Show"N"Tell ( What you have made with your CNC machine.) / Re: My first attempts at laser engraving.

Hi Dave,
A moron like me managed it OK.
Its a standard 150mW diode laser from China mounted to the Z axis. You can draw any vector graphics on relatively dark colored, thin, materials and woods in the same way as engraving with a cutter but at a much, much lower feed rate (too fast and it doesn't mark the surface, too slow and it cuts right through thin stuff)
Although it cuts the dark vinyls well the edges of the cuts are slightly raised where the material has melted so only 'so so' for bumper stickers and the like (drag knife cutting of vinyls is better).
What do you need to know ?.
Tweakie.
