx> any opinion whether to join them at the AC or after the bridges?
[18:39:22] <roycroft> and that's fairly common for power utility transformers
[18:39:25] <Tom_itx> i have enough bridges to go either way
[18:39:36] <roycroft> it hopefully doesn't apply in this situation, however
[18:40:01] <Jymmm> Tom_itx: id do it bfore
[18:40:08] <Tom_itx> reason?
[18:40:14] <PCW> lightning is pretty rare here
[18:40:21] <Jymmm> Tom_itx: filtering
[18:40:43] <roycroft> it's rare around here, too
[18:40:53] <Tom_itx> Jymmm, originally i had them wired after the bridges but i'm rewiring it now to stick in the control box
[18:40:55] <roycroft> well, it's common in the mountains
[18:40:59] <roycroft> but not in the valley
[18:41:08] <Tom_itx> and i decided to check the voltage differential while i was doing it
[18:41:15] <Tom_itx> .002 v isn't very much
[18:41:48] <Jymmm> JT-Shop: got a moment?
[18:46:38] <JT-Shop> back and forth, running the manual lathe
[18:47:02] <Tom_itx> maybe it's running you
[18:47:05] <roycroft> how quaint
[18:47:47] <roycroft> in my shop, though, "manual lathe" is redundant
[18:49:11] <JT-Shop> ain't nothing quaint about the Samson lathe
[18:51:08] <andypugh> PCW: Are the sserial ports on the same pins in the 7i77 software as the 7i76?
[18:51:42] <andypugh> If not, that would explain why I am not seeing much action from my 7i76 :-)
[18:53:17] <PCW> Different pinout so you can interchange (but the firmware tool works)
[18:53:27] <PCW> cant interchange
[18:53:35] <andypugh> Right. It works. :-)
[18:54:22] <PCW> dont write any 6I25 firmware or you cant get back...
[18:54:41] <andypugh> Can you elaborate?
[18:54:48] <andypugh> You mean 5i25 is OK?
[18:55:02] <andypugh> The card is currently claiming to be a 5i25 anyway
[18:55:05] <PCW> the firmware tool only knows 5I25s now
[18:55:08] <andypugh> ls
[18:55:19] <PCW> as does LinuxCNC
[18:55:21] <tjb1> My new electronics enclosure :) - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230676107103#ht_1102wt_1180
[18:56:11] <andypugh> Calling it a 5i25e might have been simpler?
[18:57:48] <jdhNC> tjb1: I got this one a few weeks ago: http://www.ebay.com/itm/400296596662
[18:58:04] <jdhNC> I could use a key for it though
[18:58:33] <tjb1> Wow you and tom are lucky
[18:59:19] <JT-Shop> well that came out nice a perfect fit
[19:00:50] <JT-Shop> btw, roycroft it is unethical, a crime against machinest of the past and unmoral to make a steam engine on a CNC
[19:01:55] <djdelorie> what if you're making a CNC steam engine?
[19:02:15] <Tom_itx> tjb1, no luck.. just persistence
[19:02:45] <tjb1> Or making a steam engine to power a generator to run your manual machines to make your hobby steam engine
[19:05:47] <andypugh> A steam-powered generator to run the VMC would be marvellously anachronistic.
[19:07:17] <JT-Shop> well that is a different story djdelorie
[19:07:35] <djdelorie> nothing wrong with robots building more robots, even if steam powered :-)
[19:07:50] <PCW> "Calling it a 5i25e might have been simpler?"
[19:07:51] <PCW> Yeah except all PCI cards are 5xxx and PCIE are 6XXX
[19:09:00] <PCW> 6I25 firmware also expects a 66MHz PCI bus
[19:09:50] <PCW> (so needs different jumper settings)
[19:13:49] <tjb1> Is it worth it to pay $35 more to get a brand new Rittal enclosure of the same size?
[19:15:21] <Tom_itx> that's $35 worth of bar stock you could machine
[19:15:39] <tjb1> Im thinking its going to be 50 bearings I need to make the linear carriages
[19:25:07] <andypugh> That flashing tool is quite nice, isn't it?
