All I need is that math formula and I need to try it to see if I will end up with better results.

You mentioned it works just like TPI, for the most part the designer software tells me how fast both the carriage and the mandrel need to move in order to get the desired winding angle. It is just determining the amount of turns and the C advance to end up with proper filament placement is what I don’t know how to obtain.

Let me think about that for a bit.

Known variables:
Winding angle
Filament width
Carriage Speed
Mandrel Speed
Length of wind

Unknowns:
Lead
Total turns
C advance

The 3 unknowns can be calculated from the known variables, I just need to figure out the formulas that you can plug into Excel. I'll work on this a bit this evening.
