hi all
I have got a problem with my vmc 1000 22. last week my hard drive died, so replace with new one today.
now machine start up, load software but since you try ref machine-power servos, blinking message is coming up on the display:
"s motor enc. zn ampl too small"
any idea?

is it possible you disrupted the z encoder cable when working on the control?
