    So, I was thinking about something and was wondering if anyone else had similar thoughts..


    How hard (or even possible) would it be to wire a relay in between the ramps and router so it responds to M3 and M5 codes? Clearly with a 611 or similar an M4 or S codes are usless.




    Just on and off, should be no problem. Speed control is a whole different ballgame.



    If you want a turnkey solution, this guy is pretty great. I have one and Barry has one (I think it was Barry).


    I don’t have it on my low rider, just because I’m lazy, and it’s kind of big. But it worked great on the MPCNC.
