75 degrees = 68 degrees. No wonder I couldn’t get things to adhere well sometimes.
As a side note, the temp varies wildly along the plate base. An enclosure would definitely help here.
Has anyone else tested the actual temps versus the set/displayed temps and noticed a difference?
Agree. Thing that matters is consistency of measurement, but thermistors tend to not drift very much. One thing for op to keep in mind is that thermistors tend to be mounted to the bottom of the bed and there will be some temperature difference between the bottom on the top - especially if the printer hasn’t had the opportunity to soak. The other thing to keep in mind is how the terminator is attached to the bed. On my i3 it was just a piece of kapton tape, which meant there was often an air gap between the thermistor and the bed. I’m sure this resulted in quite a bit of weirdness.
