To adjust the pulley tightness on the 3DJAKE CR-M4 3D Printer, follow these steps:
1. Before switching on the machine, gently toggle the pulley with your hand and check if it is idling or stuck.
2. If the pulley is idling or stuck, use an open-end spanner to adjust the hexagonal eccentric isolation column.
3. Rotate the hexagonal eccentric isolation column until the pulley rotates smoothly.
Please refer to Figure A in the user guide for visual guidance on adjusting the pulley tightness.
Note: It is important to check the pulley tightness before turning on the machine to ensure smooth operation and prevent any issues during printing.
