Hello to everyone , im making my own corexy machine with skr 1.3 board , tmc2209 driver for all axes and klipper as a firmware but im getting issue about sensorless homing.
Generally i have 2 issue and i guess if i solve one of them , other one is unnessessary.
First one is when i try to connect my tmc2209 driver to board and klipper with all jumpers below driver is removed , its giving me an error as " Unable to read tmc uart 'stepper_x " , my firmware cant connect to tmc driver.
then i solved that issue with putting 1 jumper below driver as you can see at picture (one guy said that in forum) then it works , error was gone and i can connect to tmc driver with klipper. the problem here is for tmc2209 uart connection , docs are saying , "remove all jumpers below driver" , but i have one at there.
second one is when i solve connection error with one jumper and try to home without sensor (with tmc stallguard) driver cant sense mechanical limit . just hitting to y axis carriage and trying to move on. i double checked to be sure and connect an LED to DIAG-GND pins and tried again , but tmc driver not sensing any step loosing , my led didnt turned on never.
as a final , i didnt find any solution about this problem. Please help me about this issue.
My board : BTT skr 1.3
S Driver : FYSETC TMC 2209 v3.0
Firmware : Klipper
