Loose USB connection when running limit switch calibration

Hello all,

I finally got my X-carve together and am starting to run the calibrations. I had no problems up until the limit switch calibrations. When I go to run the calibration it jogs to the z-limit switch, engages it, and then I lose USB connection to the x-carve. If I take out the Phoenix connector after this happens the USB connection comes back. Any thoughts on why this is happening/how to fix it?

Thanks in advance.
