Including pictures and detailed information about the print speeds, filament type and settings used will help get the appropriate solutions.
Hello, I have some PTEG inland filament, and I run first layer at 245C and the rest at 240. It says recommended temp is “220-240” I get a lot of stringing and “bumps.” I don’t know what your PTEG settings are but mine are just the Generic PTEG settings switched to 220-240.
Before adjusting settings, I’d suggest drying your PETG. It may not be as hygroscopic as Nylon, but it can definitely pickup moisture in the air and start causing these issues you are seeing. Even if the filament was freshly opened it can still have moisture from the factory.
As for the recommended temperature, those are really just a suggestion, typically targeting much slower printers. I usually keep the higher temperatures that Bambu has in their profiles since it prints quite a bit faster and it flows better with the higher temps. If you are still seeing issues after drying the filament, you can try printing a temperature tower to find what works best for this particular filament.
The common causes include: Over-high Nozzle Temperature: If the hot end temperature is too high, the filament will be more fluid and more likely to drip out of the nozzle. concensus of opinion i found on google
Then you’ll want to follow my other suggestion and print out a temperature tower. If you are using OrcaSlicer you can use their temperature calibration. Otherwise you can download one from MakerWorld. The benefit of the temperature tower is that you can see quality, stringing, and overhang results at different temperatures. You can then use these results to adjust your filament profile to a temp that works best for you.
Then you’ll need to download a temperature tower from MakerWorld. They have instructions on how to make sure the temperatures are set at the appropriate layer height.
One other thing, try to make sure the nozzle is clean before printing with PETG. That stuff is rather sticky and can cause all kind of fun problems as you print. This is just a preventative step and not a solution to your problem.
Add another plate and print it seperatley ( the pole ) if its a seperate object (its difficult to see in the gif ) also use a brim to help secure it to the plate , the spaghetti usually follows the printer continuing to print in the area of a failed object , wobbling , fell ,moved
