mmu2 Prusa-box enclosure integration
1. Original bracket and mmu2 board cover:
Unscrew the 4 x m3 screws to remove the original bracket and the 2 x xm3 screws to disassemble the electronic mmu board cover.
2. Cable extender:
Disconnect the pulley motor (yellow) and the selector motor (red) and add a cable extender.
Depending on your mmu2 delivery date, motor cable won’t have the same length. Cable extender is not always required for both motors.

3. Mounting part:
Assemble the mmu2 mounting part with mmu2 unit.
/!\ To preserve PTFE tube, the mounting part has to be mounted at the right distance: 183-184mm from left side of the enclosure.
4. Slider:
The slider must slide freely. Depedending on your print quality, you may have to remove the edge.
Lock the slider with a m3 screw.
/!\ Don’t screw it all the way.
6. mmu2 electronic board:
Install the mmu2 board base with 1 x m3-6 screw from inside the enclosure.
/!\ Make sure that the cable isn’t squeezed
7. Preflight check:
/!\ PTFE tube: the PTFE should be long enough, but in any case, you must check if the PTFE is long enough for the extruder to reach the X axis left and right extremities when it is in the lower Z axis position.
Congratulations on finishing mmu2 mounting part!
