Heater extruder not heating

Hi all again,
I can't seem to heat up the hotend on the vcore 3.1 I am trying to finish commissioning.

When I do the PID tuning for the extruder (the stock Phaetus Rapido), or when I just try to raise the temperature from the console, I always get this klipper 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 am using the default conf for the hotend:
[extruder]
dir_pin: !e_dir_pin       # Remove ! in front of pin name to reverse the direction of extruder
rotation_distance: 5.57   # Bondtech LGX Lite default
#pressure_advance: 0.05   # Check https://www.klipper3d.org/Pressure_Advance.html for pressure advance tuning.
control: pid
pid_kp: 28.413
pid_ki: 1.334
pid_kd: 151.300


I checked all the cables and they are not broken, plus if I hold a lighter under the extruder I can see the thermistor is registering an increase in temperature.

What can be wrong? 🙏
