P1S Combo - New user printing problems

[Theeym]

Hi there,

I just got the P1S AMS combo as my first printer. I always wanted to get into this hobby and thought this would be a great learning tool.

Now, as a noob, I’m struggling more than I would like to admit!
I have only had this thing for a day so far and my prints are coming out messy.

I have done all the calibration tests from the printer’s built-in and Bambu Studio ones.
I’m unsure if this is either a bed adhesion problem or if the nozzle is scraping away the filament.
The first layers are usually all perfect but as the print carries on it gets more and more stringy and I have seen it just push away the filament it laid earlier.

I am using the stock Bambu basic white PLA at the moment
I’m unsure if maybe I’m doing something wrong or having some really bad luck.
Any help or tips would be greatly appreciated!

Below are pics of the current prints I have finished, including the calibration tests.

It’s also throwing the filament bits around the bed and onto the bottom which I’m worried may cause a blockage at some point.

This was the first flow dynamic calibration I did.

Then attempted FLow rate. This is where issues began to show more clearly. -10 was not smooth but the nest out the bunch.

I ran the second part of the test and this was the result. It looks like either it’s not adhering to itself or pulling itself away.

After some time I ran the calibrations again and these were the two prints that managed to finish.

Other things I have attempted are:

• Clean the build plate with dish soap
• reset it to factory settings
• Used a bench model that didn’t come on the microSD

Hi,

I would start with basic things, check if you set up properly the printer, nozzle, build plate and filament types in Bambu Studio.

Filament → if it’s brittle it’s wet and needs drying.

If this doesn’t help, I would do full filament calibration in Orca Slicer.

Calibration

That’s all what I can think of at the moment, based on my little experience.

I never had to calibrate my P1S when I got it and still haven’t after 150 hours. I would dry the filament, clean the build plate with IPA and use the glue stick provided if you still have issues.

Can you double check that and make sure it’s not the “Support” Filament?

[JonRaymond]

Yup, I think you’re on the right track here. It’s happened to others.

@Voytek89 - Thank you for your help! After doing some research I stumbled on the Orca slicer and there is more in-depth calibration. I’m currently using Orca and was able to calibrate to a much better print quality. It’s still early days (Day 2) but it’s a great start!
My filament is fresh out of the package and I threw it in the AMS with the desiccant I had bought just in case. It’s fairly flexible and doesn’t feel brittle at the moment but maybe I’m unsure how it feels.

@dean448 - Thanks for the tips. I read through several posts and it seems several people were having the same issues as me so I followed a few suggestions. The filament seems fine and I’m only printing in PLA at the moment before eventually moving to ABS but I want to learn gradually
My printer didn’t come with glue but I had better luck after washing the build plate again and using a rough clean brush. I was being too careful at first I suppose.

@xsynatic - I legit thought that was a joke or meme… Turns out I might have been using that all along
I’m currently 3 hours into printing a poop chute for the printer now so once that’s done I will pull out the other filament I have!, Thanks for the heads up

@JonRaymond - So I have also gone and downgraded the firmware to 01.04.02.00 since a lot of posts I have come across have mentioned there “could” be a problem. Now I know that’s pretty extreme but it’s all part of that learning curve I’m after. So far I’m unsure if it’s done anything but it’s only day 2!

My current progress
I followed the advice given and went through some similar problems people have had.
I’m having a much better experience and there is more room for improvement as I go along.

I ran the flow rate calibration first and came out with these much better quality tests.

I then ran the pressure flow test on Orca and although not perfect I fiddled with it and got a better standard of print. I’m still having some problems with bed adhesion but it’s not been too much of a problem yet.

Then I decided to test the other calibration and was really pleased with the tuning on this. Everything fit perfectly first try.

I then printed a random shape and it came out really well. The only issue I’m having is the overhang as shown here is a little messy but it could have been from the supports I used.

So far I’m learning from my mistakes and really looking forward to future prints

Hello Theeym, this is never Bambu Basic PLA White, it looks completely different, is it perhaps Bambu Silk PLA? If so, then you need to choose the right filament in Bambu Studio. The maximum volumetric speed is approximately half that of Basic PLA.

Ah, that explains it then. I swapped to play matte and have gotten better results.

I printed this a moment ago with zero supports and am pretty happy with the overall quality.

Thanks for the feedback
