This is the result of several months of designing and testing new ideas for increasing the filament count of the Prusa MMU2S. (And then more testing and re-designs for the MMU3.) I tried several variations, but ended up coming back to something that is largely based on the original Prusa model. Some of the major adjustments include:
- increased filament count from 5 to 12
- reversed position of pulley and idler motors, to maximize the use of the 110mm pulley shaft
- moved FINDA to the rear of the selector, in an attempt to minimize issues where the filament clears the ball but then still fails to fully retract
- quick-release insert for FINDA sensor, for ability to clean or check ball chamber without re-calibration of FINDA height
- selector has integrated threads for PTFE quick-connect
- moved control board beneath the body (inspiration thanks to univeraljoint)
- additional bracket mounting options
- selector does not include the cutter
As of October 2024, this project has been updated to include the MMU3 with the Mk4. New features now also include:
- a new idler alignment gauge of the front side of the upper frame
- a streamlined idler design
- a smaller inlet that uses the PTFE collets instead of M10 screw connectors
- a cover panel for the power connection board
