Conveyor belt climbs over white limit ring. 

Common causes

  • Rollers are not aligned perpendicular to the table.
  • Conveyor belt is not aligned. Belt length on X2 side and X1 side are not equal.


  1. Belt tension and aligment / bracket adjustments
    (this information is copied from the Installation manual)

    Bracket adjustment "A": Belt tension adjustment
                                              Ensure correct vertical levelling

    Bracket adjustment "B": Ensure correct vertical levelling

    Bracket adjustment "C": Ensure the front and rear rollers are vertically levelled
                           Ensure they are parallell to the table top (see 2 a, b, c and d below for how to check the vertical parallellity)

    Bracket adjustment "D": Ensure the front and rear rollers top level is just above the top level of the table top

    Bracket adjustment "E":  If the conveyor belt seems to be too long, you should modify the fixture bracket instead of shortening the belt.

    This is how the bracket is mounted from the Factory

    If the belt seems to be too long,turn and fix the

    bracket as shown here

  2. Roller alignment

    In order for the belt to track properly, the front and rear roller must be aligned vertically to the running direction of the belt. 
    The off-center tracking of the belt seen here occurs when the roller is not positioned at a right angle to the running direction of the belt.

    1. Use a try square and put it against the front roller on X2 side. Mark the end of try square with tape and pen. Do the same on all four corners of the machine.

    2. Jog traverse toward the front roller marks and check both marks with the laser pointer. Adjust front roller until marks are aligned with laser pointer.
    3. Do the same for the rear roller.
    4. Check the distance from table to the lower front roller and the distance from the frame to the lower roller on X1 and X2 side. Do the same on rear side of the machine.

  3. Straighten the belt

    In order for the belt to track properly, it is absolutely necessary that the belt itself is straight.

    1. Remove tape markers connected to the rear roller.
    2. Do a table feed. Open i-cut, direct command for table feed is "Ctrl + 1" (Don't have a feed rate higher than 20% Acceleration and 10% Speed).
    3. Use a measuring tape. Measure and mark the feed distance on both sides. Start measuring sequence from your tape marks for the front roller on the conveyor belt X2 and X1 side.
    4. Note the distance for each feed. Repeat this sequence until conveyor belt has rotated one lap.
    5. Sum up the measured distance from the start mark to the last mark. You have now calculated the length on belt for both sides.
    6. The deviation shall ideally be zero. We have seen problems with climbing belts if the deviation is more than 5mm.
    7. Cut and re-glue the belt so the length is equal on both sides.
