Rapido 2 ADC out of range
Installed a Rapido 2 Plus and get a klipper shutdown nearly instantly.
printer.cfg contains an override of
sensor_type: PT1000
The enabled hotend config is [include config/hotends/rapido.cfg]
Previous hotend was a Rapido 1 (not Plus), (that had a damaged wire, thus the upgrade)
e: It has been mentioned that it's possibly a bad crimp job. Don't know how to test that

Upload your printer.cfg
you can try adding this to the user overrides section (be sure to remove it later)
then it should show in the mainsail interface which one has a negative value (and thus is broken or not connected correctly)
Your config looks fine
max temp of -120 for the bed?
raising the max temp further,
Are you sure that the rapido 2 thermistor you have is a pt1000?
Ohh, that should be min_temp. I copied it from another post and they needed it as max temp but in this case you want min temp
Fairly sure,
although it may indeed be physical: if I push down on the sensor when it is removed from the hot end,
What sort of connector is this? Is this even fixable on my end or is it a $100 piece of trash out of the box
It a thread in pt1000. Probably a common metric thread (I don't have one so I can't measure it for you).
It fits an M4 nut (and screw on the other side)
Does that mean I can replace it with any M4 pt1000?
e: also if I can find 2 pin molex connectors and the crimp terminals
oh! it wasnt attached at all
the spring was the only thing holding it on the wire
yeah, any pt1000 will do
good to know, I doubt any local store sells something that specific so rip weekend plans lol
This also seems incorrect
What thermistor did you replace it with?
Excellent question, because it was what came up when searching PT1000,

Well that's your problem, it's not a pt1000. It's a k type thermocouple which requires a amplifier

Get one of the types mentioned in
sensor_typeI will look into finding one of those that fits the threading of the rapido 2, thank you
Thanks! That's the one I'm lookin at but I've also started the return / replacement process in the meanwhile
another two week delay though, painful
