Butting in here, not sure Andy. It seems to me the ideal situation would be to just shut the spindle down, while NOT unlocking the axis that was slaved to it, which might save the tap AND allow hand applied power in reverse to unscrew the tap from the hole with the machine still following the tap back out of the hole. The chances of restarting the operation to finish that hole are somewhere between slim and .00001% unless the starting point is saved and can be run back to, which I don't believe is the case now as its forgotten at the end of each run with the current code anyway, but the tap may be saved. Perhaps this starting point save might be part of this GSOC G33.1 improvement project? Back to my testing, I slowed Z down, both for velocity and accel again as I was watching it, and it appeared that the fastest move it was making was at the upper end of the cycle as it reset the height back to the original starting point. That looked like an ideal place for it to lose a step, so I turned both maxvel and accel's down about 20%, which seemed to slow that position reset at the end of the g33.1. In backgear low, the motor is pretty well tapped out at 1250 revs so I let it run at that speed for about 15 minutes which it did w/o any problems. I received some ER20 collets from China today, but the package labeled as haveing 10 ea 1/8" collets in it, had 10 collets in it, but they were all 3/8' and I already had several of those that I've little or no use for since I don't own 15 ea 3/8 drill bits. :) Anybody need any 3/8" ER20's? :) I assume a language barrier. I'll check on ebay & see if I can get it fixed. Or just re-order perhaps as I do need another handfull of 1/8" collets in any event.
