[00:01:01] <DaViruz> http://www.vimeo.com/10312562
[00:01:07] <DaViruz> that's the closest i've come to cnc turning
[00:01:09] <Paragon39> and one of these http://www.youtube.com/watch?v=hP9Uaqv5v5Y
[00:01:13] <DaViruz> and i ended up crashing the tool :/
[00:01:38] <cradek> those have ballscrews right?
[00:02:03] <Paragon39> The starmill is EMC controlled and I have upgraded the steppers ... Cradek they do have ballscrews
[00:02:17] <cradek> yep they are nice little machines
[00:03:52] <Paragon39> I replaced the little steppers with nema 23 double stacks from Motion Control the controllers are from the same company... I think they are listed on the EMC hardware wiki page.
[00:04:00] <DaViruz> wow, one of those is exactly what i need, instead i ended up getting a vmc with 1.5m travel :/
[00:04:24] <theorb> theorb is now known as theorbtwo
[00:05:12] <Paragon39> DaViruz: To be honest the travell is very small... from memory x140 y90 Z120 mm I think...
[00:06:02] <Paragon39> Though this guy made this with one! http://www.craftsmanshipmuseum.com/Tomlinson.htm
[00:06:50] <DaViruz> that is impressive
[00:07:26] <Paragon39> Sure is :-) .... Guy must have a lot of spare time on his hands huh ... lol
[00:10:20] <Paragon39> DaViruz: Im guessing your in Europe... ?
[00:10:27] <cradek> someone always says that whenever someone else does something he can't - I don't understand it
[00:11:15] <DaViruz> Paragon39: yeah, sweden
[00:12:03] <Paragon39> What the time thing? I agree with you! I couldnt make it but he must of invested a great deal of time and skill right! I take my hat off to him!
[00:15:10] <DaViruz> speaking of time, i'm way past bed time
[00:15:44] <Paragon39> DaViruz: CU
[00:40:26] <ries_> ries_ is now known as ries
[06:30:06] <ries_> ries_ is now known as ries
[14:09:24] <SteveStallings> SteveStallings is now known as steves_logging
[15:19:49] <SWPLinux> morfic, morficmobile, mozmck: know anyone in the Dallas area with an AVR in-circuit programmer?
[15:20:04] <SWPLinux> or a place to buy one (on a Sunday morning, much like today ...)
[15:20:20] <skunkworks> eww - yeck
[15:20:31] <cpresser> SWPLinux: build one yourself.. you only need few 10k resistors
[15:20:43] <mozmck> me?
[15:21:08] <mozmck> I have a dragon and an JTAGICE-MKII
[15:21:45] <SWPLinux> cpresser: that only works if you have a computer with a parallel port available
[15:22:09] <SWPLinux> mozmck: care to come to Downtown Dallas with that? :)
[15:22:13] <cpresser> damm.. I own a USB-Programmer, which i dont need.
[15:22:14] <Jymmm> SWPLinux: and your craptop has one,
[15:22:17] <SWPLinux> I'll buy you coffee or lunch or whatever
[15:22:19] <cpresser> but its locatd in germany :D
[15:22:28] <SWPLinux> Jymmm: excuse me but fuck off. This isn't the time :)
[15:22:47] <Jymmm> SWPLinux: you dont have a paraport on it?
[15:22:53] <SWPLinux> my spares are in Vermont
[15:23:49] <mozmck> SWPLinux: I can probably do that. The JTAGICE I have right here, will that work?
[15:25:44] <SWPLinux> mozmck: I think so. I believe AVRDude works with that
[15:26:09] <SWPLinux> that's USB, right?
[15:26:17] <mozmck> Yep, I've used it. It has the 10-pin header on it. USB - yes
[15:26:21] <SWPLinux> awesome
[15:26:30] <SWPLinux> got a 10 -> 6 pin adapter?
[15:26:38] <SWPLinux> (or does it also have the 6-pin header?)
