Carries highly modular open source firmware Marlin 2.0, which facilitates user DIY and secondary development;

PCB board wiring is rigorous and beautiful, and has been specially optimized for heat dissipation.

Special power chip is used to support 12-24V power input.

Acceptable 24V input, the same power can reduce the hot bed current to 1/4, effectively solve the hot bed.MOS tube heating problem;

Upgrading firmware by SD card makes operation simple and convenient.

Firmware is used to set the driving current so as to avoid burning out the driving caused by manual regulation of the current.Convenient, safe and reliable;1)ARM Cortex-M3 Series STM32F103RCT6 Master Controller with 32-bit Main Frequency of 72MHz Chip;
2) Supporting display :2.8 inch, 3.5 inch color touch screen and Ender3 printer LCD12864 screen;
3)Support BLtouch, RGB color lamp, block detection, shutdown and other functions;
4) Integrate UART mode of TMC2209 to simplify debugging of motherboard and driver.Reserve expansion ports for TMC2209 pins to facilitate users to use DIAG instead of Endstop.
