I know what my first 2 projects will be.
I am going to make a CNC platform for sewing embroidery using my el-cheapo black friday sewing machine. I should be able to do this quite easily with my smoothieboard. The only tough part I think will be software, generating the gcode. My sewing machine is very basic (I intentionally got a pure mechanical when I got it) so I should be able to swap out the built in motor with a stepper motor and each stitch is a nice even value in gcode, probably 100 indicating 100%.
The other project is I want a CNC feed for my drill press. I want to make a bunch of openstructures compatible wooden beams. That would mean drilling a LOT of holes, so I think that the drill press shall be automated to do that for me. I can code up something to kick out the gcode for that in a big hurry, very simple.
Does somebody want to borrow a couple of really cute kids for a few hours so I can concentrate on making robots that can make stuff? I can't yet incorporate them into the process.
