Elk's Simple Belt Route for Mendel-X-Axis

thingiverse

This update aims to modify the existing RepRap Mendel's X-axis belt route in a simple and accurate manner. The creator of this design faced issues like frequent belt wear and backlash with the original belt path, prompting them to introduce an improved modification. The new X-axis design is inspired by the Prusa Mendel style belt system and another similar idea found on Thingiverse (http://www.thingiverse.com/thing:11820). This update requires minimal effort in terms of material usage while ensuring the best possible results. It doesn't require any additional parts for the X-carriage and keeps most of the idler side of the X-axis untouched. However, it is advised not to over-tighten the flipped belt to prevent potential damage due to excessive stress. An alternative version of the idler guiding roller wheel for the belt is also provided in the design to minimize wobble on the axis. To install the new belt route, remove the X-Axis belt and motor, disassemble the idler plate bearings, fix the motor with two outer motor screws to the new bracket, mount the new motor bracket using existing clamps and screws, attach the idler bracket extension in the removed bearing holes, drill out the hole of the idler wheel, press a bearing into the guiding wheel, align and mount the idler wheel properly, and finally mount the belt with desired tension. Flipping the belt by 180 degrees on the returning path is recommended for smoother running. The belt tensioner found at http://www.thingiverse.com/thing:24197 can be used for optimal belt tensioning.
