[00:01:09] <lerman_> lerman_ is now known as lerman
[00:18:17] <cradek> hi all
[00:18:50] <cradek> http://timeguy.com/cradek-files/emc/thread-done.jpg
[00:18:54] <cradek> http://timeguy.com/cradek-files/emc/thread-check.jpg
[00:18:58] <cradek> http://timeguy.com/cradek-files/emc/thread-cutting.jpg
[00:26:45] <cradek> ... the second thread cut with emc2's new lathe code
[00:33:58] <cradek> jmkasunich: hi!
[00:34:03] <cradek> jmkasunich: back home?
[00:34:26] <jmkasunich> yep
[00:34:36] <jmkasunich> you been a busy fellow!
[00:35:11] <cradek> ok, what have you heard, it's not true
[00:35:43] <jmkasunich> not just heard... I got pictures
[00:35:47] <jmkasunich> of threading ;-)
[00:35:51] <cradek> aw crap
[00:35:55] <cradek> oh THAT
[00:35:58] <cradek> haha
[00:36:13] <cradek> that second one looks pretty good doesn't it
[00:36:16] <jmkasunich> yeah
[00:36:36] <cradek> at first I just couldn't figure out why the passes wouldn't line up
[00:36:46] <cradek> ... then I tightened the set screw on the encoder
[00:36:50] <jmkasunich> lol
[00:37:05] <cradek> I always forget to check the obvious things first
[00:37:22] <jmkasunich> other than the the long shaft and top-of-motor mount worked out OK?
[00:37:30] <cradek> yep
[00:37:44] <jmkasunich> what did you do to hold the drawbar in?
[00:37:46] <cradek> it's a bit crappy but it works
[00:38:02] <jmkasunich> you should post a pic of the overall setup
[00:38:03] <cradek> I chopped off a bogus tool holder I had
[00:38:31] <cradek> I can do that, just a minute
[00:39:00] <jmkasunich> BTW, very nice macrophotography on the thread pics
[00:39:47] <cradek> thanks, I worked hard on them
[00:40:01] <fenn> cradek i'm impressed
[00:42:01] <jmkasunich> I bet its neat to watch it thread
[00:42:03] <cradek> http://timeguy.com/cradek-files/emc/lathe-setup.jpg
[00:43:16] <jmkasunich> that bench is just too clean
[00:43:34] <jmkasunich> whats holding the plate to the top of the motor?
[00:43:48] <cradek> not much...
[00:44:00] <fenn> that's a huge motor
[00:44:11] <jmkasunich> lol
[00:44:17] <cradek> it's a sherline motor with closed-loop speed control
[00:44:25] <cradek> it's really quite nice for the price
[00:44:38] <fenn> heh jmk you probably eat motors like that for breakfast huh
[00:44:43] <jmkasunich> what is it, about 1/8HP?
[00:45:02] <cradek> it doesn't say: "90 V DC motor" is all it says
[00:45:22] <jmkasunich> my POS shoptask is 3/4HP, the Van Norman is 1-1/2HP
[00:45:48] <cradek> I'm off to dinner - be back in an hour or so
[00:45:51] <jmkasunich> ok
[00:46:11] <jmkasunich> I want to replace the shoptask motor with a three phase one and add a VFD
[01:10:40] <jmkasunich> anybody know what development tools are needed to do FPGA design for a m5i20 card? are there free versions?
[01:23:01] <cradek> back
[01:23:24] <jepler> hi cradek
[01:23:28] <cradek> hi jeff
[01:23:33] <steves_logging> steves_logging is now known as steve_stallings
[01:23:54] <cradek> crap, still no cvs
[01:24:00] <jmkasunich> again?
[01:24:32] <cradek> yep.
[01:47:42] <cradek> jmkasunich: the sherline motor is apparently 1/3 HP
[01:48:06] <jmkasunich> wow
[01:48:21] <jmkasunich> at what speed? bet its very high
[01:48:55] <cradek> http://www.sherline.com/dimen.htm
[01:49:31] <cradek> you would be surprised at the power it has at extremely low speed like I was using today
[01:50:08] <cradek> a different set of pulleys would make it really strong
[01:50:16] <jmkasunich> not enough to cut a 3/8-16 thread tho
[01:50:28] <cradek> I dunno, it got pretty far
[01:50:37] <jmkasunich> yeah, the real answer to low speed torque will always be mechanical, not electrical
[01:51:03] <cradek> the whole machine may not be stout enough to finish that thread, no matter what's running the spindle
[01:51:32] <cradek> guess I should have cut 3/8-40 or something
[01:51:32] <jmkasunich> in the email you said "my spindle gives out"...
