if your UM3 is connected to a network, you can monitor the temperatures via a webpage hosted by the printer. Type in the IP-address in your browser and click "temperature graph".
In a dual material print, you will see that temperature setpoints are constantly adjusted. The nozzle that is not being used is lowered in temperature to prevent burning the polymers. And the beginning and end of each layer are printed a little cooler to minimize oozing.

Hi,
When you say monitoring its by looking at the printhead temp reported.by the printer?
And if i understand well this fluctuating temp occurs when the bb core is up and not printing?
How stable is the temp on the bbcore when its printing? I have never checked on mine but it always worked nicely.
Fluctuating temperatures would mean, either a too weak heat cartridge or a malfunctioning heat sensor, but then it should show the same behaviour when the core is printing
