Hi, I've a problem, when I type M666 in Pronterface I haven't any answer. So when I want to change endstop offsets, it does nothing. Thanks if you have an idea
It's not supposed to reply - it *SETS* values. Use M503 to see what they are . . . Note also that values to M666 *MUST* be negative, or they are ignored. Marlin is smart enough to not try to power through your endstops . . .
