I have an open case with USCUTTER where I have completely described the issue. The only thing I can think of due to the randomness of the lines is static. I took the arm screw out from the roller bar holder and grounded the machine to the stand. I took a dremel and ground off all of the paint and ground the machine to the stand. I have thorougly tested the ohms resistance between these two pieces including the roller screws and roller bars. Everything is grounded and I even took the plastic bar holder off and made sure the screws were contacting the rollers. Everything is grounded. Settings all appear perfect according to the threads I have read and support articles I have read through. The only thing I can think of is that I am getting some rogue current from sitting on thicker carpet. The signal is being completely passed from the computer as watched through the hex line monitor. After the signal is sent to the cutter it appears to keep cutting, but then the cutter strays across at an angle and then continues cutting for a bit before returning to the origin. I have tried connecting via USB to no avail. The cutter would actually stop 1/2 way through a cut. I am not sure where to go from here. I will update if/when I hear back from support.
