RE: New MMU3 firmware upgrade on MK3S+ with MMU2S
I was following this post : https://github.com/prusa3d/Prusa-Firmware/issues/4285
And Arduino 1.8.19 is what he was using, so that is what I tried and was able to send the commands.
https://www.arduino.cc/en/software - You have to scroll down the download page, to the "Legacy Software" section.

Thank you. 1.18.19 Did not work for me. I can see the scroll but when I put in either command to read or write all I get is "ok" prompt. Baud is set to 115200 so I don't know what is going on. I type the command in and tried coping and pasting and neither work. Just keep getting "ok" response. I finally downgraded to 3.12.2. and everything works no. I wrote to Support and will see what they say.
RE: New MMU3 firmware upgrade on MK3S+ with MMU2S
I have been having the same problem with the 3.13 firmware. My MMU is a very very noise paperweight with that firmware. Luckily I was able to revert to the old 3.12 firmware and was able to get everything behaving as expected.
Any word from Prusa on when they'll have a stable firmware that works with the MMU2S?
