Problem with printer configuration - PT1000 sensor, motors not moving

General Discussion
1

Hello,

I’m currently working on my printer configuration but I have a few issues that I’m stuck with.
The main one is configuring the heater sensor, which is PT1000 - on octoprint page temperature shows enormous values like 14 million. I guess I have some parameters missing, but I can’t find any of them.
Another problem is that motors are not moving when i’m using control tab in octoprint page. After some tries i get:

No response from printer after 6 consecutive communication timeouts, considering it dead. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves.
Changing monitoring state from “Operational” to “Offline after error”
Connection closed, closing down monitor

Can anyone help me with this?

See Documentation; add `inline_resistor` to PT1000 section? for a discussion on this topic.
You could try to set inline_resistor: 4740 or whatever your board requires as pull-up resistor

Thank you for the reply. I don’t really get how can I set inline_resistor value, I don’t see any pieces of information about it in the link that you added. I found that my board has 10k inline resistor, but still I can’t figure out how can I include it in my config.

Have you tried:

heater_pin: !PA20
sensor_type: PT1000
inline_resistor: 10000
sensor_pin: PC15

Yes I’ve tried, and every time I do that I get

Option ‘inline_resistor’ is not valid in section ‘extruder’
