I will also check the Distance to Go - that is a good thought. I have run with diagnostics on, and there are no clues there. It just shows the "GO" statement and nothing after the motion stops.
I do plan on doing some servo tuning this weekend using the WSDK software.
I'm still not sure I am following the explanation. While the machine is running the part, burning at about .1 IPM, it just stops. Not at a program step, but anywhere in the middle of the programmed motion. At this point, the motion command voltage is near zero, wheras while it was running it was fluctuating around .3 volts. I see this as the control telling the machine to stop. Is this not correct?
Now while I am still at this point with the machine not moving, but in the middle of my program, I lean on the table IN THE DIRECTION of the cut. Not only does the motion does not start again, but the controller motion voltage signal increases to RESIST the motion.
It seems to me that if it were a servo tuning issue, nudging the table in the direction of the cut would make cutting resume (as someone earlier suggested) instead of this motion being resisted to keep the current location. |
