Some of these?

@DaveX

• Example 2 -- bounce a stepper back and forth between extremes with acceleration and a Finite State Machine
• Example 3 -- Stepper jog buttons and speed control
• Stepper Button Example -- Move stepper to five different absolute positions based 5 different buttons.
• Stepper Reference Example: Set a reference position with a limit switch and move to specific positions with button presses.
• Stepper Reference_2 Example: Three axis steppers with X,Y homing cycle
