sage zinc
I built my first voron (voron 0.2) and i went through the checklist of installing klipper and mainsail.
I use a bigtreetech pi and a BTT skr pico (tmc2209 Drivers).
the issue is that when I sent the comand to home to the printer, the z axis homes correctly with the probe on the bottom, but the x and y only move a little bit before stoping the homing process.
I sadly have no clue whats causing it, I even shorted the correct pins on the board.
any help is apreciated.

step_pin: gpio11
Refer to https://docs.vorondesign.com/build/startup/#v0

full_steps_per_rotation: 200 # Set to 400 for 0.9° degree stepper motor, 200 is for 1.8° stepper motors

uart_pin: gpio9
tx_pin: gpio8
uart_address: 0
interpolate: False
run_current: 0.742
you need to calculate the run_current value using the equation (rated_motor_current * 0.707 = Maximum_run_current) start with a value that is about 60%-70% of your maximum value.
sense_resistor: 0.110
stealthchop_threshold: 0 # Set to 999999 to turn stealthchop on, and 0 to use spreadcycle
diag_pin: ^gpio4 # YOU NEED TO JUMP THIS DIAG PIN ON YOUR BOARD FOR SENSORLESS HOMING TO WORK
driver_SGTHRS: 150 # this is set to 255 which is the MAX sensitivity for sensorless homing, you will need to tune this later
