As there are no actual DRO scales on the Series II CNC Rigid Ram the problem has to be isolated to the actual control circuitry.
A couple things I would check:
1. Remove circuit boards one by one, run a pencil eraser across the edge card connectors on both sides so they shine again and then re-seat the board in the slot.
2. Insure that all connectors at the front of the controller cards are seated properly by removing and reinserting.
I Just got a hold of a manual which I am hoping may have a set of controller schematics (don't hold your breath just yet). I will check that and see if I can't get you closer to where the issue may be if you still are having problems.
