MKS DLC32 V2.1 CNC Controller

Description

MKS DLC32 V2.1 CNC & Laser Controller (32-bit ESP32 Offline Board)

The MKS DLC32 V2.1 is a powerful and versatile offline CNC and laser engraving controller board built around a high-speed 32-bit ESP32-WROOM-32U microcontroller. Designed for desktop CNC machines, laser engravers, and similar motion systems, it supports offline operation, Wi-Fi connectivity, mobile/web control, and touch screen interaction for a complete standalone control solution.

This controller directly drives a compatible 3.5″ touch TFT display (such as the MKS TS35-R), allowing you to load and run G-code files from an SD card without needing a PC. You can also control the machine via Wi-Fi using a mobile app or a web interface, and it works with popular GRBL-based software like LaserGRBL and LightBurn for PC connectivity.

The board supports a wide range of stepper motor drivers (e.g., A4988, DRV8825, TMC2208/2209/2225) and is compatible with lasers, CNC routers, and other machines with X, Y1, Y2, and Z axes. Its flexible design makes it suitable for hobbyists and advanced makers who want improved control, speed, and connectivity over traditional CNC controllers.

Key Features:

• 32-bit ESP32-WROOM-32U microcontroller with 240 MHz CPU, 8 MB flash, and 520 KB RAM

• Offline and touchscreen control with compatible TFT displays
