Lately I've been building a homemade CNC platform intending to be a light mill / router / printer / laser cutter / fill in the blank. To start its setup to be a CNC Router, which has started to make some parts for itself to increase stiffness. I've made it to the first milestone, a running machine I can control that cuts aluminum to reasonable tolerances.
I put a short video on You Tube of it doing the fun task of sketching a SoftPro Logo using a SoftPro pen.
