16:14:59 <rayh> Sat am.  Roland is finishing the parts for spindle encoder.
16:15:35 <rayh> Soon we will be able to assemble the drawbar and run hydraulics.
16:16:23 <rayh> This mornings task is to tickle the solenoids and read proxes.
16:16:40 <jmkasunich> and run the spindle motor

16:34:26 <alex_joni> how's it going people?
16:34:46 <jmkasunich> just getting started again
16:35:06 <alex_joni> coo.. heard it's starting to look like smthg
16:35:11 <jmkasunich> progress to date: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?MazakLog
16:36:39 <alex_joni> sweet
16:37:06 <jmkasunich> I've been pestering Ray to add to the writeup, I don't recall everything he did
16:37:58 <alex_joni> heh.. nice
16:38:07 <alex_joni> ok.. gotta go (only briefly checked my mail)
16:38:13 <alex_joni> will be back in 2-3 hours or so
16:38:21 <alex_joni> want to do some coding today..
16:38:50 <alex_joni> any more thoughts on the indexing stuff? or shall we take care of it at a later stage?
16:39:02 <alex_joni> * alex_joni really wants to finish the STG driver this weekend
16:39:59 <jmkasunich> we were talking about it a little at breakfast, but still no real solution
16:40:19 <alex_joni> ok.. been looking at the motenc driver
16:40:30 <alex_joni> seems that it's done a bit strange for my taste
16:40:38 <jmkasunich> one possibility - let the encoder driver reset the position, and have the motion controller turn off pid enable for one servo period when that happens, to avoid the disturbance
16:40:47 <alex_joni> but I like the idea of a single bidirectional wire between motion and driver
16:41:05 <alex_joni> one direction (set high) we are homing
16:41:14 <alex_joni> other direction (pulled low) we found index pulse
16:41:49 <alex_joni> I like the other possibility (get another position feedback for the stored index-position)
16:41:57 <jmkasunich> I'd rather have 2 wires (not particularly fond of bidirectional signals, even tho HAL supports them)
16:42:13 <alex_joni> in this case the motion controller can decide when it likes to update the position
16:42:53 <jmkasunich> need to think on it some more
16:43:27 <alex_joni> ok.. we'll talk about it later
16:43:34 <alex_joni> * alex_joni really needs to go away
16:43:45 <alex_joni> btw, I closed some trackers today, hope you're fine with it
16:44:36 <alex_joni> later..
16:44:49 <alex_joni> wish you best on the mazak

19:21:42 <jmkasunich> encoder parts are done, ray is re-assemblng right now
20:23:32 <rayh> Head assembly is back together.  Connecting encoder now.
20:23:55 <rayh> Jmk is working the pc end of the encoder connections.
20:24:38 <rayh> The axis tuning using torque mode is interesting to say the least.
20:24:52 <rayh> The halscope helps a lot.
20:32:11 <rayh> rayh has changed the topic to: "Mazak EMC retrofit.  X and Y homing and moving nicely.  Working on Z and spindle now."
