    I've just completed the wiring section of my workbee 1010 screw build and was playing around with the movement on all of the axis and all of my micro usb switches are turning off usb when they hit. Is that correct or is it just supposed to stop movement? I've looked up a bunch of videos and forums and they all seem to reference different machines or limit switches. On each switch, I have the red going to the NO and the black to C. There are only 2 wires in the kit that I got for the limit switches and when they go to the Blackbox, they go into the ground (black) and V+ (red). That is what I got out of watching a few mixes of videos but the USB just full on shuts down when the limiter is hit. The USB will not connect again until I manually move the axis off of the limiter.

    I even got 2 computer shut downs because of it and had to do a hard restart. Not sure if that plays a roll in anything but I thought it was strange a USB disconnect can have such power over the computer.

    Keeping an eye on this because I hopefully can get it fixed ASAP as I want to start cutting soon

    That indicates the limits are wired wrong:
    Wire as shown in the documentation: OpenBuilds BlackBox 4X Documentation using 2 wires only. (sometimes people wire it wrong and short V+ to GND with the switch, instead of Signal. V+ gives power to active limits like Xtension Limits, Inductive sensors etc. Do not wire it when using plain switches.

    Or upgrade to Xtension Limit Switch Kit they support 3 wire mode

    That was it. I didn't come across that info anywhere for some reason. I didn't want to just start moving the wires around due to the hard reset it did on my laptop. Thank you very much.
