    Nice project Chaz.

    Iím sure you know this stuff but when I did my box I followed a few guidelines and have not had any problems or false estops:
    Power lines separate from logic lines
    24V logic wherever possible (not 5V)
    Star Earth point
    Drivers in a row not column so heat went up and away
    VFD tucked up in the top left corner so air came in through the left side of the panel and straight out the top (if your VFD fan draws from the left side)
    DIN rail power supply not the generic ebay power supply (just for ease of mounting, not sure if there is any electrical principle difference)
    Ferrules on each cable

    Final tip is give your fingers room to get in to insert cables and space for the screwdriver.

    Making progress, wired up most of the controls, quick test run with some existing / included code. Axis are not calibration yet (distance etc), wanted to check movement. It sounds like the X belt is fouling, will need to sort.
