### Basic Information:

Printer Model: Ender 3 v2 Sprite Pro Extruder  
 MCU / Printerboard: SKR Mini E3 V3  
 Host / SBC Raspberry Pi 5 4GB  
 klippy.log

Hi everyone,

I’m running Klipper on my Ender 3 V2 and recently swapped in an SKR Mini E3 V3. When I try to heat up the hotend or heaterbed, I get the following error:

**“Heater extruder not heating at expected rate  
See the ‘verify\_heater’ section in docs/Config\_Reference.md for the parameters that control this check.”**

I’ve double-checked my configuration files, but I’m not sure what exactly is causing this issue. Has anyone encountered a similar problem? Any advice or other troubleshooting steps would be greatly appreciated.

Thanks in advance for your help!

Klipper is correctly:

- Setting the target temperature
- Setting the output to 100% (PWM = 1)

However, the actual temperature is not changing at all. This issue is likely due to:

- A defective heating cartridge
- Problems with the wiring, such as broken wires or a defective connector.
