Belt tensions

Recommended Posts

After making some prints, I went back to fix the belt tensions as the printer seemed unable to print good-looking round forms.

By adding some additional tensioners on the x-axis belt the prints improved, however the X stepper belt seems to have loosened after the assembly. When the stepper changes rotation direction, I can clearly see the belt move a little sideways.

Unfortunately I cannot tension it anymore, as the stepper is already at the lowest position allowed by the mounting holes.

Before extending these holes, any other point to check or suggestions?

Small side movements are not really a sign for belt slack, but misaligned pinions, and are not detrimental to the printing process.

If your belts make the spoing sound when plucked, you're good. Otherwise extent the stepper mounting holes, I did that as well.
