First off is your width, Engraving moves side to side, and the laser head needs some space to speed up and slow down. How much width that turns into depends on how fast you’re going – just like in a car, you the laser head needs more space to “brake” when it’s going faster. That means that the maximum width of an engraving will change depending on the speed you’re using. Someone broke down maximum engraving width by speed somewhere, let me see if I can find it.
Ah, @jacobturner, among others.
OK that’s problem #1. Your design will likely need to be resized.
Problem #2 is your height, that’s coming right up.
