    I have cutting problem with my cutter. The fault is that lack in 1 or 2 mm
    Example when I make 61cm cut and repeat manually cut 61cm
    I found there is lack 1 or 2 mm
    I swap PI card from another machine
    And the problem is still found
    The problem from brake or lms or PI potentiometer

    Try switching machine off while backgauge running. Then machine will need calibrating. This will reset braking distance

    Hi sir:

    Before to do something with the electronic system check this steps:

    Overcut:

    1)
    knife: blunt or slanted in the carrier knife , or counter phase
    rear of knife is crowned +wrong angle knife +clamping pressure too high

    table: table is Not square to the knife carrier

    or
    b&gauge?: backgauge is NOT square to the table +knife carrier has play+

    Undercut:
    knife: is blunt +has burrs, has place slanting in the carrier knife +wrong angle knife +

    Hollow cutting line:
    1) knife angle is too slender
    2) clamping presurre too low
    3)incorrect knife fixing

    BOW- or hollow cut;
    1)The cutting material is unequal in height

    2)The cutting material is Wavy

    Oblique cut:
    1)Table is not square to the knife carrier

    2)Backgauge is not parallel to the knife

    3) slinding guides has play

    Please review carefully, remember the best invaluable tools in troubleshooting is : 5 Sense

    Blessing

    Thanks for your reply
    The machine now measures sometime shorter and sometimes larger than the value in the display
    This mean the value measured by ruler different from display
    We found that there is problem with the scanner head. There is a stripped wire touch lms

    Great job sir with the lms

    However , will Not available schematic for that, Only Polar has such documentation

    Normally, they sell the complete lms, Not for repair, you must use the Brain, for to fix it. Sorry :(
