Thermal calibration does not start

Hi,

I have upgraded my mk3s+ to 3.13.2 and since then I have the warning that the thermal model has not been calibrated.

When I try to do so, the toolhead moves to the center of the bed and sit there forever without doing nothing. I have tried to disable the thermal model via terminal, with no luck, it still complains.

What should I do to get rid of that warning?

Since doing the same mine goes to 110 and then shuts off. Prusa has yet to provide a suggested fix that worked.

I have the very same issue on the mk3s+. Did a firmware upgrade to 3.13.3, and after the update the printer greeted me with a continuous MINTEMP and then it's as you described.

 

Did you find a solution, or do I need to fall back to the old firmware (printer hat 3.10.x)

RE: Thermal calibration does not start

In my case - probably a different issue than yours, after the firmware-update the firmware can not read the extruder temperature anymore. Not really firmware-related, and probably not the reason for your issue, but I want to leave it here anyways:

The original firmware in my case did use a different port on the board for the extruder temperature sensor. According to the previous owner the original port was damaged, and so the one remaining port was used and changed in the firmware. With the firmware-update the port was reset to the original port, with that no temperature data was available, and with that came the issue.

For my case I have not realized a solution, but it will either be a new board, or manipulating the firmware as described here: https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-hardware-firmware-and-software-help/reassigning-nozzle-thermistor-port-to-t1/

I just updated my firmware to the latest version (3.13.3) and got the msg "thermal calibration not completed" so it appears no fix has  been accomplished? I guess I'm going to to a previous version  which was working
