I'm still having this problem where in every production program, at some point the turret will hang up after unclamping. I've trouble shot far enough to know that all the signals are correct for the unclamped state. The buffer displays MEM-STRT-MTN-FIN. To me that says the turret servo has been told to rotate but it's not rotating. One question I have is where do I find verification for the signal?. Is that going to be a G address? What would it be called? I have been unable to locate anything in the ladder or electrical manuals that says Turret Motor Forward or what have you. The ladder for the turret is about 15 pages long so it's a mind bender, especially for someone who barely gets ladders anyway. BTW I have also physically verified the turret unlock pin is out and the Y address agrees. X and Y diagnostic bits I get.
But wait, here's the wrench.
I can rotate the turret without failing even once in a multitude of different circumstances. I've created programs run from memory like any other program that rotates the turret to and fro, even with just the two tools this current job has. I've done multiple version of it too, including axis movement at rapid between turret changes. Coolant on and off between changes. I've taken the failing program and tried changing to an unused station first in both CW and CCW directions before going back to the tool I really want. It then hangs on the new unneeded tool station. Every scenario I can come up with to mimic the current program short of just running the failing program. Manual operation also never ever fails.
It's seems like under certain circumstance the turret drive call is different or coming from a different place that somehow makes a difference in success or failure. I have a long production run coming up next and really want to get this figured out.
Don't know where to look or what to do next. All answers and ideas are much appreciated.

On a similar note.In the PMC or Ladder screen I see two soft buttons. DUMP and DPARA. Can these help me offload a copy of the ladder or something? I have a ladder book for a roughly similar machine but not the exact one. So far it seems pretty close. Any idea what these buttons do? Mori wants $650.00 and 6 weeks for a copy of the ladder. I might have to bight the bullet someday, but... Thanks for any and all help.
