I'm still having issues with the rigid tapping. It works sometimes and fails other times. After scoping the motion.spindle-revs, it appears to be consistent with what we would expect aside from one possible issue. The spindle revs reset to zero upon G33.1 being called, then count up until they stop, reverse, go negative past zero, then return to clockwise motion. However, on the second zero crossing (going positive) the revs go positive, only to be reset to zero momentarily thereafter. I'm not sure if this is normal behavior or not.
However, what isn't normal behavior is that the ppmc.0.encoder.03.index value is loaded with noise. Not occasional noise, but constantly triggering in irregular intervals regardless of whether the spindle is turning. I'm baffled as to how this could be so noisy and was wondering where you might look next. Grounds look fine aside from the fact that the control cabinet and the power cabinet have a ground wire connecting them in addition to being grounded through the machine. When removed from the USC board, the index can be measured with a multimeter as the spindle is rotated. I forgot to bring my scope to the shop today (I didn't think I'd need it) so I can't scope anything until tomorrow. Is it possible there's a pull-up resistor missing?
