Dimensions not Cut Correct

Hello,
I’m having an issue with a Sculpfun S30 Pro Max. When I want to cut out a square say 4"x4" I get a 4" wide but a 2.5" Height. How do I correct this?

Have you calibrated your stepper motors?

Most likely your steps/mm values are not correct. Make sure both axis are set to 80 steps/mm. You can do this via the console or using the machine settings in LightBurn. Some details:

Perhaps you have inadvertently turned on Rotary Mode?

The LightBurn switch is in the Laser window, immediately under the Home button, just one finger fumble away.
