Heater extruder not heating at expected rate
Whats the most common/prolific cause of this? 😦 Got an urgent job and this is killing me Klipper reports: SHUTDOWN
Heater extruder not heating at expected rate
See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.

I'm wondering if its because I have recently been tinkering with the new "Dynamic fan speeds" feature and the part cooling fan has been interfering with PID?
Managed to pull off 4+ day prints without issue previously, only changed have been RATOS updates and tinkering with "Dynamic fan speed"
Nope its just done it before the print even started during bed probing, I guess its more cable fatigue 😦

most often, cooling fan overloads the hotend
ah yeah, that sounds more plausible then, connector or cable unfortunately

Its not the fan regretfully 😦 Just did it prior to a print starting
Any idea where the klipper log is, would be awesome if it provided more detail. Thermistor or heater cartdrige

in the "machine" tab
bottom right, you have both klipper and moonraker

Thanks
Just reset it and waiting for the next failure now
Too much info

it triggers really quickly if there's a short, so you can wiggle the wires around and look for when it shuts down

Hmm....
Could also be a faulty thermistor
@Folkestone3DPrinting hi did you fix it i have the Same Problem
I had the same problem. It was the hotend socket that made a bad connection. I cut the plug and soldered the wires directly. After that it work perfectly.
Solder connections on something that moves is an accident waiting to happen. The solder will eventually break. Crimped connection is industry standard for a reason
