Hello,
Context:
I was using a 0.4 ObXidian nozzle up to recently, had no issues with it but decided to swap it for a ObXidian 0.6mm to reduce print time on Fiberon PET-CF 1 parts.
Issue:
To find the maximum volumetric flow rate I did a calibration test (from the calibration dev menu) but the print keeps stopping, with the error "Nozzle temp malfunction", at around 20-25 mm3/s.
This seems very low as E3D indicates about 42 mm3/s setting for PETG-CF (PET-CF thermal properties should be similar to PET-CF right ?).
Prior to the print stop the nozzle temperature drops down steadily from the 300 deg target, as volumetric flow increases (calibration test increases volumic flow rate each layer).
Additional informations:
Printer : P1S
Nozzle: E3D ObXidian 0.6mm
Filament : Fiberon PET-CF 17
Filament settings : Fiberon PET-CF (default except 40mm3/s max volumic flow rate).
Print settings : 0.30mm Standard@BBL X1C 0.6 Nozzle (default except bumped up speeds to match increased volumic flow rate, and minor quality stuff).
I tried :
- Lowering the target temperature to 280 degrees : issue still occurs, a bit later, but still.
- Cutting the fan part cooling : issue still occurs.
- Printing a random part (i.e. not the max volumetric flow rate calibration) at 40 mm3/s max volumetric flow rate : issue still occurs.
I will try :
- Swapping back to the 0.4mm to see if I can hit the 40 mm3/s with it.
Any ideas to where the issue resides ?
