Engraving Copper for DEPTH with a 20W Fiber Laser

Here's an attempt to find some settings on my 20w laser that will engrave deeply in copper. Marking times and settings are included as well as verification of depth with an indicator. Results were pretty good.

Thank you for doing the testing for this.

is it true to say that the edges are very sharp and barely not frayed? If yes: the laser cuts / marks down straight and even with several passes doesn't fray the edges? Your method of getting knowledge with laser settings in different materials is exemplary. thank you very much.

Hi thanks for your videos. Do you have a conversion factor from a 20w or 30w to 50w to give me a starting point as I’m unable to find many settings for 50w fibre laser this on the net. Cheers

You know the indicator is not linear when it is at a 45 degree angle to the work?
