I just purchased a 2nd hand Epilog Helix 50W laser. Just setup with exhaust and air assist, and testing a file in Adobe Illustrator.

I have successfully cut MDF and plywood. I designed a file in AI to cut 3mm Acrylic, and the engraving was approx. 1" off on the x axis (see photo).
I rebooted the laser cutter, and sent the file again. But the mis-alignment occurred again.

Anyone have any idea what I am doing wrong? My AI file is properly aligned, with the vector as a .01 pt stroke, and the text converted to outlines with black fill and no stroke.
