Belts are the main driving elements of our 3D printers. The belts used in our printers are robust and withstand all the forces exerted on them during printing. But sometimes they get damaged. Since belts are the main workhorses of the machine, even a minor issue with a belt will cause errors in printing. Periodic checking of belt wear and tear marks is necessary for the smooth functioning of the machine.
In case your machine is layer shifting, do the following checks.
1. Check belt tightness: The belt should neither be too loose nor too tight. In simple it, it should be firm like a guitar string. If the belt is too tight, there is a chance of the belt getting damaged, and also, extra load is exerted on the motors. If the belt is too loose, layer shifting will occur. If not layer shifting, the print quality will be reduced.
2. Carefully check belt teeth: If belt teeth are damaged, the movement of the extruder head will have some play. This play will cause a reduction in print quality. If the teeth are damaged, the belt needs replacement.
3. Check belt edges for damage: If the belt is rubbing against the pulley, or if the belt edges get damaged. If the edges are severely damaged, the belt needs replacement.
