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 Klipper message:

MCU 'mcu' shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

Upload your printer.cfg

printer.cfg

you can try adding this to the user overrides section (be sure to remove it later)

[heater_bed]
max_temp: -120

[extruder]
min_temp: -120

[heater_bed]
max_temp: -120

[extruder]
min_temp: -120

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?

DeckerOP•2y ago

raising the max temp further,

blacksmithforlife•2y ago

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

DeckerOP•2y ago

Fairly sure,

DeckerOP•2y ago

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

blacksmithforlife•2y ago

It a thread in pt1000. Probably a common metric thread (I don't have one so I can't measure it for you).

DeckerOP•2y ago

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

DeckerOP•2y ago

blacksmithforlife•2y ago

yeah, any pt1000 will do

DeckerOP•2y ago

good to know, I doubt any local store sells something that specific so rip weekend plans lol

DeckerOP•2y ago

This also seems incorrect

blacksmithforlife•2y ago

What thermistor did you replace it with?

DeckerOP•2y ago

Excellent question, because it was what came up when searching PT1000, https://www.amazon.com/dp/B07BW7XCB2

Well that's your problem, it's not a pt1000. It's a k type thermocouple which requires a amplifier https://www.klipper3d.org/Config_Reference.html#common-thermistors Get one of the types mentioned in sensor_type

I 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
