[00:12:06] <jts> Hi, I am trying to run glade but I get a series of errors like the following:
[00:12:09] <jts> (glade:1894): GladeUI-WARNING **: No icon named 'widget-gtk-sizegroup' was found for object class 'GtkSizeGroup'.
[00:12:20] <jts> Does anyone know what might cause that?
[00:13:42] <psha[work]> errors or warnings?
[00:14:40] <jts> Sorry, I guess the may be warnings
[00:14:55] <jts> This is the first time I have ever tried to run glade
[00:15:00] <psha[work]> probably you've created that .ui file on more recent version of glade/gtk and using widget not available in older one
[00:15:04] <psha[work]> but that's only guess
[00:15:39] <jts> The app comes up but I am not finding the EMC specific widjets that the docs refer to
[00:16:21] <psha[work]> are you opening it with glade or running it with gladevcp?
[00:16:23] <jts> I get the same messages if I enter just glade without a ui
[00:16:37] <jts> I type glade in a terminal
[00:17:25] <psha[work]> do you have 2.5 installed?
[00:18:54] <jts> AXIS 2.4.6
[00:20:03] <psha[work]> gladevcp is available since 2.5
[00:20:24] <jts> OH OK no wonder
[00:20:36] <jts> Thanks
[01:33:57] <sirhoax> ..
[02:15:19] <pingufan> Hello, is this the former emc2 irc?
[02:17:54] <pingufan> I have a question on AXIS. There is a button [M1 ||] which I never used. What I want is to pause the CNC program at a specific point because I must then change the fixating of the workpiece. I inserted M1 into my program. Must the button be clicked or unclicked to activate M1 pausing?
[02:18:37] <pingufan> A little text pops up when I move the cursor over it, but I cannot read it. Too small.
[02:35:43] <|n0b0dy|> try it a simple jog program... g0 x0y0... m1 ... g0 x10y10 ... but the gcodes
[02:37:01] <pingufan> Thanks for your answer. I cannot try, as the program is already milling/runnung. I ~ 1 hour the M1 command will be reached, then emc2 MUST pause.
[02:37:31] <pingufan> For that: Must the icon-button in the AXIS interface be clicked (appear pressed) or not?
[02:38:00] <pingufan> I cannot read the appearing thext when the mouse is moved over the button. too small.
[02:38:23] <|n0b0dy|> oic.. if you click it now... while its running... it will pause it
[02:39:07] <|n0b0dy|> then later and your ready... one of the buttson will step line by line... and then press play to resume
[02:39:18] <|n0b0dy|> i think if you unpause it will start running again
[02:39:24] <|n0b0dy|> but it's been a while
[02:39:37] <|n0b0dy|> make note of the gcode line too case you need to go back :D
[02:43:56] <pingufan> Thank you. The worst thing would be that the mill continues and I could not change the fixature of the workpiece. You can imagine what would happen...
[04:32:04] <skunkworks_> finally gave up and installed the closed source ati video drivers for this laptop.. See how long that works :) but atleast now the fan isn't running full blast
[04:35:20] <skunkworks_> all the time
[05:01:17] <skunkworks_> heh - http://www.ebay.com/itm/Bryant-Grinder-CNC-PCB-Mesa-Elec-6M20-Circuit-Board-/390111208735?pt=LH_DefaultDomain_0&hash=item5ad470a51f
[05:05:24] <archivist> thar be gold in them hills
[08:35:00] <pcw_home> skunkworks: that's one of our first products... ISA 256K battery backed RAM or 512K EEPROM SSD (or some of both)
[08:36:17] <JT-mobile> pcw_home 7i77 manual operation field output characteristics says field power input (on TB1).
[08:37:17] <JT-mobile> should be TB2
[08:37:28] <pcw_home> OK thats wrong (I think TB1 is local 5V)
[08:37:39] <JT-mobile> yes
[08:37:55] <pcw_home> Thanks I will fix when I get in
[08:38:39] <pcw_home> putting 24V on TB1 would be bad
[08:40:26] <skunkworks_> pcw_home: neat! circa?
[08:40:52] <pcw_home> 1985/86
[08:41:52] * skunkworks_ was in middle school...
[08:41:55] <skunkworks_> ;)
[08:43:10] <pcw_home> Thats right, make me feel older :-)
[08:43:39] <skunkworks_> heh
[08:44:23] <skunkworks_> I was playing with a TI99/4A
[08:45:58] <archivist> seeing ones products years later out in the wild is amusing, I saw an amplifier(one off) we made for a musician in a shop display for sale
[08:46:29] <JT-mobile> Peter, btw nice manuals for the 7i77 and 7i76
[08:52:58] <jdhNC> http://i.imgur.com/d8fM5.jpg
[08:53:39] <skunkworks_> jdhNC: priceless ;)
[08:55:35] <JT-mobile> I hate sitting in waiting rooms!
[08:56:17] <skunkworks_> what did people do before mobile Internet! :)
[08:56:29] <skunkworks_> JT-mobile: nothing bad I hope..
[08:56:49] <JT-mobile> read national geographic I guess
[08:57:26] <JT-mobile> wife getting a disk repaired
[08:58:07] <JT-mobile> micro surgery out patient so should be home tonight
[08:59:10] <skunkworks_> ouch!
[09:00:36] <JT-mobile> next 7 to 10 days will be a bit of a pia but worth it
[09:01:47] <skunkworks_> I bet - have her take it easy - wait on her hand and foot! :)
[09:02:22] <JT-mobile> yep that is the plan
[09:03:15] <JT-mobile> be back later
[09:04:55] <skunkworks_> Good luck!
[09:58:56] <Gromits> I have a glade spinbutton. I am trying to set the increment that it increases/decreases when I click an arrow but no matter what i set I get 1.0 increments. Any ideas?
[10:02:25] <archivist> only you can see your code
[10:06:35] <skunkworks_> JT-mobile: How goes it?
[10:07:02] <JT-mobile> all is well surgery is done
[10:07:46] <skunkworks_> Great!
[10:08:26] <JT-mobile> pcw_home do you need to connect field power to all 4 pins or any one on the 7i77?
[10:08:40] <JT-mobile> on TB2
[10:09:41] <JT-mobile> yes it is great she can only lift a remote or a bell for the next few days :)
[10:10:38] <JT-mobile> can you tell what I brought to read?
