call me asap. ill pm you my number. i have a fix that graphtec wont tell you about. trust me. i know WHY your problem is happening. it cost me $5k to figure it out.
by $5k, i mean i put a graphtec fc8000 through the WALL because they couldnt tell me how to fix it. i bought another, and realized WTF was going on. and their tech support is completely stupid as to what the factory settings are the caused your problem.
ps, your y or x axis is off, and its due to your laser intensity settings. probably using laminated material. god i know everything about that stupid cutter.
pretty sad they dont.
