Fixed Gantry CNC Router with Old Industrial Supplies

I got lucky enough to purchase aluminum extrusions and linear motion components (and nuts/bolts/etc) at scrap metal prices when a bunch of industrial automation equipment was decommissioned. The only problem is that the aluminum extrusions are not metric sizes... they are the 1.5"x3" 80/20 series. It has presented a few challenges but nothing too bad.
