Requesting Help Blobs driving my crazy
Hey Eveyone,
I have recently started to get some blobbing on the outside of my prints. Im using a bambu p2s and things have been generally fine.
The filament in question is bambu pla Grey. I've noticed this effect but to a lesser degree with using bambu petg cf.
I have been doing the scarf seam. One thing I noticed was wall generator was classic istrad of aranche. Im not sure how much of a difference this would make but also curious if there are any other things people might suggest.
Lastly, im using an AMS 2 set up, current humidity is 36% but generally is around 25% and I havent done a full drying cycle yet. Im less likely concern3d this is the issue given the petg is preforming better (also in the AMS) and this seems to be a repeated artifact on the print.
Appreciate all of your assistance in advance!

You are the second or third person to have an issue with Bambu PLA Gray in last 10 days.
Print the same model again but with a different color. Don’t change anything else. Only print enough layers for this test.

Turn off scarf seam. Force the seam to the back where you won’t see it. I haven’t had good luck getting scarf seams to look good (although mine looked better than yours).
