Prusa Connect and PrusaLink are two remote printing solutions developed in-house by Prusa. Its origin is in the management system used in our record-sized print farm located in Prague HQ.

Prusa Connect is a cloud service, available from anywhere.
PrusaLink runs locally on your printer and is accessible only within your local network.

What is Prusa Connect?

Prusa Connect allows control of entire print farms, while tracking each printer separately and providing valuable production statistics.

It's free for Prusa printer owners, including 1 GB cloud storage for G-codes and telemetry. For larger-scale or business inquiries, please contact us.

It is accessible at Connect.Prusa3D.com, in PrusaSlicer, or using the Prusa Mobile app.

What is PrusaLink?

PrusaLink allows monitoring, file uploads, and print control without internet access.
The PrusaLink web interface is accessible only on your local network. Enter your printer's IP address into your browser to access it.

New-gen Original Prusa printers

Printers such as the CORE One, MK4/S, SL1S, and others have PrusaLink built-in. You can connect them using Wi-Fi or a wired LAN (Ethernet) network. Note: On the MINI/+, you must first install the Wi-Fi module to enable wireless functionality.

Original Prusa i3 MK3/S/+ or MK2.5/S

In this case, the PrusaLink name also refers to the required hardware solution of a Raspberry Pi (RPi). PrusaLink supersedes the discontinued PrusaPrint solution (Octoprint and the RPi Zero W).

To use the Prusa Connect, first set up the PrusaLink on your printer.

On MK3/S/+, attach the RPi Zero using GPIO or use the USB connection.
On MK2.5/S, use the USB connection to the RPi.

As a storage, you need to get a MicroSD card, SDHC standard, Class 10, 8GB or more. Preferably, a name-brand card known to work with RPi. Do backups regularly to prevent data loss.

Supported boards (GPIO): Pi Zero 2 W, Pi Zero W
Supported boards (USB): Pi 3, Pi 3+, Pi 4, Pi 5
Unsupported: Pi Zero, Pi 2 and older.

While powered up, do not: Move the printer's axes by hand. Don't connect or disconnect the RPi. Don't insert or remove the microSD card inside the RPi. Don't touch the RPi board.
