So, this is going to take some explanation and imagination.

Screenshot from 2024-09-26 17-09-08.png

In the upper left are two ER11 collets, perpendicular to each other, directly attached to Nema17 stepper motors for rotation and ratio.. These are each opposed by additional stepper motors for positioning. The upper pair slide horizontally and the pair to the left slide vertically.

Now all I have to do is get the rotating pair to turn at a specific ratio and, the remaining pair to position.

Seeing as I'm old, a dinosaur, mostly deaf, partially senile and suffering from ED (educational dysfunction) I now have to re-edumacate myself in the fine art of assembly programming or learn IDE for Arduino from square one.

And so it goes....
