Octopi lose connection to Printer

Post by Jaraya » Tue Apr 20, 2021 12:21 pm

Hello @ll,
I'm new here and hope to find answers. I searched the Forum but did not find a solution… so here is my question / problem… ;)

On Christmas I got an Acrylic Prusa I3 Pro B and had a lot of fun with trying to get some acceptable output... not so easy but I learned a lot the last weeks. The Printer is connected to an octopi (Raspberry Pi 4) with octoprint in Version 1.3.12. I had the feeling that it worked well but now I have a problem with this constellation https://100001.onl/ https://1921681254.mx/

After starting the print everything works well but after an amount of time (not always the same timespan) the print stops abrupt…
I found out that there is a message in the log that says, “cold extrusion prevention” (the current print runs with PLA/195°C). In addition, the octopi loosed/closed the connection to the printer. Looking into the octoprint logfile I found more “cold extrusion prevented” messages there.

Is it possible that I have a problem with the extruder heating or the temperature sensor? I have no Idea now what to do… would be happy to get some ideas / input from you.
Thanks in advance!
