My first attempt with Bambu PETG-CF on my new X1-Carbon did not go well. I installed the 0.4 Hardened Steel nozzle. I dried the brand-new roll for 24 hours on high in my PolyDryer (the dryer is supposed to be right around 70 C) and then direct fed it into the X1-Carbon (not using the AMS). I used the default settings in Bambu-Lab for PETG-CF.
I know that the 0.6 Hardened Steel nozzle is recommended for PETG-CF, but the detail on these parts made me think it should be printed with the higher resolution nozzle.
There were little bits of detritus all over the plate. The pieces that seemed to print OK break in half. The nozzle looks clean though. Can someone with experience tell me how to get better results? Are there specific settings that I should change, or is this simply the best one can expect from the 0.4 nozzle?
I don’t have experience with Bambu’s PETG-CF, but I do have experience with Bambu’s “recommendations” that should really be requirements…
I thought the same thing once when working with a Silk filament. It is “just a recommendation” I thought. Turned out to really be a requirement as my results were not what I would have expected. Now I view “recommendations” from Bambu as “requirements” when working with many of their products.
No. Lol. I’ve never heard of that (I’m new), though I could see why it would make sense. But since I dried it for 24 hours, isn’t the culprit likely to be some other problem? Nozzle diameter? Print speed? etc…
You get a lot of retractions on those open frame designs I guess… That can cause the temperature in the heatbrake to creep up, increasing the chance of blockage.
Might be that that causes the nozzle to jam. Might be worth it to print them one by one to get printing time down and not let the temp creep up blocking the nozzle.
