[01:21:51] <skunkworks> how is the mini-bridgport-update-fest going?
[01:34:07] <cradek> it's over!
[01:34:28] <cradek> we retrofitted the bridgeport yesterday
[01:34:55] <cradek> and everything else we did worked too - it was a great success
[01:36:02] <skunkworks> Holy crap - that was fast!
[01:36:16] <cradek> yep
[01:37:10] <skunkworks> did you see? http://www.electronicsam.com/images/KandT/conversion/xaxis/xaxisshaft.JPG

[01:37:53] <cradek> decision to start was 1:30pm yesterday, machine was running emc, homed to index, estop chain done, limits set, spindle working, basic tuning, and first chips made by 12:45 am (11h15m start to finish)
[01:38:18] <cradek> this morning we did some more careful amp and pid tuning
[01:38:40] <cradek> seb left about 3pm.
[01:38:58] <cradek> we figure it's got to be a record. everything went right.
[01:40:25] <cradek> oh cool, you got it extended! neat!
[01:40:35] <cradek> is that a spline in the female end?
[01:46:51] <skunkworks> yes
[01:47:25] <skunkworks> How is the tuning with the ncxxx amps?
[01:48:50] <cradek> the encoders are only .0001 resolution. during cutting speeds we have about .0003 following, during rapids maybe .0012
[01:49:05] <skunkworks> nice!
[01:49:14] <skunkworks> is seb taking it off your hands?
[01:49:18] <cradek> yep
[01:49:29] <cradek> I'm thrilled an emc person is getting it
[01:50:19] <jmkasunich> holy crap
[01:50:37] <jmkasunich> you had that machine for what, two years, and it only took 11 hours to retrofit it?
[01:50:59] <jmkasunich> don't you feel silly spending ?? hours trying to figure out how to fix that membrane keyboard?
[01:51:00] <cradek> no, 11:15
[01:51:05] <cradek> :-)
[01:51:29] <jmkasunich> so did you actually use that heavy-ass transformer I sent you a while ago?
[01:51:55] <cradek> yes we will use it - it's not on yet, but he's going to do the single phase conversion.
[01:52:13] <cradek> we had hoped to get to it, but not enough time.
[01:52:14] <jmkasunich> oh, you have a rotary there, right?
[01:52:19] <cradek> yes a big one
[01:52:32] <jmkasunich> kinda bummed I missed it
[01:52:33] <cradek> it ran both machines pretty much all weekend!
[01:52:44] <cradek> yeah it would have been nice if you could have come.
[01:52:52] <cradek> the time sure went fast though
[01:53:17] <cradek> we (mostly stuart) made a BT40 holder for my probe, so it can go in the tool changer now
[01:53:30] <cradek> that's really nice
[01:54:42] <cradek> also we (mostly stuart) made an adapter for replacing the spindle speed change air motor
[01:55:11] <cradek> so he won't need air OR 3 phase which is a very big improvement
[01:56:45] <jepler> cradek: did stuart finish the adapter?
[01:57:10] <cradek> jepler: we finished the machine end before he left, but not the motor end
[01:57:27] <cradek> we don't know the length of the shaft on the motor he wants to use
[01:57:55] <cradek> we can finish it here when he comes back, or he could take the half-finished piece and do it when he's ready
[02:01:08] <skunkworks> Wow - sounds like you guys had fun!
[02:03:51] <cradek> yep
[02:04:03] <cradek> not sure if jepler had fun, but he was here a lot :-)

[10:18:52] <alex_joni> skunkworks: cool
[10:18:54] <alex_joni> cradek: very nice
[12:53:59] <jepler> so when do we want the v2.4_branch? today? in a week?
[13:03:21] <CIA-81> EMC: 03jthornton 07master * r92d99f07aa18 10/docs/man/man1/halui.1: number of joints depends on the config
[13:07:01] <alex_joni> maybe announce the feature freeze today
[13:07:04] <jthornton> ok, I'm done... I think :)
[13:07:06] <alex_joni> and wait a bit before the branching
[13:07:16] <alex_joni> jthornton: even afterwards, cherrypicking will work
[13:25:57] <jepler> and merging, if you start your work from the branch point of 2.4 and master
[14:41:04] <jepler> hi skunkworks_
[14:41:18] <skunkworks_> Good morning
[14:41:29] <skunkworks_> Did you have a good weekend?
[14:42:19] <jepler> yep
[14:44:45] <skunkworks_> jepler: no itch to get larger equipment?
[14:45:24] <jepler> skunkworks_: just an itch to impose on cradek more often
[14:47:34] <skunkworks_> heh
[15:51:18] <skunkworks_> logger_dev: bookmark
[15:51:18] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2010-02-01.txt
[18:58:57] <micges> hi all
[18:59:52] <micges> Can I run emc with two synced spindles somehow?
[19:00:05] <micges> (lathe with two spindles)
[19:08:02] <cradek> maybe you can use the encoder_ratio component somehow
[19:21:24] <micges> I can try
[21:33:44] <alex_joni> micges: how do you want them synched?
[21:52:40] <micges> to get material from one to another and start machining from another side
[21:54:45] <alex_joni> are they driven in position mode?
[21:58:11] <micges> don't know
[21:58:48] <micges> there is precise positioning for drilling so it seems so
[22:22:55] <robh_> most modern lathes i seen with two spindles the two drives talk to each other and sync each other (one master, other slave) before coming together to pickup part, once part is parted off, the two spindles go back into "single" mode
