Adventures in wobbly cartesian robots, Introduction

I've always been fascinated with automatic manufacturing and have been avidly following the homebrew 3D printing for many years.  I've always been daunted by the ~$1,000-2,000 cost of getting into the space, along with not having anywhere to work on such a thing.  (I have five kids and until recently a very small house.)

Last summer, we expanded our home and for the first time in many years I had access to a proper garage. I therefore began a project to build a CNC router.  I had considered additive processes (3d printing) and subtractive processes (machining/milling) and was conflicted for quite a while as to which would be a better place to start.  After extensively reviewing the different options out there I settled on an MDF framed, router based mill as being affordable and buildable with the tools I had at my disposal.

My goals with this project have been to boostrap from highly inaccurate hand tools (power drills, a tiny cheap table saw, wrenches and the like) to a device that lets me cut with < 1mm accuracy in materials up to the hardness of aluminium.

  1. Another option is to first make mock-up components in either foamboard or cardboard and duct/masking tape.
