While Printing Nozzle Stops, Display shows "M105"

[Freisl]

Hello,
since one month im the owner of the Mc2. All good so far.
Today the first problems.

I use Ultimaker Cura 3.6.0.

What happens....


1.Starting to print
2.after a while the nozzle Stops and u can see in the Display of the Printer the command "M105"
3.So if i do nothing the print is not continueing.
4.So i press the Button near the Display. Printer continues with the print.

This behavior is new, what is it?
Before i had 2 prints, each of them was 20hrs with no Stop....

Is Cura sending for some reason the Command "M105" for getting the extruder Temp? Maybe becaus of a lost Signal while printing(for example temperature Sensor broken)?

Greetings Chris

You can attach the gcode file(The forum support zip type file).
Then we can help to check it.
Or you can use the slic3r to slicing it then test it.
