Y Belt Installation and Tensioning

Table of contents

Compatibility: Prusawire - Beta 1

Overview

The Y belt must be installed and tensioned properly to ensure smooth and accurate bed motion.

Important notes:

  • Extra belt length has been specified in the BOM; it is expected to have some leftover belt afterwards.
  • DO NOT cut your belts until you are 1000% certain you have done it correctly. It’s okay to leave a little extra length hanging out until final assembly and validation.

See the supplemental Y Idler Assembly - Prusawire 2025.B1.pdf for instructions on the revised Y Idler.
