Bigtreetech MMB Can V1.0

[ddasty65]

Hi guys , i'm struggling with ECRF V2 MMU . I have faulty driver M2 that makes the selector work , i want to check if the MMU can be used or fall in the recycle bin .

Since that it has 4 driver for motor how i can set mmu.cfg alias associations ? 

I can choose any driver or there is some rules to follow ?

 

Many thanks for help

Move the selector to motor 3 if motor 4 is faulty and define as such. Easiest way is to change the pin out definitions in the MMU_SEL_XX section.

So for motor 3 it would be:

MMU_SEL_UART=PC6
MMU_SEL_STEP=PD0
MMU_SEL_DIR=PD3
MMU_SEL_ENABLE=PA15

The MMU_SELECT_DIAG, MMU_SEL_ENDSTOP, and MMU_SEL_SERVO will stay the same.

Hi mvdeveer many thanks for the tips.

I asked this for an issue on selector motor that no longer turned , seems died.

After some test as specified by you i moved motors to gate M3 and M4 without results .

I happened to be reading a post for update happy-hare files for a similar issue : i removed first current installation and again reinstalled Happy-hare .

Now all works well .-)
