Hi
I wonder if it is possible to use the Fysetc TMC2226 stepsticks (https://www.aliexpress.com/item/4001197387822.html) in the S6 controller ?
The description states "For SKR V1.3", and from the schematics of the S6 and SKR v1.3 boards, it looks like BTT and Fysetc use different pins for the UART connection on the stepstick; and there is no schematic for the 2226 stepstick on the Wiki (that was my first target for trying to see if it was possible)..
Regards
Brian
