prusaprinters
The MMU2s requires some love to get up and running reliably. In order to prevent constant babysitting down the road a proper test is required. Enter the MMUTT - MMU torture test: 1000 tool changes, 5 colors, printing time ca. 20h (sliced 0.2mm). The model is optimized to save filament, each color has only one thin strand printed per layer. You can use the provided gcode or slice your own. The presliced version is configured for “generic PLA” and has greatly reduced purging volumes (15mm3). This saves filament, however, it leads to one color bleeding into the subsequent one. Slice your own if pristine colors are a priority.If your setup cannot print the MMUTT without assistance have a look at NoMBa.
