So I was about to print some PETg, and set my temp a little hotter. The hot end maxed out at 226 C. I was able to print ABS at 230 a few months ago, yes it was summer and the room was warmer, but not significantly. I also had issues upgrading to the latest Marlin as the hot end wouldn't reheat to the target temperature after turning the fan on. I thought it was a software issue, but now I'm thinking hardware. So what should I be checking? The HE is getting hot, just not hot enough and there doesn't seem to be any issues reporting temps so I'm thinking not the thermistor? R1+ E3Dv6 Stock firmware and Marlin 1.1.9 (tried both) Anything else?
