    Default Fadal 4th axis brake question

    So I added a VH-65 to my VMC 20. I ended up having to add the inhibit board that turns the servo off when the brake is on.

    So my question is: I assume the brake should be on when machining? The brake can be turned on/off with M60/61

    I believe there is an Auto brake parameter that will turn the brake on after 75 seconds. Seems like you would want the brake on right before machining.

    I was going to have the post processor modified to add the M codes before and after any A axis moves ie
    M61 A90 M60

    Any reason why I shouldn’t do this?

    Thanks

    I don't think you need the M61's. We just use M60 after every A-Axis move. The brake automatically releases when the control reads the next A-Axis move.
    But yeah we use M60 after every A-Axis move. Never used M61 within the program and never had any problems.

    FWIW,We have had ours for a long, time. The only time we use m60 is for milling. It does fine for drilling and tapping just using A.
