CNC Rotary Macropad

You can build a dedicated macropad for controlling your 3D printing slicing software with snap-part NeoKey switches, a CNC rotary encoder and the Feather RP2040 running CircuitPython.

Each key is assigned to a shortcut for the popular Ultimaker CURA slicing software. The large (and heavy) rotary encoder can rotate around your model and even zoom in/out!

The CNC rotary encoder can switch between three different modes. The lower three key switches can toggle between each mode. This makes the rotary encoder much more versatile allowing you to quickly switch between keyboard arrow keys and the mouse scroll wheel.

The CircuitPython code allows for easily customization. Change the keyboard shortcuts to control any number of software such as CAD, graphics and video editing applications.
