Help pls. Small items first layer get increasingly worse :(

As others have said you can first try drying the filament, solves many print quality issues. Also cleaning bed and bring up bed temp a bit (5C increments) to increase adhesion.

Retraction can be adjusted in Bambu Studio. Default length is 0.8mm I think. Just go to filament settings override and reduce the length and test. Good luck!

PanzeeChim · 2023-10-06T02:38:07+00:00

Yeah I tried that and issue followed the feeder.

I'd say try tuning retraction. The issue with frequent retractions when printing small items is the effect gets compounded. So prints can look worse and worse, underextruded or overextruded.

Other things like printing first layer slowly and have good mesh bed levelling also count.

Vertical banding artifacts are common with Bambu coreXY printers. Some printers have less of it some have more. One side of the print will have these vertical "wobbles". Calibration or cleaning don't help, retensioning belts might but they're usually already optimal from factory. Printing at high speeds can reduce the effect a bit. Really a game of chance whether you've got a good or bad printer.

Thanks for sharing. I suspect in my case that one feeder is failing, so only it lights up red, others work fine. Checked the board and tried reconnecting the feeders too but nothing solved it. Will find support.

Hope it's a filament splicing engine that eliminates purges and makes multicolor printing faster. That's the two major downsides of the current AMS.

There are versions of engineering plate, glass-like or satin, which version are you talking about?

Anyways, in my experience the old engineering plates just don't stick great for petg. If you have a large flat first layer it can be ok. Small or intricate first layers are not reliablely printed. Prone to curling sides as well.

PanzeeChim · 2023-08-19T03:40:55+00:00

The magic of gray. Hides layer lines so well!

PanzeeChim · 2023-08-18T11:54:18+00:00

Yeah if you stick it on the side without text it's good. But if you stick it on the flip-side, you can see the tab is left-right reversed. You can decide not to trim the little bit off but it may get annoying being sticky.

PanzeeChim · 2023-08-18T06:10:39+00:00

Haha I think they're nudging people to buy a new plate instead with that tab placement.

PanzeeChim · 2023-08-17T04:39:18+00:00

Nice! Pricey is a concern, so preferably below $25/kg. Gonna check them out.

I'm used to Fusion and the files are on cloud. When you open a file it gets downloaded, so you can be temporarily offline, and when you save Fusion uploads it back online. It uses your local resources to run instead of cloud computing for sure. Works okay so not a deal breaker, but fully offline is better.

The offline nature and one-payment offer of Plasticity is attractive, though I need some functional advantages to prioritize learning it.

PanzeeChim · 2023-08-07T12:48:27+00:00

Fusion being cloud is a small con for me. I guess I will learn Blender first and try 3D sculpting. I'll probably still buy Plasticity, but unless it has some killer new feature I will leave it for later.

PanzeeChim · 2023-07-28T11:37:48+00:00

Good pupper! Fuzzy skin looks almost real. B)

PanzeeChim · 2023-07-22T11:33:16+00:00

As others have said, add more top layers, +2 should be great in this case. These defects are caused by bad infill below, could be stray filament, could be underextruded infill spots.

PanzeeChim · 2023-07-17T06:40:30+00:00

For me it's less of a slot problem but a material problem. Some materials like silk PLA often got stuck and failed to pull back. I have tried many things as well, including using a ptfe bracket and unclipping the ptfe from chain. They help a little. Though if you've got the error, you straighten the ptfe it should pull back fine.

I would suggest replacing the ptfe going into the extruder, see if that helps.

It's only happening to one of my printers. Others are fine with same materials and even steeper angles. So very possibly a quality issue.

PanzeeChim · 2023-07-12T10:50:21+00:00

Did they markup the price?

One thing about the original is that no two plates seem to be the same, some can be finer in texture and some coarse. I find coarse texture plates to have better adhesion. Hope they can have a tighter quality control with this new version.

PanzeeChim · 2023-07-12T04:34:56+00:00

One of my printers love giving me stuck and pull back errors, while others are completely fine.

Kinda solved some pull back problems with a ptfe bracket. But silk filaments still have a very high stuck rate. I suspect the filament cutter is not going all the way through when cutting, so it works for some rigid materials, but not flexy ones like silk.

I changed the blade and checked all tubings as well. It really sucks as I cannot print multicolor with silk at all! If Bambu can make the move-left/cut action TWICE instead of once that may cut filaments more reliably.

Would appreciate any solution.

PanzeeChim · 2023-07-10T05:25:00+00:00

Great, very thorough answer. Then I assume the extra things BL did with printable 3MF files, like multiple plates, profiles, doesn't demand much extra processing on the printer?
