My research on small scaled mills have taken me in exciting new directions. You might have heard about the website, Instructables.com, well I just couldn't help myself from attempting to build my own cnc mills from these directions:

The author of this instructable mentions some things that might help us narrow down our search on what method of movement we want to use. First thing I learned from this instructable plan is that the drawer pull movement paired with screw will work, but print quality will be about average. We would lose accuracy when the drawer pull is fully extended it is less stable. Also this plan uses a dremel tool as the mode of carving, but as the author explains:
"The spindle is probably the most important part of the machine. If you buy something that has too much run out (movement in the shaft/bearings which makes your cutting tools “wobble”) you will have difficulty achieving any sort of accuracy. This is the mistake I made, I chose a Dremel 100. This is a great tool, don’t get me wrong, but it is made with a plastic housing, and it turns at 35,000 RPM so it has quite a bit of run-out."
This hands on learning and building of this machine I hope to learn valuable skills to bring to the cnc router/printer/scanner team.
