Description

My AMS started having trouble loading and unloading filament. After much investigation and trying everything to fix the problem, I discovered that a small part of the AMS's Internal Hub Unit, responsible for holding the Active Extrusion Wheel in place, had broken.

After much online research, I found a model part on a forum. After testing it, I optimized the print settings to suit my needs.

 

Profiles included for use:

  • PET filament
  • PETG
  • ASA
  • PLA Basic (I do not recommend)

Preferably choose a resistant material.
