BELT TENSIONING
The printer belts will occasionally need to be tightened to ensure optimum performance from your printer. The belts on each tower
should be tight enough to pluck gently, similar to a guitar string. If the belts are too tight, the stepper motors will stall, but if the
belts are too loose they could skip a tooth on the pulley. Follow the steps listed below for easy belt tensioning.
Note:
Only tighten one belt at a time to prevent the top support from dropping.
1.
Loosen the two screws on the top side of the tower that holds the belt that needs adjusting.
2.
Place your thumb under the lower screw and your pointer finger on the top of the rail. Push up with the thumb until the
belt is to the desired tension. Tighten the two screws to secure the new position.
