Has anyone a schematic for the FAC-1R board of a KTK spindle drive.I have info I got a while back from George ( Machintek) which has the SOL 1 and MT 1 board drawings but not the FAC.
My fault is it is not seeing tacho voltage.When cold after a few hours it will run through one cycle ok but faults immediately at the start of the next one.
Mark.