[01:51:39] <jmkasunich> what does that mean? it stalled?
[01:51:40] <cradek> but I was hoping to get a nut on it
[01:52:05] <cradek> yes, for the last several passes I was helping it turn.
[01:52:37] <jmkasunich> 0.0005 is as small as you can go on the infeed?
[01:53:07] <cradek> I have a scale of 6400 but those are half steps
[01:53:16] <jmkasunich> might also want to include spring cuts - passes made with no infeed at all
[01:53:21] <cradek> so .0003125 is probably the practical minimum
[01:53:29] <jmkasunich> I bet a spring cut will still remove a chip
[01:53:34] <cradek> yes, I should definitely do that
[01:53:45] <cradek> harder to do with an O loop unless I just do each cut twice
[01:54:01] <jmkasunich> that works
[01:54:18] <jmkasunich> unneeded in the early passes, but what the heck, its a CNC...
[01:54:25] <cradek> yep
[01:54:29] <jmkasunich> its not like you have to stand there turning the crank ;-)
[01:54:41] <cradek> I wonder if the canned cycle should use shallower passes as it gets further in
[01:54:57] <cradek> I doubt that's standard, but it seems like it might be useful
[01:55:10] <jmkasunich> I don't know much about canned cycles
[01:55:29] <jmkasunich> I was even thinking of a cycle that is just one pass (infeed, cut, outfeet, return to start)
[01:55:39] <cradek> I don't either, but we could make all of them we want
[01:55:44] <jmkasunich> and leave the number and depth of passes to the user
[01:55:50] <cradek> yeah
[01:55:55] <steve_stallings> Funny you should mention a hand crank, the Sherline threading kit includes just that!
[01:56:03] <cradek> steve_stallings: oh tell me about it
[01:56:15] <cradek> steve_stallings: I've cut threads in stainless with that abomination
[01:56:22] <jmkasunich> unless you have everything set up perfectly you'll have to test fit anyway
[01:57:18] <cradek> steve_stallings: I needed a left-hand metric thread and all I had was a sherline - how else am I going to get it?
[01:57:48] <steve_stallings> I should think that cutting any material that work hardens would be foolhardy on a Sherline.
[01:58:24] <cradek> I got a working part for just the cost of a few tools
[01:58:34] <jmkasunich> what kind of stainless?
[01:58:45] <cradek> trust me I looked for left-hand metric dies first, but I doubt there are any in the whole US
[01:58:56] <cradek> jmkasunich: umm, the silver shiny kind
[01:59:10] <jmkasunich> I bet it wasn't 316
[01:59:36] <cradek> really no idea
[01:59:51] <jmkasunich> 316 work hardens on each pass, and the next pass needs to be deep enough to get under the work hardened layer from the previous pass
[02:00:01] <jmkasunich> a sherline simply isn't rigid enough to cut that deep
[02:00:02] <cradek> yikes
[02:02:30] <jmkasunich> I was once drilling some 5/16" or so holes in 1/8" thick 316SS sheet to make a boat part
[02:02:43] <jmkasunich> if you pressed like hell (drill press) it would do OK
[02:03:12] <jmkasunich> but on one hole I let up for just a split second, and the drill was no longer cutting under the work hardened layer...
[02:03:27] <jmkasunich> as soon as I pressed down again, the end of the drill bit got red and crumbled
[02:04:18] <cradek> sounds really hard to recover from that
[02:04:33] <jmkasunich> I recovered by getting a new piece of steel and a new drill bit
[02:05:00] <jmkasunich> fortunately the part was simple, 1" wide, 3" long, rounded ends and 2 holes
[02:05:12] <jmkasunich> it would have really sucked if I had several hours in it
[02:09:35] <jmkasunich> cradek: they must be using sears HP
[02:09:49] <jmkasunich> 0.06kW != 1/3HP, its less than 1/10!
[02:09:53] <cradek> jmkasunich: I made /compile_farm point to the one in your home directory
[02:10:08] <cradek> now it says 03/12, can you update it now?
