[01:10:48] <Valen> a friend of mine is desiging up a baby spindle for his toy cnc (;-P) anyway at one stage i had a pdf from a bearing manufactuer that had cutaways of heaps of spindle layouts
[01:10:53] <Valen> now i cant find it
[01:10:56] <Valen> any suggestions?

[01:22:50] <clytle374> I'm celebrating 2 years of not posting on reddit

[03:15:54] <seb_kuzminsky> i have a 3-phase main panel, what do i need to do to get 240V 1-phase out of it?
[03:17:38] <clytle374> 2 wires
[03:18:10] <clytle374> as long as it's 240 3 phase
[03:19:01] <seb_kuzminsky> an AC multimeter reads about 208 between any of the three phases, and 120 between any phase and ground
[03:19:38] <Jymmm> seb_kuzminsky: Stop feeding the hamster so much =)
[03:20:12] <seb_kuzminsky> "feeding the hamster"?? is that some kind of code phrase?
[03:20:17] <clytle374> If 208 isn't enough, you need a transformer
[03:20:41] <clytle374> I think the 208 is due to the legs not being 180degs out
[03:20:47] <Jymmm> seb_kuzminsky: as in hamster wheel power!!!
[03:21:10] <clytle374> Voltage to so hot around here, we get 240V... Or more
[03:23:35] -!- BobGreen [BobGreen!~vircuser@dhcp-0-27-19-d4-2c-49.cpe.mountaincable.net] has parted #emc
[03:25:03] <clytle374> 120V x SIN60= 103.9 well it adds up to that amount anyway
[03:26:44] <jdhNC> 120 * sqrt(3)
[03:27:51] <jackc> ya, cant pull 240 out of 208 three phase without a transformer
[03:29:59] <seb_kuzminsky> yeah that sucks
[03:30:06] <skunkworks_> seb_kuzminsky: whatcha need 240 for?
[03:30:12] <seb_kuzminsky> maybe i can get jymm and his gerbils to come help out
[03:30:23] <seb_kuzminsky> some dude wants to install a mig welder
[03:30:32] <jdhNC> how much power do you need out of it?
[03:30:42] <seb_kuzminsky> not sure
[03:30:49] <jackc> this isnt your house, right?
[03:30:54] <seb_kuzminsky> not my house
[03:31:04] <jackc> i mean, whatever is fed by 208 prolly already *has* a transformer to something useful
[03:31:18] <jackc> unless youre area of the shop only has that 208 feed for something that used to be there :-p
[03:31:20] <jdhNC> might work fine on 208
[03:31:23] <seb_kuzminsky> yeah, i bet the welder can be wired for 208
[03:31:30] <jackc> what kinda welder?
[03:31:47] <seb_kuzminsky> i'm really not sure, some kind of mig
[03:31:57] <clytle374> Should be okay
[03:32:39] <jackc> its just a bigass dc power supply anyway, itll deal ;-)

[03:55:16] <morfic> anyone here use a tcouhscreen?
[04:05:31] <clytle374> No touch screen with emc, but lots of experience with them on cncs. okay, if you can keep your hands mostly clean
[04:05:58] <Tom_itx> seldom happens in a machine shop
[04:06:20] <clytle374> That too is my experience
[04:10:58] <Jymmm> My hands are perfectly clean
[04:11:31] <Jymmm> the disposable gloves are filthy though =)
[04:16:19] <Jymmm> Chemicals just rip the crap out of my hands anymore.
[04:16:42] <clytle374> pencil erasers work decent on the screen
[04:17:09] <Jymmm> taking off the coating off it you mean?
[04:25:35] <clytle374> does it?
[04:25:59] <clytle374> boss probably knew and was hoping to sell screens
[04:26:04] <Jymmm> Well, there is usually a anti-glare coating on most displays.
[04:37:31] <morfic> i have just have a real glitchy "mouse pointer"
[04:38:20] <morfic> based on the hidDeviceDump, i get a second set of X and Y Coordinates that match the mouse when it is connected, but still occur when it is not connected and not configured in xorg.conf

