TMC driver overtemp on brand new Prusa MK3S
Just got a new pre assembled Prusa MK3S today. First thing I did was printing out the "benchy" boat. Everything went fine until it completed (print is fine) then i got "TMC driver overtemp" on the display. Pressing the knob does nothing. Is it normal to get t his error? What courses it? This has not happened on our other older Prusas.

After restarting the printer and trying again I get the same error and and prints stops after a few minutes...

I believe the TMC is a Trinamic Motor Control thumbnail-sized board that plugs into the main Einsy board (if I'm wrong, please someone correct me). You might want to open the door of the Einsy box and make sure everything is seated properly. Something might have jarred loose during shipping. That Einsy box can get pretty warm.

Unfortunately I also suffer this problem, but only when I print in stealth mode, in loud mode I don't get the error (yet).

Are you on firmware 3.7.1? The previous 3.7.0 had print bed heater FET issue that would reports as a TMC Overtemp. 3.7.1 changed the heat bed control frequency to reduce FET heating. One of TMC2130 is near the heat bed FET and would get heated up as the FET overheated.
3.7.1 addressed that issue. I would check that. Another way to is to actually overload the steppers with too much belt tension, but that is less likely.
