    ok i built this mpcnc router, very fun project, thanx guys.
    heres my problem, (using ramps 1.4) i added a laser to pin 44, got it working good.

    but now i want to setup a relay also to shut of my dremel after a long cut automatically so i dont haveto b there. but to do so i need to use the 12v fan output, but my pins are remapped to pin 44.
    now i read somewhere that u have setting in there already setup for lasers with the m05 commands and such on the servo pins or something. if i could use those i cud have my laser going plus my relay (with the m106 command) without haveing to redo it each time.

    but i cant find any documentation on useing that laser feature or how to get those sevo pins working for it, any ways u can help?

    or another way of doing it

    You can not leave your machine unattended. Fires happen in seconds.
