A Little Follow-up
So, during the last prints that I wrote about in the earlier post, I ran into an issue on the Prusa Mini+. All of a sudden, the Octoprint lost the connection to the printer. It might have happened before but then I just had to refresh or, at most, restart the page to fix it.
This time I restarted the page during the print and then, even after the print was done, I tried to connect. Nothing. Completely dead. Well, not dead. Better is probably death, they did NOT want to listen to each other.
