I've been having issues with filament jamming in the hot ends/nozzle so I took the assemblies apart today to do a thorough cleaning. I did manage to snap the throat tube on the one nozzle, but that's a different story... I assembled the other nozzle back to the printer and went to run a print. That's when I noticed that the hot end will always stop 10°C shy of the set temperature, i.e. I set it at 220°, it gets to 210° and won't go any higher, 240° set, stops at 230°, etc. I moved the hot end to the other extruder with the other thermocouple and heat rod and the same thing happened. The heat bed comes up to temperature just fine. However, I cannot get anything to start printing until this issue is resolved.
Also, I have the N2 with dual extruder and V2 hot ends.
Thanks for any feedback.
