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!
Not only your contents but also the way you present the issue is awesome. Particularly this one is articulating the sense of the discussion. Your word power is awesome. Keep it up.
