^ This is the model created in the slicer with just the support interfaces visible, note how support interfaces are only generated for the top.
^ And when we look at the cross section we see the printer makes the support out of the same filament as the object filament, and places this support directly on top of the object.
I am attempting to get the first 1-2 loops of the tree support that are created on top of the object to be made of support filament (not the entire support itself) so that it doesn’t bind and scuff up the surface of the object. I have tried a bunch of settings in the Support tab and none seem to make the slicer create a bottom interface layer.
To further reiterate or clarify the issue if I have been bad a communicating it:
It seems to be an issue with “Tree (auto)” as “Default (auto)” support type does generate bottom supports. I would like to try and get “Tree (auto)” to generate this bottom support so I will keep the post up.
Has this been resolved? My [Tree Auto] supports are super weak when printed ON model due to a complete lack of interface. They break off 100% of the time within about an inch of height at Silent speed with support speed chopped down to 20mm/s w/ a 1mm retract z-hop. Even with the gentlest settings, just an application of layers will eventually break the support from the model (a perfectly flat surface on the bottom).
This of course does not happen with Normal supports, you can SEE the interface there in the slicer. But nope, not with Tree whatsoever. I can get those in to Cura all day, and they’ll stick like glue, but Bambu Lab simply refuses to input a lower interface, so I’ve burned through probably 2kg of filament throwing away the first 1.5 inches of a friend’s dice tower. I’m giving up on tree supports and just going with Normal (even though I can see where they will clearly print “in thin air” in several places due to the complexity of the model).
Maybe it’ll work this time without any spaghetti monsters. Eighth time’s the charm.
And yes, the printer is correctly tuned, the nozzle is straight, the lines are perfect otherwise, the temperature has been tested from 215 - 225, slow speed, normal speed, aux fan on, aux fan off, gyroid fill, avoid walls… All of it. Sometimes they’ll break at 2 inches. Sometimes at 1 inch. Sometimes it’ll be the left, sometimes the right, sometimes the center. It really is just completely random - but it always breaks at the very bottom from simply being overly "touched’ and there being nothing but 2 wall loops to glue it to the model surface. I’d probably have better luck just pausing it after a few layers and filling the bottoms with super glue or molten filament, letting it dry and then resuming print, since clearly the slicer has zero capacity for generating a functional support-tree on-model lower-interface.
I’ve never used OrcaSlicer. I like how the interface is very similar to Bambu Studio, but how well does it jive with the printer? I’ve read mixed reviews seen a lot of forums where the issues I don’t have were fixed by returning to Bambu from Orca.
Is there any way to throw a rock at the devs to draw their attention to this hidden gem?
I’ve never had a problem using OrcaSlicer with my X1C. Bambu Studio (particularly the new v1.10) has a few features that Orca does not, but I still feel OrcaSlicer offers better overall control. I think to some extent Bambu intentionally limits Studio so that new users are not overwhelmed with all the possible settings. The Studio developers are well aware of OrcaSlicer and have credited Softfever/OrcaSlicer for many Orca features now in Studio.
The nice thing is that your slicer choice is not either/or… You can install both, and syncing through the Bambu cloud, your User printer/filament/process presets can be used by both programs.
OrcaSlicer can open a .3mf project file from Studio/Makerworld; Studio will only import geometry from an OrcaSlicer .3mf. Studio requires the project be uploaded to MW to edit the Project tab info; OrcaSlicer lets you fill out the tab on your computer for your personal use.
Well dang, lol, youve just sold me.
Can OrcaSlicer slice for Ender printers as well? If so they’re gonna have a new follower!
I can understand the sentiment about not overwhelming new folks with settings. I’m by no means new at this at this point (too many fails, successes, and more fails, to feel new anymore) so I thought the simple fire-and-forget effectiveness of Bambu Studio was rather a breath of fresh air until I started attempting to print non-geometrical things on it and noticed it has a funny habit of printing in thin air sometimes where Cura knew exactly what it was doing.
But, I can add negatives on the fly in Bambu and that was something Cura simply cant do right now.
So yeah. I’ll absolutely look into it now!!
I’m still avoiding Klipper tho on the Enders until somebody tells me why I SHOULD move from marlin
Roflmao. Hmm.
Sounds like a slim chance.
They are Ender 3 Pro’s. Quite rare and novel I hear. I had to drive, like, an entire 5 minutes away to buy my second one off Facebook Marketplace
It would be nice to have a single slicer, and maybe a bit more intuitive control than Cura. The ability to poke holes in things and paint supports where I want immediately knocked the wind out of Cura for me.
Though I do love how buttery smooth my prints come out on the low and slow Enders. Especially the non-geometric ones that require lower interfaces for on model tree supports
I would not say it is resolved. You’ve found a workaround for a specific scenario.
I tested what you proposed, and initially it did not work. If I have “Bottom interface layers” set to “Same as top” (while having “Top interface layers” set to for example 2), it will also not generate any bottom interface. But if I set “Bottom interface layers” to 1, 2 or 3 then it will.
@BambuLab halp! We cant get our trees to root properly!
I’m a little disenchanted that this is an issue in BambuStudio but never posed a problem in Cura.
Ive always used Cura, so when I dove into Bambu and experienced the difference, I was stunned (like so many).
But here we are dealing with a strange quirk that had nothing to do with the printer and everything to do with the slicer o.O
A print which would take a week on an Ender 3 can be done in 20 hours on the Bambu… except it cant actually be done at all because of some relatively basic functionality like having a support be able to stay where it is supposed to be rather than just being set down on the print model and hope for the best. Thats a 100% fail rate scenario. I cannot think of an application where zero bottom interface on model would be useful whatsoever - not even in a minimum layer support scenario (say, only a <1 mm gap between flat vertical layers) where the interface itself would serve as the support and could/would be fished out like a wafer.
I suppose in that scenario Maybe the “top” interface would come into play… but what about situations where the distance goes beyond the thickness of the top interface… I get that the slicer would just print a multitude of tiny trees, but, again, it could simply print minimum interface layers instead and the “support” would come out like a crispy waffle.
The scenario I’m talking about is actually something Ive experienced already in my short time with 3D printing.
I was printing a big dice tower for my DMs wife and her choice of tower had about a 1mm gap between a balcony, which extended about an inch out from the main wall, and a little mini side tower thing which came out horizontally over the balcony and then angle upward.
The mini tower and the balcony were not connected, but rather separated by only a few “layers” of air space.
I didn’t catch that detail until after it had already printed and I was cleaning off the supports and realized “oh no, what kind of mess is going on in this microscopic air space between these two things?”
But when I poked my tweezers in there to feel around, out popped a little waffle waver of filament only 2 layers thick, the size of a quarter, pretty as you please. There were zero imperfections between the two close-proximity surfaces, and the removal of that bit of support interface was laughably easy.
I am having a similar issue. I have a flat plate with a box modifier and the box is not being supported. I am new and have a feeling i am making a mistake somewhere. I cannot upload a picture which would help describing the problem.
seen a lot of forums where the issues I don’t have were fixed by returning to Bambu from Orca.
