Re: etching/engraving PCB via a small CNC

Take a look at the "brute" by John Kleinbauer. He has a pcb router
design that is economical and quick to put together with off the
shelf part using hand tools. Here is the link:

The driver boards for a router are available at several sources.
Xylotex makes a nice plug and play that drives readily available
bipolar stepper motors.

Below is a link for brand new bipolar steppermotors:

I use the 276 inch ounce on my mini-mill. The smaller ones there
would work fine for a small router of Kleinbauers design.
