    I am using Fusion360 CAD and Fusion360 Openbuilds Grbl Post Processor and I am having a problem tuning the vacuum on and off. Grbl needs an M8 for on and M9 for off, but the Post processor will only give me an M7.

    Fusion CAD manufacture has several; vacuum (coolant) setting (mist, air, flood etc.) but seems to default to mist - and this seems most compatible. But all the settings post an M7.

    any solutions?

    Select flood and it will generate an M8. Make sure you have "has coolant" enabled in the post processor settings.

    flood = M8
    mist = M7
    flood and mist = M7 M8

    grbl needs a special build for M7


    Code:
    (Made in : Autodesk CAM Post Processor)
(G-Code optimized for Grbl 1.1 / BlackBox controller)
(OpenBuilds CNC : GRBL/BlackBox)
(Post-Processor : OpenbuildsFusion360PostGrbl.cps V1.0.30)
(Units = inch)

(Drawing name : pegboard v2)
(Program Name : 1001)

(1 Operation :)
(1 : Holes)
(  Work Coordinate System : G54)
(  Tool 3: Flat End Mill 3 Flutes, Diam = 0.25inch, Len = 1.25inch)
(  Spindle : RPM = 17000)
(  Machining time : 8 min 44 sec)

G90 G94 G17
G20


(Operation 1 of 1 : Holes)
G54
(This relies on homing, see https://openbuilds.com/search/127200199/?q=G53+fusion )
G53 G0 Z-0.3937
G0 X5.7558 Y-6.0733
