    Dear,
    I have issue with my cutter...
    When I want to cut to have 150mm then I get 151mm. Always there is kind of the same offset... Calibration of position is not helpful. So somehow I need to teach my Wohlenberg that 150mm is 150 not 151mm.

    Can you help me with this?
    Additionally if someone can sell service manual for Wohlenberg 115 pro-tec (2005) I will be very interested...

    thanks a lot and regards
    Krzysztof

    Hi,
    I don't have experience on this model. But I'll tell you a trick to correct the measurement.

    The distance measuring device (we call it encoder) I hope it is mounted under the front table next to the handwheel. The shaft is attached by a belt. Try to do this, but be very careful because small mistake can worsen the situation.

    Turn on the machine and run the backgauge to a known position, let's say it is 150mm. (So that your actual position will be 151mm) and make sure the brake had engaged and it cannot be moved by hand. Then loosen the encoder holding screw and rotate the encoder body until the display shows 151mm. Then tighten the screw. And you're done.

    But before doing this adjustment, make sure the belt is in good condition and not loose too much. In that case you have to replace the belt and adjust it.

    Hope this helps.

    Hi
    Thanks for your answer and support...
    Unfortunately i known this trick but in my case it is not aplicable... the backguage is moved by serwomotor with builtin encoder. Now possibility to change position of this encoder...
    I need to this modification by software....
    Thanks
