I have been trying to print PETG-CF on an H2D but, after less than 20 layers, the printer pauses the print with the error “Your nozzle seems to be covered with jammed or clogged material.” If I resume it or even disable the AI monitoring entirely, the print does come out badly.
I have tried different spools and different prints to see if it is for some reason the model. The print does work just fine on an X1C.
The H2D does work just fine with doing the same model out of PETG-HF.
I haven’t printed PETG-CF on the H2D yet, but I have been working with PC-CF and found it necessary to adjust the Z-offset for my filament brand.
The new firmware may include updated Z filament type settings, but I haven’t had a chance to test the beta version yet I’m still on the waiting list.
Using H2D firmware 01.01.01.00
PETG-CF is a bit too sticky which is why it would stick on the nozzle. If you’re printing with a low layer height (especially when lower than 0.2mm) , you’re highly likely to encounter problems like this, as the nozzle is pressing on the filament hard.
Other things you can try is to slightly reduce flow rate, or reduce the volumetric flow rate, and also reduce the infill/wall overlapping settings.
Thanks for the quick response!
I tried adjusting the z-offset a bit and increasing the layer height. I think the z-offset might have helped a little because the print made it further, but it did succeed.
I am going to try to continue to adjust the z-offset, but I could not find out how to adjust the flow rate.

Cool - you just need to find the sweet spot for the CF filament and the bed plate you are using.
Samples:
G29.1 Z{0.05} ; For the CF Smooth PEI Plate Adjust in 0.01 steps up or down to fine tune
G29.1 Z{0.10} ; For the CF Smooth PEI Plate, you may need to make some fine adjustments in 0.01 steps up or down to this value
For the texture plate the oem defaut is -0.02 so you might have to go up to 0.00 or like 0.01 fiber filaments have different effects sometimes.
Some carbon fiber filaments can be printed effectively with layer heights as low as 0.16 mm. However, it’s generally safer to use slightly higher layer heights with a 0.4 mm nozzle just proceed with caution.
Keep in mind that the firmware or filament settings might be updated in the future.
I’ve had no trouble at all with Tinmorry PETG-CF. I’ve gone through nearly a full roll so far.
Could it possibly be the filament? I don’t want to be that guy, but did you dry it? The funny thing is, those prints are using undried filament.

Cool 
Yeah, I think it’s a good idea to start sharing the brand of filament being used.
I’ve tested various filaments in the past years, and honestly, I haven’t always been impressed regardless of whether they were expensive or cheap. Sometimes the cheaper options actually perform better.
Each brand seems to have its own distinct and proprietary formula for its filament type, and certain filaments tend to perform better depending on the specific extruder or hot end in use.
Enjoy your 3D printing!
Ich habe weder mit PLA, PETG (CF), ABS GF, (alles von Bambu) noch mit Mehrfarbdruck Probleme. Die Druckqualität ist gegenüber meinem X1C auch besser, was ist bei euch los.
Ich benutze das letzte offizielle Firmware-Update.
Grüße
I am using Bambu lab filament, and the same exact spoon worked just fine on the X1C