[02:10:37] <jmkasunich> I should be able to
[02:10:48] <jmkasunich> but I don't have anything to put on this box
[02:10:58] <cradek> I don't understand
[02:11:12] <jmkasunich> I need to change the farm slots to use my account and pw when they ftp results
[02:11:54] <jmkasunich> this box is my working machine, not a farm machine, it doesn't have a more current copy of index.html or anything else that I would want to put up on the server
[02:12:12] <cradek> ok, I just assumed you would have to fix the farm itself
[02:12:37] <jmkasunich> I either have to fix the farm to use my account, or have SWP give the farm its own account
[02:12:38] <jmkasunich> I
[02:12:51] <jmkasunich> I'd prefer the later, but the former works
[02:13:15] <jmkasunich> since you were able to redirect to my account, I'll do that
[02:13:18] <cradek> I assume he meant for you to use the jmkasunich account, I think otherwise there's no purpose for it
[02:13:36] <cradek> there's no cradek account, so he didn't make them for all of us
[02:13:47] <jmkasunich> ok
[02:14:07] <cradek> you'll have to copy over an ssh key and stuff I assume
[02:14:09] <jmkasunich> the day he set it up we were talking about compile farm mark II, with some server side stuff to make it nicer
[02:14:13] <cradek> oh wait, you use ftp
[02:14:34] <cradek> while you're at it, you should fix your scripts to use scp
[02:14:50] <jmkasunich> too much like work
[02:15:08] <jmkasunich> when I get the new (qemu based) farm going I'll look into that
[02:15:12] <cradek> ok
[02:15:32] <jmkasunich> speaking of which, they were scrapping another of those LPr servers
[02:15:41] <jmkasunich> I got another 256M of ram
[02:15:47] <jmkasunich> a couple spare 18G disks
[02:15:49] <cradek> cool
[02:16:02] <jmkasunich> now I basically have one complete system worth of spares
[02:16:30] <jmkasunich> (except for CPUs)
[02:16:58] <jmkasunich> CPU's don't die anyway, at least not very often
[02:17:15] <jmkasunich> probably power supplies and disks are the most likely things to bite the dust
[02:17:34] <cradek> that's my experience too
[02:17:44] <cradek> with power supplies slightly worse than disks
[02:17:57] <jmkasunich> in the box with the server they were scrapping was a matching disk array - 12x18G in the hot plug carriers
[02:18:04] <jmkasunich> so tempting.....
[02:18:11] <jmkasunich> but so fscking heavy!!!
[02:18:50] <cradek> my mill's machine has those hotplug drives
[02:19:03] <cradek> it's kind of nice as I can swap in and out different OS disks
[02:19:17] <cradek> I have 4 disks I think
[02:19:38] <jmkasunich> the disks occupied the entire face of the unit (3U high?), but of course only about 7" deep... yet the box was 24" deep (and not empty)
[02:19:54] <jmkasunich> dual 500W power supplies and two huge blowers (not fans, blowers!)
[02:20:17] <jmkasunich> I bet it was at least 75 lbs
[02:20:20] <cradek> that's not going to be real quiet...
[02:20:31] <jmkasunich> yeah
[02:20:46] <jmkasunich> I wound up just grabbing 3 of the disks and leaving the rest
[02:21:07] <jmkasunich> is your hot-plug stuff HP?
[02:21:08] <cradek> I would have sure grabbed all the 18G disks
[02:21:23] <jmkasunich> I can grab the rest tomorrow if you want them
[02:21:36] <cradek> I don't think so, but there's a semi-standard plug on the disks I think
[02:21:46] <jmkasunich> the plug, yes
[02:21:48] <cradek> I'd like a couple if they're the right plug
[02:22:03] <cradek> I don't use mine as hotplug, I just turn it off and change disks
[02:22:19] <jmkasunich> the carriers tho... they slide in and latch into the cage, and there are some lite pipes that line up with power and activity lights on the backplane, etc
[02:22:21] <cradek> someday I need to make carriers/rails that fit though
[02:22:29] <cradek> right, that's exactly what I have
[02:22:42] <cradek> well I'm sure they're all different :-/
[02:22:46] <cradek> but same idea
[02:23:10] <jmkasunich> gray with a lever and a narrow blue thing you push to unlatch it?
[02:23:27] <cradek> I'm not sure, since my machine didn't come with any of them
[02:23:52] <jmkasunich> oh, you have neither carriers nor cage?
[02:24:24] <cradek> well the front of the machine has a sort of cage
[02:24:30] <cradek> in the back is those standardish connectors
[02:24:45] <jmkasunich> I see, but you don't have the carriers
[02:24:46] <cradek> but I don't have rails/carriers that work, only the blank fillers
[02:24:50] <cradek> right
[02:25:00] <cradek> so I rigged it to get it working
[02:25:15] <jmkasunich> googling for a pic of what I have
[02:25:29] <cradek> it probably wouldn't help...
