What should I do if the layers of the printed model are obvious
1. After shutting down the machine, slide the print head part and the printing platform part by hand to observe whether the movement is smooth. If there is shaking, you can use the hexagonal wrench provided with the machine to adjust the eccentric column in the pulley assembly.
2. Check whether the timing belt is loose. You can adjust the knob on the belt tensioner to make the timing belt tension moderate.
3. Use paper towels and alcohol to wipe the Z-axis screw. After wiping it clean, please re-apply "grease" on the screw.
