Four Button Z-Bed Control for K40 Laser
thingiverse
This button interface was designed to operate the Power Z Table/Bed kit sold by LightObject. I used components from OSEPP because they integrate well without soldering, and a small breadboard holds a DRV8825, so the build should be attainable by most. Here is my B.O.M. https://www.lightobject.com/Power-Z-Table-Bed-Kit-for-K40-Small-Laser-Machine-P722.aspx https://osepp.com/electronic-modules/microcontroller-boards/199-uno-05-uno-max https://osepp.com/electronic-modules/sensor-modules/76-push-button-module https://www.robotdigg.com/product/208/DRV8825-Stepper-Driver You also need a 12 VDC power supply. Almost any will do. The Arduino code is attributed to Martin Raynsford who has generously shared his work under CC BY-NC.