[02:25:44] <cradek> I'm installing ubuntu in qemu for fun
[02:26:03] <cradek> I'm curious how long a compile will take in it
[02:27:07] <jmkasunich> http://www.econram.com/d9419a3610rp.html
[02:27:19] <jmkasunich> do your blank panels look like that?
[02:27:56] <cradek> no, but the rail on the side is believable
[02:28:15] <cradek> the blanks may be totally different from the real ones (they don't latch in)
[02:28:39] <jmkasunich> well, I'll bring disks and carriers, you can use them or just remove and use the disks
[02:28:50] <cradek> I appreciate that
[02:29:14] <jmkasunich> that pic is 34G, but still fits the LPr server... I wonder if bigger ones are on ebay
[02:29:29] <jmkasunich> since I only have 2 drives, it would be nice if they were big
[02:30:10] <cradek> you have plenty of room though, don't you?
[02:30:25] <cradek> scsi disks this big are still not common/junk
[02:30:27] <jmkasunich> http://cgi.ebay.com/Lot-of-2-HP-NetServer-LPr-5064-3541-18GB-Drive-Tray-NEW_W0QQitemZ8786622952QQcategoryZ39974QQrdZ1QQcmdZViewItem
[02:30:33] <jmkasunich> better pic of the trays
[02:31:07] <jmkasunich> I have 30G of /home
[02:31:11] <cradek> yes those might work, hard to say for sure
[02:31:20] <jmkasunich> in which I want to set up multiple virtual machines
[02:31:25] <cradek> even at 4G each, that's a lot of virtual machines
[02:31:31] <jmkasunich> I want a lot
[02:32:07] <jmkasunich> bdi-2, tng, 4.20, 4.38, ubuntu 5.10, ubuntu 6.4 when it comes out, etc, etc
[02:33:00] <jmkasunich> http://cgi.ebay.com/HP-NetServer-LPr-Dual-PIII-600-256MB-2-9-1GB-2U-Mnt_W0QQitemZ9705119896QQcategoryZ73325QQrdZ1QQcmdZViewItem
[02:33:03] <jmkasunich> thats the server
[02:33:32] <cradek> my qemu is using 150MB of ram just installing ubuntu
[02:33:41] <cradek> I hope you made enough swap
[02:33:47] <jmkasunich> 3G ;-)
[02:33:51] <cradek> perfect
[02:33:58] <cradek> you might use plenty of it
[02:34:31] <cradek> cool, that's a small machine
[02:34:46] <jmkasunich> / is 3G on sda, swap is 3G on sdb, the remaining 15G on each disk is merged into a striped LV and used for /home
[02:34:56] <steve_stallings> steve_stallings is now known as steves_logging
[02:35:04] <jmkasunich> theres one on ebay with dual 800MHz cpus and 1G ram.....
[02:35:28] <cradek> that would even make a nice desktop
[02:35:38] <jmkasunich> need a deep desk
[02:35:49] <jmkasunich> they're not tall, but they are deep
[02:35:50] <cradek> well I'd put it next to the desk
[02:35:54] <cradek> you know what I mean
[02:36:19] <jmkasunich> you mean a box to use instead of a server
[02:36:33] <cradek> yeah
[02:36:51] <cradek> so now that you're back, what should we do next with emc?
[02:37:00] <jmkasunich> release it?
[02:37:11] <cradek> yeah, but that's boring
[02:37:31] <jmkasunich> I won't feel free to do non-boring things until the release is done
[02:37:46] <jmkasunich> and several other things are done, like the new farm working, etc
[02:37:47] <cradek> I wanted to make the TESTING packages tonight, but there's no cvs
[02:38:04] <cradek> I think that's the next step toward a release
[02:38:10] <jmkasunich> yeah
[02:38:29] <jmkasunich> I should get the new farm out, put the new ram in it, and start setting things up
[02:39:06] <jmkasunich> actually, before I do that and before jepler goes away, I should put that new make on slot 2 and see if it builds
[02:39:55] <cradek> I still think that borders on silly, but I don't object
[02:46:24] <cradek> hello
[02:46:57] <skunkworks> hello?
[02:47:04] <cradek> hello?
[02:47:17] <jepler> hello?
[02:47:17] <skunkworks> how is threading?
[02:47:24] <jepler> skunkworks: did you see the last set of photos?
