Video 4: Instructions for adjusting the timing belt on the ELEGOO PHECDA.

Adjustment Steps (X-axis timing belt):

1. Remove the shading plate in front of the X-axis.
2. Check if the X-axis belt is too loose.
3. Use a 2.0mm hex wrench to loosen the two fixing screws on the drive wheel assembly behind the X-axis. (Loosen but do not remove the screws).
4. Press the X-axis left synchronous wheel assembly to the left, so that the X-axis belt is in a tight state, while using a 2.0mm hex wrench to tighten the fixing screws of the drive wheel assembly.
5. Press the X-axis belt to ensure it is not too loose or too tight, and the laser head can slide normally.
6. Install the shading plate in front of the X-axis.

Adjustment Steps (Y-axis timing belt):

1. Check if the Y-axis belt is too loose.
2. Use a 2.0mm hex wrench to loosen the two fixing screws on the left drive wheel assembly of the Y-axis. (Loosen but do not remove the screws).
3. Press the Y-axis drive wheel assembly to the right, so that the Y-axis belt is in a tight state, while using a 2.0mm hex wrench to tighten the fixing screws of the drive wheel assembly.
4. Press the Y-axis belt to ensure it is not too loose or too tight, and can slide normally.
5. Adjust the timing belt on the other side of the Y-axis in the same way.
