This repository contains the source code for a handheld device designed to interface with GRBL ESP32 via a serial port. The handheld allows you to control your CNC machine, similar to the functionality provided by the GRBL web server and desktop software like GRBL Plotter.
- Machine Control: Use the handheld to control your CNC machine, sending commands directly to GRBL via the serial port.
- File Execution from SD Card: Load and execute G-code files directly from an SD card.
- Spindle Control: Control the spindle speed and other parameters directly from the handheld.
- User Interface: Intuitive interface for easy navigation and machine control.
This code is compatible with all versions of GRBL, providing a versatile solution for CNC machine control. The device has been tested with multiple GRBL versions, ensuring broad compatibility.
