No communication between SKR1.4 and mini 1.1

[LordDarkneo]

Hello, I am having an issue when trying to make my SKR 1.4 (on printer side) with my mini 1.1 (MMU2+1S side).

I tried with a stock MMU2S from prusa (original one) and the commands are correctly send and exectued (load filament). But when using the mini 1.1, nothing happens...

When powering on, the idler is "homing", extruder does not move. Whatever the command sent from the printer throught the screen, nothing happens on MMU2+1S side.

How to debug this? Thanks for your help

Hi, were you able to get this working? I'm stuck on the same step, the MMU homes, i can see that on the serial monitor but it seems it doesn't recognize some command from the printer. Thanks!
