how is the mini-bridgport-update-fest going?
we retrofitted the bridgeport yesterday
and everything else we did worked too - it was a great success
Holy crap - that was fast!

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)
this morning we did some more careful amp and pid tuning
seb left about 3pm.
we figure it's got to be a record. everything went right.
oh cool, you got it extended! neat!
is that a spline in the female end?
How is the tuning with the ncxxx amps?
the encoders are only .0001 resolution. during cutting speeds we have about .0003 following, during rapids maybe .0012
is seb taking it off your hands?
I'm thrilled an emc person is getting it
you had that machine for what, two years, and it only took 11 hours to retrofit it?
don't you feel silly spending ?? hours trying to figure out how to fix that membrane keyboard?
so did you actually use that heavy-ass transformer I sent you a while ago?
yes we will use it - it's not on yet, but he's going to do the single phase conversion.
we had hoped to get to it, but not enough time.
oh, you have a rotary there, right?
yes a big one
kinda bummed I missed it
it ran both machines pretty much all weekend!
yeah it would have been nice if you could have come.
the time sure went fast though
we (mostly stuart) made a BT40 holder for my probe, so it can go in the tool changer now
that's really nice
also we (mostly stuart) made an adapter for replacing the spindle speed change air motor
so he won't need air OR 3 phase which is a very big improvement
cradek: did stuart finish the adapter?
jepler: we finished the machine end before he left, but not the motor end
we don't know the length of the shaft on the motor he wants to use
we can finish it here when he comes back, or he could take the half-finished piece and do it when he's ready
Wow - sounds like you guys had fun!
not sure if jepler had fun, but he was here a lot :-)

cradek: very nice
so when do we want the v2.4_branch? today? in a week?
EMC: 03jthornton 07master * r92d99f07aa18 10/docs/man/man1/halui.1: number of joints depends on the config
maybe announce the feature freeze today
ok, I'm done... I think :)
and wait a bit before the branching
jthornton: even afterwards, cherrypicking will work
and merging, if you start your work from the branch point of 2.4 and master
Did you have a good weekend?
jepler: no itch to get larger equipment?
skunkworks_: just an itch to impose on cradek more often
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2010-02-01.txt
Can I run emc with two synced spindles somehow?
(lathe with two spindles)
maybe you can use the encoder_ratio component somehow
I can try
micges: how do you want them synched?
to get material from one to another and start machining from another side
are they driven in position mode?
there is precise positioning for drilling so it seems so
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
