Fun times, lemme tell you. I got a Thermal Runaway Error E1 when printing with a PLA, ranged 215-235. Because of some gaps in the first layer on my first go-around at 220C, I set Cura to 230C and tried again. After a few layers, I got the Thermal Runaway E1 message, reset the printer and tried again. Same error, much later in the print. 225C resulted in the same error.
The highest nozzle temp I can complete a print with is 222C. Normally I'm closer to 200C, but I should be able to go all the way up to 240C?
