    I have a polar 137 EMC that the cut is 1/4" off of the value that is input. If I put 10" into the program the actual cut is 10.25". Is there anyone who can help with instructions on how to recalibrate the cutter to make it correct again?. Thanks in advance

    Hi. In the panel under the front of the bed is a rack of PCB,s . One should be marked TAM on is board should be some red adjustable pots numbered 1 to 8. These are designated in mm 1/10 mm,1/00mm these are used to calibrate measurement. Write down starting settings then adjust small amounts and run back and forward check measurement. This can take a while and trial and error. There is a calculation that can be used but I find trial and error easier
    Good luck
    Andy

    You can not adjust a difference of 1/4 inch from a TAM card.

    Hi remember:

    After adjust the TAM or before , you must test:

    1) The backgauge is not square to the table

    2)Table is not square to the knife carrier

    3)Backgauge not parallel to knife
