How to upgrade to the latest (7.0 rc3) without loosing the PrusaConnect printer
Hi, v7 rc3 is out ( https://github.com/prusa3d/Prusa-Link/releases), this appears to be the first version were upgrades can happen INSIDE the GUI, how to upgrade an older version to this version and remain connected to the printer in PrusaConnect in the cloud?
I am guessing a re-image will wipe out all unique keys.
Many Thanks

Hi, yup, even if you were to upgrade Link and the SDK, you'd still end up without camera support as the next version of debian introduces Libcamera support which is what I used. So please re-flash. You can enable ssh on your Pis and recover the prusa_printer_settings.ini files over sftp in filezilla, or you can access the EXT4 partition on the SD card with tools even in windows and get the file off that way. You can then upload it back into the wizard. There should be a button to backup the file in the future tho. Sorry about the inconvnience

Cool, so if i copy the fileprusa_printer_settings.ini off the current version (likley via reading the SD locally) then re-image and connect to WiFi, i can then "restore" this file back with the restore feature in the new image GUI?
Where on the disk is the file prusa_printer_settings.ini located?
Will this new version be the last to require re-image as it has an update feature in the GUI?
How is PrusaLink installed on the MINI and XL (and new MK4)? is it via firmware? if so how much user storage does it have?
Many Thanks
RE:
Any update to the underlying system will still require a re-image. Kinda potentially bad to be running a few years old version of that. But also impossible to implement an updater without locking Link to a single linux distro or only raspi
The file is located at /home/username/prusa_printer_settings.ini
username means your username default is jo and has been pi in the past
Link and Connect integration on the (x)buddy printers is all in the MCU. they put a webserver in there. Madlads. Anyway, it communicates with the flash drive, so that's their storage. But the upload speeds aren't great at the moment. Especially over wifi

When using these printers (Mini, Mk4, XL), i assume without a USB drive you cant upload prints then (as no storage?)
I also assume new PrusaLink version are in the firmware?
Many Thanks

Yup, looks correct to me.
