Here's something that crops up quite often when I'm using manual nesting to move parts around. In the attached example, I've moved a few of the smaller parts to give them some additional part clearance to ensure that they don't move during cutting. For some reason, offal shapes get calculated differently when I tweak a nest. That should be one offal piece, but for some reason it wants to split it into two.
Just thought I'd throw that out there, and maybe someone would be willing to look into it in their spare time. (If spare time is a thing at Thermwood, someone's probably saying "spare time, are you kidding?!?!")
