The cheap chinese ones only do raster(something to do with the

extra work (at least of multiple offset passes) also I don't think it
would make a wide enough break in a resist to give good access to the

this groups for.
Good idea that about using the engraver to do serial nos. on the
board, take that to the next level instead of screen printing a
component overlay why not engrave it I'm certainly going to give it a try.