[15:26:52] <SWPLinux> well, if you're willing, I'd really really really appreciate it
[15:27:18] <mozmck> It'll take me an hour to get there, but I'm willing.
[15:27:25] <SWPLinux> mine died at about 2:00 this morning, just as I was about to test (what I think is) the last bug fix in the new camera trigger controllers
[15:27:33] <SWPLinux> 5626 Alta Avenue
[15:27:42] <mozmck> No 6-pin that I know of. Let me look and see what kind of adapters I might have.
[15:28:12] <SWPLinux> ok, it's easy enough to make an adapter with parts from a local Radio Shack (all of which I know the locations of :) )
[15:28:21] <skunkworks> heh
[15:30:31] <cradek> who's going to fest in wichita Nov 12? I'm thinking about calling up the Candlewood suites and asking for a special rate for our group.
[15:34:30] <mozmck> cradek: I may be able to make it, but I might also have another place to stay.
[15:37:38] <Jymmm> SWPLinux: There's a Frys 20 miles (30m) away... 2488 market place blvd, Irving, TX 75063
[15:37:55] <SWPLinux> I wonder if Fry's sells AVR programmers :)
[15:38:02] <SWPLinux> I think there's one closer as well
[15:38:21] <SWPLinux> and also Best Buy, if I wanted to get a parallel port card for one of the desktops
[15:39:22] <Jymmm> 9 miles (17m) 12710 executive drive, Dallas, TX 75238 (Fry's Electronics)
[15:40:38] <skunkworks> I don't think I am going to make it to Wichita this time. To many trips this year ;)
[15:40:40] <cradek> mozmck: cool, hope you can make it
[15:40:53] <cradek> skunkworks: darn! you have your own fun project too.
[15:41:01] <skunkworks> right - it is going well
[15:41:25] <SWPLinux> skunkworks: oh come on - what's too many trips? :)
[15:41:28] <skunkworks> cradek: did you see - http://www.youtube.com/watch?v=22dWg3GbywE
[15:42:04] <skunkworks> heh - wife is in ireland right now with some family friends...
[15:42:42] <cradek> what am I seeing?
[15:42:56] <Jymmm> cradek: the red thing spinning
[15:43:10] <Jymmm> on left
[15:43:20] <cradek> ok right
[15:43:22] <cradek> :-)
[15:43:31] <Jymmm> first base
[15:43:44] <cradek> I didn't see anything at first, just heard a loud hydraulic pump, heh
[15:43:56] <cradek> skunkworks: so does it change gears correctly? and at the right time?
[15:44:05] <skunkworks> so far :)
[15:44:09] <Jymmm> and the LEDs on thr right
[15:44:15] <cradek> I saw you posted your component - I didn't read it though :-)
[15:44:24] <Jymmm> 'CLICK' == led changes
[15:44:31] <skunkworks> the formating got lost in the email - so it really sucks to look at.
[15:44:54] <cradek> ah
[15:45:15] <skunkworks> yes - you can see the bottom 4 of the top 5 ssr's count up in binary.
[15:45:21] <cradek> did you get the tool clamp to work? how about orient?
[15:45:34] <cradek> seems like you're so close to having it usable
[15:46:06] <skunkworks> the wires are run for the hydraulic pump that does the collet clamp/ table lift/clamp. just not hooked up yet
[15:46:12] <Jymmm> skunkworks: "No panduit was harmed in the making of this film"
[15:46:48] <skunkworks> dad is trying to get the way lube working for the y axis. seem to have some plugged and or miss adjusted oiling
[15:47:43] <cradek> lube is the least glamorous part of restoring a machine
[15:48:02] <skunkworks> the spindle orient is next. (it should be pretty easy - just needs to be in a certain gear, creep ccw and activate a lock solinoid.
