It’s possible, but I don’t think it’s actually a hardware issue…rather just a limitation. The engrave of course happens one horizontal line at a time. With the slanted font, the only way the machine can draw the slanted or curved lines is by shifting each horizontal line over a little bit. This results in being able to see the stair steps. I don’t notice any waviness overall in the images and haven’t had any issue with other projects I’ve done.
I think the difference in rotation helps because of the angle of the slanted lines. It’s hard to explain without drawing…so I took to the whiteboard.
Imagine the green is the path to engrave for the first leg of the ‘N’ while the red is the actual lines drawn by the laser. When that leg is oriented such that the lines to draw it are longer, there are fewer lines available to accomodate the slant. So you get larger stair steps. When the line is more vertically oriented, the actual raster lines are shorter and there are a lot more of them. Resulting in many more stair steps and thus the steps being less noticeable.
