Re: [CAD_CAM_EDM_DRO]

I am not a CNC techie but have helped repair a few I have worked on. I ran a
G&L horizontal with a numeripath 8000B control that you could see the servo
feedback in the ladders on the control CRT. But to be honest I have seen
most of these trouble shooted by switching out axis boards. Don't know if
this will help but hope it does
