BOM:
- 2x D2F-L switches
- 4x M2x10 screws (I use self-tapping to thread easily into the plastic)
- 1x PC4-M4 fitting
- 1x PC4 fitting (I think any size thread will work because the thread isn't used, but I'm using an M10 one)
- PC4 clip
- Whatever Bowden tube you are using
Happy Hare config for MBB board:
mmu_hardware.cfg:
sync_feedback_tension_pin: ^mmu:MMU_FIL_TENS
sync_feedback_compression_pin: ^mmu:MMU_FIL_COMP
mmu.cfg (add to bottom):
MMU_FIL_TENS=PB4,
MMU_FIL_COMP=PB3,
I ran two separate ground wires before I realized it wasn't necessary. You can simply run a jumper between the two grounds and run one ground wire to the controller.
