Just a note of question. Depending if the mini IR is mounted on one of the sides (X) or the front/back (Y) of the extruder will determine if you need to set Y_PROBE_OFFSET_FROM_EXTRUDER or X_PROBE_OFFSET_FROM_EXTRUDER or maybe a little of both if the IR isn't in direct line of the extruder hot end tip. I guess if the IR is mounted on the right of the extruder and foward of the center of the extruder hot end tip, then you might have to adjust both correct? Maybe I'm overthinking it. Finally, just for clarification sake (and I might be more tired tonight than I want to admit) when you set the Y probe offset to -25 are you saying the probe is 25 mm in front of the extruder or behind? I would assume in front since it is saying (from what I understand) that where the current position of the tip is that the probe is 25 mm greater than that Y value (Hotend - Probe). If it was in back, then it would be a positive number. Sorry for the potentially obvious questions, but wanted to make sure I understand the requirements for making these settings.
