+ * M125: Store current position and move to parking position.
+ * Called on pause (by M25) to prevent material leaking onto the
+ * object. On resume (M24) the head will be moved back and the
+ * print will resume.
+ *
+ * When not actively SD printing, M125 simply moves to the park
+ * position and waits, resuming with a button click or M108.
