Thermistor wonky when N / L are switched
I've been tinkering with my Ender 3 and rewired my tool head. Was just testing the thermistor and noticed very similar behavior. Reading about 50Hz and grounding I was thinking if this could be because I thought I was clever and used shielded twisted pair as the wire runs for some length and is tucked together with VCC etc. The shield wire I connected to earth ground to properly shield it, but this was exactly what caused the weird wobbly temperature line. I disconnected my earth ground and a nice flat line. I hope this helps someone else on here too.