[10:14:06] <skunkworks_> heh - work work work ;)
[10:14:24] <JT-mobile> fun fun fun
[10:14:54] <JT-mobile> my phone doesn't have a heh key
[10:20:57] <pcw_home> One is enough
[10:22:10] <JT-mobile> ok thanks
[10:27:29] <JT-mobile> if you have a 1000 line encoder what is the maximum rpm at 2MHz?
[10:29:02] <jdhNC> 500?
[10:29:22] <jdhNC> I don't suppose this is multiple choice.
[10:30:41] <Connor> Kinda depends on the encoder.. Is it quadrature encoder with both A & B being triggered in rise/fall ? I.E. 4 counts per line.
[10:30:57] <JT-mobile> yes
[10:31:07] <Connor> so, 4000 ticks per revolution.
[10:31:17] <JT-mobile> yep
[10:31:37] <jdhNC> 1000 lines at 500rpm is 2mhz
[10:32:22] <Jymmm> JT-mobile: FWIW Most surgical centers now have wifi, so you can bring a laptop and watch netflix or dvd or whatever.
[10:32:56] <awallin> jdhNC: are you sure about that 500rpm ? :|
[10:33:17] <JT-mobile> I was working on the laptop earlier but the wifi is borked on it
[10:33:19] <Connor> 500RPS
[10:33:29] <Jymmm> JT-mobile: DOH
[10:33:48] <Connor> 1 Mhz is 1 million Cycles a second.
[10:33:56] <JT-mobile> that makes a big difference
[10:34:15] <Connor> Need to know how many cycles it takes to read a tick.
[10:34:18] <awallin> 500rps is better. at 1000lines/rev in 4x mode I can agree that it gives 2MHz. 500rps is 30krpm.
[10:34:28] <Jymmm> JT-mobile: She in constant pain?
[10:34:44] <JT-mobile> not at the moment
[10:35:10] <Jymmm> JT-mobile: Well, I mean has she been using/taking Hydrocodone or the like?
[10:35:12] <jdhNC> heh, give or take a factor of 60.
[10:35:40] <pcw_home> Back/neck problems are just no fun at all
[10:35:58] <Jymmm> JT-mobile: WB
[10:36:09] <JT-mobile> jymmm no
[10:36:14] <Connor> JT-mobile: what's this for ?
[10:36:22] <Jymmm> JT-mobile: Oh, ok.
[10:36:50] <JT-mobile> my BP spindle max 3600 RPM
[10:36:53] <jdhNC> normally, I like my job, but at the moment I'm having to write vb.net code.
[10:37:05] <Jymmm> jdhNC: HA HA
[10:38:04] <Connor> You just trying to do RPM or you syncing it up for something ?
[10:38:44] <jdhNC> in 30 mins, I'm driving to .fl.us for 4 days of diving
[10:39:09] <JT-mobile> for rigid tapping when I get the 5i25/7i77 in
[10:40:27] <Connor> okay, so syncing the RPM to the feed rate.
[10:41:07] <Jymmm> JT-mobile: *IF* she starts getting pain/numbness in limbs/back look at Sciatica, it seems to be commonplace after hip/knee replacement surgery and the like... http://en.wikipedia.org/wiki/Sciatica
[10:41:18] <JT-mobile> yep
[10:41:59] <JT-mobile> jymmm this was a herniated disk.
[10:42:10] <Jymmm> JT-mobile: know which one?
[10:42:22] <JT-mobile> L5
[10:43:16] <Jymmm> JT-mobile: Yeah, that's the area the Sciatica can complicate. Be aware of Pain Patch (Lidoderm) as well.
[10:43:50] <JT-mobile> ok
[10:43:53] <Jymmm> L3, L4, L5
[10:47:08] <Gromits> I have a spinbutton called hal_spinbutton3. In the glade panel for Signals for it, I have GtkWidget -> realize set to on_hal_spinbutton3_realize. I have a python script as shown here: http://pastebin.com/CyLAkMXx I have this config line in .ini: GLADEVCP= -u ../a2gantry-triv-beta-glade/tom-test.py ../a2gantry-triv-beta-glade/gantry-panel.ui but this value does not get set in the box when...
[10:47:09] <Gromits> ...Axis comes up.
[10:48:34] <JT-mobile> bbl
[10:52:35] <mhaberler> what is the point in *setting* a spinbutton? this is an input widget
[10:52:51] <mhaberler> use the value in the adjustment
[10:52:58] <Gromits> The point is that when Axis comes up I want a default value
[10:53:13] <Gromits> I tried setting the value in the adjustment, but nothing happens
[10:53:34] <Gromits> I also hand edited the file to set the value in the adjustment to no avail
[10:53:54] <mhaberler> value last, you mean? that old bug in gladexml?
[10:53:57] <Gromits> then I saw your post in the forum a while back hence, trying the on_realize thing
[10:54:20] <Gromits> value last?
[10:54:39] <mhaberler> the order of attributes is wrong as it comes out of glade
[10:54:56] <mhaberler> on spinbutton, I think; but I guess this is unrelated
[10:55:12] <Gromits> so do I need to re-order them or something?
[10:55:29] <mhaberler> let me see.. hold on.
[10:58:21] <mhaberler> you might have to emit a value-changed signal. see here: http://python.6.n6.nabble.com/Setting-value-of-gtk-SpinButton-without-triggering-the-quot-value-changed-quot-event-td1946512.html
[11:03:28] <mhaberler> you might want to ask psha over at linuxcnc-devel
[11:04:35] <mhaberler> at least a known issue: http://bytes.com/topic/python/answers/474382-gtk-spinbutton-set_value
[11:05:50] <mhaberler> ah: call widget.update() after widget.set_value(xxx) - see http://www.c-plusplus.de/forum/180160 (German)
[11:07:14] <mhaberler> update policy might help, too: http://www.pygtk.org/pygtk2tutorial/sec-SpinButtons.html
[11:07:53] <Gromits> I have the policy set to if valid already...
[11:08:20] <mhaberler> does widget.update() help?
[11:08:32] <Gromits> i put widget.update() in the .py file but it didn't work....
[11:08:57] <Gromits> is this syntax correct...?
[11:09:04] <Gromits> def on_hal_spinbutton3_realize(self,widget):
[11:09:06] <Gromits> widget.set_value(0.150)
[11:09:07] <Gromits> widget.update()
[11:09:34] <mhaberler> same indentation as widget.setv_value, otther than thatyes
[11:10:25] <mhaberler> that was the Gtk bug: http://osdir.com/ml/gtk-app-devel-list/2010-04/msg00129.html
[11:11:26] <Gromits> hmm, I fixed indentation (used tabs instead of spaces), but no help...
