I was busy this weekend doing some material testing with the E2. I have a large scrap pile in my wood shop, and being a borderline hoarder, I have other items laying around that were screaming “see if you can laser on me”. So I thought I would share my results with the community. Hopefully, you guys will find this useful, even if the pictures aren’t great. I have a few questions about the testing process and how to apply the results.
Cherry wood sanded to 320:
South African Mahogany sanded to 320:
Hard Maple, sanded to 320
Absolute Black granite floor tile, polished side:
For the slate and granite I used the settings I found in the forum for slate engraving on the 4watt E1. It engraved the slate nicely, but the color change wasn’t drastic so it was a little hard to see. The granite engraved decently, but the edges seemed fractured in some places. I guess you could color fill the slate engraving to help it stand out better. If I was going to engrave on the granite I think I would stick to vector stuff. I love the way the hardwoods engraved, especially the SA mahogany.
So as far as interpreting the results, these were all done using a raster engrave setting. Do the shading variations in the test correlate to levels I set the power if I am doing vector cut and fills? Like if I want a semi dark fill I would set the % of power based on what I see in the test grid?
Next round of testing will be purple heart, Baltic birch plywood, North American clear pine, brick. I also want to do some vector testing on the slate and granite.
