So this is an experiment to see how quick/easy something useful could be built from Contraptor. I've gotten several emails regarding possibility of building a small CNC machine from Contraptor, so looks like this might be a good test. I had previously built the mini-router and it worked, but it was pretty cumbersome to assemble and adjust, hence another attempt.
Yesterday I did this napkin drawing.
A CNC machine can be built in many different ways, this is just one of them: fixed gantry, moving table on X (or is it Y?), moving head on Y. Entire Y stage moves in Z.
Then I spent about 3 hours in Sketchup building the structure and some motion assemblies. The Sketchup file is on 3D warehouse, it is draft and unfinished: http://sketchup.google.com/3dwarehouse/search?q=contraptor+mini+CNC I think I'll change a few things and finish the design, hopefully today.
