Two different finishes with same spool

If someone can explain to me why I have a different reflection level on the two pieces and why the top one has this texture, what settings I need to play with to make the result repeatable, please.
Thank you.

Printing Information:

Both pieces were printed with an X1C on AMS using Silk+ Purple Bamboo PLA filament and the default filament settings for bamboo PLA.

The top piece was printed with a 0.2 nozzle and the default bambu studio print settings “0.10mm Standard @BBL X1C 0.2 nozzle”

The bottom piece was printed with a 0.4 nozzle and the default bambu studio print settings “0.20mm Standard @BBL X1C”

Welcome to the community.

So that I may correctly understand, you’re saying that this is one model whereby you printed it, paused it, then changed the nozzle? Or is this two models side by side?

Either way, it sounds like your expectation is that a 0.2 nozzle and 0.4 nozzle will produce the same finish. That is exactly the opposite. The whole purpose of the different nozzle sizes is to trade off fine texture vs speed/Flow. They will never look identical nor should they. Think of it as if you printed something on a laser printer that was 200 dots per inch and you scaled it up to 2000 dots per inch. You’re dealing with an analogous affect here.

Also, as an aside, I can already see that your filament is not correctly calibrated and/or it has too much moisture, did you weigh it, dry it, then weigh it again to confirm moisture content or the absence of moisture?


If you’re relying on factory defaults - especially Bambu Silk or Bambu Matte - their factory settings are downright wrong, take it from my personal experience. You will want to perform a manual calibration, and not rely on auto calibration. For that, Orca Slicer is superior to Bambu Studio because of its baked-in calibration tools.

When you use Orca slicer, can it link and send project to the printer? Will it recognize the AMS? I thought Bambu disabled support for the Orca slicer earlier this year.

It depends on what revision of the firmware you’re using. The best thing to do is download it and try it out, it will only be a few minutes effort. Perhaps others here who have updated their firmware can comment. For me, I froze my firmware to pre-Bambu Connect precisely so I don’t have this problem and I also deleted Bambu Studio from my systems so that it doesn’t inadvertently try to overwrite the legacy Bambu Library that Orca uses.

OrcaSlicer does not support the dual nozzle H2D. I am not sure about using the new AMS 2 Pro or AMS HT.

OrcaSlicer works with A1, P1, X1 series Bambu printers and AMS, in cloud mode, if you have not updated to firmware requiring authorization.

OrcaSlicer works with A1, P1, X1 series Bambu printers and AMS with authorization firmware in LAN only mode, after selecting Developer mode on the printer.

You should also be able to export g-code from OrcaSlicer, then transfer the file via SDcard, or use Connect to authorize the file transfer via cloud.

Firmware requiring authorization:
A1 ≥ 01.05.00.00
P1 ≥ 01.08.02.00
X1 ≥ 01.08.05.00

Thank you. I will try it out.

I had similar quality issues with a model I downloaded.
In my case though it was the model geometry to blame.
This texture effect you have could be caused by the model just having straight sections where it should have a smooth arch.
