    Default new build, have some basic questions

    Thanks for looking.
    Here is a small build I'm working on. 1030 extrusion over 2" square tubing. Avidcnc rack and pinion, pre fabed z. Nema 34s on x and y. Triple stack 23 on z. 3kw main spindle. 5kw secondary.

    Any questions or comments are welcome.

    My input amperage on 115v is approx 36amps with all the power sources added up. Should I be running a low amp on off switch to a relay to power them up? Even if I run 220 to them I'm over 15amps. Where should the breaker go? Thanks for any input.

    Control panel is just that.
    e-stop, system arm, vacuum release, spindle speed control for both spindles, etc.
    Lunchbreak is the name of the business its being built for.

    You don't appear to have a Disconnect on the Main Power entering the cabinet.

    The Main supply after the Disconnect should go to the Breakers, and then to each device you want to protect, The VFD Drives normally would have a contactor to turn the Main Power supply On / Off

    Where do you live that you have 115v /220v supply?

    3kw spindle will be more that15A @220v, what is the amp rating of the spindle 3Kw on 120v will run very poorly, and I would not recommend to do this if you have a 220v supply
