Firmware Update
Help! I updated the Firmware on my MK4S (with MMU3) to "Firmware 6.5.3 (3.0.4) MK4S, MK4, MK3.9S, MK3.9". After I did that I get an error on my printer that the MMU is not compatible with this firmware. I looked at the website under the MMU and the update is the same name and size. What am I doing wrong? Should I just revert back to the old Firmware?
RE: Firmware Update
Did you update the MMU firmware too? With a USB cable from Prusalicer.

It does not say anything about that in the MMU Firmware update write up .. How do you do that?

It's a pain in the rear end — you need a laptop (or printer next to a desktop) and a MicroUSB cable — with the first one I tried Prusaslicer didn't recognize the printer.

RE: Firmware Update
Thank you! That led me to what I needed to know! I got it. And yes the orginal cable is needed. What a pain! I tried another longer cable but that did not work. I found the original cable it it worked like a charm. Now everything is updated. Thanks again!
