MMU3 Firmware problem on MK3.5S...
Hi everyone. I've just done the MMU3 update on my MK3.5S and it says that the MMU3 firmware needs updating. I downloaded the file from the main Prusa site and it links to the firmware zip for the MK3.9S and MK4S. I tried version 3.0.2 from GitHub but that keeps showing the version error! What can I do? I have the 6.2.0 Mk3.5S printer firmware installed.

Have you tried MMU3 firmware 3.0.3

Oddly the mk3.5S MMU3 link takes you to the Zipfile for Mk4 and Mk3.9. but there is a hex file for MMU3 V3.0.3 in the unzipped folder

RE:
Thanks Joan. I've finally fixed by changing the filename in the downloads URL, so the correct file is there and contains the correct (& compatible) firmware for both the printer and the MMU3.
Now I've just go to find out why the filament stops half way to the extruder?! Oh joy! 😆
UPDATE
=====
It seems that it was a problem with the filament. Unloaded it, cut a section off and shaped the tip better into a point and it just worked perfectly.