[19:25:17] <andypugh> (It's all working now)
[19:25:40] <Tom_itx> oh for the mesa cards?
[19:26:03] <andypugh> Would a param-discovery 8i20 return any information about, for example, the max-current eeprom setting?
[19:26:20] <andypugh> Or are they different sorts of things?
[19:36:38] <andypugh> Something to worry about another day.
[19:36:43] <andypugh> Night all.

[21:12:46] <Jymmm> Workers Comp for carpal tunnel syndrom??? http://www.youtube.com/watch?v=3p3c9mbaZkQ&feature=related
[21:29:58] <roycroft> what about it, jymmm?
[21:31:37] <roycroft> i'm actually fighting with my insurance company right now over a case of trigger finger
[21:31:59] <roycroft> they insist that any trigger finger or carpal tunnel condition is work-related, and that it must be claimed through worker's comp
[21:32:03] <roycroft> and they denied my claim
[21:32:10] <roycroft> i'm in the midst of the appeal process
[21:44:13] <jdhNC> medical care or disability?
[21:46:59] <roycroft> medical care
[21:47:12] <roycroft> i'm not claiming disability
[21:47:15] <roycroft> i just wanted it fixed
[21:48:20] <roycroft> and the treatment i got has improved the situation considerably
[21:48:50] <roycroft> i was experiencing severe pain on the inside of my elbow from the condition, and my doctor has completely eliminated that
[21:49:11] <roycroft> the pain was such that i had lost most strength in that hand
[21:49:34] <roycroft> the tendon is still triggering in the finger itself, but it's tolerable
[21:49:41] <roycroft> and it seems to be getting better on its own
[21:50:02] <roycroft> i wanted to see if that would happen before getting injections or surgery to correct it
[21:58:55] <Jymmm> avoid the knife as much as possible
[22:04:37] <tjb1> I had a pilonidal cyst I had to go to a clinic and get it cut open without anything
[22:04:54] <tjb1> Well they did poke me with a needle back there…damn needle hurt worse than them cutting it
[22:05:49] <r00t4rd3d> so you had a giant zit on your ass?
[22:06:02] <r00t4rd3d> lol
[22:06:12] <tjb1> I guess
[22:06:22] <tjb1> It was filling up…damn thing hurt so bad I couldnt sit down
[22:06:37] <tjb1> They took a cup of black stuff out of it
[22:07:36] <roycroft> that's my plan
[22:08:25] <jdhNC> http://tinyurl.com/7c6stxs
[22:08:34] <jdhNC> one of Connor's stepper covers
[22:09:36] <tjb1> piece on the back that comes up over?

[22:16:11] <tjb1> Anyone notice the problem in the second paragraph?
[22:23:02] <roycroft> you mean the part about insuring your tools instead of ensuring that they're available? :)
[22:24:11] <roycroft> or the metric-imperial bit?
[22:25:33] <tjb1> metric-imperial...
[22:25:45] <tjb1> im gonna buy 1 and make the other 7 i need
[22:26:01] <roycroft> insure/ensure mixups are one of my biggest language peeves
[22:26:11] <tjb1> Everything is metric because the bearings are metric
[22:26:19] <roycroft> and i don't get why people can't get it straight
[22:26:59] <roycroft> that's fine
[22:27:07] <roycroft> just pull out your 12mm wrench
[22:27:17] <tjb1> Well…the bolts and holes for said bolts are metric
[22:27:26] <tjb1> The part is dimensioned in imperial
[22:27:37] <tjb1> as well as every other hole is imperial lol
[22:27:43] <tjb1> the set screw is probably imperial...
[22:28:05] <tjb1> he is sneaky with his cad files
[22:28:19] <tjb1> he scales them some odd number then manually dimensions certain parts of it
[22:28:43] <roycroft> why would he do that?
[22:28:50] <roycroft> trying to keep folks from copying?
[22:29:28] <tjb1> Dunno
[22:29:38] <tjb1> I just scale them back and get what dimensions I need...
