QIDI Q2 showing 360°C while cold / won’t boot after filament blob removal
Hi everyone,
I’m using a QIDI Q2 and ran into an issue today.
During a print, filament built up around the nozzle (likely failed adhesion). While removing the filament blob, a firmware error suddenly appeared.
After that, I removed almost all of the stuck filament and tried:
- Restarting firmware
- Rebooting the printer multiple times
- General troubleshooting/restarting
Now the printer won’t boot properly.
The strange part is that the nozzle is completely cold, but the screen shows around 360°C.
I also noticed that one of the wires near the hotend/nozzle area may have come loose or detached while removing the filament.
Has anyone experienced this before?
Does this sound like a thermistor/wiring failure, or could it be something else?
Would this usually require replacing the thermistor/hotend assembly?
Photos attached. Any help would be appreciated.
