We seem to be having a problem very recently with our dove tail drawer boxes. It seems the final outline cut ignores the wasteboard thickness and leaves an onion skin approximately the thickness of the waistboard. Around the dovetails however it is cut cleanly to the table. In watching the final outline cut the depth was 0.627 (Z dimension) which on a 5/8\" thick drawer will leave you too high. If our wasteboard is 0.23, I would think the depth of this cut should be 0.857. We recently upgraded to rolling nest 5.22
Here are some more clues. On those parts designated as left sides, the groove for the bottom is cut correctly. For those parts designated as a right side, the groove for the bottom is too shallow.
