[22:12:32] <jepler> alex_joni: thanks
[22:12:51] <alex_joni> I can hmmm all day long if it helps
[22:13:52] <jepler> I meant for restarting the logger
[22:15:27] <alex_joni> ah, don't sweat it.. I do that all the time ;)
[22:28:14] <jepler> hm, the package's "touchy" config doesn't work
[22:28:17] <jepler> something about nml files
[22:29:37] <jepler> oh, touchy's not installed; the message was misleading
[22:31:32] <cradek> doh
[22:35:49] <jepler> cradek: I'll work on it
[22:36:16] <jt-plasma> cradek: what kind of drives do you have on your Hardinge?
[22:45:16] <cradek> jt-plasma: the original velocity amps
[22:45:33] <cradek> they are GE mumblemumble
[22:45:35] <cradek> ancient
[22:45:55] <jt-plasma> this one has semens for the X and Z axis and Fanuc for the spindle
[22:46:21] <jt-plasma> this one is mid 80's
[22:46:42] <jt-plasma> it does have encoders for everything
[22:53:15] <cradek> that's great!
[22:53:35] <cradek> the spindle on mine was just an ac motor hooked to the line (varispeed)
[22:54:06] <cradek> is it velocity mode dc servos?
[22:54:25] <jt-plasma> LOL, I don't have a clue ATM
[22:54:36] <jt-plasma> 380v
[22:54:44] <cradek> woo
[22:54:49] <cradek> that's a lotta v
[22:56:05] <jt-plasma> there is a 3-phase step up transformer for that in the cabinet
[22:56:12] <jt-plasma> the spindle is 200-220v
[22:56:25] <cradek> step up for the servo dc bus? wow
[22:56:31] <jt-plasma> yea
[22:57:56] <alex_joni> 400v is quite common over here
[22:58:13] <alex_joni> the servo's we use take 400V rectified (565V DC)
[23:00:06] <jt-plasma> the servo drive has very few wires connected to it each axis has one cable with three wires and one cable with 2 wires and one single cable
[23:00:17] <jt-plasma> besides the power type wires
[23:00:26] <cradek> huh
[23:00:43] <cradek> hard to guess from that...
[23:00:56] <alex_joni> maybe resolver?
[23:01:05] <jt-plasma> yea, I'm trying to assimilate the drawings now
[23:01:10] <alex_joni> cable with 3 wires could be sin/cos/gnd
[23:01:11] <cradek> not enough wires for a resolver
[23:01:12] <jt-plasma> all encoders
[23:01:29] <cradek> resolvers would have three twisted pairs, probably plus ground
[23:01:39] <jt-plasma> at least the docs say so all Hiedihien or however you spell it
[23:01:41] <alex_joni> hmm.. so would encoder
[23:01:46] <alex_joni> heidenhein
[23:01:53] <jt-plasma> yea that one :)
[23:02:02] <cradek> 2 wires = tach
[23:02:09] <alex_joni> sorry.. heidenhain
[23:02:32] <jt-plasma> the servo maintence drawing starts with PWM Servo with P.C.B. D & E
[23:03:33] <jepler> $ git diff --stat origin/master | tail -1

[23:03:33] <jepler> 15
[23:03:41] <jepler> it can't possibly be hasty to push this without review
[23:03:57] <cradek> noooo
[23:03:57] <jepler> it's such a tiny change, what could go wrong?
[23:04:28] <alex_joni> at least it's master not v2_3
[23:05:03] <cradek> what is it? if it's right, push it...
[23:05:05] <cradek> if it's wrongheaded, don't
[23:05:31] <alex_joni> is it hostmot2 stuff?
[23:05:36] <jepler> right or wrongheaded? are those the only two choices?
[23:05:40] <jepler> it's packaging stuff
[23:06:08] <jepler> I'll at least try it on an 8.04/rt system before I push. but if anyone else wants to try it: git checkout -b packaging origin/master; git pull git://git.unpythonic.net/emc2-jepler.git packaging
[23:06:17] <jepler> bbl
[23:07:58] <jt-plasma> the turret has an encoder too
[23:19:47] <jt-plasma> the encoders go back to the controller :) I finally found those cables
[23:32:08] <jt-plasma> I found the spindle motor and the spindle brake :)
[23:42:33] <jt-plasma> the spindle gets a vel cmd, now to figure out what kind :/
