SKR3 with TMC2209 v1.3


Recommended Posts

Hi all, first of all I'm new to Klipper, I "customized" my Biqu B1SE Plus with an SKR3 and TMCs 2209 that i have to use in UART mode. I compiled the firmware, set up the Raspberry, set up the Can-Bus cause I have an Hermit Crab CAN and an H2V2S Revo, it's all working but I can't make the motors move, I have the right pins, right jumpers, the right config but I keep having the error : Unable to read tmc uart 'stepper_x' register IFCNT for all the steppers except the extruder that is moved by the TMC2209 embedded in the hermit crab, do I have to solder something on the drivers? They're version 1.3 and if I search on Biqu site there are some instructions, but for 1.2 drivers lol  There's a top image with v1.3 and the bottom image of a v1.2 completely different from my v1.3, hope someone can help me. The last chance for Biqu/BTT, next time I for sure buy another brand, their instructions always lack something.
