Installation instructions for the Wi-Fi module for Ender 3, Ender 3 PRO, Ender 3 3D printers
Before you start... ATTENTION! In order to make the modifications presented in the manual it is necessary to have a SKR mini E3 motherboard. You must strictly follow the instructions in the manual. We have made every effort to ensure that the installation and start-up of the device goes smoothly. However, we do not take any responsibility for possible damage caused by improper modification. The device presented in the description is an extension of ESP 3D project. The project is available on GitHub pages.
Installation WARNING! Install with the printer switched off. 1. The wires are arranged in plug in sequence: 1. Red - 5-12 VDC Blue – GND White – TX -> RX Black – RX ->TX NOTE: Other color versions may appear, in which case wire colors should be read: Yellow - 5-12 VDC Orange – GND Red – TX -> RX Brown – RX ->TX Purple - 5-12 VDC Grey – GND White – TX -> RX Black – RX ->TX 2. Plug the connector into the TFT socket on the motherboard. 2. 3. 3.
Network configuration 1. Open the Internet access menu 2. Select the 3D Printer network 3.
