6.5.3RC and MMU
Just upgraded my MK4S + MMU3 to 6.5.3RC and now cannot use it as it says its incompatible with the firmware on the MMU3 - thats fair enough but can I find where a compatible version for the MMU is? no ! Anyone point me in the right direction please or do I have to wait for the official release version.

RE: 6.5.3RC and MMU
The correct FW 3.0.4 for MMU is here:
https://github.com/prusa3d/Prusa-Firmware-MMU/releases/tag/v3.0.4
The FW is not marked as stable but it works.