[12:00:08] <Ekkeri> I gave up with my 2800+ AMD system
[12:01:15] <Ekkeri> I think someone should add Matrox G400 to non compatible graphic card
[12:01:28] <Ekkeri> it has some serious open gl issues
[12:02:32] <Ekkeri> not 100% sure if there are proper drivers thou
[12:03:41] <Ekkeri> I was getting >1500000ns jitter with it
[12:05:18] <Ekkeri> http://wiki.linuxcnc.org/emcinfo.pl?TroubleShooting#On_board_video "Avoid anything nvidia. Old matrox (millenium, G400, G450 era) work great. Some older ATI work great, not so sure about recent stuff." hmm..
[12:06:06] <Ekkeri> sadly there isn't any G400 in here, so not sure if it was it or something else: http://wiki.linuxcnc.org/emcinfo.pl?Latency-Test
[12:07:02] <Ekkeri> but yeah, gave up and bought something that should work :)

[13:03:32] <Ekkeri> and install to that 3/7 step :)
[13:03:58] <Ekkeri> but I made a new one, step 1/7 now :)
[13:04:00] <jthornton> I've only installed with a CD

[21:00:17] <awallin> tom3p: nice work on the graph-editor for HAL!
[21:00:38] <tom3p> what are your thoughts?
[21:01:01] <tom3p> thx! ( sorry i thiught i might miss you )
[21:01:47] <awallin> it looks good. if the graph editor can be used to load, create, save HAL netlists, and maybe draw/visualize for documentation then it is a good step forward
[21:02:14] <awallin> what about dependencies? does it require much beyond the standard emc2 distribution?
[21:02:33] <tom3p> the ide i have is: a cmd line tool to parse .hal files into .py files for Vision, and a cmd line too to cnvrt Vision's .py files into .hal
[21:02:53] <tom3p> re deps: none that are tricky to get for ubuntu lucid
[21:03:41] <tom3p> re the idea: and Vision just a handy viewer/editor ( so an input & output filter, looks like it'd be python )
[21:03:52] <awallin> could the added info needed in vision's fileformat be included in HAL as comments?
[21:04:25] <tom3p> hmm, well theres a spot in the widgets for comments, so it could be exported,
[21:04:53] <tom3p> but where are comments now in a hal component,.. there is a place, yes can be done
[21:04:56] <awallin> I'm thinking I don't want to maintain separately a py file and a HAL file for my config
[21:05:37] <tom3p> um , i thinking one file but you can cnvrt/translate between the 2 automaticly
[21:06:02] <tom3p> i mis read..
[21:06:39] <tom3p> hal will require a hal file done and Vision requires a .py file done... i'm not up to rewriting either :;
[21:06:53] <awallin> HAL has more than the "net" list. Did you think about threads too?
[21:07:05] <tom3p> i just would provide a path between the two, and a visualization
[21:08:28] <awallin> if you put it online I might look at it (weekend?)
[21:08:35] <tom3p> yes, threads are like micha (?) and i did in gEDA/eagle, they are object that are wired to. the eagle concept was like a 'global' widget for all to use
[21:09:12] <awallin> good. that means the graph/diagram has most (all?) of the information in the HAL file
[21:09:22] <tom3p> still a work in progress, to prove the idea i am writing the stepper-mm config and its parts. so i have a real example to look at
[21:10:18] <tom3p> i did work out parameters, but not io ( opposed to i and o , the weird pins that are both )
[21:10:42] <tom3p> graph theory dont like hermaphroditic pins
[21:11:18] <jdhNC> who does.
[21:11:41] <tom3p> really im doing this because i have trouble reading such nets, and it seems like its visual in nature
[21:12:02] <tom3p> (damn herma pins ;)
[21:13:42] <tom3p> it has the abiltity to subnet, so i should be able to hide some complexity ( opposed to zooming on a plate of spaghetti, remove a bunch a leave a black box for 'lotsaglueneededforTHC' ) with a few pins )
[21:14:10] <tom3p> ok, will shut up a work on it ,thx!

