Introduction

The printer uses very thin layers of filament, so any sort of movement outside of the precise instructions given to it will result in failed prints until a fix is made. This guide will illustrate how to turn the eccentric nut connected to the loose wheel bearing in order to secure the wheel bearing to its railing.

Before beginning this repair, disconnect the printer from its power source and make sure the print bed is cooled to room temperature.
