Unable to upgrade MMU2S firmware to 3.13.* #4417
Comments

You can just update the MMU2 with a cable directly in the MMU2 from
PrusaSlicer with the MMU2 hex file

… I have 2 MK3S+ (with MMU2S) printers. Before version 3.13.*, when I
updated the printer firmware, the MMU2S firmware was also updated
automatically.
But when I upgrade to this latest version (3.13.0, 3.13.1, 3.13.rc2) only
the printer is updated, and when I activate the MMU in the settings it says
that I have to update its firmware too.
I have tried this on both my printers with 5 different cables, I even
bought 1 new data cable, and there is no problem with data exchange. I also
tried it on both macOS and Windows but the result is always the same. It
gives the following error. I have also contacted live support about this
but they have not found a solution either.
As a result, I had to revert back to 3.12.2. I don't know if anyone else
has this problem, but I couldn't upgrade.

I guess you didn't read exactly what I wrote. That's exactly how I tried it. Also, There is no separate hex file for the MMU2S. |
|
Looks like you try to update the MMU with the printer firmware. You need to download the separate hex file for the MMU. (The one I linked is compatible with Printer Firmware 3.13.2-RC1) |

Sorry. I just answered what you wrote: "Before version 3.13., when I
updated the printer firmware, the MMU2S firmware was also updated
automatically"
I have never seen this been done automatically. I have always done this
with a micro usb cable from the PC to the MMU2+.
And with the last version, I also did a "manually" update but with success

@tbatur You are trying to flash the printer firmware on the MMU. This will never work! The MMU has it's own separate Use this MMU firmware with 3.13.0: For 3.13.1 and 3.13.2 you will need MMU FW 3.0.1 |
It's done now. I didn't try it because the name of that file only says MMU3, thank you. |
Yes, it is done with that file, but they should fix the name of that file. Because of the name it looks like it's only for MMU3. |
|
Closing as resolved. |
