[BUG] Weird endstop issues on mega x with ABL

[JamesSeager]

When auto bed leveling, possibly as I have installed a larger carriage, the carriage hits the frame of the printer. This is additionally problematic as my bltouch probe is positioned on the right side of the carriage and then moves off of the print surface. Please may you guide me through adjusting the limits in the firmware.

Thanks in advance,
James

If your sensor is in a different place, you can change not only the Z, but also the X and Y offset with the Gcode M851. (See: https://marlinfw.org/docs/gcode/M851.html )
