@dc42 David, so after many months of trying to get first a Laser and now a Magnetic sensor working.. I FINALLY HAVE IT WORKING! YAY. The sensor I got had a cracked piece of plastic not letting it tension the filament. The Installation guide should ensure there is tension on the filament before proceeding.
But to the reason i am posting here. Did the "post Script" ability every get implemented ? Like a Prusa I would like to allow it to do a specific action upon detection.