[11:14:27] <Gromits> changing the order (according to that last link), worked! What a pia though, having to change the order after running glade :-(
[11:14:50] <Gromits> of course i also have to hand edit to add blink values in by hand....
[11:15:23] <Gromits> thanks mhaberler!
[11:16:05] <mhaberler> you'd be better of if you can force it in the handler, thus you wont have to fix it after editing the gui
[11:16:19] <Gromits> How can I do that?
[11:16:42] <mhaberler> please pastebin code
[11:16:54] <Gromits> which code, .ui?
[11:20:14] <mhaberler> py
[11:21:26] <Gromits> http://pastebin.com/ptx8MMEN is gantry-panel.ui. if you look at adjustment3 you will see where I moved value. http://pastebin.com/qdqb8a4R is tom-test.py.
[11:22:22] <Gromits> by the way, I ultimately want to try your suggestion about using on_destroy to save the value and reload. Just working my way up to that :-)
[11:24:22] <mhaberler> yes, thats very convenient
[11:25:02] <mhaberler> looks ok - re update: what doesnt work: screen update, hal pin update, both, neither?
[11:26:24] <Gromits> Well, I haven't even gotten to see if hal pin actually get value, I was just trying to get it to appear on the screen in Axis. So, for now, just screen update....
[11:27:03] <mhaberler> that would be interesting (and important, I assume)
[11:27:13] <Gromits> yes :-)
[11:27:26] <mhaberler> halshow is your friend
[11:27:52] <Gromits> will look for pin with re-ordering hack....
[11:29:43] <Gromits> yes,as you probably suspected hal pin value is 0 even though Axis shows 0.150...
[11:32:27] <mhaberler> Axis? you mean the gladevcp panel?
[11:32:31] <Gromits> I have to click on the spin arrow to get it to change the hal value
[11:34:49] <mhaberler> in the handler, add widget.hal_update() after the update()
[11:34:51] <mhaberler> not sure
[11:35:18] <TRW_Ags_Mx> Hi, some body has the manual for a SLO-SYN 440-TH125 stepper driver from Superior Electric?, i google it without luck and the people of Dana Motion said i to old for support
[11:35:40] <mhaberler> alternatively, try widget.emit("value-changed") instead of the update calls
[11:37:09] <mhaberler> reading lib/python/gladevcp/hal_widgets.py might help a bit; and manual changes are welcome;)
[11:39:05] <JT-mobile> is that a hint?
[11:40:03] <Gromits> looks like it's time to read the manual, neither of those worked. thanks though...
[11:40:17] <mrsun_> hmm, tumbling something that is milled without a trammed spindle feels like futile
[11:40:39] <mrsun_> looks like he got deep grooves and tries to tumble them out =)
[11:41:02] <mrsun_> http://www.youtube.com/watch?v=MA36rSb1SlE&feature=related dont know how good you can get stuff by tumbling directly from a mill tho ? :)
[11:57:19] <Jymmm> Maybe I should send in this photo http://i37.tinypic.com/nvqukn.jpg to them http://sfbay.craigslist.org/sby/ofc/2836511975.html
[12:05:23] <mhaberler> Gromits: what version are you using?
[12:05:54] <mhaberler> we recently fixed something around spinbutton
[12:06:49] <mhaberler> http://git.linuxcnc.org/gitweb?p=emc2.git;a=blobdiff;f=lib/python/gladevcp/hal_widgets.py;h=33430b2e88bd609ab9198df627dd9a29f40edc35;hp=184c1cfbac5d757b2d0bcf244578f4286919d919;hb=d1b6e4174a2249e75129712645efaa214f83c6ef;hpb=d4ff1bf165a3f206336ce3c56299c660a17b281c
[12:23:41] <JT-mobile> is there a tab key on an eye phone?
[12:25:40] <joe9> Any suggestions for a good milling machine, please? I have one from harbor freight, but I want to upgrade to a better one. one with metric scale?
[12:26:25] <syyl> better ones?
[12:26:27] <isssy> good miling - new miling
[12:26:30] <syyl> there ary many
[12:26:34] <syyl> *are
[12:27:26] <syyl> ranging between "can be lifted by a single person" and "needs its own basement to be placed on"
[12:29:34] <syyl> so, someone could advice you anything between a aciera f1 and a waldrich coburg gantry mill...
[12:29:59] <Connor> joe9: Are you going to CNC it ?
[12:30:21] <JT-mobile> a grizz would be better than a harbor fright by a little
[12:30:23] <joe9> i do not yet. but, would love to do it in the future.
[12:30:40] <joe9> something that can handle 8cm x 8cm or 10cm x 10cm sizes
[12:30:59] <joe9> connor: I am not sure about cnc'ing it. though, would love to do it at some point.
[12:31:07] <Connor> joe9: Grizzly G0704 is a nice machine.. Bigger than the Mini Mills. It's not metric. They're BF20's which might be metric though
[12:31:20] <joe9> Connor: thanks. will check it out.
[12:35:37] <Gromits> mhberler: the fix you posted solved our problems!!!
[12:36:13] <Gromits> don't even need the update(), it just updates...
[12:37:15] <mhaberler> I lost track what the fix was..
[12:37:33] <Gromits> that last link you posted...
[12:37:50] <mhaberler> oh, you mean the linuxcnc version
[12:38:12] <Gromits> yes/
[12:38:39] <Gromits> by the way, is that thing you posted in the latest 2.5 build (from src)?
[12:38:50] <Gromits> If I just git pull and rebuild, I'll have it?
[12:38:57] <mhaberler> I think so, its in v2.5_branch
[12:39:17] <Gromits> ok, thanks
[12:39:50] <mhaberler> and in master too
[12:55:25] <cncjerry> hello, it's been a while since I was on here. don't know if anyone can help on this one. I am using standard G1/G2 arcs and they seem to have very slight faceting.
[12:55:42] <cncjerry> is there a way to increase the interpolation of EMC2 for Arcs?
[12:56:15] <cncjerry> I could force my CAD/CAM system to output xy moves but the files would get huge.
[12:57:09] <cncjerry> before you ask, I believe my servo and pully setup give me 1/12000 resolution.
[13:00:26] <syyl_ws> is there g64 active?
[13:02:11] <cncjerry> refresh me on G64.
