Bambu P1S print problems - need help

[adbuch]

My new Bambu P1S started out fine when I printed several of the pre-loaded files (Benchy and Storage Tray with lid). I was really impressed with the print quality.

Then I immediately printed a simple 2" flat washer with " center hole that I drew up with Fusion 360, imported to Bambu Studio and sliced using the stock Generic PLA settings. The print failed and ended up with the nozzle dragging the part around the build plate. I suspected that this may have partially clogged the nozzle. I extruded quite a bit of filament manually thru the nozzle and then did a cold pull following instructions from a Youtube video.

I then loaded the same filament that I had started with. This filament was brand new from the sealed bag. Also the humidity here is usually under 10%, and I have never had a problem with wet filament with any of my other printers.
I am looking for suggestions as to what may have suddenly changed that could be causing my problems shown in the attached photos.

Thanks!

David

Well It LOOKS like plasma table owners are drifting off to other processes now. I am into 3D printers, and lasers, and cnc routers, etc. Here is a post about a 3D printer.

I see no problem with it, except that I am not sure the admin wants to "branch out" to other processes HERE. The thing is, cnc plasma tables are going the way of 8-track players, and CB radios, and VCRs. As prices come down, more and more people are looking to turn their backs on Fred Flintstone, and look to George Jetson for guidance

I think there is room for sub boards that cover other topics ... NOT POLITICS! ... but other topics of interest to the many users of plasmaspider.

I myself am guilty of drifting away from plasma, because I have not cut anything on my table since the covid zombie apocalypse of 2020. I am planning to get back to it, and get my Samson table cutting again. However, time marches on, and I am currently lining up $400.00 per cut hour jobs on the laser, so ...

FYI, there is a forum dedicated to 3D printers ... it is called

Well David that is a head scratcher, looking at the 4th image down the pre-extrude at the edge of the build plate the filament is acting correctly. Then for it to go off the rails in the print area and the other prints looks like maybe a contaminated section in the roll from the factory. The last Benchy really look like very wet filament, but not from your environment. In the same image the separation of the print again could be not bonding/melting together of layers. I would watch the hotend temps to see if they are fluctuating any amount.
Interesting the slicer I am using uses generic setting from my Anycubic vyper printer without a problem, and yours worked very well with the setting you used to start with.

If Admin didn't want discussions about 3D printers, he wouldn't have created a separate category called "3D Printers & Printed Accessories".

Tom - yes, the first 2 prints came out perfect. I doubt there is a contaminated section in the brand new roll of filament. Hotend temps stay perfect. I tend to think this is a mechanical problem of some sort. I will step away from it for a while and give it some thought.

I think you have one of the Anycubic printers. I just ordered one from Amazon to try it out. It's nice that they have a 30 day return policy.

Yes - the Anycubic Next Slicer look very much like the Bambu Studio slicer. What slicer are you using?

I have been using Ideamaker for some time, It is put out by a manufacturer but it will add other brands to the slicer. It is setup so when I click on a STL file it auto starts to Ideamaker for slicer planning. It is free, after you add your printer you can edit the setting if you want as with other slicers.
I use WIFI to sent the G-code to the printer via Octo-Print, or you can use a SD card to plug in the printer with the G-code.

Tom - thanks for the information on your slicer. I will have a look.

Hey Tom,

Im sure I can help with this if you've not figured it out yet. Ive got a Bambu P1S too - they are awesome, good choice.

The good news is that there is more than likely nothing wrong mechanically with your machine and it should just be a few settings that need changing in Bambu Slicer. In reality the machine should work perfectly out of the box, so my guess is that you might have accidentally nudged a setting that wasn't quite right and its thrown everything off.

Try this:
- Import your file into Bambu Slicer as you normally would,
- Save it out as a '.3mf' file. (File > Save Project As)
- Attach the file here.

Il take a look and see if I can spot anything obvious.

Few questions:
- Are you using Bambu Lab branded - PLA Basic Filament?
- I assume everything else is as it came in the box?

All the best,
Sean Drummond

HI Sean
I agree with your statement, I don't think David would have changed any setting and had printed successfully before the event.
That is why I looked at a failure or bad filament as the problem and was waiting to see how it turned out.
The only time I have had separation like that was from the filament itself.

The file (stl) prints fine on my other printers - so not a problem with the solid model. Yes - Bambu filament and the first 2 prints were perfect. After the failed washer print, the first 2 files no longer print well. See my picture of the benchy. I have swapped out the nozzle with an new one and still having problems. I have stepped away from this project for a bit to focus on other projects, but when I return to it I will report back with any updates. I posted this at some of the Bambu and 3D printing groups and no one really had any constructive ideas. Lots of "clean your build plate", "wet filament", "clogged nozzle", etc.

When you get back to it have you moved the filament from the Bambu to your other printer. I don't see the build plate as a problem, as things look like they are sticking at the start. Even the benchy which has a smaller foot print to hold on to the plate.
I'm stuck on bad filament. As you have looked at the extruder temps so I don't see layer separation causing the problem
