I basically have two problems, one more serious than the other.

The serious problem is the Z axis has quit moving/jogging . . . it makes the stepper noise like it's trying but it doesn't move.

I had this problem before and I think I remember replacing some transistors???? We stepped the motor and were checking for voltages going low/high to the stepper motor. I don't remember where this was and I'll finally have some time to look at it again.

The second less serious problem is at high feed rates the Y axis seems to have problems. Of course according to Murphy's law, it seemed to happen only when a part was loaded . . . not when running without a part. I slowed the RPM and feed rate down and that got me through the couple of parts I needed to get done, but I'd like to figure out what this is.
