We have a DEK 260 with a intermittant table align stepper motor problem. The machine will work fine for awhile and then one of the table align motors starts either moving hapazardly in small increments back and forth or vibrates as if it wants to move but does not move. We have tried swapping out the motor, swapping out the driver and stepper cards and still, the problem persists. Has anyone else out there had a similar problem with a DEK 260 (or any stepper for that matter). I keep telling the techs that it might that the cable is frayed or something to that effect (what else could it be?) but they don't seem to think so. Is there anything I might be overlooking here?
