This App supplies the interface between a tablet (10” preferred) and a GRBL CNC machine. The connection is using Bluetooth. The most well-liked receiver is a Bluetooth device known as HC-06. More particulars about the connection is shown on the Help-Tab „Hardware Prerequisites” inside the App.

You can use uncooked G-Code instructions as well as predefined buttons to control your CNC gadget. But the principle function is sending G-Code information to the GRBL controller.
