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!

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

i try to compile the firmware before modify the parameter of bowden tube but i got this problem?????? im using vscode and platform...

Good evening,
I am in the process of building a MMU2S clone. I have the parts printed and almost everything assembled. Now I wanted to take care of the board for the control. I bought a BTT SKR mini E3 V2.0.
Now I wanted to compile the firmware with Visual Studio code, but I get constantly an error.
Attached also a screenshot of the error.
I have tried compiling with Windows but also Mac, but get the same error with both.