[13:03:07] <syyl_ws> http://www.linuxcnc.org/docview/html/gcode.html
[13:03:19] <cncjerry> isn't that something like exact stop? and wouldn't that stop at the end of the arc?
[13:04:10] <cncjerry> the faceting I am seeing is around the arc. the arcs reverse and are tangent. I don't see anything unusual at that point where the come together except very slight backlash.
[13:10:32] <archivist> cncjerry, you have backlash?
[13:11:59] <cncjerry> slight backlash, like around .001
[13:14:59] <cncjerry> also, the arc in question is a G1. I don't see it on a G2, go figure.
[13:15:56] <archivist> ah see source of the arc :)
[13:16:56] <cncjerry> I meant G2 vs G3
[13:17:57] <cncjerry> so it is on G2 but not G3. The g2 arc radius is .5", the following arc is roughly .1875
[13:18:50] <cncjerry> I'll play with the G64 to see if it helps. I was mostly wondering if there was an overall arc interpolation param that might be causing the problem.
[13:28:49] <cradek> g2 and g3 arcs are not ever split up into lines in linuxcnc
[13:31:22] <cradek> also this will have nothing to do with g64
[13:32:05] <cradek> can you show us a picture of what you are seeing?
[13:32:33] * archivist stops asking for a p...
[13:37:54] <cradek> arcs of different radii will have different apparent feeds on the outside vs inside, and if the arc radius is near the cutter radius this effect can be extreme
[13:38:41] <cradek> so my wild-ass guess is you are seeing machining marks and misinterpreting them as linear interpolation
[13:39:25] <cradek> replace 'arcs of different radii' with 'arcs'
[13:39:30] <cradek> that was probably clear as mud
[13:42:20] <archivist> I agree about machining artifacts (resonance, aliasing of cutter rpm with resolution of the drive/machine stiction/machinestiffness) looking like a software error
[13:42:46] <archivist> also as clear as mud
[13:43:54] <cradek> .1875 is a pretty tiny arc, so I'm assuming a tiny flexible tool too. I think there's likely to be an unexpected apparent feed on the side you want to keep and you might be able to fix it by simply adjusting the feed for that arc
[13:44:32] <cradek> many cam packages adjust arc feeds (using their knowledge of which side you want to keep, which is not part of gcode) for this reason
[13:45:44] <archivist> I would expect to see tool bending with tiny tools, that also effects finish
[13:46:20] <cradek> too bad he's disappeared
[13:48:18] <archivist> and another when he wakes up is climb v conventional milling giving different finish
[13:48:46] <cradek> you bet
[14:17:33] <Jymmm> Has anyone used a soda blaster?
[14:21:48] <jdhNC> get one and try it on my boat.
[14:22:29] <Jymmm> heh
[14:22:46] <Loetmichel> soda blaster?
[14:22:49] <Jymmm> jdhNC: Sure, insert credit card here --> [ ]
[14:22:56] <Jymmm> Loetmichel: google it
[14:23:16] <Loetmichel> ah!
[14:23:22] <Jymmm> like sand blasting but with baking soda
[14:23:23] <Loetmichel> c02 snow
[14:23:28] <jdhNC> Lotz oflayers of bottom paint
[14:23:40] <Jymmm> Loetmichel: baking soda, not co2
[14:23:55] <Loetmichel> instead of sand?
[14:23:59] <Jymmm> yeah
[14:24:10] <Loetmichel> and that does something?
[14:24:13] <Loetmichel> interesting
[14:24:18] <Jymmm> yeeeeeeeees
[14:25:14] * Loetmichel would have guessed it would be to soft to do any work
[14:25:27] <Jymmm> jdhNC: I'm trying to come up with a way to reuse reclaimed wood (decking.fencing,etc) to basically "clean up" any paint and muck quickly and easilt
[14:25:42] <Jymmm> Loetmichel: there are some abrasives in it
[14:26:22] <Loetmichel> and does no harm to steel i suppose?
[14:26:27] <Loetmichel> nice idea
[14:26:34] <Jymmm> nfc, never used one thus why I asked.
[14:27:09] <Loetmichel> i've seen a co2 snow blaster working lately. also a ingenious idea to remove dirt/paint without leaving ANY residue ;-)
[14:27:48] <Jymmm> with co2? pics? link?
[14:28:01] <jdhNC> it doesmt hurt gelcoat
[14:28:13] <syyl_ws> go for dry ice blasting, Jymmm

[15:01:21] <Jymmm> ve7it: cool btw =)
[15:02:01] <ve7it> side scan sonar for mapping the fishing grounds around here....
[15:02:25] <Jymmm> ve7it: Ah, fishing a la technology =)
[15:02:38] <Jymmm> ve7it: You know a m80 is much faster
[15:02:40] <ve7it> I'm too cheap to buy one, so am spending all winter building one.
[15:03:15] <ve7it> yea... I dont have any CIL lures at the moment
[15:03:16] <Jymmm> ve7it: light, toss, scoop up the fish
[15:03:46] <Jymmm> ve7it: what is a DSpic ?
[15:04:03] <ve7it> a fast little PIC microcontroller
[15:04:27] <Jymmm> oh, I thught the DS was Digital Signal Processing in a PIC form
[15:05:42] <ve7it> it does have DSP instructions, but it is also a very nice integrated system... basically a 16 bit computer on a chip with cool i/o devices, ram, eeprom built in
[15:05:51] <ve7it> programmable in C
[15:08:31] <Jymmm> ah, cool
[15:09:06] <ve7it> Jymmm, http://www.flickr.com/photos/64111811@N00/6843033691/in/photostream circuit diagram... not much extra stuff required, oscillator, reset logic and power bypass caps
[15:10:52] <jdhNC> my lowrance HDS has a SS option but Im cheap
[15:28:24] <Jymmm> Some of these are pretty funny... http://www.youtube.com/watch?v=VdR_wCZJYMM&feature=related
[15:34:26] <cncjerry> cradek et al. I'm back. had to run out. I cant take an effective picture because the facets are so light. They look exactly like what you would get if instead of using g2/g3 you set your cam program to do successive G1 moves with a high interpolation setting.
[15:35:16] <cncjerry> by interpolation, as in catia, I can say something like .01 for maching tolerance and it will leave big facets vs .0001 and you get small (without circular interpolation).
