Finishing path fails

Running a new project the roughing pass went just fine. I set up the finishing path, homed the machine, and reset the zero point. Within about a minute the mill was blazing through the outer material in a random path. I stopped the carve and the machine went back to the zero point, the problem is that the point it went back to was about 1 inch in the -Y from where the corner of the material is.
I have added a shielded data cable, I have separated the data from the power. This only happens occasionally and I can never predict when it will happen. I am getting seriously frustrated with this set up. I hope somebody has an idea of what is causing this.
