I’m trying to configure an existing BTT EBB36 can module from other printer in my new Voron 0.2 but klipper is not accepting my configuration With error “Pin ‘PA15’ is not a valid pin name on mcu ‘EBBCan’” Relevant Configuration: [mcu EBBCan] canbus_uuid: d05fdfdf7adb [tmc2209 extruder] #uart_pin…

Missing a space between EBBCan:PA15 should be EBBCan: PA15

Then the klipper firmware is not created for an STM32G0B1

According to the github link in post #1, the UART pin is PA13, not PA15

@EddyMI3D V1.0 PA13 V1.1 & V1.2 PA15 BigTreeTech%20EBB36%20connections%20information.pdf

In deed, but that is another site…

Directly from BigTreeTech the manufacturer. More than likely the firmware was complied with the wrong STM32. The V1.1 & 1.2 have the G0B1.

always post klipper.log, it tells the truth

Possible, yes … But i Have done a roll back in klipper (like 50 commits or so) through kiauh and it worked. If it was a a wrong STM32 it should have not worked at all. Made an update now and all seems ok.

Pin 'PA15' is not a valid pin name on mcu 'EBBCan'
