(update: link to 'ible replaces waffle about insufficient info. yay.)
The current iteration of this little CNC mill works well enough to produce an eye-candy demo video:
Minamil: a minimal CNC mill
First there was #CDCNC, a highly-constrained just-barely-functional one-off toy built by improvisation with found junk with simple tools.
Here I'm developing an idea that came from thinking about whether or not there is any space between a dumb stunt like CDCNC and a commercially (i.e. efficiently) produced entry level CNC mill. Early results seem encouraging.
In contrast to CDCNC, this is about reproducibility from a simple BoM, economical access to laser cutting, and instructions for building your own sub-mini CNC mill.
Next there may be #"Desk Accessory" CNC Milling Machine
