I am still learning about what my Glowforge can do. I’ve done some engraving and had some weird results. I want to use the variable power method, but when doing test strips on wood, the color didn’t seem to fade linearly as expected. That may have been partially due to the masking, but there even seemed to be an S-curve in the color instead of a linear fade. I decided to put that on the back burner, but then this weekend I was testing engraves in acrylic and realized that there really is something off here. Here is the image that I gave the Glowforge;
it’s a straight fade from black to white. The result was not a smooth fade in depth. Investigating further, I found that the most obvious errors occur between 55% and 70% power. Here are the results of engraving the previous image repeated 5 times in the same place (taking breaks in-between to cool the plastic). With each engrave, the errors became more apparent.
Thanks for any help,
PS I saw some discussions about the grain and banding that is visible in engraves. was there ever a solution to that?
Also, if this post is beyond the manual, feel free to move it there.
