Hey Guys. I need some help with setup of Fysetc TMC2209 V3.0 drivers for MKS gen V1.4 board UART mode, especially Marlin configuration. Stepper drivers pins are labeled correctly. how can i use different slave addresses? i don't want to break or move any pins. wonder why marlin is not able to setup pins to high or low, based on UART communication. Can anyone explain how to configure marlin to use UART with these stepper drivers?