[21:45:34] <tom3p> its expired, making new quicky now
[21:47:07] <Ekkeri> ok, so I had a right link then :)
[21:47:26] <tom3p> haha i only set those for a day at most
[21:48:27] <Ekkeri> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?AVR sad that there isn't any visible enthusiasm with this :/
[21:48:33] <Ekkeri> I kinda like AVRs
[21:50:01] <Ekkeri> I has thinking to add XYZA positions in 20x4 LCDs with big font, like a DRO
[21:50:37] <clytle374> I like the idea
[21:51:22] <Ekkeri> http://www.instructables.com/image/FG7T52WGJHVKYW2/Big-Number-Clock-on-LCD.jpg like that, I have 6pcs those 20x4 already :)
[21:52:13] <clytle374> I'm looking to change the font in Axis, I found a thread saying there is a thread.... but never found the thread
[21:52:29] <Ekkeri> :P

[23:20:17] <A2Sheds> Just FYI I stopped by http://www.kelinginc.net/index.html today. Really nice guy with lots in stock.
[23:20:55] <Valen> shipping motors to australia is kinda a killer though lol
[23:22:31] <A2Sheds> heh, he imports from China, easier for you to buy direct
[23:23:15] <A2Sheds> Valen: are there any t-slot makes in Australia?
[23:23:23] <A2Sheds> makes/makers
[23:23:25] <Valen> dunno
[23:23:46] <Valen> we were just going to get extrusion and make it when we were looking at making a mill
[23:23:57] <A2Sheds> I'm working on a DIY kit for photopolymer 3dp
[23:24:17] <Valen> the resins are spendy for that i hear?
[23:24:30] <A2Sheds> that was the rumor
[23:24:35] <A2Sheds> but no longer
[23:24:53] <Valen> I do wonder about using a plain uvset polyester
[23:25:00] <A2Sheds> $40-200/L depending on formula
[23:25:08] <Valen> thats pretty spendy still
[23:25:29] <Valen> i think you can get uvset for a few $ a kg, the stuff they use for fiberglass
[23:25:34] <A2Sheds> we're actually going to manufacture some of the resins in Melbourne
[23:25:51] <Valen> your ausie A2Sheds?
[23:26:09] <A2Sheds> no, I have a tech partner there
[23:26:23] <A2Sheds> inks, fluids, printers
[23:26:31] <Valen> I C
[23:26:40] <A2Sheds> https://code.google.com/p/lemoncurry/wiki/main
[23:27:05] <A2Sheds> we start mixing next month
[23:27:24] <Valen> have you looked at the regular uv set stuff?
[23:27:38] <Valen> might be a bit slower perhaps
[23:27:45] <A2Sheds> yes, there are several ways to do it
[23:28:01] <A2Sheds> yeah slower and different wavelengths
[23:28:10] <Valen> my father used to be in the fiberglass trade
[23:28:29] <Valen> going through 44's of resin every 2/3 days
[23:32:12] <clytle374> A2Sheds, did you look at any of the pendants?
[23:33:44] <A2Sheds> they were sitting out, but I didn't pick one up
[23:34:02] <A2Sheds> I'm going back in about a week
[23:35:19] <A2Sheds> Valen; yeah, we buy in 55 gal drums
[23:36:21] <clytle374> If you don't mind look one over. Like does it feel cheap, and how the wheel feels.
[23:36:42] <A2Sheds> sure, next time
[23:36:53] <A2Sheds> all the motors looked nice
[23:37:03] <Valen> I want to get the xbox controller hooked up for jogging ;->
[23:37:14] <A2Sheds> he shops around China for higher quality parts
[23:37:53] <PCW> A2Sheds: I notice 400 nM diode lasers are pretty cheap
[23:38:28] <A2Sheds> yes, prices are dropping
[23:39:47] <A2Sheds> I priced 30W UV 385nm leds 90 days ago , now they are 1/2 the price
