Improved Snap On Guide for "|Robert|'s Alternative UM2 Feeder V2"

thingiverse

This is an updated version of the Snap On Guide for Robert's Alternative UM2 Feeder V2. I created this guide after attempting to use this feeder with 1.75mm filament, only to discover that it requires additional guidance underneath the extruder motor. During testing prints using the new feeder and 2.85mm filament, I encountered noise coming from the feeder, caused by the filament not being properly centered on the pressure bearing. To address this issue, I modified the additional guidance for use with the 2.85mm version as well. These two modifications enable effortless switching between 2.85mm and 1.75mm extruders by simply swapping out the Snap On Guide. Testing with 2.85mm has proven successful, completely eliminating noise from the feeder. For 1.75mm, I have only verified that feeding works properly; plans are in place to upgrade the Bowden tube, PTFE coupler, and nozzle before printing begins. It is likely that an update will be posted following this first print, but initial results indicate a high level of performance.
