Basic Information:

Printer Model: Kobra 2
MCU / Printerboard:Trigorilla_Pro V1.0.2
Host / SBC PI4

After klippy (2).log (2.1 MB)
Before klippy.log (4.3 MB)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…Both heaters stopped working on Sunday I have upgraded & downgraded Klipper. Reinstalled klipper . Not hardware issue as I tried marlin both heat. Don’t know what to do. Please help

Heater extruder not heating at expected rate
Transition to shutdown state: Heater extruder not heating at expected rate
See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check.

is to 99.99% a hardware issue.

extruder: target=200 temp=18.9 pwm=1.000

When the extruder is is set to 200°C and the PWM is at 100% but the temperature stays at 18.9°C. there is a hardware issue.

You may triple check the wiring, the output of the printer board, the PSU etc.

Hi been there done that . Both will heat in marlin software so that’s why i think it is something else. All movement works Thanks

Solved This board you need a value on Output pin section then the heaters work. they worked before with a static value which i removed.
[output_pin power_ctrl]
pin: PB4
value: 1
