¶ Loose belts (X-axis or Y-axis)
¶ Problem Description
- The starting and ending points of the cut product are misaligned or do not close accurately.
- The edges of the lines exhibit slight waviness or vibration patterns.
¶ Cause
The belts on the X-axis or Y-axis is either too loose or adjusted too tightly.
¶ Solution
Important Note:
When adjusting the belts, it is crucial to achieve a moderate tension. Belts that are either too loose or too tight on any part of the machine will negatively affect performance.
¶ Adjusting the Y-Axis Drive Belt
As shown in the image below, loosen the three screws in Group A to unlock the Y-axis motor bracket. Then, turn Screw B to adjust the belt tension. Once a moderate tension is achieved, re-tighten the three screws in Group A.
¶ Adjusting the X-Axis Drive Belt
As shown in the image below, loosen the three screws in Group A to unlock the X-axis motor bracket. Then, turn Screw B to adjust the belt tension. Once a moderate tension is achieved, re-tighten the three screws in Group A.
- Standard Tension: When adjusting, the belt should be in a state of moderate tension. This can be assessed by the finger press test, which should allow for a slight movement margin of approximately 1 to 2 mm.
- Over-Tension Assessment: If there is absolutely no movement when pressed, the belt is over-tightened and must be loosened slightly.
¶ Final Check
- After adjustment, manually push the laser head to slide it along the X and Y directions, observing for any sticking or abnormal noise.
- Rerun a test job and check if the starting point and ending point misalignment issue is resolved.
