ATTENTION: This article is obsolete and no longer maintained. Please update your MINI/MINI+ to the latest available firmware and then use newer web user interface PrusaLink.


Starting the firmware 4.0.5, you can monitor your Original Prusa MINI over your local network via the web interface called Prusa Connect Local. Prusa Connect Local is still in development and is an initial release of Prusa Connect.

It is a platform for full remote control of your printer, much like Octoprint. However, it can currently only provide a live view of your ongoing print's progression, give an estimated completion-time by connecting to an NTP Server (MINI) and your machine's temperatures. Full control of your printer will be added in future releases.

Check out our Blog, page for Firmware, Drivers, and Apps or social media profiles, where we publish information regarding updates.

How to connect

Connect the printer to your network using a LAN cable. The Ethernet connector (RJ45) is situated in the back of the electronics box (green arrow).

The printer has DHCP turned on by default. Go to LCD Menu - Settings - LAN Settings and check whether the IP address has been assigned correctly. Common IP-ranges are 192.168.0.X or 10.0.0.X. Since it is connected by cable directly to your router, you do not need any password as you would with WiFi.

Depending on your network, connecting to it can take up to ~30 seconds after you turn on the printer. An icon will appear in the top-right (Right picture - purple arrow) once it has a connection.
The IP Address within Lan settings may not update automatically. Exit Lan settings and return, or select save or load settings to force the IP fields to update.
Not connectedConnected
If IP "" is shown and there is not a network icon in the top-right, an IP address has not been assigned and you are not connected.

On your PC or smartphone, open a web browser of your choice, enter the 'IPv4 Address' into the address field then hit Enter. It will now load the Prusa Connect Local web interface.

If you can't see the interface, confirm that the IP is correct and also try a different browser.

Save/Load Settings

Save Settings options will create an INI-file on the USB drive containing your IPv4 address, netmask, gateway, and MAC address. It can be edited from your computer using a text editor, should you have the need, for instance, if you are setting up a static IP address for your printer. This file can be loaded to any Original Prusa MINI, using the option Load Settings.

If any item in the INI file contains an incorrect IP address, the item is ignored. All items are optional.

type=DHCP //or "STATIC" (UPPERCASE!), if a static IP is set up in your router's config.
hostname=PrusaMINI // Optional.
address= // From your router's config.
mask= // From your router's config.
gateway= From your router's config.


As routers and networks have different configurations, it is hard to provide support in this respect. Please check the documentation of your network to whether you need to grant access for the printer or similar. However, if the MAC Address, within 'LAN Settings', is displayed as "ff:ff:ff:ff:ff:ff" (red square picture below), it may indicate an issue with the Buddy mainboard. If this is the case, please contact Customer support.
