m0540	Endstops Abort SD	Abort SD printing when an endstop is triggered.	thinkyhead	SDSUPPORT,SD_ABORT_ON_ENDSTOP_HIT	sdcard	M540	Requires `SDSUPPORT` and `SD_ABORT_ON_ENDSTOP_HIT`. Use `ENDSTOPS_ALWAYS_ON_DEFAULT` or [`M120`](/docs/gcode/M120.html) to ensure that endstops are enabled.	tag optional description values S false Whether (1) or not (0) to abort SD printing on endstop hit. tag type flag bool

Set whether SD printing should abort in the event of any endstop being triggered. This provides a fast way to abort a print in the event of mechanical failure such as loose couplings, lost steps, diverted axes, binding, etc., which lead to axes being very far out of position.
