Works ok. Sometimes…

    Any idea why I’m getting the distortion on the x axis? Worked fine before rotary. Rotary is on y axis

    There is a formula for the ratio for design graphics on a rotary due to the artwork being on a curved surface. Sadly I can not remember it. You can probably get and it on the Lightburn forum if no one else chimes in.

    It could also be that your y rotary axis calibration is off a bit .

    A and T shows the distortion well, look closer: Looks more like the way he has the cup mounted allows so axial movement while rotating. Static 2-wheel rotator I assume? (Chuck would be better)

    It is a static 2 wheel rotary, I’m having trouble wrapping my head around the rotary causing it, the text is lengthwise on the cup so parallel to the x axis. It seems like I have drift on the x axis the way the “583” numbers are blown out. Maybe I should rotate the rotary 90 degrees and try perpendicular to the x axis?

    As the static spins the cup, the cup isnt really constrained well. It moves along its length as it rotates. That style of rotary is notorious

    This makes perfect sense to me.

    thank you
