Idex upgrade, "ADC out of range" - is there something wrong with my Rapido?
Hi, not sure if correct section to ask this, but here goes (please be kind on me for not finding anything by searching and using wrong names on stuff, I'm trying my best as a noob :-P).
I got my hybrid to IDEX kit from Rat Rig and have a problem with "ADC out of range" on the new Rapido.
I noticed that the new one is different from my old one, but not sure if this is a fault or a design change.
The old one looks like it has a detatchable PT1000 (?), the new one seems to be missing this part. The old one has wires going into the detatchable part, the new one goes directly inside the hotend.
Attatched pictures explains this a lot better..
With the cable connected it has a sensor reading of -255.443, when the cable is disconnected it has a sensor reading of 65707422.561. So there must be some kind of connection.
I tried using a cable to connect the new one to the old one EBBboard, with similar results.
I'm hoping it's not a faulty part and just a different version or something, and that it can be solved by changing a setting - maybe something in printer.cfg similar to this?
[extruder1]
sensor_type: PT1000
pullup_resistor: 2200
Added my klippy.log for both with and without attatched cable, not sure if needed.
Any advice is highly appreciated

I had a similar issue, but not idex. I changed the pullup_resister value to 4700 and that fixed it for me. I think there is a more proper way to correct this, but this is what worked for me
If the pullup resistor change doesn't help, i'd double-check the wiring to the thermistor. From your testing with the cable connected/not connected it reads like there is a short in the cable.
