Keep getting randomly a clamp unclamp error message. Machine can run all day and nothing, then other days it happens every few minutes. Sometimes code clears right out other times it will not go away. Had randomly it throw spindle orientation error, atc not home error then clamp/unclamp error back to back to back.

Checked Prox sensors below rotary union, all seem to function correctly. Adjusted multiple times.
R&R drawbar no broken washers
replaced air switch that operates draw bar

Appears to be no broken wires.


Could this be in the Computer? Bad hard drive or boards?

Any help would be appreciated.
