Can anyone help? Our Wohlenberg Guillotine 92 gave an encoder error so we were advised to put in a new pc board. Then the error went to the motor so we replaced the motor, again on the engineers advice. Now the blade wont come down and the original error is back A.C3... Im now done with this guillotine after spending so much on it... can anyone advise on what next to do besides burning it in frustration?
