How is it at making printed circuit boards? This is my first try, and it's not that bad. Here are some answers to the obvious questions:

* wegstr.com

* Did I say "speed vs time"?! I meant "quality vs time". Or maybe "price vs time". As they say, "Price, quality, time: choose two."

* Yes, I know about Othermill/Bantam. I wanted to try this one. Also, apparently Bantam doesn't do multipoint levelling.

* If you chemically etch, you deal with nasty chemicals. And even if you're fine with that, you're prone to overetch, and then you still have to drill. This can "etch", and drill, and cut slots and various board shapes.

* It seems like it can do 8 mil traceandspace but I wouldn't go lower than a space of 10 mil.

* I have no idea how long the bits last.

* I was conservative because I didn't know if the bits would break.

* The whole process is highly errorprone.

* It could take a day to make one board, as opposed to about a week for five from China. You can do solder mask. This is for oneoff prototypes and tests. For anything more, go to China.

* I haven't done a doublesided board with it. I'm not sure how to fixture it for alignment. One video from wegstr shows that they milled out a negative for the board in the XY table, pop it in, and engrave out the bottom side.