[23:40:03] <PCW> I guess 2D laser steering is more expensive than DLP+optics
[23:40:39] <A2Sheds> I'm going to DIY a laser printer next for submicron res small parts
[23:40:57] <A2Sheds> DLP is also faster
[23:40:58] <PCW> but probably better image quality/contrast
[23:41:36] <A2Sheds> DLP is fine, same for LCD. I wish I could find very small pitch LCD panels
[23:41:42] <PCW> Faster than a scanned laser 1-2 W laser?
[23:41:44] <Valen> 2d laser steering should be fairly cheap
[23:42:03] <Valen> stick the UV laser in the guts of the chinese laser cutters everybody seems to be getting ;->
[23:42:40] <A2Sheds> it's also a factor of curing an entire/layer slice at a time vs a point
[23:43:06] <A2Sheds> multi head laser array
[23:43:06] <Valen> might be worth looking at anyway as people seem to have them so you could potentially make use of the existing hardware
[23:43:38] <andypugh> Oooh! Teeny screws to buy! (just getting some M3 low-head capscrews)
[23:43:41] <andypugh> http://www.pts-uk.com/Products/00030003
[23:43:57] <A2Sheds> I'm not even done with this one and everybody is asking for a laser system :)
[23:44:03] <A2Sheds> maybe next month
[23:44:17] <Valen> lol
[23:44:21] <andypugh> A2Sheds: Galvanometer style?
[23:44:33] <Valen> andypugh: we use 1.6m screws in our torches
[23:44:38] <Valen> 1.6mm
[23:44:48] <A2Sheds> EMC controlled 2 axis mirrors
[23:44:49] <Valen> I want to get a milling tap for it
[23:45:05] <Valen> heh might not be quick enough for it ;->
[23:45:22] <andypugh> That site has screws down to M1, and socket screws down to M4.
[23:45:45] <PCW> I would thing laser prism for X. stepped stage for Y
[23:45:57] <A2Sheds> it's hard enough trying to find a 1mm allen wrench/key
[23:46:11] <A2Sheds> I had to buy a whole set to get one
[23:46:19] <Valen> andypugh: nice
[23:47:10] <andypugh> Sorry. I meant socket screws down to M1.4, M4 is commonplace
[23:47:32] <clytle374> Yeah, my rc heli is full of 1.4mm, hard to find
[23:47:49] <andypugh> I nearly bought some, just to have them :-)
[23:48:00] <clytle374> search gaui 200 parts if you need 1.4mm screws
[23:48:55] <andypugh> clytle374: That site is probably cheaper, though the tiny ones are £20 per hundred (and sold in 25s)
[23:49:54] <A2Sheds> http://www.ebay.com/itm/10W-High-Power-LED-UV-Purple-400-405nm-20-30LM-/110732167964?pt=LH_DefaultDomain_0&hash=item19c826cb1c
[23:50:05] <A2Sheds> US $31.99
[23:50:23] <clytle374> first on the list is $33 for 25
[23:50:40] <clytle374> 1.6 is much cheaper
[23:50:53] <andypugh> clytle374: Which list?
[23:51:32] <clytle374> This site you linked
[23:51:37] <A2Sheds> andypugh: how is the motor coming along?
[23:51:37] <clytle374> the
[23:52:32] <andypugh> clytle374: No, that's £21.18 per hundred, sold in 25s. (so about £5 for 25 of them)

[23:53:08] <andypugh> A2Sheds: Waiting for an encoder PCB that isn't stupidly wrong.
[23:53:40] <clytle374> andypugh, that's a confusing way to do it. gaui screws are about $3 for 10
[23:55:06] <clytle374> are those delta AC servos any good?
[23:55:18] <clytle374> Was looking at maybe using sureservo
[23:56:13] <andypugh> Link?
[23:56:50] <andypugh> I wonder what that UV LED is for? 110 degree bean angle is going to be hard to collimate, and the emitting area looks big.
