Since the last update of octoprint, it is not possible to connect the printer with Octopi.
Printer and Octopi starts proper. Also the printer and Octopi will be connected. After half a second the message on the Octopy appears "M600 Hodend too cold to change filament" and on the Printer appears "Printer error, please reset"
What did you already try to solve it?
I thougt it is a problem with the Update and installed Octopi on a new card with the Raspberry Pi manager (Octopi image 0.18.0 with Octoprint 1.8.6) --> no improvement.
I checked connection between printer and Laptop via Simplify 3D --> can connect and move axis.
First I installed the Plugin you recomended and started Octopring again. --> same Error
Than I deinstalled the Telegram Plugin, started Octoprint --> same Error
Than started octoprint in safe mode --> same Error
Than I connected the printer ons again to Simplify. There I saw that this error is as an Echo in the communicaton window.
Now I saw that there is no filament in the filament sensor. so I put in a small pice of filament for a test.
The error disappeard and octoprint worls poperly!
To be honest, I do not understand way this Error appears in the Firmware, but o.k. now it works.
