Issues upgrading V-core3.1 to toolhead v1.0

I am upgrading my v-core 3.1 to a toolhead 1.0 (orbiter 2 + rapido 2 + EBB42 1.2) following a print failure that destroyed most of the printing head. Both the main board (octopus 1.1) and the toolboard (EBB 42 1.2) show as "detected but not responsive" in the configurator. I have eventually updated the firmwaare by SD card but the firmware on the toolboard doesn't seem to have been updated. Currently the hotend temperature sensor (PT1000 from a Rapido 2) is reading temperatures around 150 million degrees Celcius. (it fulctuates) I've manually changed the max temp to above that to be able to actually start klipper (not turning the heater on, obviously) . sensor is set as sensor_pin: toolboardd:PA0 and sensor_type: PT1000. I use this printer for work and would greatly appreaciate any help as I have late orders I need to produce urgently. What do I need to do to get a proper reading on the hot end temperature sensor? (to me it looks like an open circuit but I don't know how else to set the pin for the sensor) side question: Do I need to connect the Super Pinda probe to the main board or toolboard? I've seen both in several documentation. Does it matter where it is plugged in as long as it is set as such in printer.cfg? Thank you in advance.

Order is important (https://os.ratrig.com/docs/configuration/includes-and-overrides) so you tried to set the sensor and then it gets overwritten by the lower toolboard include. You should instead be putting things in the USER OVERRIDES section
Includes & Overrides | RatOS
RatOS uses a modular configuration that heavily takes advantage of the config file include and merge logic in Klipper. For this reason, the order of includes and overrides are very important, do not change the order of the configuration unless you know what you're doing.

Thank you. it makes sense. I have corrected it but still have the same issue. I plugged in an old rapido with PT1000 that i have and temp is now down to circa 360°C

still not good but closer to target I guess. Kinda worrying that the one that gives 5 times the temperature of the sun is brand new, received from Ratrig this week

are you sure that the wiring is good and that it is actually a pt1000?

the thing came out of the box on Saturday. I see no damage to the wiring and it is labelled PT1000 (pictures coming in a minute)

so... wiring was damaged the wires are way too thin to be crimped. I extended them with thicker gauge wires that now survice being crimped it brought the temperature to 365°C

turns out that removing said jumper does solve the problem the picture shown is not a v1.2
blacksmithforlife
you might need to change the sensor pin to enable a pullup when using that jumper. Try it without the jumper and see how that affects things

without the jumper it displays the same temperature as the bed

@Cruz you might want to update the guide in regards to the jumper. Perhaps you need to update the printer.cfg if using the jumper?

Not sure I follow
blacksmithforlife
https://ratrig.dozuki.com/Guide/12.+Electronics/250?lang=en#s2564 talks about adding a jumper to make the temp more accurate. But as you follow the thread above, that is not the case and it caused confusion. I believe if you add that jumper you need to also change the printer.cfg

If you select the right hotend in the RatOS configurator you don't have this issue the jumper must be inserted

he isn't using ratos 2.1 as he is still on vcore 3.1

there is no specific instructions for the wiring and it refers to the Vcore 4 ones maybe it needs specific instructions for the upgrade kits Thank you for your help @blacksmithforlife , i'm back to work.
