Hello :slight_smile: I’m pretty new to the hobby, got my X2D about a week ago and I’m overall very happy with the results; However I cant get the underside of prints to not be a horrible mess unless I print them directly on the buildplate. I’m trying to print miniature sized stuff mainly and the …

[image] user_3179428309: Is there anything obvious I’m missing? Nope. You are just diving in at the deep end. You’ll want to make sure that your filament is really dry. I.e. dry it yourself as new filament has frequently picked up moisture during its voyage across the seven seas. Next, for …

I’ve dried my PLA and by “Support for PLA” filaments as per guide in my AMS HT’s, they’re currently sitting at 30% moisture as per AMS HT display. What confuses me is that even after the prescribed 12h 50°C is wasnt much lower than it is now. I’m pausing on using the Support for PLA stuff right no…

There’s lot’s of stuff to learn with FDM :heart: :wink: [image] user_3179428309: I’ve dried my PLA and by “Support for PLA” filaments as per guide in my AMS HT’s This should have covered the basics. But I have used “Support for PLA” myself exactly once before switching to dissimilar support …

The different support generation strategies might reroll to a nicer base. In general some of those don’t generate “support interfaces” they instead rest on the tip of the tree, and I find those ONLY good at edges, if the big supported area is on those tips it tends to turn into a mess. If you can …

Currently I’m mostly using the slender tree supports with good success; But it’s not the actual support interfaces that are the issue for me but rather the whole underside of the print, even in the places where it does not connect to the interfaces at all. But I will try you suggestion as well, th…

To get the most possible quality with interface material in theory, you need to have 0 space, 100% fill for the interface lines and 3-4 layers for the interface. So the main layer will sit on completely flat area. Bambu Studio is notorious for delay over the latest algorithms with overhangs, which a…

Could you elaborate on what settings to change to get the full interface as you describe? And wouldnt that interface be terribly hard to remove?

The moment you change to different interface material in the support section ( as by default is the same material ) you will get one pop up dialog window asking you if you like to have the optimized settings and show you a list with like 10 things it will change. Then you can go add some more. I nee…

Yeah that dialog I am familiar with (although I have made little if any changes to the settings that are present after that) - interestingly when I print anything after that dialog, even the normal filament prints horribly (I end up with more or less instant failures due to super bad layer adhesion …

Are you increasing the purge volume or purge multiplier? I learned the hard way, failed 17hr print, using pla/petg that I needed to increase the purge volume. I use 2.5-3 for the multiplier now and a different color for the interface.

This is how I have the first layer / bottom layer / underside fixed for now:
