What you need

Board: Cheap Yellow Display
Parts: Rotary encoder (MPG handwheel)

FluidDial is a handheld pendant for CNC machines running FluidNC. On the Cheap Yellow Display it shows machine state and position, jogs the axes, homes and probes, and starts files from the controller's SD card. It talks to FluidNC over a UART cable or over Wi-Fi. Original project by bdring on GitHub, GPL-3.0. Chipnik hosts the release binaries unchanged so you can flash them from the browser.

The CYD Dial Pendant page in the FluidNC wiki shows how to add a rotary encoder for smooth jogging and how to wire the UART cable. Without the encoder you still get the touch screen controls.

Firmware files come from the 1.5.1 release.
