I forget... Do these kinds of motors change their current draw 
significantly when they stall? If they don't, a current probe may not be 
a reliable stop indicator.

Also, regarding the challenge with 450 degree rotation... There's no 
requirement that you actually use all 450 degrees. Just stick to 0-359 
and it will make things a lot easier to start with. Once it's all 
running, you can go for the fancy stuff.

Good luck with the project,
