Stepper Motor Speed Controller by dvanommen

Last crawled date: 3 years, 1 month ago
This is a controller I made for motorizing the leadscrew of my Unimat Lathe. It uses a 10k potentiometer for speed control and two momentary push button switches for the motion (one forward, one reverse). The pot is one I pulled out of an Arduino kit - I modeled a recess into the body of the controller so it fits in nice and snug without needing to be glued in. But if you have one that doesn't fit, you can just open up the hole for the shaft size you need and then epoxy the pot onto the back of the controller body.
Two M3x32 screws and M3 nuts hold the Body and Cover together.
The push button switches are from Amazon:https://www.amazon.com/gp/product/B07F9PLSRY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
That's not an affiliate link, I'm just letting you know which one was used. The hole size is 12.5mm, so any push switch that fits will work. Or change the hole size and use what you want!
I'm using an Arduino and an A4988 stepper driver to control a Nema17 motor. I've uploaded the Arduino code for you if you want that as well. You can look through the code to see which pins are used. The nomenclature should be easy to identify.
This can also be used for anything that needs two push switches and a potentiometer for input! Doesn't have to be for a stepper motor. Whatever you use it for, please share!
