I've been chasing a print issue for the past two days on my new Trident build, and finally found the issue. Symptoms are "tearing" on layers, extruder jams and miscellaneous problems. Turns out that when you replace your kit supplied V6 clone with a Revo, you also need to remember to update the thermistor so that it measures the right temperature!
For reference, it's "ATC Semitec 104NT-4-R025H42G" in the Revo, not a Generic 3950
