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.iniand
does not get created automatically. The configuration documentation can be
found underprusa/link/data/prusalink.ini. The executable argument
documentation is provided in the standard help text screen shown after
runningprusalink --helpThe
prusa_printer_settings.inifile is created by the PrusaLink wizard,
and can be downloaded from the PrusaConnect settings page once you
register your printer.
