Hello, i recently testet Klipper (MainsailOS) on my Ender 3 and now I don´t want to go back to Marlin. At the momant I am rebulding my Anycubic I3 Mega S with a Skr 2 but i cant get it running.
I don´t now why i get the error : mcu ‘mcu’: Unable to connect
Thanks
klippy.log (17.1 KB)

[mcu]
serial = /dev/serial/by-id/usb-STMicroelectronics_BIGTREE_SKR_2_CDC_in_FS_Mode_2074337D5232-if00
The serial entry looks like Marlin. Most likely flashing your SKR 2 did not work. Repeat the process and follow the top of klipper/generic-bigtreetech-skr-2.cfg at master · Klipper3d/klipper · GitHub
firmware.bin will get renamed to firmware.cur on the SD card. Afterwards correct your [mcu] entry with the new device name
Nevertheless it can happen that you need to do multiple flash attempts if you have a picky board.
Thanks.
Now it works fine
