Lightburn + Creality Falcon CR Cutting Off Bottoms of Image/Text


Both my text and .png files are being cutoff at the bottom of each. Brand new machine. Updated firmware. Set overscan boundary to 10%. Machine is level. Still facing issue. Any help is appreciated

I’m going to guess that it’s because you’re using center job origin in combination with current position. Try moving your job origin point to lower left and see what it does. Enable cut selected graphics and use selection origin switches.

You’re right. I didn’t look closely at his photos. Good catch.

Thank you so much for your reply. I tightened the belt, and…problem solved!!
