Here are the relevant config values.
#define X_PROBE_OFFSET_FROM_EXTRUDER 52 // X offset: -left [of the nozzle] +right
#define Y_PROBE_OFFSET_FROM_EXTRUDER 6 // Y offset: -front [of the nozzle] +behind
#define Z_PROBE_OFFSET_FROM_EXTRUDER -1.70 // Z offset: -below [the nozzle] (always negative!)
I set them based on my own measurements. Everything works great when using the 1st hotend. Things only go pear shaped when using the 2nd hot end.
At this point, I suspect a Marlin bug. But I have not experimented enough to know for sure. Certainly getting farther by turning off ABL is a sign
Printer will print perfect...
