1.The performance of the ARM-class Cortex-M3 series LPC1768 main control chip with 32-bit frequency and 100MHz is greatly improved;Reserve the extended port SERVOS of the PWM signal to support BL Touch
2.Support Resume Printing While Power Off,Filament Break,CE Certification to adopt 4-Layer PCB with “Gold deposition technology” which capability is more stable and better heat dissipation
3..Onboard TMC2130 driven SPI mode of operation and TMC2208 driven UART mode,The utility model eliminates the complicated wiring process and can be used only by simply plugging and unplugging the jumper cap;
4.The high-performance MOSFET tube has better heat dissipation effect; it supports functions such as power-off continuous shooting, material cut detection, and shutdown;
5.Use the power selection design ,to separate the USB power supply from the switching power supply, effectively avoiding short circuits,Causes the computer's USB port to be bur
