I'm a bad bad boy, according to the advice about the USB cable and the power cables!!
I use a 10' USB cord, and it's run along the same channel as a bunch of stuff, including my computer, a radio, a fan, a heater, and a battery charger, as well as the power cord for the machine itself.
The machine works perfectly, with no glitches
Now if I could say the same for meshcam, I would be a happy camper.
