Anet ET4 3D Printer Motherboard Control Board 32bit Auto Leveling Filament Missing Remind Resume Printing 3D Printer Part

Using 32-bit high-speed ARM chip as the main control chip STM32F407, the main frequency is up to 168MHz, compared with mega 2560 (16MHZ), the data processing capacity is faster.
The use of high-quality MOSFET tube has better heat dissipation effect.
The special power supply is used. The chip supports 12-24V power input.
The power of the same system can reduce the current of the hot bed to 1/4, which effectively solves the problem of MOS tube heating.
● Industrial-grade chipset, printing is more accurate and faster, with over-current protection, overload protection, over-temperature protection, over-temperature alarm and other safety functions. (Automatically turns off the heating switch)
Support offline upgrade function, copy the upgrade file to the memory card, insert 3D printer to complete the program upgrade.
The TMC2208 motor driver chip is built into the motherboard, replacing the A4988. Ultra-quiet, low resonance, 256 micro-step subdivision, realize stepper motor without noise, low jitter, and no step loss during operation.
