I've setup three machines with Galil cards, AMC servo amps, and servos in the past. Last spring, I did a CNC mill and the X,Y,Z went fine and the 4rth axis failed. I didn't have time so I just got the mill running without the 4rth axis.

OK, I'm thinking bad component. So I got another servo, installed a BEI encoder, another AMC servo amp (25AE8), made up a small wire connector to go from pins 2,4,11 on the servo amp to ground, MOCMD_, and AMPEN_ on the Galil card.

Then I started swapping out components one at a time. No joy. So then I connected all the new componets to axis G (unused but available). No joy.
I just called it a day.

In WSDK, the failure has always been the same. It passes the hand spin encoder test. Then when I reset the Estop to power the servo it starts spinning and often trips the servo amp out.

What am I missing here?
