I believe that there are two versions of the rapido with two different thermistors... Likely you'll need to account for this in your config

Did not know I could do that.

as Sherbs mentioned the Rapido can come with different thermistors. Which one did you get?

I am going to make a logical deduction here and say that it is the older one as the listing and included packaging says nothing about it being a PT1000
blacksmithforlife
And in that packaging what thermistor does it say to use?

Uh its a Rapedo So the thermistor is built into the heater.

I was using a generic prusa thermistor in the dragon hottend i had on here before.
blacksmithforlife
Yes I know it's built in, that's why you need the information from the manufacturer as to what to use for the thermistor. Hint: look at the product description

Ok I can confirm it definitely is a PT1000.
blacksmithforlife
Now you should check the rapido config and see if it is using pt1000

Just had time toninght to look into this gain. Here is what mine has. It says not to modify this file in the header though. I see the min temp is 170C is that my problem?

Or should I just edit it to heater_pin: e_heater_pinsensor_type: PT1000sensor_pin: e_sensor_pin
blacksmithforlife
No need to change the sensor pin or heater pin If you need to change the value, you over write it by putting it in your printer.cfg You only ever edit the printer.cfg file

https://www.klipper3d.org/Config_Reference.html#extruder You also should put it in the USER OVERRIDES section

line 121 you misspelled heater_pin. But you don't need that line at all as you are just repeating the default. So remove line 121 and 123.

You can't just put it wherever you want. They have to go under the applicable section. You just have sensor_type: PT1000. That line needs to go in its proper place, which is under [extruder]

It works! Erika!. So I just eliminated it entirely from the extruder section and just kept the data in the user configeration section.

Thank you for putting up with all my questions. I would have given up on this thing by now otherwise
