I have been working on a Macintosh case print (62.5% scale) and have been doing some test prints of small sections. These test prints are to check fit and finish issues. Last one I did have variable layer height turn on to improve surface finish on the top of the case. It also had magnets inserted to hold a fan hub in place.
Both those issues worked well but with the variable layer height Bambu studio put in a lot more supports and I can’t get them out. They won’t brake off of the attached top surfaces like they have in previous test prints. Even tried a heat gun and the supports got soft but won’t release from the top surface’s underside, it even pulled the print’s top surface down, see the picture.
I assume that is 0.08mm layer height? 0.8mm would be rather… large. With a lot of thermal energy fusing things together.
0.08 is a different story where a sufficient gap should help. But if you want to get a smooth surface which is easily removed, look at this thread: Support Filament --> PETG for PLA and PLA for PETG and more
Important key points: Use PETG as a support interface for PLA and vice versa, set support distances to 0.0mm and use a concentric interface pattern. If you have an “island” you need to get a bit inventive, but that box should work nicely.
I am a CAD user and have always been irritated by Bambu studio not having a orthographic orientation tool like Inventor where I can look at the Right Left Front Back Top Bottom plan view… Is there such a tool that I just haven’t found. Image above is just lining up as best I can to look straight into the view.
And yes, my bad on the typing it is a 0.08mm layer height.
may want to increase the spacing as well, or paint them on yourself, It doesn’t need to be full of support, just to keep from sagging.
You’d be surprised how far you can bridge.
The two circled in BLUE are where the magnet are going and it is putting supports there. I have a PAUSE in the slice so I can drop the magnets in, but I have to pull out those supports to get the magents in.
I can’t figure out a way to “Paint No Supports” there since I can physically see that surface in the “Prepare” screen, it is hidden since the magnet void is covered over.
Maybe I am not understanding your suggestion, but I don’t think it will work.
Plus now I am noticing this “Support Interface” (dark green) stuff seems to be what I am not being able to get off the “keep” material. Maybe there is a slicer adjustment needed for that…
Is there any chance it is a filament issue? The blue filament I used in the picture above was somewhat “wet”. My desiccant got over used, Bambu said it was 5 on the scale.
Here is a picture of the same model (but the full model as opposed to a small section) the supports there came off super easy.
Way too much. This indicates an urgent need to dry you filament and replace/renew all desiccant in the AMS.
So there should be the floor of the magnet cavity above it (i.e. 1-2 layers up). You can put a support blocker on that surface as @johnfcooley suggested. If not, there’s a misunderstanding.
Okay, I am definitely misunderstanding something then. I can not see the surface that needs the support blocker drawn on it in the Prepare state. It can be seen once it is sliced.
I will open up the Inventor model and show a section view here in a bit.
Okay, I am still missing something with the support blockers. Here is a screen shot of the painted Support Blockers, outlined in Blue. The 2 small circles in the area mark the magnet recesses
How do you get the Support Blocker marking to “travel through the walls into all surfaces you mark”… if that makes sense…
In this case I would want the support blockers to travel UP through the marked wall the distance of the horizontal wall itself. Is there such a setting?
