Hi! Had no problem wiring up a nema 17 with Arduino uno to control speed and direction of the motor.
*Apologies if this question has been answered!
Now I'm hoping to make it programmable. Idea is to have two pairs of buttons (4 buttons total). Button a1 inputs the current position of the stepper motor into the Arduino's memory, button a2 returns the stepper to that position. Button b1 would input a second position, b2 would turn the motor to that position.
Goal is to make a follow focus for my camera with the ability to rack focus based on programmable positions. As a bonus it would be great to be able to have different settings for speed and easing. As an additional bonus any tips about gearing down the motor for smoother motion would be appreciated!