[15:48:11] <cradek> after running mine for a year or two I really should check flow from all the nozzles again
[15:48:50] <cradek> cool, sounds easy
[15:49:43] <skunkworks> y never really oiled correctly. we did figure out that the x/z oiling is done by a bijor pump that is activated by the z clutch. (which isn't actually there anymore - but the solenoid is - and it all seems to work. cycled it a bunch and oil started flowing on the ways
[15:50:26] <Jymmm> SWPLinux: I'd hit frys instead of RS for idc parts
[15:50:45] <skunkworks> cradek: the last gear ran the spindle up to 3000 rpm.
[15:50:54] <skunkworks> I think that will be max
[15:51:15] <Jymmm> SWPLinux: Pin 1's... http://www.solarbotics.com/products/14190/?utm_source=Google&utm_medium=Product+Search&utm_campaign=Product+Search+%28Oct10%29
[15:51:20] <cradek> do you have a different machine for smaller work (1/4 and 1/8 tools)?
[15:51:38] <cradek> oh you have a high speed spindle, I forgot
[15:51:52] <skunkworks> we have a gantry router.. but we also have a couple of high speed spindle options we made for the K&T
[15:51:53] <skunkworks> right
[15:52:31] <skunkworks> dad says he also has a 6 or 7 to 1 speeder that he would like to try some day.
[15:52:57] <cradek> that'd be nice
[15:53:34] <Jymmm> skunkworks: whats the highest speed in that video?
[15:53:38] <skunkworks> 3000rpm
[15:53:43] <Jymmm> k
[15:53:54] <skunkworks> at the spindle - the spindle motor is close to 4000
[15:54:16] <skunkworks> there is always a reduction in the transmission
[15:54:29] <Jymmm> gotcha
[15:55:48] <SWPLinux> Jymmm: that's kind of cool
[15:57:13] <Jymmm> SWPLinux: Well, I thought it would at least give you the pin 1's if you need to make it, just not sure what the middle connector is
[15:58:46] <SWPLinux> I think that's so you can use it as a 10-pin to 10-pin cable, or 10-6 or 6-10 pin
[15:58:58] <Jymmm> gotcha
[15:59:08] <SWPLinux> (but not 6-6, which is what's included with all the new AVRISP mkII programmers)
[15:59:20] <Jymmm> Nice... NOT!
[15:59:50] <Jymmm> SWPLinux: But why can't you use your craptop? It has a parallel port on it
[16:00:39] <cradek> SWPLinux: I bet you could run avrdude on any desktop machine booted from an ubuntu cd
[16:00:56] <cradek> or do you have no desktop machines around at all?
[16:01:00] <skunkworks> oh - and I want to make a 'at speed' signal out of my comp. (that should be pretty easy also)
[16:02:40] <skunkworks> dad said if I would have move the camera over just a few inches - you could have seen the display of the vfd. (rpm)
[16:02:45] <skunkworks> oh well
[16:02:47] <skunkworks> ;)
[16:03:18] <skunkworks> you can see the vents on the vfd in the lower right of the frame.
[16:07:06] <SWPLinux> cradek: I have my new laptop and two desktops here, all with Ubuntu 9.04 or 10.04
[16:07:28] <SWPLinux> Jymmm: I only have my small laptop here, the 4.8 pound one with no serial or parallel ports
[16:07:41] <SWPLinux> (that lasts 10 hours on a charge)
[16:07:44] <SWPLinux> or more
[16:08:12] <SWPLinux> Jymmm: don't you remember why you started calling my laptop a craptop?
[16:08:33] <SWPLinux> it's because it *doesn't* have a parallel port. "all that power and it still can't run a mill"
[16:08:48] <Jymmm> SWPLinux: LOL, you're right, I totally forgot.
[16:08:53] <SWPLinux> prick :)
[16:09:41] <Jymmm> SWPLinux: Stop being so sensative. At least my craptop has a paraport ya whiny whore!
