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 multi-point levelling.
* If you chemically etch, you deal with nasty chemicals. And even if you're fine with that, you're prone to over-etch, 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 trace-and-space 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 error-prone.
* 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 one-off prototypes and tests. For anything more, go to China.
* I haven't done a double-sided 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.
