It's sensing transient events, perhaps a draft, and recovering before they become a problem.

If this persists try recalibrating.

Cheerio,

RE: Thermal anomaly on firmware 3.12.2

A well-known and often discussed problem if you are running 3rd-party parts . Prusa writes on this matter:

"In case you are running 3rd-party parts like the Revo hotend, the thermal model will report errors because it needs to be trained on a large set of samples. We welcome anyone who’s willing to help us with testing. Please provide log files in GitHub issue. For now, you can disable the Thermal Model if you’re running the Revo and you’re certain that your printer is working fine. Connect to your Printer via Pronterface and send G-code M310 S0 followed by M500 - then you can continue using the firmware with third-party parts."

If nothing has been changed on the printer and the error still occurs, I would contact the Prusachat.

Hi Diem,

I just reassembled and then upgraded firmware to 3.12.2 on my Prusa I3 Mk3S but I'm getting a temperature calibration error.  Your discussion is way above my head and this error is just a time-waster as far as I can see.  Is there better information for me so I can stop it?  There is nothing special or new on my printer.

Meantime I'll see if they have time to chat at support.

Is this a kit or a preassembled machine?

If the problem persists when the printer is protected from ramdom breezes then it might be a loose connection between the thermocouples and the Einsy.

Prusa Chat should be able to help.

Hi Karl,  I just updated my 3.12.2 yesterday and I am running a REVO 6.   I am using Octoprint and I tried the M310 S0 then the M500.  No luck still has the same error.  I rolled back to 3.11.0 and back in operation.  I think I will stay at this revision for a while and just monitor my temp with other methods. 🙂  I assume the (0) in S0 is numeric?  That is what I used.

RE:

Thanks for the information! I would urgently forward the problem to Prusa or github. Probably several more people have the same problem.

Prusachat: Just log in with your Prusa account and select the eshop. After a few seconds the chat window should appear on the lower right corner. If the chat window does not open, disable a possibly activated adblocker or try another browser.
