I think you and Zax deserve Sainthood for the diligent work and quick responses.
Have been bit by the "units" this week. In the end it was my problem. My fatal word is "Assume".
A few comments with no priority:
1. We place a lot of trust in software tools. I use linux (25 years)
and expect that the user community will detect and fix errors. Apparently
this is not applicable to graphic arts or laser tools.
2. We tend to link multiple (export/import) files trusting the exported to "do it right"
and the importer to check and provide nice descriptive error messages.
3. Tools change and the auto updates can large and taken for granted.
4. Every large application has bugs. Fixing a bug that a user has a "work around"
can be worse than the original.
5. Once something is assumed working (my downfall) it is often easier to blame the
current or newest change to be the problem when in reality the problem has been
there all along looking for the best moment to cause grief.
6. Murphy was right.
7. Learning 3 new applications, with 3 different got ya's, at the same time is mind boggling.
We typically work solo without anyone to provide real time reality checks. I can propagate
and defend mistakes.
8. CNC machining for the hobbyist is in its infancy. We have not had any type of industry fallout
where the weak and crappy tools get junked. I don't think we can even buy a book.
9. It doesn't help that much of the hardware is marginal sold by non-human entities with no
manuals or tech support. What percentage of our group joined with a statement similar to:
"I bought the XYZ laser etcher from ABC and it doesn't work"
