Edit: One thing I’ve run across, on the “Bevel Angle” sheet, the first entry for “Wheel Diameter...” has a strange drop down menu that shows up...
It looks like a compatibility issue. Do you use MS Excel or other app?
It is dynamic drop down menu which shows wheels from "USB height" sheet in all
visible columns. If you hide a column, corresponding wheel is exluded from drop down menu. Excel doesn't provide a function how to do it directly, therefore auxiliary formulas are used, unfortunately they can be incompatible with other apps.
Here is slightly modified version with static drop down menu, which has limited functionality and always offer all wheels...
I can confirm that your results are identical with my results with an accuracy of 0.001 mm. Congratulations!
Thanks for verifying, I really appreciate it.