[22:30:34] <tjb1> Gonna be honest though, I am too lazy to make the rack and pinion drive so I will be buying those from him :P
[22:33:58] <roycroft> my project has sure changed since i started
[22:34:16] <roycroft> i was going to by a zen toolworks router kit and put that together
[22:34:31] <roycroft> i decided instead to just cnc my mill-drill
[22:34:38] <tjb1> What the hell is this - http://i.ebayimg.com/00/s/MzIyWDUwMA==/$(KGrHqZHJCIE8mU5sorBBPPStEK69!~~60_12.JPG
[22:34:48] <tjb1> How hard is that to do?
[22:35:31] <roycroft> is that a cable being sold specific for cnc controllers?
[22:35:42] <roycroft> specifically
[22:36:00] <tjb1> No I searched parallel cable on ebay and thats all that comes up
[22:36:02] <jdhNC> uhm.. how old are you?
[22:36:22] <roycroft> well it's not difficult at all to make that cable
[22:36:36] <roycroft> the centronics crimp tool that you need for it will cost you several hundred dollars, though
[22:36:54] <tjb1> I dont need that centronics end
[22:37:18] <roycroft> for a cnc controller you need a db-25 to db-25 cable with all pins connected through
[22:37:36] <tjb1> Guess I will just buy it from ahren
[22:37:43] <tjb1> Only $11 there
[22:37:45] <roycroft> a typical serial cable that uses db-25 connectors will use nine pins at most
[22:40:51] * roycroft decides to give an attempt at a heekscad/heekscnc another go tonight
[22:40:55] <Connor> monoprice.com has CHEAP cables.
[22:41:31] <Connor> m25-db to f25-db are normally called serial or parallel extension cables.
[22:41:34] <tjb1> they also have like a 3 month shipping time :p
[22:41:54] <Connor> tjb1: Since when? I always order i get stuff quick
[22:42:03] <tjb1> Last time I ordered it took forever
[22:42:11] <jdhNC> there are ieee1284 a-a cables on ebay
[22:42:20] <Connor> I uses USPS Priority when Possible.
[22:42:37] <Connor> jdhNC: I have to say, those stepper covers turned out nice.. :)
[22:43:05] <jdhNC> yep. Got Y mounted now.
[22:43:11] <roycroft> yes, but that's not what he wants, jdhnc
[22:43:38] <Connor> jdhNC: Any clearance issues with the connector or radius of the cable bend ?
[22:43:43] <roycroft> oh, wait, that standard is the interface standard, not the connector standard
[22:43:44] <roycroft> sorry
[22:43:45] <tjb1> How can you tell if all are wired?
[22:44:00] <jdhNC> ieee 1284 specifies all wired
[22:44:01] <Connor> tjb1: Read the specs.
[22:44:17] <jdhNC> you want centronics? There are lots of those also
[22:44:18] <tjb1> Thanks jdhNC
[22:44:41] <uw> roycroft, how do you like heekscnc?
[22:45:06] <tjb1> Arent much cheaper on ebay, $8 for a 6'
[22:45:06] <roycroft> uw: i played with heekscad a wee bit a long time ago
[22:45:24] <roycroft> i'm more interested in the cam code, which i've never used
[22:45:27] <jdhNC> Connor: Y clearance is pefect
[22:45:41] <roycroft> i'm attempting to install it now, but the installation notes do not seem to reflect reality
[22:45:57] <roycroft> and i've virtually no linux experience, so it's not going that well at the moment
[22:46:05] <roycroft> my unix/bsd experience does not seem to be very helpful
[22:46:08] <Connor> http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10210&cs_id=1021001&p_id=384&seq=1&format=2
[22:46:08] <jdhNC> I guess I'll run the cable around the lip of the chip tray
[22:46:16] <uw> roycroft, i've never used it, but interested in comparing different cnc programs right now because I'm new and dont want to get skilled at looking a terrible system.
