Laser Cutter - Engraving

OK, so I did some engraving on the laser cutter this evening but finding it tricky to achieve different shades of engraving on plywood.

I’d like to maybe have 3 different shades from very dark to light and not sure exactly how to adjust power/speed/frequency to achieve this.

Any people out there who’ve done this and have some good settings?

Ruby has better settings for that.

You can defocus the laser slightly to get it darker. But generally you would adjust the speed to to see what works best.


I saw an interesting video on fine tuning power vs speed on materials using a grid design, it was for cutting rather than engaging but can’t see why you couldn’t use the same process.

Actually while looking for the cutting video, I found an engraving video… they’re not using tool control or Ruby, but I’m sure you can figure it out


I think it’s either burnt or not burnt with a very fine line between them

Have you tried dithering the image?
