A cheap & easy to build CNC Machine for drilling PCBs

After etching my first Printed Circuit Board (PCB), it immediately became clear that drilling the holes was going to be a problem. Not only are there a lot of holes in most PCBs, but the drill bits are so small that any horizontal movement results in the bit breaking....

I’ve been trying to come up with a better method then skate bearings, which my current CNC machine uses, and I think I might be on to something..

One problem with my first CNC machine is that accuracy isn’t that great, which is caused, in part at least, by the way the axis slide back and forth. Another issue is the z-axis not being supported...

Over the summer I designed a small CNC machine for dilling PCBs. The design has been finalized and I have begun building it.