[15:36:05] <archivist> cncjerry, ive seen lines like that which are resonance/tool vibration problems
[15:36:31] <cncjerry> in this case, the outside radius of the part has very, very light facets. also, I am running a finish pass with a reverse spring pass. so it does climb once and then returns.
[15:37:04] <cncjerry> I thought resonance and I've seen that but they are more like a banboo fence kind of look.
[15:38:07] <cncjerry> another wierd thing is that the facets are symetrical on opposite sides of the peak where it moves from x+ to x- if you follow me.
[15:38:07] <archivist> depends on spindle speed and tool helix there are magic speeds where it can be a line
[15:38:56] <archivist> that can be backlash/machine spring/stiction
[15:39:04] <cncjerry> these facets are about an 1/8" long. they arent true facets, more like non-smooth small arcs.
[15:39:45] <cncjerry> I'm not worried about them. by the time the tumbler is done with them nobody will know.
[15:39:46] <archivist> is the tool grabbing and taking a bite
[15:40:43] <cncjerry> it is brass so it could be but the facets are too regular. using flood coolant, about 3000rpm and 5ipm for finish.
[15:42:05] <cncjerry> now I am wondering if maybe something is stuck on the timing belt. so that when it comes around or hits a tooth it joggles the machine.
[15:42:13] <cncjerry> on one of the axis.
[15:42:35] <cncjerry> and btw, I remember seeing the same on aluminum.
[15:42:54] <archivist> possible, you can measure that and check
[15:43:14] <cncjerry> I am using the old 2.3 version of emc since I had modified AXIS so much
[15:43:27] <cradek> did you understand what I said about apparent feed on small arcs?
[15:43:28] <cncjerry> I am going to make sure it is in constant velocity mode
[15:43:56] <cncjerry> yes, my software allows me to set slowdown rates for different corners as well as arc size, etc
[15:44:15] <cncjerry> under the Highspeed milling tab in Catia.
[15:45:15] <cncjerry> I had reset my quill preload recently and that made the finish almost perfect now. I wonder if I would see the facets if the finish wasn't so bright
[15:48:32] <cncjerry> I got a picture, where can I post it?
[15:49:53] <archivist> one of the image bins
[15:51:34] <ve7it> jdhNC, yea... I would like an HDS 8 with the ss option, but that comes in at about $3000 canuck dollars with taxes.

[16:12:20] <mhaberler> yes
[16:12:31] <syyl> no complicated fixturing needed :)
[16:12:39] <syyl> only a vice
[16:12:39] <Gromits> I have a config working that creates an .ini file and saves a value on destroy.
[16:13:25] <mhaberler> good
[16:13:44] <mhaberler> you seem to be #2 (I was #1)
[16:13:44] <Gromits> I then changed it to put the save state function on window1 and it doesn't ever call it...
[16:13:50] <Gromits> def on_window1_destroy(self,obj,data=None):

[16:17:31] <Jymmm> lol
[16:17:36] <Jymmm> ok, fair enough =)

[16:18:35] <Loetmichel> a 170cm height dome tent costs about 200 eur
[16:18:36] <Jymmm> so that'ssssss what, 49 Euro?
[16:18:47] <Loetmichel> more at 60
[16:18:51] <Jymmm> k

[16:23:11] <Gromits> Error is: http://pastebin.com/tUxtQfjM, py file is: http://pastebin.com/juusPaLs
[16:24:41] <tom3p> Loetmichel, is there another part where the struts joint together? ( maybe a plate, or maybe the struts join to struts )
[16:24:56] <Loetmichel> tom3p: last pic
[16:25:11] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12791
[16:25:28] <Loetmichel> thats the reason why the struts are fattened at the end
[16:25:28] <Loetmichel> flattened
[16:25:30] <mhaberler> style: you dont need gobs of realize and destroy handlers - one is ok, and set all widget values there
[16:25:31] <tom3p> http://www.cyrom.org/palbum/main.php?g2_itemId=12791 ?
[16:25:36] <Loetmichel> yes
[16:26:07] <Gromits> yeah, we were about to consolidate that. we realized that too after a while...
[16:26:07] <tom3p> Loetmichel, uh, theres a bolt, do many struts connect to the bolt?
[16:26:25] <Loetmichel> hole in the flat end, lockscrew throuch, stack all mating ends, washer and nut-> done
[16:26:30] <Loetmichel> 5 or 6
[16:26:33] <Loetmichel> tops
[16:27:08] <tom3p> ok, right 5/6, if you use the material used to shrin wrap boats for winter, you get a tensegrity instead of simple geodesic
[16:27:14] <Loetmichel> and taht is also the reason fopr the bend in the flat end
[16:27:14] <Loetmichel> for
[16:27:43] <tom3p> the skin tenses the frame making it strong
[16:27:45] <Loetmichel> tom3p: you are bringing ideas forth...
[16:28:05] <tom3p> fenn worked on these ideas too
[16:28:55] <Loetmichel> i have som spools black shrink wrap in the company .... no need for cutting and glueing the gewebeplane... just running arount the frame with a spool of shrinkwrap ;-)
[16:29:15] <Loetmichel> around
[16:29:23] <mhaberler> I dont understand why you restore all widgets - save_state and restore state should take care of that; see the complex example
[16:29:25] <tom3p> i like the tool that flattens the end, i suspect theres a hot air gun somewhere ( haha dont get dizzy)
[16:30:02] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12779
[16:30:10] <Loetmichel> there, the green one ;-)
[16:30:10] <Gromits> we just found the complex example and were trying to consolidate everything. that is when we created the window1 destroy but then found this problem
[16:30:30] <mhaberler> ok. Start over with complex.py
[16:30:57] <tom3p> Loetmichel, :) thx best let the python discussion go now
[16:31:03] <Loetmichel> sorry
[16:31:27] <mhaberler> the HAL widgets *are* restored provied you state so in the ini descriptor; either all or selectively. It's all there and documented..
[16:32:08] <Gromits> ok, let me clean it up and see if we still have this issue...
[16:32:37] <mhaberler> good
[16:52:28] <cncjerry> cradek, if you are still around, here is a picture http://dl.dropbox.com/u/61309428/photo-2.jpg
[16:52:48] <cncjerry> this is the faceted outside edge, don't know if you can tell.
[16:53:07] <syyl> from that picture
[16:53:12] <syyl> i cant tell anything ;)
[16:53:34] <elmo401> lol. wrong view :-P
[16:54:52] <cncjerry> the problem I am having is that I have very light facets on outside arc's opposed to inside. The problem is in G2 vs G3, I think.
