(EDIT) MK2MM Upgrade with Rambo10a failed FW 3.0.12 rc1

Hello,

I can´t get my printer work again after MM upgrade, last night.

The new FW 3.0.12 rc1 seems not to work for me.
It shows only squares on the screen after flashing the 1_75mm_MK2-RAMBO10a-E3dv6full.hex .
If i downgrade to 3.0.10 it works again, but without the functionality of MM.

I tried to flash 1_75mm_MK2-RAMBo13a-E3Dv6full.hex also, with the same result.

I wonder why both files have 652 KB?
All other/older FW have been having a difference of 1 KB ??

Did anyone has success upgrading an MK2 with 10a Rambo board?

What else can I do?

Regards, Elmar

Printer: Original PRUSA i3 MK1 kit with all upgrades to MK2

So it seems that none can help..... 😕 😉

After some investigations I loaded both .hex files (10a/13a) into DiffMerger, for comparison.
and this is the result:

If I compare the 3.0.8. .hex files DiffMerger shows significant differences.
Maybe I´m wrong but my guess is: Someone did it wrong by naming/uploading the files.

The other thing is, that the Display shows only squares after flashing. No matter wich .hex file I use.
Which always facts by flashing a wrong FW for that spezific board.

It wold be nice to get some response this time.
Unfortunately I m not able to compile the FW of my own, this moment .

Thanks in advance
Elmar

Hi guys,
new firmware for 10a is ready. Josef will upload it to the http://www.prusa3d.com/drivers , I will let you know when it is ready.

If you know GitHub and which .hex file to pick, you can download them now. Proceed with caution.
