Alignment Error Map - What is acceptable?

One can see the alignment will be out when the outline of the board is not shown square.

Since we started production, we’ve been going through a time consuming process at the factory to record huge amounts of data on the performance of each unit’s camera. Over the past months, we’ve been developing advanced software to use that data for more accurate image placement. We’ve finally been able to roll that out for both new and existing Glowforge units so you can take advantage of it. You don’t need to do anything - it’s been rolling out slowly over the past few weeks.

Did anybody notice an improvement in accuracy in Dec? Examples like this seem just as bad as they ever were. The announcement implies there should be a big improvement if they have started using machine specific calibration data. Perhaps the machines shift in transit or need to be on a perfectly flat surface for the calibration data to be valid.

It would be interesting to see how it varies with a small shim under a corner.
