i just added piezo probe to my tronxy x5s . nozzle homes about 20mm left of bed, thats normal position. when i try to probe the bed with nozzle it tries to probe in 0,0 coordinates. tried every setting that gives some offset or distance from edge, nothing works. any ideas?

Make sure that you set X_MIN_POS to a negative value. If the X home position is 20mm to the left of the bed then X_MIN_POS should be around -20 (you should measure the exact value to make sure). Once you've done this, do a "G28 X Y" (home only X and Y) followed by a "G0 X0 Y0" and ensure that the nozzle ends up just over the front-left corner of the bed. If not, adjust X_MIN_POS and Y_MIN_POS accordingly.

just tried that, nothing changed. still tries to probe the bed at physical 0,0. maybe it has to do something with UBL?