[22:46:30] <uw> ahh that was going to be my next question
[22:46:33] <uw> how does it work with linux
[22:46:53] <uw> looking = learning
[22:47:09] <roycroft> my recommendation, coming from one who has never operated a cnc machine before, is to learn to hand-code your gcode at first
[22:47:09] <tjb1> Need a m to m connor
[22:47:10] <jdhNC> connor: your x limit doesn't reduce Y travel?
[22:47:34] <roycroft> before you start using a cam program
[22:47:38] <Connor> http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10210&cs_id=1021001&p_id=380&seq=1&format=2
[22:47:45] <Connor> jdhNC: No.
[22:47:59] <Connor> Has enough clearance.
[22:48:11] <tjb1> Thanks Connor
[22:48:14] <roycroft> it seems to me it would be difficult to evaluate cam software if you can't parse the gcode it generates
[22:48:37] <jdhNC> that's the easy part
[22:48:45] <Connor> roycroft: Not really. You can evaluate allot in just the ease-of-use.
[22:48:54] <jdhNC> getting it to generate anything is a pain in theass generally
[22:49:23] <roycroft> isn't correct, efficient machining and compatibility with your cnc controller software more imporant than ease of use?
[22:49:36] <tjb1> Does Ubuntu/LinuxCNC support touchscreen?
[22:49:42] * roycroft is not arguing, - just asking questions
[22:49:43] <roycroft> yes!
[22:49:51] <Connor> tjb1: Yes
[22:49:51] <roycroft> i have touchy working great!
[22:50:08] <tjb1> Where did you get that monitor :)
[22:50:19] <roycroft> i got my last one at the goodwill
[22:50:22] <roycroft> for $12
[22:50:25] <Connor> roycroft: Yes, it is. But, I first want easy-of-use. No need in evaluating the gcode capability if I can't use the damn thing.
[22:50:29] <tjb1> You found a touchscreen monitor at goodwill
[22:50:32] <roycroft> yup
[22:50:36] <roycroft> it is a dell
[22:50:41] <roycroft> but elo touchscreen on it
[22:50:51] <roycroft> took me all of about 2 minutes to get it working when i got it home
[22:51:00] <roycroft> 15" lcd
[22:51:10] <Connor> I have a friend who works @ elo. going to see if he can hook me up. :)
[22:51:17] <roycroft> i also have a 17" lcd elo touchscreen that i got on ebay
[22:51:23] <roycroft> that one was $40
[22:51:34] <roycroft> but it was pulled from a kiosk, so it doesn't have a back or a stand
[22:51:48] <roycroft> it's going in a custom cabinet console anyway, so that did not matter to me
[22:52:12] <roycroft> there are more of those dell touchscreens at the goodwill
[22:52:19] <roycroft> maybe i should buy them up and ebay them
[22:53:14] <tjb1> Go grab one and ship it to me :)
[22:53:37] <tjb1> Is Elo an actual screen or something that goes over an existing monitor…or both
[22:53:49] <roycroft> i have an elo crt touchscreen monitor i bought brand new about 15 years ago for some god-awful price like $800
[22:53:51] <roycroft> it's only 15"
[22:54:05] <roycroft> i used it for development of some web-based kiosk software
[22:54:16] <roycroft> it's sitting in my attic
[22:55:42] <tjb1> http://www.ebay.com/itm/ELO-ENTUITIVE-19-TOUCHSCREEN-LCD-MONITOR-ET1915L-POS-TOUCHSCREEN-WITH-STAND-/271001881970?pt=Computer_Monitors&hash=item3f18f88d72#ht_2037wt_1180
[22:56:11] <roycroft> that's not bad
[22:56:17] <roycroft> it's awfully big for a cnc controller
[22:56:46] <roycroft> but i have a small shop
[22:56:55] <tjb1> http://www.ebay.com/itm/Elo-1547L-8CWE-15-Touch-Screen-Monitor-Black-/140753974104?pt=Computer_Monitors&hash=item20c5973358#ht_1918wt_1413
[22:57:04] <tjb1> Is that a plug and play?
