Box sides become distorted the bigger the box

I drew two boxes and they both appear to swell on the sides and cave in at the top when they print. Largest box is 76mm x 158mm set to LINE mode.

I tried opening a new window and drawing a new box but it does the same thing. I have checked the settings (at least the ones I know of), ensured focus and plate is flat to the surface. Any help is appreciated. Running Monport 60w MOPA Fiber Laser, latest version of LightBurn.

Congratulations and welcome to the forum.

Did you import the lens/machine configuration file that was supplied with your machine?

On mine it’s markcfg7 and you import early in the device creation.

Hi. Yes I did. Went back and doubled checked just in case.
