///// Turn the stepper 200 steps with a 1 sec delay between steps at 60rpm
/// then reverse the direction and do 50 steps at 20rpm with a 1sec delay between steps
1 sec delay between steps at 60 RPM doesn't make sense. If you have a 200 step motor and 60 RPM, it will need 200 steps per second, not 1. Likewise, 1 second between steps is about 60/200 RPM, or 0.3RPM.
stepper.setSpeed(1) sets your speed to 1 RPM, not 60. Try setting the value to 100 or so and see if it is actually working.
