Calibrate bed temp
-
Is it any way to calibrate the temp reading from the printbed in RRF3?
I have a PT100 on sensor on my hotend so i trust that reading more than the thermistor. The bed temp 1,9c lower than the reading from the PT100, so i would want to adjust for that.

thermistors are inherently more inaccurate.
normally the thermistors are just stuck to the underside of the bed with some kapton tape.
just get a pt1000 (or even a pt100) like this https://de.aliexpress.com/item/32872179878.html and use for the bed. -

the one with the lowest tolerance. PT100 Class A.
I have not used a PT100 on the bed, so i dont know how it is in terms of interference.
i use a pt1000 (you can connect them like normal thermistors) -

Hmm ok, meh might as well order one of both for the sake of experimenting
thanks for the link
