Hi,

I've just purchased the SKR 1.4 Turbo & TMC 2209 for my CR-10S printer and have a few simple questions.

A:- Do I set it up for UART mode, if so do I leave all the black jumpers on or not

B:-How do I set it up for sensorless homing

Thanks in advance for any help you guys can give.........

A. yes UART works look at the manual here: https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/blob/master/BTT%20SKR%20V1.4/BTT%20SKR%20V1.4%20Instruction%20Manual.pdf You can see the jumpers you need to leave in. Page 7. DO NOT CUT THE PINS as you need stallguard for sensorless homing

B. watch this video (NOTE THIS IS FOR A SKR 1.3) but the SENSORLESS_HOMING is the same: https://www.youtube.com/watch?v=H5ea2iyOscg&t=593s
