It looks like the tuning issue may have resolved some of what you were seeing.
Some of what you’re seeing is also expected behavior, like the dots where the scores overlap. There are a couple of workaround available.
One option is to rasterize the circles and engrave them instead of scoring them. This is frequently a trade off with time.
I also think some of the print results problems you’ve seen are related to an issue with our software with the number of individual images or shapes in your files. I recommend the one of the following options:
Rasterize any engraves or scores
Break your print into segments and reducing the number of shapes or images you print at once
When you upload your file to the Glowforge app, each color and each bitmap will become a separate print step. Divide your design into more steps by changing some of the portions of the vector design to be different colors.
Click on a step and choose “Ignore.” Repeat this to ignore all the steps but one, and then press “Print.”
When the print finishes, leave your material in place.
Set the step you printed to “Ignore” and print another step.
Continue ignoring and printing until you’ve finished.
I’m sorry for the inconvenience.
Please let me know if you have any additional questions, or any other print results you’d like me to look at.
