A nozzle of my printhead got clogged

[xchrisd]

I guess there are many problems about clogging. Dont have a Artisan but toolhead is the same.
One problem seems to be the temperature regulation of the right extruder:

Dual Extrusion - filament stuck in nozzel (not clogged)

My guessing is, the main problem comes from the inconsitent temperature regulation of the right extruder. I played around a bit with pid and there is NO change on the right nozzle in temperature rising and falling ±7 degree. Left extruder regulation is ok, the temp sits on point. @Riskey, please forward to your devs, right nozzle has a very limited temperature regulation, pid values doesnt work for the right extruder. I am printing only with the left nozzle right now and have nearly similar …

Are you observing the same temperatureshifting?
