Hi Tom,
Your comments have me worried. I have assumed that the alignment of the machine was tied to the bed camera, and I have seen a few comments stating that the lid is warped or the side rails are… or comments that the “fisheye” wide angle distorts towards the edges. Do you know how much misalignment you have? I was planning on running a test. I have a wide format injet printer, I thought I would print a radiating pattern of simple shapes using the printer and a ruler to set scale. I would print it and then use the trace to see how well the machine duplicates the expected lines/shape.
I was hoping to quantify the distortion. I may have missed it has Glowforge output an expected distortion range?
