Or are you saying that I can’t use
and have to use “tree(manual)” and paint in all the supports I want just to avoid the small area that I can’t get too paint support blockers?
That would seem a rather inefficient programming choice for the Slicer program.
You’re correct, you get to choose auto or manual.
If manual, you gotta paint it up.
Check what the automatic support gen will do if you enable “On build plate only” support option. Also check how the supports generate when you use different styles. Organic and Hybrid tend to create very different tree branch paths and interfaces, one might work out much better depending on the model.
Bullocks,
Using “On build plate only” leaves a large section unsupported, see below (the dark blue area):
Plus when I go to the full model (this is just a small section to test / resolve other issues, it will be enclosed on 3 of 4 sides so the area from the build plate only will be insignificant, I am thinking, to get all the areas supported, like seen above.
Where do I find / set “Organic and Hybrid”?
it’s not in Type and I don’t see it else where.
Re: Hybrid, Organic, etc:: One setting down from Type: “Style”. There are different styles for both tree and normal.
Re: Not on build plate:: I see. You might be able to influence those areas to be reached by increasing the Tree Support Branch Angle. (greater angle allows it to reach farther inwards and snake around more gracefully from the edge of the plate) It defaults to 45, but I’ve found that angles up to 65 still can work well, especially if the material you are using is dialed in for overhangs to begin with. But if your whole model is boxed in, then I dunno, you might be stuck with putting them on the model.
When painting the blockers, try using the sphere tool instead of the circle. The sphere will block supports within a volume. The circle only blocks supports on a surface.
Style - Sneaky…
“Seek and ye shall find, knock and it shall be opened unto you” as opposed to the “Ask, and it shall be given you” that I did…
Much appreciated Bullocks.
Ikraus,
Nope, that doesn’t carry the Support Blockers through to the hidden surface above or below the “support blocker MARKED area”. I set the Pen size at 8 (as large as possible) and painted “blockers” on both the top and bottom side of the magnet recesses and and it still put supports in the magnet recesses.
FYI, the distance between the “Top” and “Bottom” surfaces is 6.25mm, so if 8 in the setting means 8mm it should be penetrating the entire wall.
Use the “Section view” to access the hidden surface. You have to paint the actual surface the support is generating for to disable it, not the surfaces around it.
Can you upload the .3mf file you are working with as it will be easier to show how to correctly generate support for it.
JonRaymond,
I thought “Yea Hoo” that’s it!!! But nope… Unless I am not doing it correctly.
It is hard to show, but I painted the entire surface of the magnet recess
But it still puts support there.
block support under where it would be
Support from build plate only.
My head hurts. Send me that file and I’ll slice it.
Just to double check you are painting the overhang area with support blocker? Painting the floor of the cavity will not stop support from generating.
As I already requested, please upload the .3mf file so we can solve this.
JohnF and Jon,
I wasn’t painting the correct surface, but I am now…
No supports are in the magnet recesses.
Thanks SOOOOOO MUCH for dealing with my slow mind.
Now I just have to get the filament out of the drier, place into the 10% humidity AMS with fresh desiccant and print again and see if the support come off.
And yes the horse is FINALLY dead.
In case somebody gets here in the future concerned about Variable Layer Height and Not being able to get the supports off, like they are firmly attached to the model and will not break loose
I have so far determined that YES, Varible Layer Height does (for some reason) make the supports very difficult or impossible to remove. I printed the same model with both Variable Layer Height (at 0.08mm) which is FULLY bonded to the model as shown above. However with 0.2mm layer height the supports broke off relatively easy.
As you might have seen in the thread, the blue PLA filament used in the picture was rather “wet” and this may have contributed to the support to part adhesion problem. I dried the filament out (12 hrs in a filament drier) and with Variable Layer Height still used it was slightly easier to remove the supports, but still not possible in many areas
Once I sliced with 0.2mm layer height the supports removed almost completely, but still a little difficult to break off at points.
I think the moisture content of the filament might still be contributing to the adheasion of the supports to the part problem, but the main driving issue is the Variable Layer Height.
Unfortunately I really need Variable Layer Height to get a sloped surface on the part to look like something other than ■■■■-o-la…
Is there a reason you can’t print this part with this face on the bed? It would get rid of most of your support issues.