[16:10:33] <Jymmm> SWPLinux: and only 768MB =(
[16:11:01] <Jymmm> SWPLinux: and a 45m battery life on a NEW battery and fully charged
[16:12:05] <Jymmm> oh, and a built in fdd right next to the DVD-RW =)
[16:14:13] <Jymmm> SWPLinux: and yours is so huge! How do you like the 4.5lb one?
[16:14:31] <Jymmm> SWPLinux: for travel that is
[16:19:52] <qq-> so a laptop w/o parallel port cant run emc2 ?
[16:20:01] <qq-> can't*
[16:21:13] <SWPLinux> a laptop is a bad idea anyway
[16:21:39] <SWPLinux> Jymmm: the new laptop is great, except that the screen is only 1366x768
[16:21:44] <fragalot> \o/ I've returned from theblack abyss
[16:22:12] <SWPLinux> it's about the same speed as the other one, which was a Core2 Duo 2.2 GHz
[16:22:12] <fragalot> SWPLinux: that's default resolution nowadays isn't it
[16:22:29] <SWPLinux> yeah, bummer isn't it
[16:23:12] <psha> SWPLinux: not too bad :) my small laptop has only 1024x640 :)
[16:23:46] <skunkworks> * skunkworks has 1920X1080....
[16:23:55] <qq-> why is so important the screen resolution ?
[16:24:01] <psha> 1024x600 i mean
[16:24:05] <SWPLinux> my other laptop is 1920x1200
[16:24:28] <skunkworks> where is cradek? ;)
[16:24:40] <psha> on dev channel :)
[16:24:50] <qq-> skunkworks, next room -devel
[16:27:01] <psha> is it possible to clear polyurethane foam from hands/cloth? :)
[16:29:34] <Jymmm> SWPLinux: oh that sucks. Gotta love 2048x
[16:29:52] <SWPLinux> no kidding. did you see the replacement LCD I linked to a week or so ago?
[16:29:59] <Jymmm> no
[16:30:02] <SWPLinux> 2048x1536, 15" (!)
[16:30:08] <SWPLinux> 4:3 ratio, of course
[16:30:25] <Jymmm> of course
[16:30:36] <SWPLinux> cradek was able to stick one in his thinkpad, with a few cable modifications
[16:31:33] <Jymmm> how you do that?! Does it depend on the laptop supporting that resolution?
[16:31:40] <Jymmm> doesn't
[16:31:50] <SWPLinux> it was a Thinkpad display in the first place
[16:31:59] <Jymmm> OH! ok.
[16:32:13] <Jymmm> a replacement upgrade
[16:32:17] <SWPLinux> I think not for the particular model he has, but he was able to get it to work
[16:32:23] <SWPLinux> yeah, and $90 or so, IIRC
[16:32:30] <Jymmm> not bad
[16:32:51] <SWPLinux> I ordered a 1600x900 from Papatek for this little laptop, I'll have to see if it works some day
[16:33:40] <Jymmm> SWPLinux: See dude, if you lived here you could just go pick it up.
[16:34:16] <Jymmm> Frys-a-plenty, walk to ECS, etc
[16:35:39] <Jymmm> SWPLinux: and could easily fly to HK/China and bring in some cool toys to "play" with =)
[17:10:30] <morfic> SWPadnos: sorry, no
[17:16:33] <qq-> Jymmm, where you live ? ;)
[17:18:39] <Jymmm> qq-: Compton CA. Home of the LA Riots and the inspiration/model for Grand Theft Auto: San Andreas

[21:35:06] <mikegg> I got some used kurt D 40 vises coming my way
[21:35:21] <mikegg> pretty excited
[21:36:10] <mikegg> I got the pair for $425 with shipping. hope they're in decent shape...

[22:31:00] <mikegg> http://www.validusgroup.com/Search.aspx?k=kurt
[22:31:19] <mikegg> I bought the two on the outside. they've got one more for sale
[23:22:01] <kgartner> is there a way to remap physical pins on the mesa cards other than recompiling the vhdl source?