[02:47:29] <cradek> did you see the latest email/photos?
[02:47:43] <skunkworks> did you post them here?
[02:47:48] <skunkworks> I will look.
[02:51:59] <cradek> I can paste the URLs if you don't have the mail, I didn't mean to be difficult
[02:52:00] <skunkworks> very nice. Great work
[02:52:07] <cradek> thanks
[02:52:28] <skunkworks> Just looked back at logger_aj
[02:52:43] <cradek> aren't you on the emc-devel list?
[02:53:09] <skunkworks> I can look on sourceforge - but usually there is a delay.
[02:53:17] <skunkworks> no just the user list
[02:53:18] <cradek> ah
[02:53:30] <cradek> I didn't cc -users, maybe I should have
[03:00:52] <jmkasunich> if you cc users, make a BIG note that its still experimental
[03:02:30] <fenn> * fenn is a fan of "release early, release often"
[03:03:04] <fenn> * fenn is also a fan of cutting parts out of air first
[03:04:16] <jmkasunich> threaded air isn't nearly as impressive
[03:04:37] <skunkworks> skunkworks has changed the topic to: you
[03:04:37] <ChanServ> ChanServ has changed the topic to: "Welcome to the Enhanced Machine Control forum - Support and development of a linux based CNC control. | Home: linuxcnc.org | Regular Developers' meetings Sundays 14:00-18:00 GMT | wiki up @ http://wiki.linuxcnc.org | EMC usage map: http://www.frappr.com/emctheenhancedmachinecontroller
[03:05:00] <skunkworks> woops - what did I just do?
[03:05:02] <jepler> cradek: in g33, the k- value gives the distance XYZ moves per spindle revolution?
[03:05:08] <jepler> skunkworks: nothing that ChanServ didn't correct
[03:05:12] <skunkworks> ok
[03:06:38] <cradek> jepler: currently, yes
[03:06:51] <cradek> jepler: some systems use F for that, which seems more appropriate to me
[03:07:01] <cradek> (since you can move in any direction)
[03:08:07] <jmkasunich> that thought has crossed my mind too
[03:08:13] <fenn> jmkasunich: ever seen a hilsch vortex tube?
[03:08:26] <jmkasunich> are those the ones with a Maxwell's demon trapped inside?
[03:08:27] <fenn> or a plasma cutter
[03:08:32] <fenn> yeah
[03:08:38] <cradek> in fact, if I had cvs, maybe I'd go ahead and change that
[03:09:00] <skunkworks> cvs down again?
[03:09:05] <cradek> all day
[03:09:07] <jepler> skunkworks: yeah, developer cvs is busted
[03:09:10] <jmkasunich> made one a long time ago, it worked, but not well (I was in my teens and had very limited metalworking skills/equipment)
[03:09:18] <jepler> hm it's taking a long time to save this wiki page
[03:10:46] <jepler> there, it finally saved
[03:10:52] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?SpindleSynchronizedMotion
[03:10:56] <jepler> maybe I should make the image a bit smaller
[03:15:28] <jepler> is the lathe code in the recent TESTING?
[03:15:57] <skunkworks> ok time for bed. Good work.
[03:16:01] <jepler> see you skunkworks
[03:16:20] <skunkworks> friday finaly :)
[03:19:52] <cradek> jepler: yes, the code was already working a while ago - I haven't changed it recently
[03:20:05] <jepler> I've noted that on the wiki page too
[03:21:31] <cradek> cool, thanks for doing that
[03:22:08] <fenn> i like how the maxnc makes a pretty blue splotch in the background
[03:22:11] <jmkasunich> hmm, the mitsu version of G33 has a shaft angle, that would make multi-start easy
[03:22:41] <cradek> I'm surprised by how good that photo turned out, I usually suck at that
[03:23:29] <cradek> jmkasunich: another spec I read said for multi-start, you have to figure out the Z offset yourself
[03:23:46] <cradek> not like it's hard - you just offset one F/K value in Z
[03:24:02] <cradek> err half of one, I guess
[03:24:05] <cradek> something like that
[03:33:51] <fenn> lead/N
[03:34:37] <cradek> yeah that
[03:34:38] <fenn> there might possibly be a case where you couldnt do that
[03:34:47] <fenn> like a three jaw chuck for example
[03:35:04] <cradek> well you could start from the outside?
[03:35:06] <fenn> but that's academic at this point
[03:35:13] <cradek> but yeah I agree in general there might be trouble cases
[03:35:47] <cradek> it would be easy to add offset, except canon would have to change again.
