Lead machine losing work coordinates

I have a newly built Lead Machine 1515 that has started to lose its work coordinates. My first few simple single pass cuts worked fine. Now I’m trying to run a multi pass cut on 19mm material and after the first few cuts the machine is losing its position and setting down a few inches off. I believe it’s mostly the x (left and right) position that’s off. At first I thought it may have been the long usb cable I bought but after going back to the original the problem persists. Anyone else have this issue or have any recommendations?
