MMU2, MMU2S, Multi Material Unit V2.3

Last crawled date: 3 years, 2 months ago

Numerous modifications of the original models for more stable loading and unloading filament (4/2.5 PTFE tube, better material (CPE-HG100) higher resolution and other bearings and linearguides for more precision).
Since i'm working with this modified MMU2S the known problems have almost disappeared.
In picture nr.8 (58) you can see the difference between the original PRUSA and my printed part.
Attention!! Take a look to picture nr.13 (63) -> (see Update from 20.11.2019)

Update 30.10.2019: partslist.xlsx - Stützrolle Messing 5x60mm -> Stützrolle Messing 6x60mm
Update 20.11.2019: Important!!! Shorten the original Prusa pin screws M3 and adjust it to the pully outerdiameter otherwise they will crash with the brass roller (see picture 13)! If you don't want to shorten the original ones, buy M3x2 and shorten this!
