Homebrew PCBs

Don't go too small. Most of the cost goes in the bearings, motors, 
electronics, spindle etc. Increasing the length of the rails and 
screws/belt doesn't add much to the overall cost.

I know precisely the largest PCB's I have any intention of ever making, at my level of design and production, so I will scale the machine to precisely that purpose, and I will get outstanding results for small money.
