Creality E3 Free-runs TMC2209 Silent Mainboard 32-bit

Unlock the infinite fun of 3D printing

Sporting a reduced size, this motherboard offers all the essential connections and utilities needed for proper operation including a TF card slot, micro-USB port, and connectors for auto-leveling and filament sensors.

Integrated heat spreaders prevent the motherboard from overheating while anti-static control discharge prevents unwanted electrical interference. The E3 is constructed from a 4-layer gold process which enhances signal bandwidth, reinforcing electrical throughput.

To ensure proper operation, the ARM Cortex M4 chip maintains drive current, managing output and noise reduction for greater performance.

Compatible with Marlin and Klipper

Drive and control integration. The mainboard can run the preinstalled Marlin firmware alone or freely run Klipper firmware with a Raspberry Pi

Extended Function Interface

Support for Auto levelling, filament run-out detection, power resume. Easy to install and DIY

Pay attention

Please ensure that the positive and negative poles of the power supply are correctly connected before powering on.
Please do not plug or unplug the motor when the power is on, so as not to damage the drive.
The motherboard is pre-flashed with the basic version of marlin firmware (Ender-3), which can be used directly, or you can download the open source code to compile the firmware as needed.

Firmware Update Instructions

First format the TF card, and create a new "STM32F4_UPDATE" folder in the root directory, and download the firmware bin file to the folder
Insert the TF card into the TF card slot of the motherboard, and power on it, wait for the system to start up (the display screen is displayed normally)
