Summary

  • Added support for Power Panic
  • Set Ready and Reprint
  • Enhanced MMU support
  • Raspberry Pi 5 support
  • Other improvements and fixes

This is a stable release of the PrusaLink 0.8.1. Please note that firmware 3.14.0 or newer is required. You can update your existing PrusaLink using an OTA update. In case of issues, consider flashing the full system image.

Added support for Power Panic

PrusaLink now supports manual Power Panic recovery. The printer will keep the bed heater ON and wait for user confirmation before resuming the print.

Note: If you're printing from the printer's SD card with PrusaLink connected over USB and encounter issues with Power Panic recovery failing, you can try a new option named reset_disabling, details of which are in the prusa/link/data/prusalink.ini file of this GitHub repo. This workaround is a last resort and is not recommended for regular use, as it may cause EEPROM fatigue.

Set Ready and Reprint

The printer now recognizes when a host is connected, enabling it to display new menu items on the LCD screen. "Set Ready" informs Connect that the printer is ready for another print job, while "Reprint" runs the last print job again.

Enhanced MMU support

PrusaLink now sends information about the MMU to Connect. Currently, only the connection status is visible.

Raspberry Pi 5 Support

This release of PrusaLink 0.8.1 will run on the newest Raspberry Pi 5. The Raspberry Pi 5 can be connected to the printer using USB connection. However, if you plan to connect it to the Einsy Raspi port via GPIO pins, a manual configuration is required.
The port to use should be named /dev/ttyAMA10 while the autodetection tries to use /dev/ttyAMA0

Here's a section from the README describing manual configuration:

PrusaLink behavior can be altered using command arguments and configuration
files. The default configuration path is /etc/prusalink/prusalink.ini and
does not get created automatically. The configuration documentation can be
found under prusa/link/data/prusalink.ini. The executable argument
documentation is provided in the standard help text screen shown after
running prusalink --help

The prusa_printer_settings.ini file is created by the PrusaLink wizard,
and can be downloaded from the PrusaConnect settings page once you
register your printer.

Other improvements and fixes

  • PrusaLink hosted prints now count towards statistics (Print hours and Distance)
  • Fix for Temperature Model calibration failing while PrusaLink is connected
  • The "Tune" menu now does not show up when PrusaLink connects to the printer
  • The PrusaLink 0.8.1 images are based on Raspberry Pi OS release 2024-03-15, running Debian 12 Bookworm
