So from the day this GF was designed, who came up with the 12 x 20 sheet size and a cutting window of 10 3/4 x 18 1/2ish. There is so much waste of material. Would it have cost that much more to use the full cutting area. Make the machine 1" deeper and 1 1/2" wider. If the cost increase was only about 500 to 1000 more. You still will have sold plenty more.
Also, from day one using this laser there seems to be a sweetspot that the laser on 1000/full cuts through almost anything I put in it, but to the contrary a spot close the home position where nothing gets cut thru. So many sheets partial sheets have been wasted because of poor cutting area. The GF has been cleaned several time before and after this poor cutting and still it underperforms.
