Step 1 Introduction

Introduction
Introduction
⬢This guide will take you through the PrusaLink setup on your Original Prusa MK4 printer.
⬢You will need to connect the printer to the network using Wi-Fi or Ethernet connection.
First, read the article about PrusaLink and Prusa Connect to get general information about these services.
⬢Insert the bundled USB flash drive into the printer and keep it there.

Step 2 Networking options

⬢Your assembled Original Prusa MK4 comes with a pre-installed ESP Wi-Fi module.
⬢The preferred network connection type can be selected in the menu Settings > Network > Default
⬢Make sure Wi-Fi is selected.
⬢If you prefer the wired Ethernet connection to the network, use the connector on the back of the printer and skip to step 7.

Step 3 Setting up Wi-Fi

⬢Hit Continue. The software in the printer's Wi-Fi ESP module will get updated automatically.

Step 4 Generating the credentials

Generating the credentials
⬢Hit Yes when prompted to generate credentials.
The printer will generate a prusa_printer_settings.ini configuration file on the USB drive.
⬢Remove the USB drive from the printer.
If there is a valid configuration file on the USB drive already, you can skip these steps and just load it straight away.

Step 5 Editing the configuration file

⬢Connect the USB drive to your computer.
⬢Locate the prusa_printer_settings.ini file on the USB drive created by the printer. Open the file in any text editor.
⬢Go to the second line named ssid= and write down the name of the Wi-Fi network you want to connect your printer to.
Note: The bundled ESP Wi-Fi module supports 802.11 b/g/n 2.4 GHz networking. A 5Ghz network will not work.
⬢Now, go to the third line named psk= and write down the Wi-Fi password. Make sure nobody is watching!
⬢Save the file on the USB drive.

Step 6 Loading the configuration file

⬢After the connection was established, navigate to the menu Settings > Network > IPv4 Address. Note down the IP address shown.
⬢Open up a web browser on your computer. Insert the IP address into the address line and open it up as a webpage.
Note, this IP address is accessible on your local network only and might change over time according to your network setup.
We recommend using Chrome or Firefox browser as there are login issues when using Safari or Edge.

⬢To start printing wirelessly, navigate to the Storage tab in PrusaLink.
⬢Select a G-code file to be printed or drag&drop it into the marked area.
⬢Make sure the printer is ready to print:
⬢There must be a USB drive in the printer.
⬢An empty and clean steel sheet must be attached on the heatbed.
⬢The printer should be on the home screen. If there is any prompt on the LCD screen, the printer will reject any remote command.
⬢After the file is uploaded, open up the file details. From here, you can Start Print.

Step 10 Prusa Connect
