Tension the Belts

Step Type:

Drag to rearrange

The belts in the Rostock MAX v3 are tensioned by rotating the stepper motor towards the center of the printer.

If you've pulled the belt tight when installing the last belt retaining clip, you only need to add a little more tension to the belt. Rotate the stepper motor so it's about 1/4 the way across the screw slot and tighten all four screws. Do this for each stepper motor.

Note that you don't want the belts to be so tight you can pluck them like a guitar string. The more you tighten the belt, the harder the motor has to work in order to move the carriage.
