This is a simple 3 axis stepper motor Arduino Shield for the DRV8825 Step Stick. It works with GRBL on an Aruduino Uno or TinyG on an Arduino Due. The circuit board for this shield is single-sided and can be milled on a precision CNC machine using a 1/32" endmill.
To get started, select 'stepper shield' in the 'projects' list in the app below to access the design and click 'Make' to download the cut file for your milling machine.
