No communication between printer and MMU #7

Hi, 1st of all thanks for the code,. I love the project and being able to make your own MMU is so cool.

I have the MMU firmware uploaded to an SKR mini e3 v2. Everything seems to work because it starts and homes the idler. The printer has an SKR v1.4 pro board, and it's able to reset the MMU, even respond after the MMU starts but then it just sits there and doesn't respond to any commands from the printer's LCD MMU menu.

Here's the serial output:

22:35:46.528 -> waiting for serial port 22:35:46.528 -> 6.0 16/12/21 22:35:46.528 -> Sending START command to mk3 controller board 22:35:46.528 -> Sending START command to mk3 controller board 22:35:46.528 -> Starting new beta v 1.0 22:35:46.528 -> Waiting for message from mk3 22:35:46.528 -> inbound message from Marlin 22:35:46.528 -> finished setting up input and output pins 22:35:46.528 -> Syncing the IdlerIdler homed 22:35:47.775 -> Inialialization Complete, let's multicolor print .... 22:35:47.870 -> MMU Command: 'echo:Unknown command: "start"' 22:35:47.870 -> ERROR: unrecognized command from the MK3 controllerMMU Command: 'ok' 22:35:47.964 -> ERROR: unrecognized command from the MK3 controllerMMU Command: 'echo:Unknown command: "ok"' 22:35:48.056 -> ERROR: unrecognized command from the MK3 controllerMMU Command: 'ok'

and so on...

Any ideas?

On the printer serial i get the error right after resetting the MMU 22:35:42.551 -> MMU <= reset 22:35:42.598 -> MMU not responding - DISABLED

Maybe there's a very short timeout on the printer FW? Like the MMU can't respond fast enough?

I'd appreciate any kind of help, thanks in advance!

The printer is running marlin 2.0.8.1
