Crappy filament? (lemmy.world)

Not sure if anyone has seen this before but I bought two spools of PETG from Elegoo, one in white and one in black. Their regular PETG, not the rapid one.

Yesterday I printed with the white spool and it worked pretty well.

Today I tried to print with the black spool and the filament would not come out of the nozzle. I tried diagnosing the problem and ended up swapping nozzles, taking apart the nextruder and putting it back together. Then I tried printing again and again the filament would not come out. I swapped back to the white filament because at this point I've essentially ruled everything out except the filament and the white filament worked. I then tried the black again and it would not print. I cut off about 10cm of the filament and tried again and same issue. Finally I cut off about another 50cm and now it started to print.

I'm not sure if this has happened to anyone else or if anyone knows what the issue is. It's almost as if the filament refused to melt or had an much higher melting point vs the rest of the spool.

@idunnololz Elegoo PETG is simply horrible, never again. It surprised me a bit given how awesome their PLA is.

PETG really is variable from suppliers. It ranges from easy as PLA to unprintable.

Will try a different brand once I'm done this spool. The weird thing is the white filament was perfectly fine. Maybe just some impurities or something.

Not sure how my experience stacks up but I have been getting performance equivalent to the Bambu PETG out of the Elegoo I have been buying recently on my P1S. A little bit of stringing but that seems to have a lot to do with recent humidity as a pass through the filament dryer has been rectifying it. Just ran 2 rolls of the Red PETG Rapid through for my mates packout accessories, and before that I did a bunch of cleats for his tool wall in some Black PETG.

Did a good enough job that he rather kindly bought his wife a P1S for her birthday when the Black Friday sales hit. She has turned that around and run the printer non-stop since it arrived and only about 40% of that has been prints for him. 😆
