Y-axis timing belt tension is most accurately measured using a BRECO meter. Should a BRECO meter not be available, the Y-axis timing belt tension needs to be measured as described under Y-Axis Timing Belt Tensioning in this manual.
The specification for Y-axis timing belt tension is 45-50 Hz (or 8.1 ± 0.3 lbs with the force gauge). The x-beam must be pushed all the way to the front of the machine when using the gauge. The measurement should be taken at the center of the Y-belt.
Should the belt tension be out of the specified range it needs to be re-tensioned. Use the guidelines outlined in Y-Axis Timing Belt Tensioning.
