Ok so i'm fairly new to 3d printer and i rencently upgrade my mother board (MKS Robin Nano v3.1) with klipper, but i have some issue, when i'm trying to home all axes they go the right way for the endstop, but after they touch it the X & Y axes will got right at the end without stoping.
My printer is 230x230x240 mm and this is my printer.cfg setting.

Ps : i think that the probleme can come from my driver, I have TMC2225 driver and the mother board was deliver with the UART jumper on, and i diden't change it
Ps2: I don't know what the hell is ( UART SPI & STEP/DIR ) xD

Can someone help me ? thanks

Please share your complete config, I assume you missed the tmc section

#

What your printer should do

home x
home y
move your head to 100:100
home z

#

I guess as you missed the tmc section the stepper is not configured for 16 microsteps and therefor moves far more than the 100 mm

#

You could easily check that by

G28 X
G0 X10
That should move the head by 10 mm

Youer tmc2225 is equal to a tmc2208 so add that

#

Like always with that boards no schematic

i need to add this block ?
[tmc2208 stepper_x]

#

but i change the jumper to the STEP/DIR like my old board

#

do i need to change it back to UART ?

Without docs I am out of clue

#

You normally need STEP/DIR/ENABLE for the move signals and hart pin for the tmc vomunication
