Hey guys long time fan of this site first time post. Im looking to build a small to medium size CNC machine that is capable of milling PC boards. This will more than likely be the only function required from the machine. I looked at a few machines especially the Mantis 9.1 (http://makeyourbot.org/mantis9-1) but the working area appears to be tiny.
So I have 2 issues im running into, it seems as though all the plans for a machine require CNC machined parts, if not from parts that make up the machine, the plans for the stepper controller boards can only be made.
Does anyone here have the ability to mill a set of boards using an open source layout so I can get the electronics portion running? I know I can buy controllers but im a student so naturally im strapped for cash. So building is the best option for me.
The second question is, what plans would you guys suggest for something with a decent working area that is easy to build, has enough precision for milling boards, and is cheap.
Thank you again guys for your time,
