Nice. Was that your actual printer, or just one that you found on YouTube?

That was my print from last night, took 8 hours.

Nice.

I like how your printer does the video. Most printers that I have seen move the print assembly out of the way to take a picture, but it looks like yours does not. It seems that this way of doing the video would not slow down the print job. Does it work that way, or does creating the video slow down the printing?

I don't think it slows down. I slowed the print down since it's in my bedroom, to keep it quieter.

Well double print fails today, first one little pasta going on, not sure why, maybe cause the fan was making little loose n was making.some noise. Held on by magnets... Second was my Bronze PLA brittle n broke in the tube. Any tips ro aalvage it? Put in my filament drier 40° at 6hrs, maybe that'll help, idk... printed more parts for my Master Sword, tried using the Bronze for grip wrapping n some other parts n broke practically as soon as print started... Might be good idea to pin my old printing tips post so we can all add tips. Just a thought.

*BEEEEEEEEEEEEEP!!!!!........* 3 failed prints in 1 day.....

Yes, a vac job was needed.....

I'm absolutely amazed at how much the inside of the P2S looks like your ELEGOO unit. Even the printing plate.

Yeah good bit actually, and correction 5 prints, 3.5 fails.....

@Chris Savage @granz @MicroNut
Ok, question time.... My spool of Inland Silk PLA Silk Blue-Silver 190-220 / 25-60, from the Benchy works FLAWLESSLY, except for my very first fail, just 1 spot didn't adhere, but my roll of HS-PETG Clear 220-260 / 60-80, just will NOT work correctly.... ALL fails, except for some parts on the 2nd attempt of clear printed several parts, but keeps failing reguardless on the Centauri Carbon.... I got said spool on my Neptune 2D, and it's working.... ANY suggestions?? Also my Bronze PLA, I've had in my drier for 8+ hours and is still brittle, lost cause to keep it or there a way to fix it??

Chris Savage · Jul 19, 2026, 03:40 PM

Are you (is your printer) using the right profile for PET-G which has different temperature / speed than PLA?

granz · Jul 19, 2026, 04:49 PM

That was my thought, too. I believe that PET-G has a higher temperature requirement than PLA. That could account for it not sticking properly to the bed/plate.

As far as the bronze PLA, I don't know about that. I did, however, find a thread on Bambu Lab's forum where they discuss this. Some of the people suggested that removing several feet of filament may allow you to get to a part of the spool where the filament works properly. You can take a look at that thread for more info. I reached that by doing a search for "bronze pla filament too brittle" - maybe you can find somewhere that has other suggestions that might work.

Well here is the PETG, Temp set to 230 / 60 & 70, started printing n first layer warped due to heat.... as for speed, it's whatever Elegoo Slicer Centauri Carbon 0.4 with the default filament.... idk.... Just finished FINE on the Naptune 2D...

I can remove several feet n try that. Thanks.

Well.... Neptune 2D print failure, but for a different reason, need to reprint like 105%, goes over the handle, but is tight, so think like 105% good start, just print a bit, stop n try it.

granz · Jul 20, 2026, 07:31 AM

I was a bit surprised that you had deleted the URL for that Bambu Lab thread about the brittle filament from my comment - then I realized that you had not deleted it, but that I forgot to include it.

Sorry about that - there is some more information, and other ideas there. You may want to take a look at that thread, along with looking at other search results.
