A-axis filament winder code help

[v8manic]

Hi All

I'm new to the world of CAM and trying very hard to learn what I need for the the Filament Winder I'm trying build for carbon tube manufacturing for my own use.
What I'm having issues is working out to reset the co-ordinates for the Rotation A-axis as zero without rewinding but reset the x-axis physically back to the zero stop.
At present my code is making the a-axis rewind every rotation it has done back to zero while the x-axis slowly moves back to zero at the same time.

This is my very basic code that I have written so far. My Co-ordinates and so forth I have created an excel spreedsheet to calculate rotaions required to fully cover tube size for a set angle.

If anyone can help with my A-axis issue it would be greatly appreciated.
I'd prefer to learn not just be given the answer if that makes sense, but i'm out of spots to looks for what I'm trying to do.

Thank You
