0.7.0.rc1
Pre-release
Release notes
The PrusaLink website has been refactored and contains a number of changes and improvements - see the full changelog.
The READY state, which allows automatic printing from the Connect print queue, can now be set from the printer menu. It is necessary to create a “PrusaLink menu” folder on the SD card - in this folder, a G-Code file is then automatically created. By running it, the printer is set to the READY state.
PrusaLink uses a new API (https://github.com/prusa3d/Prusa-Link-Web/blob/125a944432817d0d7f4b213cca656370f32374c6/spec/openapi.yaml) which adds new endpoints for retrieving printer and storage information and implements a newly preferred method of uploading files using the PUT method that offers, among other things, faster upload speeds.
The LCD screen now displays information about an available Wizard, error notifications, as well as progress and direction of file uploads (Sync|->: indicates transfers from the printer and Sync->|: transfer to the printer)
In the configuration wizard, you can upload prusa_printer_settings.ini file containing a saved PrusaLink configuration. During the configuration process, it is possible to skip the registration and continue to Connect directly. Then, you can finish the registration in the Settings screen on the PrusaLink website. You can also delete the registration from here.
When the setup wizard is run, PrusaLink detects the available ports and displays information about their status and whether a connected printer has been detected on any of them. On successful detection, it switches to the welcome page.
Also, experimental support for MK2.5/S printers has been added. Unlike the MK3 series printers, the MK2.5/S does not have an EINSY port and PrusaLink can only be connected via USB.
The API key is disabled by default and the preferred authentication method is HTTP digest, i.e. using a username and password. The username and password must meet the minimum requirements. The name must be at least three characters long.
The password must meet at least one of the following requirements:
Minimum length 8 characters, 1 lower case letter, 1 upper case letter, and 1 number.
Minimum length 8 characters, 1 special character (e.g. @)
Minimum length 15 characters
PrusaLink now uses adaptive telemetry and only sends important changes, saving bandwidth and putting less strain on the connection to Connect.
PrusaLink supports DNS discovery service, making it discoverable on the network. This allows PrusaSlicer to locate available PrusaLink enabled printers.
The configuration file prusa_printer_settings.ini can now (like the wpa_supplicant.conf file) be inserted into the BOOT partition of the microSD card and PrusaLink will detect it correctly there.
