    Default FH-6800 switch off Air Blast at spindle stop

    Machine - MAZATECH FH-6800
    Control - MAZATROL 640M

    Does anyone know if there is a way to switch off the through spindle air blast when the spindle stops?

    When using through spindle coolant there is an air blast at coolant stop/spindle stop. I understand there is good reason for this, but the part I am making requires lots of peck drilling and spindle/coolant stops to clear chips from the hole and a big coolant mist cloud forms and gets worse with every peck.

    I have found an M code that seems like it would switch the Air Blast on but not a code to switch it off 🙄 -
    M45: Air coolant blow ON(coolant stop: M09)

    Ideally I'd like to program the air blast to be switched off for peck drilling and back on for normal machining but any suggestions/M codes/parameters etc... would be much appreciated! Thanks!
