I'm using my Shapeoko 3 to dispense glue, and I control an external dispenser via the spindle control pins on the grbl board. When I send M3 or M5, the control signal changes immediately but there is a 2-second dwell. Can I get rid of the dwell so that I don't build up a blob of glue at start and end points? I've gotten around it so far by turning acceleration and rapid rates way up, but that's still not as clean as actually stopping and starting the flow for rapid moves.
