Automatic Vacuum Switch

Hello everyone. I’m looking into switching my vacuum system automatically on and off. I’m thinking of this: I need to know if Carbide Motion would allow me to do this. I read that M7, M8 and M9 are accepted but ignored. Could I use M3 (spindle on) and M5 (spindle stop) for this?. If so, is there any danger to the spindle?. If it is possible to do it another way, say with M10 and M11 (vacuum on and off) what pins are used for this on the Arduino?.