[03:39:01] <jepler> that's more a problem for axis than for emc
[03:39:19] <cradek> yeah, it's just a minor problem.
[03:40:11] <fenn> what do you guys think about displaying other info on the axis backplot, like r/p/w rotation
[03:40:26] <fenn> or does the cone already do that?
[03:40:30] <jepler> fenn: I'm not opposed to it
[03:40:39] <fenn> or M codes
[03:40:59] <jepler> what M codes do you mean?
[03:41:07] <jepler> M1xx codes are shown with a dwell-like signal
[03:41:11] <jepler> er, symbol
[03:41:12] <fenn> all of them i guess
[03:41:20] <cradek> for a lathe, having the Z axis always be up is awkward... we may have to add some flexibility.
[03:47:47] <jepler> you guys with this neat hardware need to code it
[03:47:58] <jepler> for now you're lucky you have 3 dimensions in axis
[03:49:09] <cradek> bah
[03:49:38] <cradek> my sideways lathe is particularly bad - when the cone goes up, the "tool" goes down
[03:50:27] <jepler> night folks
[03:50:32] <cradek> night
[03:50:37] <jmkasunich> goodnight
[03:51:10] <jmkasunich> cradek: you need to turn the cone into a cylinder
[03:52:16] <cradek> jmkasunich: if we somehow had the tool shape, a lathe is so simple that it might be possible to model the work somewhat...
[03:52:32] <cradek> but that's a project for another day
[03:54:01] <jmkasunich> having the tool shape is also needed for lathe tool offsets
[03:54:50] <cradek> offsets are where I start having no clue what to do
[03:55:27] <cradek> (and I have little interest in anything that would make me work in the interp)
[03:55:42] <jmkasunich> dito
[03:55:44] <jmkasunich> ditto
[03:56:08] <cradek> if(code IS_IN interp) work_on_it SET_TO dont_wanna;
[03:56:22] <jmkasunich> you mentioned in your post to the list that we might want to improve the HAL interface to the encoder
[03:56:28] <jmkasunich> I agree, that inverter needs to go away
[03:56:53] <jmkasunich> if I wasn't up to my elbows in this server I'd talk about it now
[03:56:58] <cradek> I don't even understand its purpose
[03:57:02] <cradek> we can do it anytime
[03:57:14] <cradek> also there's the rpm issue still to be fixed
[03:57:32] <jmkasunich> this chassis is actually pretty nice, you can remove/replace the mobo almost easily
[03:57:58] <jmkasunich> as long as you don't trap that skinny little wire harness in the edge card connector and cut it in half, like I did
[03:58:08] <cradek> ouch
[03:58:26] <jmkasunich> fortunately I have a spare of the harness too
[03:58:36] <cradek> not anymore you don't
[03:58:40] <jmkasunich> (only two wires, carries power to a SCSI repeater board)
[03:58:57] <jmkasunich> I could repair with solder and heatshrink if needed
[03:59:21] <jmkasunich> (I'll have another spare tomorrow... the third server is still in the dumpster ;-)
[03:59:28] <jmkasunich> (and another spare mobo too)
[03:59:48] <cradek> another dual 800? that's still a nice machine
[04:00:05] <jmkasunich> no
[04:00:19] <jmkasunich> I had a dual 600 and single 400
[04:00:26] <jmkasunich> and the one in the dumpster is a single 500
[04:00:31] <jmkasunich> all have 2 CPU slots
[04:00:53] <jmkasunich> you have to add the CPU and a power supply module (switching regulator for the CPU core voltage)
[04:01:35] <jmkasunich> the dual 800 was the one on ebay
[04:01:45] <cradek> single 500 is bordering on not-worth-picking-up unless it's a complete machine
[04:02:57] <jmkasunich> its a parts machine to keep this one working
[04:03:03] <jmkasunich> I won't haul the whole thing home
[04:03:10] <jmkasunich> * jmkasunich is not happy
[04:03:26] <jmkasunich> after the mobo switch, I get blinking lights on the mobo
[04:03:30] <fenn> too many toys, not enough time
[04:03:45] <jmkasunich> (4 lights, one per DIMM slot, that light up when a dimm is installed and happy)
[04:03:57] <jmkasunich> now they're blinking, 2 on and 2 off, alternating
[04:04:18] <jmkasunich> and I have no magic decoder ring
[04:04:22] <fenn> you need to re-fluster the transcombobulator
[04:05:12] <fenn> http://video.google.com/videoplay?docid=5125780462773187994&q=retro+encabulator
[04:05:23] <jmkasunich> me thinks I need to change back to the original mobo, and hope it still works
[04:05:33] <fenn> oh you dont have sound
[04:09:49] <jmkasunich> * jmkasunich holds breath, flips switch
[04:10:19] <jmkasunich> pheww.... lights look OK
[04:12:18] <jmkasunich> duh.. the 2nd board is only labeled for up to 550MHz, not 600
[04:12:28] <jmkasunich> even tho both are otherwise identical
[04:12:52] <jmkasunich> (the 600MHz one has a sticker over the silkscreened markings, with the additional dip switch settings for 600MHz)
[04:13:26] <jmkasunich> of course, I notice this _after_ I've already swapped back to the other one
[06:21:55] <anonimasu> morning
[06:22:52] <Jymmm> morin anonimasu
[06:24:05] <anonimasu> did you see the videos of that lathe I posted last night?

