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?
The actual number is mostly meaningless. If you have adhesion problems just bump the set temp up by a few degrees. Also the temp will vary across the plate but also vary over time. As the heat soaks into the plate it will be more consistent across it so if there are hot spots now, it’s not a huge deal.
