Printrbot Y Axis Belt Tensioner

thingiverse

Regulate belt tension on your y-axis by turning screws. Follow these steps: 1) Drill two new holes on the print bed near existing ones for the belt retainer, and align the pass-through hole with the retainer. 2) Assemble the casing using screws from the belt retainer kit. 3) Run the belt through the casing and mark its tight position inside. 4) Remove the belt from one retainer, loop it through the insert's center hole and pin, then secure with a zip tie. 5) Secure the insert in the casing using two adjustment screws and hex nuts. 6) Reattach the belt to the far end retainer and secure. 7) Fine-tune tension by turning the adjustment screws on the insert's front face. Ensure it's not too tight, causing motor stalling or component strain.