[22:57:48] <roycroft> that's kind of like the 17" one i got
[22:57:57] <roycroft> it looks like the touch interface is rs-232, not usb
[22:58:10] <roycroft> which is no problem as long as you have an rs-232 port available on your computer
[22:58:25] <tjb1> http://www.ebay.com/itm/ELO-1545L-8SWC-1-15-Touchscreen-Computer-Monitor-Black-/140768179642?pt=Computer_Monitors&hash=item20c66ff5ba#ht_2680wt_1413
[22:58:32] <tjb1> that one uses a standard power jack
[22:59:17] <tjb1> rs232 would be the IOIOI?
[23:00:34] <tjb1> What is the headphone plug for
[23:05:20] <uw> roycroft, i've used linuxcnc and have had to edit gcode manually
[23:05:47] <uw> just looking for other systems incase i started doing the wrong thing with linuxcnc
[23:06:18] <roycroft> i'm considering solidworks/solidcam, but i don't have the cash for that right now
[23:06:46] <roycroft> and my most immediate need is to mill some pcbs, for which i'll use pcb-gcode
[23:07:11] <uw> excellent thats really i want to do too
[23:07:31] <roycroft> geda/pcb-gcode/linuxcnc is the path i'm taking
[23:08:25] <roycroft> but since i'm converting my miller and not building a dedicated pcb routing machine i need some other, general-purpose gcode-generating software
[23:11:45] <uw> wow i havent used that before
[23:12:06] <uw> ill have to try out geda
[23:12:30] <uw> i am using cadence and it's ok, but am looking for a gpl solution
[23:12:35] <roycroft> i'm still learning it, but it seems to work really well
[23:14:00] <tjb1> Hey roycroft
[23:14:19] <roycroft> yes?
[23:14:24] <tjb1> http://d3d71ba2asa5oz.cloudfront.net/43000231/images/et1515l%20(2).jpg
[23:14:34] <tjb1> What would the power jack be used for?
[23:14:58] <roycroft> possibly 12vdc directly into the display?
[23:15:11] <tjb1> I do see 12v 2.5A listed below
[23:15:16] <tjb1> Alternate power source then?
[23:15:21] <roycroft> sure
[23:15:29] <tjb1> lol
[23:15:35] <tjb1> The documentation doesnt say
[23:15:51] <roycroft> but if you want to use it, be sure you get the tip polarity correct - it doesn't appear to be marked
[23:16:24] <roycroft> and if it doesn't have a diode at the power inlet you could easily release the magic smoke
[23:17:38] <tjb1> Ah yes
[23:17:44] <tjb1> Ill just bottle it up and stuff it back in
[23:18:16] <roycroft> it won't work without the magic smoke
[23:19:10] <uw> hi roycroft again, have you milled pcbs before? Any recommendations for bits to use?
[23:19:29] <roycroft> no, i have not
[23:20:00] <roycroft> later this summer i shall have done so, and i may have a recommendation at that point
[23:20:22] <tjb1> Not a word about polarity in the manual either...
[23:20:33] <uw> ok just figured id ask
[23:21:08] <uw> tjb1, if you are one to randomly guess at a potential loss of the monitor, i would guess the center is +
[23:21:09] <roycroft> i would be very careful with it
[23:21:25] <tjb1> Ill probably just use the other plug
[23:21:32] <tjb1> once I figure out what that end is called
[23:21:33] <roycroft> i'd guess the tip is -
[23:21:40] <roycroft> either uw or i are correct
[23:21:46] <tjb1> lol really now...
[23:21:47] <uw> that maybe the better choice
[23:21:58] <tjb1> The standard plug the center pin would be ground correct
[23:22:11] <uw> unless that port is AC (which i have seen before like my NES ;)
[23:22:14] <roycroft> there is no "standard' tip polarity
[23:22:26] <tjb1> I meant the normal plug on the left
[23:22:29] <roycroft> oh
[23:22:31] <tjb1> not the dc adapter one
[23:22:44] <roycroft> the nema recepticle is ac
[23:22:47] <roycroft> so there is no negative
[23:23:04] <tjb1> ground...
