Hi everyone

I'm new to grbl so please bare with me.... still getting my head around the software and adruino!

This is the first basic question I have so far, many more to come I'm sure...

I want to M3 (Motor start) command to turn on a relay in my arduino which I think is spindle enable, can this pin drive an SS relay directly or do I need so kind on interface?
Don't want speed control just on - off relay.

Thanks guys

I do control my Solid State Relay with the motor on/off pin from the Arduino Uno and it works perfectly.
