P2S and PETG-HF works great!

I have 6 P1Ss that I’ve had since they first came out. I always had difficulty with PETG with about a 30 to 40% failure rate (have about 3,000 hrs on each). I decided to purchase a P2S with the express purpose of dedicating it to print PETG-HF. Did some research including reading about issues on this forum so I purchased a High Flow hot end as well.

Changed the hot end, dried the filament in the AMS 2 Pro (moisture was down to 8% when done), and did the flow calibration (automatic, not manual). Using the stock textured plate. Also, used the default profile. Did a test print and noticed that the first layer had some small gaps between some of the layer lines. Adjusted the first layer flow volume to 1.05 and tried again. Perfect! First layer looks exceptional, no gaps clumps or bumps. The rest of the print looked amazing as well. No adhesion issues and parts came right off after I let it cool for a few minutes. Tried 3 different models, all with unique first layers and all came out perfect! Hopefully this keeps up, if so, I’m switching over all my machines!
Great job Bambu Labs!

I can confirm that the PETG-HF works flawless my on my P2S, with stock settings (and nozzle) , though I use an AMS-HT to store/feed/dry it, so that I can use the AMS 2 Pro for PLA.

When printing PETG-HF, are you using a HF nozzle?

4

Yes, I purchased one with the P2S. They seem to have less clogging issues per what info I could find online. Standard nozzle might be fine, but this is working great so far.

5

Are you using a .6 nozzle with the High Flow setting?

6

Not sure where you saw that, but in my experience the opposite is true.

So far it has worked great! Absolutely no issues and prints are coming out perfect. I’m using this as a production machine so time will tell. I’ll post if anything changes.

No, I print with a 0.4 nozzle but keep the nozzle setting to standard in the slicer.

10

Your experience is that a .6 nozzle clogs more than a .4?

11

I’ve only ever printed with a 0.4 mm nozzle.

12

Yes I haven’t had any issue with PTEG-HF. Bambu brand and stock settings and hotted. Love this printer. I think most problems come when people start changing things, then end up with issues.Just sayin. Great machine though.

I used Creality PETG with the 0.4 and it made a wonderful Giant print. Took up most the bed and height. No issues default settings. Note I did have a 45 degree internal air deflector attached that I printed due to the fan cooling the bed temp too much.

I’m printing several projects with a P2S, 0.4 Nozzle, and using 3 colors of PETG-HF. The results are excellent!

Did you print with a .4 “HF” nozzle? Thanks

17

Yes, using a 0.4 HF nozzle.

18

I’m having trouble with spaghetti. Using the Nozzle and plate that came with the P2S. Filament was dried and humidity is 5% in t AMS 2 Pro. New to 3D printing so still learning.

19

What filament are you using? Can you post a pic?

20

I got the same question. I haven’t been able to get .4 hf to print right with petg hf.

Can you post a pic of how it’s printing
