Thanks to both of you. It appears that this bug has gone away as mysteriously as it appeared.

@dc42
there is definitely a difference between firmware 3.4b2 and 3.4b2+2
below is a screen with temperature reading for 3.4b2 and below for 3.4b2+2 -

Hi all,

I updated my printer after vacation and noticed the same issue.
I have upped the LC1 to 3.4.0beta2+2 and readings are back within expected range.

No recalibration done yet.

(I was not sure if there was a toolboard v1 reported or tested with the issue.)

@dc42 Sorry for not following up further, I am currently on vacation away from my printer, but I am happy to try the builds when I am back in a week if it still makes sense.

@pixelpieper the problem appears to be solved in firmware 3.4beta3.
