To make a very long story short, I am missing the linear motion (X axis) part of my InMotion CNC. I have the plates for the X, but not the rails or ball screw. Does any one know where I can purchase the missing parts? It has become clear I am never going to get them through InMotion/XZeroCNC :-(.

The kit I ordered:
4X4: LC 4X4; Y Axis: 8" / 4 Short Bearing; Z Axis: 8 inch Travel 3/4 inch 20mm; Ballscrew Upgrade: 2510;
