M8 while running

Is there a way to do M8 turn on air with machine already running say if you realize you need it but can’t start over. I tried typing M8 in console but didn’t work. this is for Sculpfun S30.

I’m not certain it will work but try pausing first, then issue M8 in Console, then resume.

Tried that no luck thanks

It was a longshot. In that case I don’t think there’s any way to achieve this.

No, that’s not possible. grbl doesn’t support override commands like this.
