I've set up my Grid compensation at 13 X 13. I get all my points, I save with M374, but then when I recall grid with G31, It gives me this:
X0 A45.00 B3.51 C3.56 D3.45 E2.98
X1 A2.61 B2.63 C2.68 D2.44 E0.93
X2 A1.28 B1.85 C2.23 D2.44 E2.49
X3 A2.88 B3.30 C2.76 D2.35 E2.32
X4 A2.20 B1.02 C0.23 D1.42 E2.12
I've looked at the file, and it starts with 45, and then lists all the points down the list, no letters or anything. Did something go awry when saving, is there an example file I can look at? Any help would be appreciated. I'm doing this on a very large printer, and it would save me some time to just write out anything that is missing.
