I’m puzzled by the calibration results I’m getting, and even more puzzled by the ‘confirmation test’ that is supposed to show it’s working.
I cleaned all the glass and ran a calibration this morning. Then, I followed the instructions to print the ‘precision calibration target’, and observe that the laser managed to score underneath the artwork on the screen. It did.
That doesn’t actually matter, though. The post-process image in the Glowforge UI is not the product. What matters is being able to place a process step accurately on the workpiece, and there things fall apart. I took the test sheet of cardboard, rotated it 180deg and then attempted to put a second copy of the target over the first one. Here’s the result.
I know this is the worst case (opposite corners of the crumb tray), but this is pretty bad. What am I missing here?
