T3P3Tony, It works 😄 but only with M42 command, the M280 does nothing. Anyway I'd call it enough for me. One more question about M42's "Use M42 Px Sy to set pin x to value y. The S field may be in the range 0..1 or 0..255" - the value of "S" corresponds to pulse width in microseconds or something other?