[16:57:11] <sirhoax> heynow
[16:57:28] <sirhoax> moment of truth.

[16:59:40] <syyl> magic blue smoke?
[16:59:42] <Jymmm> No, I've stolen them beofre =)
[16:59:56] <sirhoax> it worked on the livecd
[16:59:56] <sirhoax> heh.
[17:00:11] <sirhoax> no smoke plez!

[17:00:36] <Jymmm> sirhoax: got Skewer?
[17:00:36] <skunkworks_> cncjerry: I had something recently on one part I was doing.. I ended up finding out the cutter dullness/ feed / rpm was causing it. (I only saw it on that one part - nothing else)

[17:04:08] <syyl> jep
[17:04:15] <syyl> in the endcaps
[17:04:30] <Jymmm> syyl: Be sure to be selective with the diffuser material
[17:04:44] <Jymmm> syyl: Sometimes the simplest of things work best.
[17:04:57] <Jymmm> syyl: plain old copy paper as example.
[17:05:00] <syyl> ah
[17:05:04] <syyl> good idea
[17:05:09] <Jymmm> syyl: wax paper, butcher paper, etc.
[17:05:15] <syyl> i thought of some opaque plastic
[17:05:57] <syyl> like acetal
[17:05:57] <Jymmm> syyl: velium is too expensive and doesn't difuse the light all that well
[17:05:57] <syyl> i will try it, thanks for the advice
[17:06:01] <Gromits> Any idea what this error means?
[17:06:02] <Jymmm> syyl: just layer copy paper till you get the look you want
[17:06:04] * syyl takes a note
[17:06:05] <archivist> cncjerry, cant see really pic is too small and left hand is burnt out

[17:06:29] <Gromits> I don't have an object with this width/height, yet I get this everytime...
[17:06:58] <Jymmm> syyl: Also, cut strips of copy paper and spray glue n other paper, gives a two tine effect
[17:07:01] <Jymmm> two tone
[17:07:20] <Jymmm> syyl: crinkling paper sometmes works too
[17:07:53] <syyl> i can see that that might give a cool effect
[17:07:56] <Jymmm> syyl: Also, paper seperated by a cm or so helps big time
[17:08:08] <Jymmm> for even distribution
[17:09:00] <syyl> a cm? i thought you are a inch-guy ;)
[17:09:11] <Jymmm> syyl: save that protective film you have overthem in the photo, might give a neat effect
[17:09:43] <Jymmm> i try
[17:10:15] <syyl> ok, some good ideas, i am going to try
[17:10:18] <syyl> but now
[17:10:26] <syyl> heading for my bed :D
[17:10:31] <Jymmm> TMI
[17:11:05] <syyl> three mile island?
[17:11:08] <Gromits> I can't seem to get this right. I still get that error about window being unexpectedly destroyed... Here is .py: http://pastebin.com/FWVwciEk here is error: http://pastebin.com/XgraTEbk
[17:13:31] <cncjerry> I have another string of parts, four in a line, that use the same code. They all have light facets on the outside arc and none on the inside. I've used other cutters, etc. The facets are identical on the four parts even though they are offset by 1.5 inches. So it is in the software.
[17:13:57] <cncjerry> I cant figure it out. I am going to play with G64 and exact vs continuous.
[17:14:31] <archivist> thaat conclusion is not implied by the offset at all
[17:15:12] <cncjerry> well, I say it is in the software but who knows. since the parts are offset by 1.5 inches, you would think if there was a jam or something in the axis drive, that the results would be different, no?
[17:15:30] <archivist> if you dwell at that point you will get a mark
[17:15:38] <cncjerry> no dwell.
[17:15:54] <cncjerry> it looks like it is running very smoothly when I watch it.
[17:16:39] <archivist> if it is on the 90/180/when a direction changes and there is any spring/stiction/backlash you will get a mark
[17:17:25] <cncjerry> it could be something to do with running so slow. The mill is gear for optimal cutting at 60ipm. and I have a very slight mark at the axis change as you point out.
[17:17:49] <Gromits> need to leave, will check back in later or tomorrow...
[17:18:24] <cncjerry> I didn't mean to take a shot at emc, by software it could be anything, maybe a repeating interupt, mouse move, etc while it is cutting.
[17:19:15] <cncjerry> maybe it is taking a straight line from the two points on the arc in order to hit a certain speed under continuous cutting (G64)?
[17:21:26] <archivist> may I remind you of <cradek> g2 and g3 arcs are not ever split up into lines in linuxcnc
[17:21:27] <archivist> <cradek> also this will have nothing to do with g64
[17:24:01] <cncjerry> got it
[17:25:12] <cncjerry> the other thing is that the facet is really not a line, it is almost like the arc was offset by .0001 or less and then put back on the next facet. so the facet is a discontinuity in the arc not an arc made up of straight lines.
[17:26:43] <cncjerry> maybe I should upgrade emc? I am running on the old 2.3(?) version.
[17:27:36] <cncjerry> wasnt there a lot of changes in the drive in 2.4? I remember something about continuous cut or constant velocity being reworked or tweaked in 2.4
[17:28:41] <sirhoax> trying to fine tune this thing.
[17:28:50] <sirhoax> last time 8000 steps/in was it.
[17:29:01] <sirhoax> er. this card has the optos !!
[17:29:42] <sirhoax> anyone running the *.cn card w/optos?
[17:32:36] <sirhoax_> heh. crashed it.
[17:34:38] <sirhoax_> no smoke atleast.
[17:35:47] <sirhoax_> need to get a new controller
[17:36:15] <sirhoax_> anyone build off of the step genie?
[17:36:19] <sirhoax_> make their own.
[17:41:37] <sirhoax_> it old sounds the same, no matter how i change the config. heh.
[17:41:43] <sirhoax_> er. it all --^
[17:42:06] <sirhoax_> should hook up the cnc. see how its getting driven.
[17:42:14] <sirhoax_> to the oscilloscope.
[17:43:00] <sirhoax_> the most i can get out of this thing with the *.cn controller is 18ipm atleast from the last mach3 config that is what it said it did.
[17:43:16] <sirhoax_> think it can do the most 30VDC.
[17:43:22] <sirhoax_> only running 12VDC ATM.
[17:43:41] * sirhoax_ hears crickets.
[17:47:00] <sirhoax> cradek, are you from *.pl ?
