Hello,

It was not a problem of sensor or connection but a problem of motherboard. I changed the motherboard and everything is in order. With the same sensors and even connections.

Problem solved.

Hello,

Problem solved.

I tried by unplugging everything from the motherboard and flaming the firmware.

Always the same problem. view the photo

hello, I have the same problem,
at startup, the panel displays 254/0 - 144/0
while the bed and the nozzle are cold.
So impossible to start an impression
If I unplug the bed and / or the nozzle and their thermistors from the motherboard, I have the same problem ...
I also checked the thermistors ...

I also checked the thermistors, they are OK.
We will say a motherboard problem but I do not know how to identify it.
