Not getting a 5 in square

Hi I have A hl-1060 100w co2 laser w/ruida when I try ro burn a 127.5mm square I get a rectangle that measures 127.5 horizontal and 80.1 vertical I have tried to adjust the x and y parameters in the machine settings but nothing is working…Please help

Show us what you have for settings and tell us what you have adjusted. We can go from there.

If it’s that far off on the vertical, and “nothing is changing”, chances are high that you’ve left your rotary setting on.
