I want to use a solenoid on the M7 mist function and I am not sure how to set this up.
I have a 12v solenoid.
I use Mach3 and UC100.

Do I need a relay switch off pin 6 on the G540 and then to the solenoid or do I hook the solenoid directly to the G540, pin 6 and output 2?
Any help would be appreciated.
