How do I fix the grinding noise coming from the CNC machine's motors?Updated a month ago

If your CNC machine's motors produce grinding noises, inspect the following:

1. Ensure that the belts are free of dust and have the appropriate tension.
2. Check the synchronous wheels and ensure the belts are positioned correctly without offsets.
3. Adjust the eccentric nuts. If they are too tight, loosen them; if too loose, tighten them correctly.

If after these checks the issue persists, replacement of the motor with the correct specifications may be required.