[17:51:17] <sirhoax> lol. the most the Y can do is . time to accelerate to max speed: 0.01s distance to accelerate to max speed: 0.0015in pulse rate at max speed: 2400Hz Axis SCALE: 8000steps/in.
[17:51:27] <sirhoax> er. damn optos.
[17:53:30] <sirhoax> anywho it works.
[17:54:21] <sirhoax> weird tho that my Y has a different velocity setting than the XZ
[17:54:30] <sirhoax> by .1 in/sec
[18:29:38] <elmo401> I think cncjerry has too much backlash ;)
[18:29:44] <elmo401> but he doesn't want to admit it
[20:21:50] <minibnz> hi all just wondering if anyone here has used a SEIG X2 mill, i am thinking of buying one to complement my 3d printer, and was thinking with all my left over parts i can CNC it :) just wondering what they are like to use
[20:22:53] <minibnz> going to add a dividing head and DRO to it so i was thinking EMC might be a good choice to drive it
[20:28:57] <Gensor> who here is running mirc?
[20:31:45] <Tom_itx> me
[20:32:40] <Gensor> I cant remember how to enable it so it opens web pages when www etc shows up
[20:33:12] <Tom_itx> automatically?
[20:33:21] <Tom_itx> i've never done that
[20:33:29] <Gensor> yes... i had it working one time
[20:34:15] <Tom_itx> Irc options catcher
[20:34:19] <Tom_itx> look there
[20:35:09] <Gensor> can you send me a www.xxx etc
[20:36:07] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/Boxes/milling1.jpg
[20:39:15] <sirhoax> slowly loading here.
[20:39:31] <Tom_itx> yeah my router sucks
[20:39:31] <Tom_itx> sorry
[20:39:33] <Gensor> nice sherline
[20:39:47] <sirhoax> heh. need to downsize the image size ;-)
[20:40:01] <Gensor> can you send another link?
[20:40:04] <sirhoax> nice what are you milling wax?
[20:41:21] <Tom_itx> no a plastic box
[20:41:25] <Tom_itx> for my programmers
[20:41:50] <sirhoax> k.
[20:43:47] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/USBTiny_Mkii_index.php
[20:43:47] <Tom_itx> those
[20:43:47] <Tom_itx> don't click on that, i'm gonna reset the router
[20:43:47] <Tom_itx> gawd it's slow
[20:46:21] <minibnz> oh backlash hmmm, i have a mate that said me would help if i need it to clean it up
[20:46:24] <Tom_L> that should be alot better
[20:46:54] <minibnz> ooo <seb_kuzminsky> thanks for the warning
[20:47:32] <seb_kuzminsky> minibnz: it definitely needs cleanup and tuning and truing before you use it
[20:47:56] <Gensor> anyone know of a bridgeport interact for sale other than ebay?
[20:48:05] <seb_kuzminsky> polish the gibs, align the column, align the spindle axis with the column (google for rollie's dad's method)
[20:48:30] <seb_kuzminsky> bbl
[20:52:34] <Tom_itx> Gensor, http://www.maritool.com/Tool-Holders/c23/index.html
[20:52:39] <Tom_itx> there's your other link
[20:53:50] <Tom_itx> does that option really work?
[20:53:55] <Tom_itx> i didn't even know it was there
[20:56:12] <Gensor> works fine now
[21:02:29] <sirhoax> anyone know of a good spindle for small engraving bits?
[21:02:53] <sirhoax> using a portal cable now
[21:03:08] <jdhNC> how much do you want to spend?
[21:03:36] <sirhoax> money is the issue. was looking at wolfgangengineering's spindles.
[21:03:48] <sirhoax> guess there isn't a cheap alternative.
[21:04:15] <sirhoax> the porter cable is good for 0.06" not sure if its good any smaller.
[21:06:20] <sirhoax> for milling plexiglass is there a secret? heh.
[21:06:33] <sirhoax> because polycarbonate isn't as bad to mill.
[21:07:05] <Tom_itx> don't get it hot
[21:08:01] <sirhoax> the polycarbonate was machining alright.
[21:08:19] <sirhoax> not the plex. or it could be acrylic.
[21:08:21] <sirhoax> unless its the same.
[21:08:28] <Tom_itx> same
[21:08:38] <Tom_itx> there are a couple different kinds
[21:08:51] <sirhoax> yea polycarbonate is a better alternative. compared to plexiglass.
[21:08:55] <Tom_itx> one is more expensive than the other
[21:09:26] <Tom_itx> one is cast
[21:09:34] <Tom_itx> i forget about the other
[21:09:56] <jdhNC> there are cheapish chinese spindle+vfd combos on ebay and keling
[21:10:20] <Tom_itx> put good bearings in them and i hear they're ok
[21:10:34] <sirhoax> what about an air spindle?
[21:10:34] <Tom_itx> no personal experience there
[21:10:47] <cstop> spindles? No clue about price, but we have three of the small machines in commercial service for over ten years without a hitch http://www.visionengravers.com/products/Vision-router-engraving-accessories.html#C2
[21:12:02] <sirhoax> dentistry tool, possibly.
[21:12:16] <sirhoax> must sound nice ;-)
[21:12:24] <sirhoax> neighbors will think i'm drilling teeth.
[21:12:29] * sirhoax snickers.
[21:17:21] <hmm> Quick question: What's the difference between a profiling and a pocketing operation?
[21:17:46] <hmm> It's possible to profile the inside of a pocket but not possible to pocket the perimeter of a profile, right?
[21:17:46] <Tom_itx> pocket removes it all
[21:17:54] <Tom_itx> profile cuts the perimeter
[21:18:01] <hmm> ok
[21:18:03] <hmm> thanks
[21:18:31] <sirhoax> heh.
[21:18:36] <jdhNC> unless you just want a pocket the same width as your cutter
[21:18:57] <Tom_itx> pocket usually allows for islands etc
[21:21:05] <jdhNC> cheap spindle: http://www.cnconabudget.com/
[21:23:03] <sirhoax> need a spindle to etch circuit boards
[21:23:17] <sirhoax> think its .005" if my memory serves me correct.
[21:24:13] <sirhoax> guess that spindle may do it.
[21:26:13] <sirhoax> just like the idea of air, but again would have to run a compressor.
[21:26:24] <sirhoax> but it doesn't consume much air from what i've heard.
[21:26:30] <jdhNC> compressors suck
[21:27:51] <sirhoax> yea just adds to the mess. heh. not much space here as it is.
