Hi ,

I turned this machine on this morning and smelled something funny now my controller comes on but as soon as i hit the power enable button to reference the limits it trips a breaker (C4) in the back cabinet and the drives do not get turned on.
I changed the PSU , Changed all Axis drive cards including the power supply board. Checked the fuse in the control. I am not sure what to try next.

Any help is greatly Appreciated

Thank You
Ray
