Re: compact 5: advance motor "humming"


Hi, is the X (cross slide) motor working OK ?
If X is OK then the problem will be most likely on the stepper control board, not the Bridge rectifier I said earlier when I thought both axis were not working. The Bridge rect is about 1.5" square shape and has 4 connections on it, 2 for the AC in from the transformer and 2 outputs which are DC. Look inside the back at the top right of the control cabinet.
