Features:
The 32-bit high-speed ARM chip is used as the main control chip STM32F407, the main frequency is up to 168MHz, and it has own FPU floating-point arithmetic unit, data processing power is faster and faster.
The circuit board adopts high quality two-layer board and MOSFET tube, the heat dissipation effect is better.
Can accept 24V input, the same system power can reduce the hotbed current to 1/4, effectively solve the hotbed MOS tube heating problem.
Industrial grade chipset makes printing more accurate and fast. It has safety features like overcurrent protection, overload protection, over temperature protection, pre-over-temp alarm.(Turn off the heating switch automatically)
Support offline upgrade function. Copy the upgrade file into the memory card (not included), then insert it into the 3D printer to complete the program upgrade.
TMC2208 motor driver chip is built in the mainboard, replaced A4988. Ultra quiet, low resonance, 256 micro step subdivision, to achieve the step motor in operation without noise, jitter, step loss.
An ultra quiet mainboard and premium accessory for Anet 2020new ET4/ET4 Pro 3D printer.
