Ideas

Making it modular

Much like Alexander Stepanenko has done for CNCs here:

This would allow extending to a multi purpose machine at a later stage. Examples of existing multi purpose machines are Diyouware[1] and Fabtotum Fabricator[2].

This means driving the X/Z directions by rotating two motors in same/opposite directions. The idea has been tested with good results[3].

The big win with this configuration is saving one motor (compare to current common designs that uses 2 motors for Z axis) and much easier build (thread and bearings replace threaded rod with nut).

There's nothing hindering us from also driving a Y axis with lines, like shown here:

Again, saving in a Y-axis belt and motor makes it an easier build. Using v-groove bearings and dynema line for driving all axes also takes down the unique part count really low.
