I am new to the laser cutting business. I have a Yaro 60 W laser engraver with a Ruida controller. I am using it to cut glass, specifically coatings on glass cylinders, so I am using a rotary attachment. I create my art in Photoshop and bring it in at the specific dimensions required to wrap around the cylinder exactly once. I have set the object diameter in the rotary setup window in Lightburn and it appears on the workspace properly. But when I cut, the length (x axis) is correct, but the image is distorted in the y axis (the diameter) significantly resulting in image overlapping by as much as 3/4 of the circumference.
As an experiment I brought in a graphic that was exactly square at the dimensions of the circumference of the cylinder. The resulting etch was the correct size on the x axis, but grossly distended on the y axis. I am at a loss as to why. Please forgive my newbieness if the answer is easy or obvious. Any help is appreciated.
