Third successful aluminum run

I milled the third of four plates that I'll need for upgrading the CNC router to use the larger extrusions. I milled with the Niagara bit, 300 mm/minute feed rate, and .2mm per pass. At some point it lost a few steps doing the final contour cut. It also had to be cut down to 7.25mm, and even then didn't make it all the way through --- even though the aluminum is only 6.25mm thick.

This run was the first aluminum run with the X-Controller.
