Ultimaker 2+ swapping material doesnt work...

[Attenbach 0]

Hi guys,

so i started printing as usual, the plan was to resume the print after 7 hours with a different material as i used to do:

Pause it, select Change material etc.

Now this time after the 7 hours, i went throught that process again. When the Printer threw the old material out, i selected PLA as i always do (cause i print with PLA). Then though, it said:

Heating printhead for material Insertion.

then after some time, the "heating" changed into a "cooling" and then swapped between the two every second or so. Now i couldnt even resume the print as the material was already ejected. I had to factory reset the Printer, loaded the material and did a test print to see, whether the Problem still remained.

Now it did the same Thing again.

Is this a Software bug? I mean, all temperature sensors must be working fine since it started printing.

Any tips? I mean i could try to install the very latest Software update, since it didnt do the bug before i updated i a month ago or so...

Greets, Ka