[21:28:15] <jdhNC> the noise is awfuj
[21:28:51] <Tom_itx> stick it in a room by itself
[21:29:04] <Tom_itx> our screw compressor was
[21:29:20] <Tom_itx> but it was like standing next to a jet
[21:29:31] <Tom_itx> well not quite that bad..
[21:30:54] <Tom_itx> i should show you how to 'etch' circuit boards :)
[21:31:27] <Tom_itx> i tried milling and didn't like it
[21:31:49] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/etching/etch_index.php
[21:31:54] <Tom_itx> that's my tank
[21:33:14] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/temp/tiny/tinyTPI2.jpg
[21:33:28] <Tom_itx> that has 3 traces under it (SOT23-6 package)
[21:33:46] <sirhoax> nicely done.
[21:33:46] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/temp/tiny/tinyboard2.jpg
[21:34:00] <Tom_itx> toner transfer
[21:34:24] <sirhoax> http://youtu.be/DT0xDY31ZX0
[21:34:45] <sirhoax> successful milling PCB .. expensive spindle.
[21:34:58] <Tom_itx> my spindle rpm isn't high enough
[21:38:40] <sirhoax> need a better controller. his machine moves much faster than mine.
[21:39:00] <sirhoax> er. frustrating w/slow speeds.
[21:39:07] <Tom_itx> yep
[21:39:23] <Tom_itx> i figured with what i have it would be easier to etch
[21:39:41] <Tom_itx> most things i'm serious about anymore i just have done
[21:40:41] <Tom_itx> although i've got enough copper to last the rest of my lifetime
[21:43:11] <sirhoax> guy doesn't even sell the spindles anymore
[21:43:15] <sirhoax> http://stores.ebay.com/Wolfgang-Engineering
[21:59:02] <sirhoax> http://www.brusselsprout.org/CNC/1P-Probe/
[22:00:41] <sirhoax> grrr. mach3 !
[22:00:47] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/probe_index.php
[22:02:42] <sirhoax> nice.
[22:07:30] <sirhoax> can't wait to finally work out all the quirks w/this cnc
[22:07:59] <sirhoax> between setting it up and coding. it has been a bumpy start trying to find the best means to get efficient using it.
[22:08:25] <sirhoax> think i may have a system. but, we'll see its constantly being revamped.
[22:09:04] <sirhoax> wanted to do the 4th axis.
[22:09:11] <sirhoax> not even sure i'll find the time.
[22:09:35] <Tom_itx> i know my time is limited
[22:09:47] <Tom_itx> i wanted to make a rotary but never seem to find time
[22:10:19] <Tom_itx> it might be different if i was doing production work

[22:10:44] <frysteev> oopos
[22:10:45] <frysteev> sorry
[22:10:55] <sirhoax> nice autojoin post.
[22:10:57] <sirhoax> ;-q
[22:11:09] <frysteev> copy paste fail
[22:11:28] <frysteev> err I ARE A BOT
[22:11:50] <frysteev> i was meaning to tease Jymmm with http://megacyclelabs.com/?p=198
[22:12:26] <sirhoax> nice.
[22:12:31] <sirhoax> can i get one.
[22:12:33] <sirhoax> yes sir.
[22:14:31] <sirhoax> http://www.flickr.com/photos/megacyclelabs/4597130635/lightbox/
[22:14:49] <sirhoax> wanted to add a small dvdr burning diode.
[22:15:01] <sirhoax> to the list of mods for this cnc. ;o)
[22:15:23] <sirhoax> not sure how it may or may not work.
[22:15:41] <Jymmm> frysteev: you bought that?
[22:16:16] <frysteev> yup
[22:16:39] <Jymmm> how much?
[22:16:51] <frysteev> guess :P
[22:16:52] <Jymmm> and does it work?
[22:17:05] <frysteev> dunno yet
[22:17:31] <Jymmm> it's been 2 months, whats the problem?
[22:18:10] <frysteev> free time!
[22:18:42] <Jymmm> no excuse
[22:19:29] <frysteev> been finishing off a job that paid for it
[22:20:19] <frysteev> :-)
[22:22:02] <frysteev> i will keep ya posted tho
[22:23:13] <Jymmm> $10 USD
[22:23:46] <frysteev> $2500 CDN
[22:24:06] <Jymmm> Is the company that made the laser tube local?
[22:25:36] <frysteev> no
[22:25:45] <Jymmm> Not in Canada?
[22:25:46] <frysteev> its a rofin sinar
[22:26:05] <frysteev> i have all the docs on
[22:26:25] <Jymmm> Fuck the docs, can you get another tube if you need to?
[22:26:53] <frysteev> hey, if he laser is dead, ill just use it as a plasma setup.
[22:27:46] <Jymmm> that's poor thinking. Work on reviewing the laser
[22:27:58] <Jymmm> reviving
[22:28:23] <Jymmm> Is it a sealed tube?
[22:29:16] <frysteev> that is the plan, but i always have a worse case scenario is what im saying
[22:29:36] <Jymmm> ah, ok.
[22:29:53] <Jymmm> frysteev: are there gas tanks with it?
[22:29:59] <Jymmm> of a place for them?
[22:30:11] <Jymmm> compressed gas
[22:30:14] <frysteev> http://www.rofin.com/index.php?id=100&L=1
[22:30:21] <frysteev> gas tanks yes
[22:30:37] <frysteev> dofin sinar dc 015
[22:30:50] <Jymmm> Oh, cool. then you just need to get the assorted gases. Should be 4 I think.
[22:31:14] <frysteev> it has a premix i believe
[22:31:44] <Jymmm> Eh, tha's okey too. You can have that done at any welding supply house
[22:32:13] <frysteev> :-)
[22:32:31] <frysteev> planning to fire up the cpu this weekend and start sorting it out
[22:33:29] <Jymmm> You in Ontario?
[22:33:38] <frysteev> yup
[22:33:50] <Jymmm> they have an office there
[22:34:01] <Jymmm> http://www.rofin-canada.com/en/
[22:34:09] <frysteev> yup
[22:34:35] <frysteev> the control side is a control techniques fnc5
[22:35:07] <Jymmm> You'll just need to make sure the RF Exciter is working.
[22:35:57] <frysteev> ya
[22:36:12] <Jymmm> Well, GIT ER DONE already!!!
[22:36:58] <frysteev> lol! demanding
