MK3S Thermal Anomaly on Firmware 3.13.2

I just updated my Prusa MK3S (stock, no modification) to 3.13.2 and I'm running into Thermal Anomaly failure message. I went ahead and did the PID calibration that completed and it looked like it was saving the settings. Then I proceed to try and unload filament, but then I'm hit with the Thermal Anomaly error.

Snippets I pulled from Octoprint when viewing the messages

As you can see the PID Autotune finishes, and then it stores the value and that looks to be fine, but then I get an ERROR triggered. Not sure what's up. I was originally on 3.11.0 where it was working fine, but I believe 3.12 introduced the Thermal Safety stuff.

Any ideas on what's up or what more to gather to troubleshoot this?

I was reading on the Thermal Calibration documentation and see possible codes for temp model debugging, but I don't think I need to do that since the PID Calibration finished without error. Is my MK3S too old that I just need to disable Thermal model protection? Or do I just need to downgrade firmware? Please note I bought my MK3S back in 2019, so maybe my MK3S is missing something the newer ones had?

RE: MK3S Thermal Anomaly on Firmware 3.13.2

Did you redo the Thermal Calibration after the PID?

Yes, I tried the Thermal Calibration, that fails during the calibration process. This is from after a cold boot up.

It heats the nozzle up to 230c then tries to cool down below 50c, but then encounters an error and aborts. When I tried to recalibrate again, it fails during the heat up to 230c.

RE: MK3S Thermal Anomaly on Firmware 3.13.2

It might be helpful if you do a full factory reset and then recalibrate the printer.

RE: MK3S Thermal Anomaly on Firmware 3.13.2

I would like to avoid full factory reset and leave that as a last resort as I don't want to have to manually redo the first layer calibration again. How can I get more information on the error that the printer's encountering?

Like what are the values being compared here? What is the negative value here from? what is the 1.2 value specifying? In some of the instances I see that the value is indeed non-negative and larger than 1.2, but again I don't know what that value is supposed to be in reference to. If I know where this is from it might help me to investigate further.

Same issue here. I tried all now. I can't print. Always thermal anomaly. 🙁

RE: MK3S Thermal Anomaly on Firmware 3.13.2

We have quite a few Prusa MK3S+ printers here and all were updated to the new firmware with no issues.... except one that had a "Thermal Anomaly." After a lot of digging around, and almost taking the Thermistor apart etc., I first tried backing up to Firmware 3.11 and have had no issues since. Our plan here is as we encounter this issue, reset the factory data and then back up to Firmware 3.11. 

What you describe above is exactly what we encountered but what's funny is no other machines have had a "Thermal Anomaly" issue yet. At a loss as to how some will have this issue and some won't.

RE: MK3S Thermal Anomaly on Firmware 3.13.2

Curious about when the errors started for everyone. I've had my firmware updated for a few weeks now, lots of successful prints, but then I'm just now getting all of the errors. 

Anyone else printing good for a while and then having this issue? or was it apparent right when you updated?

RE:

I have a different problem,  the Thermal Calibration finishes successfuly but when i preheat or print Thermal Anomaly appears on the screen and it makes some loud beeps but it continues to heat up and i can print, it works ok but it's kind of annoying

RE: MK3S Thermal Anomaly on Firmware 3.13.2

I upgrade firmware when it came out and didn't have any thermal anomaly warnings until this week.  Hadn't printed with PLA for months and was doing some PLA prints and kept getting errors during the first few layers of the print.  I print in an enclosure but had the doors open for the PLA.  No real drafts to affect the print.  May do a thermal calibration again.

I even had a thermal anomaly while doing a PET pre-heat today.  At least it doesn't stop the print.  Going to retry the calibration.

RE: MK3S Thermal Anomaly on Firmware 3.13.2

now it's random, or might be because of the ambient temperature, today before sunset i didn't have any errors, now it started to have TM error again.
