Mini+ Temperature possibly wrong?

I'm not a newb, been using a Mk3S for years.

My mini+ HAS to run at 230C and 90% speed or the PLA "freezes" in the hot end. 

I've already done several cold pulls, replaced the hotted PTFE, replaced the nozzle, repeatedly cleaned the hot end, and added a bondtech extruder.  Still HAS to run at 230C and 90% speed.

Any ideas why this would be the case? Could the unit registering the temperature of the hotted be incorrectly calibrated?

I have a NIST calibrated thermometer; I will check mine and see and report back.

There are some PLA (PLA+) which I use which actually have higher temperature requirements, but I suspect you have excluded that.

In the meantime, can you check for an independent sign that the temperature is wrong? If you print PLA at "too high" of a temperature, then it should result in more stringing. Perhaps if you could run some stringing tests at 230,235,240 and see. If even at those high-for-PLA temperatures, you have no stringing at all, then that could lend credence to the idea that temperature isn't calibrated correctly.

Which heatbreak?