[08:27:28] <anonimasu> iab :)
[08:27:44] <anonimasu> trying to get a nwe lib for the plc..
[08:27:47] <anonimasu> from the manufacturer..
[08:28:39] <anonimasu> hm
[08:28:42] <anonimasu> I think the net just died
[08:29:04] <anonimasu> or well a bit
[08:29:38] <Jymmm> it dies, I broke the string
[08:30:33] <anonimasu> hehe
[08:37:05] <anonimasu> * anonimasu sighs
[08:37:36] <Jymmm> ?
[08:39:19] <anonimasu> what a mess
[08:40:08] <anonimasu> my connection is dead..
[08:41:23] <anonimasu> works now
[08:41:51] <anonimasu> did you notice they run dry in the tsugamai videos
[08:42:16] <Jymmm> Yeah, but just for recording the videos, I saw coolant leaking a bit.
[08:42:27] <anonimasu> yeah
[08:42:32] <anonimasu> true, still impressive
[08:42:43] <anonimasu> I pasted a video of a machine where they forgot coolant..
[08:42:52] <anonimasu> it kind of went frrp and the tooling died :)
[08:42:57] <Jymmm> lol
[08:43:17] <Jymmm> primary reason why I dont do metal

[08:44:28] <anonimasu> heh..
[08:47:27] <Jymmm> damn! lol
[08:47:47] <anonimasu> I crave for a cnc lathe D:
[08:47:48] <anonimasu> :D
[08:48:02] <anonimasu> I love the videos of turning the chess piece in brass...
[08:48:06] <anonimasu> on the centroid page

[18:00:25] <tfmacz> jepler, you there???
[18:09:54] <K4ts> hello
[19:09:41] <jepler> tfmacz: I'm back now
[19:14:49] <anonimasu> hm
[19:15:01] <anonimasu> have anyone of you guys got a clue about making silicone molds?
[19:16:19] <jepler> not me
[19:16:49] <rayh> I make mould in the kitchen occasionally.
[19:16:51] <anonimasu> hm..
[19:17:02] <anonimasu> hm.. crap :/
[19:17:15] <anonimasu> I've got a nice little part for my bookhelve I'd like to cast..
[19:17:20] <anonimasu> I've got epoxy and stuff somewhere..
[19:17:27] <anonimasu> need it to get more shelves up
[19:22:27] <anonimasu> I wonder if I have some RTV at home
[19:24:19] <Jymmm> anonimasu dont forget the mold release
[19:29:58] <anonimasu> Jymmm: rtv dosent adhere to other stuff then itself
[19:36:08] <Jymmm> ROTFLMAO.... wanna bet?
[19:36:32] <anonimasu> atleast not the moldmaking stuff..
[19:36:43] <Jymmm> I use RTV to adhere everything to everything
[19:36:56] <anonimasu> hm..
[19:37:06] <anonimasu> I'll machine a mold of something tomorrow..
[19:38:14] <Jymmm> anonimasu: Well... poor man's mold release for silicon: vaseline and acetone, about 1:2 to 1:3 ratio
[19:38:40] <Jymmm> acetone, xylene, or whatever you have on hand.
[19:39:00] <anonimasu> I can make a 2 part mold with some work.. :)
[19:39:02] <anonimasu> no big deal..
[19:39:26] <anonimasu> or I can find other parts..
[19:39:35] <anonimasu> parts/other thingies like what I need
[19:40:01] <Jymmm> http://www.google.com/search?q=rtv+mold+release&sa=Search+Google
[19:40:22] <anonimasu> I have real mold release for fibreglass..
