X1 bed temperature reading to low in idle mode

Hello,
I recently saw that my bed temp reading is lower than chamber and nozzle temp.

Nozzle: 21 C
Bed: 13 C
Chamber: 22 C

Needless to say that in the last few hours did not print.
I think everything was fine before the last firmware update? Does anyone else have this problem?

Best regards, Peter

Same here. Problem was there with the previous firmware version, too. It was just not visible because the printer heated bed and nozzle to 25 degrees after start up.

I have high precision temperature measuring equipment on hand, so I recorded some values:

shown on printer / measured middle of bed / difference
08 / 18 / -10
20 / 24 / -4
30 / 30 / 0
40 / 38 / +2
60 / 52 / +8
90 / 75 / +15

So “they” know about it and were just faking by heating up the bed after power on?

Maybe - maybe not. I don’t want to accuse anyone prematurely. I think it’s best to open a support ticket and see what they answer. But I will wait till christmas is over…

I see the same on both my P1Ps, too. This is a screensnip from Bambu Studio on my Mac with the printer at ambient printer after not being used overnight.

My P1P has been standing for 18 hours - no problem here X1C is printing so will check what happens later - All machines running on latest firmware
