【Open Source】Engraving Machine Scheme Control GRBL_ESP32 Based on COF Screen

——From the DWIN Developer Forum

The solution adopts T5L chip as the main control, controls GRBL through serial port 2, and drives the motor to control the main engine of the engraving machine to generate the engraving path base path of X, Y, and Z axes, so as to realize the automatic engraving operation. It has the functions of beautiful interface, precise control, multi-axis control and automatic tool setting.

Description:

1. Control GRBL through DWIN serial port 2;

2. The GRBL serial port realizes the message, segmentation and interception display;

3. The screen controls various functions such as GRBL movement by sending instructions;

4. Support handwheel control, compatible with Weihong handwheel interface definition;

5. Screen parameters can be saved after power off;

6. By controlling WS2812 to display status lights such as idle, stop, and work;

Solution Design:

(1) DGUS engineering interface design drawing

Notice:

1. GRBL's ESP32 can use the original version without modification;

2. Open the download attachment of the screen PCB file with Easytron, and its schematic diagram and PCB can be directly proofed;

3. The kernel file should be the latest one. This project uses the kernel version in the attachment, and the kernel needs to be updated separately.
