I am trying to resurrect a Biesse 336 and keep getting a S0157 "Head Interference" error which is preventing the unit from homing/zero. If I just manually jog the axis the axis moves but then stops with a S02 error which is normally an emergency stop error.
I am picking the S0157 error is causing the PLC to error and prevent damage. I have checked the obvious sensors for head height etc and all look fine. It was running fine previously (like a few weeks ago), but now wont do pass this error.
Where could I check next??? Running a RT480 controller.
Thanks
