How to include a dwell after M3?

Hi, kind of a newby question…
Running a GRBL machine.
How do I include a dwell after turning on the spindle?
My dwell macro contains ‘G4 P4’ but this doesn’t show up in the generated gcode.
If I put G4 P4 in the header it precedes M3, so it’s of no use…

can you add it to your spindle speed macro?

Thanks for the quick response.
That works indeed, now I won’t need to manually add it every time… :wink:
