Get rid of octoprint, this doesn't seem easier nor convenient

Octoprint is a massive help for me running and monitoring 7 printers remotely. It's not an issue, more of a conundrum.

I just disconnect on the printer panel, swap filament, then connect from Octoprint's UI.  Works no problem.

Well done, but you've missed the point! I have somehow managed to have Octoprint connected and still operate the printer interactively on multiple occasions but don't know how it gets into that state.

I have found though, that by some interactions, the printer shows it's normal display allowing for filament loading etc, but remains connected to octoprint. I just haven't figured out what those interactions are since it happens accidentally, although it has been fairly frequent on both my Minis.

Ok, i've checked and it was off, thanks! Also updated the firmware to 4.1.0-RC1 now. Should it work now?

The filament sensor being off means the Mini ignores it, so yes just enabling that should fix your filament sensor problem. 4.1.0-RC1 adds an option to disconnect from Octoprint which lets you change filaments (or do anything you like normally) and then you have to reconnect with Octoprint manually when you are done.

Can you check that the filament sensor option is enabled in the Mini options menu?

Now, when i was run out of filament, the filament sensor just didn't noticed it. The extruder pulled more and more filament as if nothing changed, but the filament was clearly already running through the filament sensor. So now i have the question, is someone facing the same problem? I did not have the time to test the filament sensor by using the normal USB stick and print from there and test if it works without Octoprint.

I face a similar problem with the Prusa MINI connected to Octoprint + filament sensor. Yesterday i tested, if the filament sensor works, when i print over Octoprint and run out of filament. Because i installed the filament sensor just a few days ago.
