HMS_0C00_0200_0002_0006: Nozzle too high
The detected nozzle height is larger than the stored value. This usually caused by accumulated filament residual around nozzle tip.
Check if there is filament residual around nozzle tip.
Remove the residual filament if there is any. Heating up the nozzle might be needed.
Restart a print job and see if the error message disappears. If not, run a calibration.
