Re: How to start levelling from scratch?

So your probe offsets are X-25 Y-50, to the left and in front of the nozzle.
The probe can reach X min Y min ok , and X max-25, Y max-50 ok

Try

#if ENABLED(AUTO_BED_LEVELING_3POINT) || ENABLED(AUTO_BED_LEVELING_UBL)
#define PROBE_PT_1_X 10
#define PROBE_PT_1_Y 10
#define PROBE_PT_2_X 175
#define PROBE_PT_2_Y 100
#define PROBE_PT_3_X 10
#define PROBE_PT_3_Y 150
#endif


This should probe 10mm from the front left front right and rear left of the bed, if my math is correct :)
