Design and Construction
The MKS DLC32 V2.1 is designed as an integrated controller for GRBL-based laser engraving and motion-control systems. The ESP32 provides the processing platform and wireless connectivity, while the touchscreen provides a direct user interface for operating the machine.
Its compact design makes it suitable for desktop laser engravers and maker machines where space and cable management are important. The controller combines wireless communication and local touchscreen control to provide a convenient alternative to systems that require a continuously connected PC.
The 3.5-inch TFT touch display provides visual feedback and allows users to navigate menus and interact with supported machine-control functions directly from the controller.
Working Principle
The MKS DLC32 V2.1 functions as the main control interface between the user’s software or offline job and the connected GRBL-based laser or motion system.
The ESP32 controller processes GRBL commands and controls the machine’s motion and laser-related functions according to the configured system. Through its WiFi connectivity, compatible jobs and control commands can be transferred over a local network.
The touchscreen provides a local interface for monitoring and controlling supported functions. This allows users to perform certain operations directly from the controller without requiring a PC to remain connected throughout the entire job.
For laser engraving, the controller uses PWM control to regulate laser output. Higher-frequency PWM can provide finer laser power modulation for applications such as grayscale engraving when supported by the laser hardware and software configuration.
Touchscreen Control
The integrated 3.5-inch TFT colour touchscreen provides a convenient local control interface.
It can be used for supported functions such as:
- Machine status monitoring
- Menu navigation
- Job management
- Machine adjustments
- Offline operation
- Control and configuration functions
The exact functions available through the touchscreen depend on the installed firmware and machine configuration.
WiFi Connectivity
The built-in ESP32 WiFi capability enables wireless communication with compatible control software and devices over a local network.
Wireless connectivity can help:
- Reduce cable requirements
- Transfer compatible jobs wirelessly
- Monitor machine operation
- Provide network-based control
- Simplify workshop machine setup
WiFi functionality depends on the configured firmware, software, and network environment.
PWM Laser Control
The controller supports high-frequency PWM control for compatible laser modules. PWM allows the controller to rapidly switch the laser output to control its effective power.
This capability can be useful for engraving applications where the laser power needs to vary according to the image or engraving data. When combined with compatible laser hardware and software, high-frequency PWM can contribute to smoother grayscale engraving.
Software Compatibility
The MKS DLC32 V2.1 is designed for use with compatible GRBL-based software ecosystems, including:
- LightBurn
