#[SOLVED] ADC out of range - PT1000 problem

Hi, I've got a problem with my Voron 2.4 new setup - Manta M8P + EBB SB2209 CAN on RP2040. I have a ADC out of range, with my PT1000. After configuring my printer.cfg, chcecking the Hardware ( measure the termistor - its working, and setting a switches in good positions) I still have this problem. Can anyone can help me and told what I'm doing wrong? I tried to setup a printer with TH0 (of course making a good config and hardware for this replacement) - same effect, ADC out of range. I also tried with different termistor - but still the same . I will be thankful for help 🙂

my printer.cfg :

Where is the max plugged in?

#

And can we see a klipper log?

#

max is built into the sb2209, the only problem with config is rtd_nominal_r: 100 rtd_reference_r: 430 is supposed to be 1000 and 4300 a picture of wiring just incase would be great

  1. The max31865 has its own set of error messages, not adc out of range
#
  1. Your log shows perfectly sane temperatures on the extruder
#
  1. We see crazy readings on something called "buildplate"
