Whereas our drilling machine had a simple peck-and-drill motion, and there were no lateral forces to contend with, Justin is looking to mill PCBs with a dremel or similar drilling head, which means the chassis needs to be able to resist some twisting forces on the uprights.
As a quick-and-dirty prototype, we put together an MDF-based frame and used drawer runners from an earlier prototype of our own drilling machine.
Justin is going for a moving gantry system, rather than a moving bed for the y-axis. We ran out of drawer slide rails to finish the x-axis but the frame so far looks very promising!