[19:40:45] <Jymmm> I'm not sure it's the same, but couldn't hurt.
[19:40:54] <anonimasu> oh, for the final mold..
[19:41:11] <anonimasu> making theese things out of epoxy..
[19:41:24] <anonimasu> or whatever you call it..
[19:41:45] <Jymmm> ok, cool. just wanted to to remind you is all.
[19:41:51] <anonimasu> yeah :)
[19:41:56] <anonimasu> if I had some rtv i'd use it but I dont
[19:42:17] <anonimasu> very easy part to create
[19:42:25] <anonimasu> if I even bother
[19:46:54] <K4ts> hello
[19:48:05] <jepler> CNC graffiti? http://www.makezine.com/blog/archive/2006/03/hektor_the_spray_painting_robo.html
[19:57:58] <jepler> "
[19:57:59] <jepler> Through the use of Scriptographer, Hektor is controlled directly from within Adobe Illustrator,"
[19:58:04] <jepler> blah!
[19:58:25] <cradek> surely he meant truetype-tracer and emc
[19:59:20] <alex_joni> hiya
[20:00:21] <cradek> jepler: it has a lot of unnecessary movement
[20:01:36] <jepler> Yeah, I'm looking at "beautiful place" and I'm included to agree
[20:01:50] <jepler> it also must not be all that fast
[20:02:17] <cradek> no, seems really slow
[20:02:22] <cradek> I wonder what all the extra motion is about
[20:02:56] <jepler> does it always start from the same direction?
[20:04:45] <alex_joni> jepler: that's an older project, I remember seeing it while I was documenting for my tripod
[20:05:11] <cradek> alex_joni: do you understand why it has all the extra motion?
[20:05:39] <alex_joni> * alex_joni can't find the movie
[20:05:53] <jepler> it enters tangent to the curve it's drawing
[20:06:04] <jepler> and it has to stop and re-enter when an edge is too sharp
[20:06:20] <jepler> it must have really low accel, you get an idea what it is from seeing the size of the circles
[20:06:47] <cradek> oh, maybe that's to keep it from swinging around (flexing the cables)
[20:07:13] <alex_joni> yup, it's not such a big weight
[20:07:25] <alex_joni> and even with weight to keep them streched, you'd have inertia
[20:07:51] <cradek> it's still a very neat hack
[20:08:02] <alex_joni> http://video.google.com/videoplay?docid=-283528724322180681&pl=true
[20:08:08] <alex_joni> that's an improved version ;)
[20:08:13] <alex_joni> not very portable though
[20:08:19] <cradek> in Graffiti-Alphabet you can see the homing
[20:18:10] <alex_joni> cradek: Beautifull place shows lots of insight stuff
[20:18:21] <alex_joni> homing too, and also why it needs those extra motions
[20:18:29] <alex_joni> I think it always wants to stay at speed
[20:18:48] <alex_joni> so it plans those circular G0's to keep the speed as constant as possible
[20:20:29] <fenn> havent watched the movies but a lot of HSM cam software does this
[20:20:42] <fenn> litle loopies after every corner
[20:20:54] <alex_joni> fenn: this is small speed ;) but very shaky
[20:21:10] <alex_joni> so I think this minimizes wobbling & such
[20:22:03] <anonimasu> yeah
[20:22:20] <anonimasu> that should place less wear on the machine aswell
[20:22:34] <anonimasu> wear/stress
[20:22:56] <anonimasu> as you dont have to suddenly accelerate x kg of table/turret to 1g to make it..
[20:25:11] <anonimasu> crap.. I overfilled my bathtub almost
[20:26:26] <alex_joni> * alex_joni passes anonimasu one of those inflating boats

[20:39:03] <alex_joni> just bought it
[20:39:04] <alex_joni> :)
[20:39:36] <alex_joni> was out shopping some food, and I thought I'd buy it
[20:40:23] <fenn> what do the litle mini dials do?
[20:40:37] <anonimasu> very neat clock
[20:40:37] <anonimasu> :)
[20:40:38] <alex_joni> fenn: it's a cronograph
[20:41:03] <alex_joni> the one at 6 o' clock counts the seconds (normal time)
[20:41:15] <fenn> ah so you press a button and they measure the time elapsed
[20:41:32] <alex_joni> the top-left measures minutes, top right measures 1/20th seconds
[20:41:48] <fenn> that's not SI :P
[20:42:22] <alex_joni> SI?
