Thanks johnwasser, ill give the if sequence a go. Its funny, In the attempts I made I actually used both of those exact li!es of code!
Ill try again exactly as you suggest... I must be missing something because those two alterations make perfect sense! I should have cleaned it up and left the assignment of those variables as opposed to the direct write to 90. Looks sloppy!
Do you see why perhaps the constrain may fail? When I tried that I was very confident that there would be no more attempted movement outside the normal range of the servos.. And the fact that you reccomended it makes me believe that my code must be at fault in one way or another, or at the very least conflicting and causing the constrain to not behave as intended.
Ill try now and see what happens!
