Working on it this afternoon, I hope. Borrowed an o'scope to check out a 
suspect power supply and compare waveforms on the encoder lines. This 
machine had problems of repeating when it had Gecko's on it and I want 
to check out some of the signals.

  Z will rapid at 100IPM but at 120 it will fault ( red LED on amp) when 
stopping the jog from one direction only, other way is OK. When at rest 
I can turn the dials farther in one direction than the other against the 
amp compensation.
