Feature: 1. Excellent Sensitivity: The 3D printer control board uses a 32 bit high speed ARM chip and the self developed main board. 2. Remote Printing: The 3D printer mainboard controller can be easily upgraded with firmware via storage card, with high speed WiFi module, access to the cloud to achieve remote printing. It supports setting the stepper drive current in the config file, so you no longer have to worry about adjusting the current to burn the mainboard. 3. Multifunction: You can design your own boot logo and all buttons, at least 15 command buttons can be customised, you can design your own boot logo and all buttons. Support for breakpoints, power saving, power failure detection, automatic shutdown, etc. 4. Efficient Heat Dissipation: This 3D printer control board uses MOSFET for better heat dissipation, 12 to 24V power input, reducing the heating bed current by 1/4, effectively solving the Mosfet heating problem. 5. Main Usage: The 3D printer mainboard controller is plug and play on for Ender series printers with the BTT SKR MINI E3 V3.0 control board.
