FINE WORKMANSHIP: The motherboard adopts an ESP32 WROOM 32U module, embedded with a dual core 32 bit high speed MCU, and a clock of up to 240MHz. And integrated with WIFI and Bluetooth modules, the performance is very powerful. In addition, the module is equipped with an 8 megabyte flash storage chip, providing effective protection for more application scenarios. BASIC PARAMETERS: 32 bit STM32 processor, supporting storage card storage, expandable WIFI module, power outage relay module, material outage detection switch, and external card slot. TMC2209 STEPPER MOTOR DRIVER: Ultra quiet, designed to improve your performance and prevent overheating. The board has a smoothly surface, which makes it easier to grip and control. APP CONTROL: The board can achieve functions such as fast carving, webpage control, and mobile app control. The installation holes and circuit board sizes of MKS DLC32 are compatible with for MKS DLC and can also be used with for GRBLaser and for LightBurn PC software. GOOD ACCURACY WORK: Engraver touch screen can be well coordinated with the machine controller to provide good accuracy printing operations and print premium and stable products. The engraving effect is more delicate than the traditional desktop engraving scheme, and the grayscale expression is smoother.
