MKS Robin Nano V1.3 STM32F407 - Klipper not flashing properly

Basic Information:

Printer Model: TwoTrees Sapphire Plus 1.1
MCU / Printerboard: STM32F407 / MKS Robin Nano V1.3
klippy.log

klippy (4).log (409.0 KB)

When flashing via SD the its first erasing some sectors, following up is updating, which takes about 1 second to go from 0% to 100% then it is stuck at 100%.
When starting the printer after flashing, it only says “Booting…”.

I double checked everything and redid the whole firmware configuration. I used kiauh’s klipper installation and update helper, setting up the raspberry was a blast.

I tried using different microSD cards and that didn’t change anything (read about a dude trying different ones and suddenly it worked)

Really grinding on my nerves since I was hyped to switch to klipper.

Thank you for reading & thanks in advance for any suggestions!

Closely follow Installation - Klipper documentation and klipper/generic-bigtreetech-skr-v1.3.cfg at master · Klipper3d/klipper · GitHub (mind the information on top of the file)

Your build / make settings and config do not match

Fist of all - thank you very much for the quick answer

I find this quite interesting - the chip on the board says STM32F407 - am I stupid and not understanding something or is TwoTrees possibly using “fake” BTT boards / custom boards with a different chip?

I really want to understand this topic and not just get it fixed (even tho thats the top priority) in order to help other people that might encounter a similar problem.

I think I’ll redo the klipper from scratch and document it step by step in order to get any issue sorted out instead of tinkering around with it without having a clue what I’m doing.

Pretty new to Klipper, previously had an ANET ET-5 which I got working really good on marlin 2.0, but I obviously had to have a corexy machine :smiley:

In the first post you are stating that you are using a BTT SKR 1.3 board. The make instructions are of course depending on the printer board that you are using.
A BTT SKR 1.3 with a STM32F407 chip does not exist.

I’ll double check asap, I really hope I just messed something up.

Will update

So apparently I am a stupid pos
I dont know my brain processed what I saw - the installed board is a Makerbase MKS Robin Nano V1.3
Thus the fuckup with the MCU

I suppose that changes the whole situation about problem (the 3d printer problem, not me being stoopid :p)

Figured it out

followed this thread and it worked.

Thank you for handling my stupidness :'D
