Centering nozzle for print and homing | Marlin | ABL | Senroless Homing

[sebbo111]

Hello all,

i upgraded my sidewinder X1 with an SKR 1.4 tubro board, TMC 2209 stepper driver and an bl touch + sensorless homing. So far i couldn't see any bigger issues, but when i use homing or try to print something, the start position/center are not really centered. It seems the bl touch is nearly more centered as the nozzle (but also not fully). As i could not really find an answer via google and playing around with some values ended up in like nothing changed or crashing into the bed, hopefully someone could give me a tip.

My current marlin settings are:

// The size of the print bed
#defineX_BED_SIZE310
#defineY_BED_SIZE310

// Travel limits (mm) after homing, corresponding to endstop positions.
#defineX_MIN_POS0
#defineY_MIN_POS0
#defineZ_MIN_POS0
#defineX_MAX_POSX_BED_SIZE
#defineY_MAX_POSY_BED_SIZE
#defineZ_MAX_POS400


// Manually set the home position. Leave these undefined for automatic settings.
//#define MANUAL_X_HOME_POS 0
//#define MANUAL_Y_HOME_POS 0
//#define MANUAL_Z_HOME_POS 0



Thank you and greetings,
Sebastian