[23:23:20] <roycroft> the center pin would be ground
[23:23:37] <tjb1> so maybe I could probe the center and get the ground on the dc
[23:24:14] <uw> they might not be the same ground
[23:24:19] <uw> but could be
[23:24:47] <tjb1> or…http://www.ebay.com/itm/Power-Cord-for-APPLE-iMac-Flat-Panel-922-6676-922-5035-/150544973086?pt=Laptop_Adapters_Chargers&hash=item230d2dfd1e#ht_884wt_1413 boom
[23:25:29] <uw> i always like this approach; guess one and if its wrong, that electronic appliance wasn't worth of you usage anyway
[23:25:31] <roycroft> you don't want a clover plug for that
[23:25:58] <roycroft> if it were me, i'd open the thing up and trace the power connector to see if the tip is + or -
[23:26:04] <roycroft> it shouldn't be hard to tell
[23:26:10] <tjb1> Why not a clover plug?
[23:26:19] <roycroft> because that's not the connector on that display
[23:26:31] <tjb1> its not? http://d3d71ba2asa5oz.cloudfront.net/43000231/images/et1515l%20(2).jpg
[23:26:49] <roycroft> oh, sorry
[23:26:55] <tjb1> :)
[23:26:58] <roycroft> i guess i've been looking at too many display pictures tonight
[23:27:09] <tjb1> hope I can win this one
[23:27:15] <tjb1> damn auctions :/
[23:27:33] <tjb1> and this monitor works with linux
[23:29:33] <tjb1> Found em.
[23:30:14] <uw> a linux working monitor? whoa hold on to that one!
[23:30:56] <roycroft> most touch screens with the elo interface work with ubuntu
[23:31:00] <tjb1> They have drivers for linux!
[23:31:03] <tjb1> wooooo
[23:31:18] <tjb1> Heh awesome, I will be driving to work when this ends
[23:31:24] <roycroft> if you install linuxcnc from the livecd the elo driver is already there
[23:31:41] <roycroft> you just plug it in and calibrate it
[23:31:56] <tjb1> Someone already outbid me
[23:32:01] <tjb1> I bet it was one of you
[23:32:28] <uw> >.>
[23:32:59] <tjb1> First item this person has bid on and they have bid on it 8 times...
[23:33:22] <tjb1> well that killed that, now its about the same price as a panel mount
[23:33:37] <roycroft> i already have four touchscreen displays
[23:33:55] <roycroft> i don't need another at the moment - i'll leave it for you
[23:34:13] <tjb1> Well in $4 im just gonna hit buy it now on the panel mount one...
[23:34:18] <roycroft> there is always a good supply of them on ebay though
[23:34:21] <uw> i also promise not to bid on the things you are bidding on
[23:34:22] <roycroft> you'll get one for sure
[23:35:10] <tjb1> I dont bid on things :)
[23:35:16] <tjb1> I purposely look for buy it now items
[23:39:02] <roycroft> i do whatever makes sense at the moment
[23:39:14] <tjb1> well ebay seems to have been taken over by china...
[23:39:34] <roycroft> i'm usually not in a big hurry to get things
[23:39:39] <tjb1> I hate looking for a car part
[23:39:47] <tjb1> Especially headlight related
[23:40:06] <tjb1> That will drive anyone mad, I dont care who you are
[23:40:29] <roycroft> i'd rather take my time and get a good value than make an impetuous decision
[23:40:45] <roycroft> i found that 4u rack mount enclosure a week ago, and bookmarked it
[23:41:07] <roycroft> just today i finally purchased it, having spent the past week looking at other options
[23:43:46] <tjb1> I like the bezel on the monitor that requires a power supply better than the other
[23:43:48] <tjb1> :/
[23:44:04] <tjb1> Can those be wired into a normal plug?
[23:44:29] <roycroft> it's likely 12vdc
[23:44:40] <roycroft> meant to take power from the main logic board of the computer
[23:45:31] <tjb1> Input (line) voltage: 100-240 VAC, 50-60 Hz
[23:45:31] <tjb1> Power consumption 30 W max.
[23:45:37] <tjb1> He has the description wrong then
[23:57:25] <tjb1> Goodnight
