Need Assistance with SPI2 Configuration Issue in Klipper / Spider 2.2


New member
Hello everyone,

I am facing an issue with SPI2 configuration on my Voron printer running Klipper. I need to use the PB14 pin for a different function, but it's reserved for SPI2. I have attempted to modify the configuration using make menuconfig without success.

The log from Klipper indicates the following: BUS_PINS_spi2=PB14,PB15,PB13. I would like to reassign or disable SPI2 to free up the PB14 pin.

I have followed the documentation and looked into the printer configuration file, but couldn't find clear instructions on how to modify SPI2 settings.

Any guidance or suggestions on how to resolve this issue would be greatly appreciated. Thank you in advance!
