Thanks for taking the time to make this tutorial! What is the point of changing the scan angle to -180? Isn't that same as leaving it at 0 angle since it engraves both directions (i.e. bi-direction fill)?
I'm confused by how this works when the tumbler has two different circumferences? It looked like you made your first test at the top and then the second at the bottom how can these lines be the same if the circumference is different?