[23:22:35] <cradek> nope
[23:23:13] <cradek> well technically yes - you can ask someone else to build it for you - pcw does this for folks routinely, but then you're faced with problems updating because your firmwares are different.
[23:24:29] <kgartner> right, well,l guess I'll get back to seting up this build environment :)
[23:25:23] <kgartner> at least I know I'm barking up the right tree, thanks
[23:27:37] <cradek> what kind of rearrangement do you need? are you trying to save a connector?
[23:28:56] <kgartner> yea, I'm just trying to cram all the outputs on one side of the IO board
[23:29:39] <kgartner> I'd like to be able to do this for future projects as well so I don't mind putting the time up front to learn how to do it
[23:30:12] <cradek> I have avoided it so far :-)
[23:30:58] <kgartner> yea, I quickly got the impression that's what most people must do
[23:31:22] <kgartner> I am finding myself building too many 'one off' machines to do that
[23:32:14] <cradek> there's a nice variety of firmwares prebuilt... but yeah the wiring is fairly fixed, and meant to work most easily with the mesa daughter cards
[23:34:37] <kgartner> yea, maybe I'm just missing something but it didn't seem like there was one that fit with the 7i37
[23:34:59] <cradek> 7i37 is like the most popular daughter card ever - I promise you are missing something
[23:35:39] <kgartner> that's kind of what I thought, I'll keep poking around I guess
[23:35:41] <cradek> looking...
[23:36:26] <cradek> for the 7i37's 8 outputs, you set hm2_5i20.0.gpio.XXX.is_output and .invert_output to 1
[23:36:55] <cradek> I think that's it - then just wire 'em up
[23:37:46] <kgartner> yea, I need a pwm too, but I can find something with a pwm that lines up on the output
[23:38:11] <cradek> the optos may be too slow for pwm - usually a 7i33 is what you want for an analog out
[23:38:50] <kgartner> is there an advantage to running the stepgen stuff in firmware?
[23:38:57] <cradek> oh hell yes
[23:39:05] <cradek> perfect smooth steps at whatever speed you want
[23:39:18] <kgartner> mmmm, I like smooth :)
[23:39:45] <cradek> software stepgen is sometimes pretty limiting, especially if you have high-microstep drives.
[23:40:13] <kgartner> does the 7i33 use optos? I need optos for my spindle because it floats at mains voltage
[23:41:02] <cradek> you mean the pwm analog out of the 7i33? I don't know - let's look at the manual
[23:41:37] <kgartner> thought I'd ask if you knew off the top of your head, I can RTFM
[23:42:04] <cradek> I don't see anything about isolation - I assume not
[23:47:28] <kgartner> yea, I mean I ran the pwm through the opto anyways, it wasn't the most linear, but it worked
[23:48:24] <cradek> good enough for something like spindle speed
[23:48:47] <kgartner> yea, I'm not doing anything fancy here, don't even have an option to run it reverse
[23:49:05] <kgartner> I'd like to get a new controller, but haven't found anything good for a 180VDC motor
[23:49:24] <cradek> sounds weird
[23:49:32] <cradek> can you put a 3phase in its place and use a vfd?
[23:49:46] <cradek> how big is it?
[23:49:50] <kgartner> 1/2 hp
[23:49:59] <kgartner> I probably could rig something up
[23:50:41] <kgartner> but I'm not sure it's worth the effort for 5"x8" of travel
[23:54:42] <cradek> yeah depends how well stocked your junkbox is
[23:54:49] <cradek> 1/2 hp vfd can be pretty cheap
[23:58:37] <kgartner> yea, I've looked briefly, is that enough to do rigid taping? (with encoder) or does one need more power
[23:58:44] <kgartner> that would be my main motivation to upgrade
[23:58:54] <cradek> probably depends on the gearing
[23:59:02] <cradek> and the tap size
[23:59:59] <cradek> big taps (3/8 up?) take an awful lot of torque
