WIP: Port latest support code from BBS

[Noisyfox]

This includes the latest changes from BBS, including vertical support painting.

Huge PR, lots of tests are needed.

[Eldenroot]

Great! Paint brim feature and step import settings and I will be happy :)

Good job!

Is there any list of features which are not included from Bambu slicer? Just to know ....

Found some problems and difference on my test file. It has 4 object stacked with 0.4mm air, auto snug support with different material.

1. Filament changed on wrong layer.

2. Missing support layer.

3. Pattern angle have same direction.

Maybe more I haven't noticed yet? Here is my test file: Support Stack Test.zip

Issues #1 & #2 are solved by deleting the Delete Me Before Print-part. 😄

And issue #3 is resolved by choosing Rectlinear Interlaced as Interface pattern.

Yeah appearently in current Orca the support interface pattern Rectlinear and Rectlinear Interlaced are inversed somehow. And the namings are different from other places as well. They are called Aligned Rectlinear and Rectlinear respectively everywhere else. I'll try make them unified.

[rikaunite]

Wow thanks! I tested again and Rectlinear Interlaced fix all three issues.

Also the icons are not right in my opinion.

This was already addressed in #5565.
Maybe this could simplify the work a bit. 😊

If you need this little cylinder and don't want to delete it every time before printing:

Just right click it and untick Printable. 😊

[rikaunite]

@discip
Didn't find that, maybt it's only available for whole object?

I've mess around the code to make every stacked parts has a "first layer". This little cylinder prevent slicer throw "Access Violation" on me. I don't know why but it just works. 😄

Ah, you are right. In this case it only applies to the whole assembly. 🤦‍♂️
It's this green check mark:

downloaded the latest nightly ( so my apologies if thats not the same as this I'll re run tests accordingly if need be)

having issues with support generation not working as expected on numerous instances unfortunately all found stemming from a missing feature (sheath supports in prusa/ perimeter wall in tree for normal supports)

bottom support interface on hybrid supports ( lays down regular support walls first)

expected (roughly result) from prusa

if i use concentric pattern it doesn't do the random lines but does do a bit of extra on the outside of the print on the base filament (before the interface has been laid down so it wont be attaching to anything this happens completely sporadically. When going back and forth to take all the screenshots sometimes it didn't happen)

using snug gives a proper interface however has open areas at the end of the bridge to start the interface so that wont adhere proper

rotated pattern angle at 135 45 which makes the bridge go a proper direction where it wont completely hurt the print however theres an open back corner that will flop just like the "regular way" this would be fixed by having a) a perimeter or having concentric infill in addition to the other options (this would probably be the fastest printing method too as well)

hybrid with support blockers for the holes ( tried auto as well as manual neither one respects the support blockers) strong doesn't have this issue with going in the hole but takes considerably longer normal supports on grid spacing technically doesn't have that issue because it just draws an un needed line through it lol)

random little line that popped up that isn't supporting anything

interface not printing on first layer where unless 0 object distance (sporadic) switching between modes will clear this us .. usually clears up switching modes

honestly the results changes basically every time you switch back and forth between modes.. in getting these screenshots i had a range of 2h:49 for the print and 3h:45 and no settings were changed it was just whatever it did that time. the fact that it's not consistent intuitive is also frustrating

i love orca .. but the experience with supports is infuriating because 1 they're not consistent so you can't even try settings out and be able to go back to what you had before confidently if it did happen to be a "good" result I just tried 40* on strong tree supports and it was 3h:3X then i changed it to 60 in hopes of it not putting any interface on the bottom and not only did it still touch that part of the part print time went up to 3:4x realistically having the angle be able to be larger should mean it can not touch at all and not need to do a filament change basically every option available i could choose for supports

also for reference this is where my supports are painted and i tried both manual and auto ..

closed and re opened it again and got wildly different results including it' not respecting build plate only

@digital0785 the nightly only contains whats been merged so not these changes that are still awaiting merge, HOWEVER, the fact you did the testing with the nightly is great, because when you download this test build, you know what your looking for

I need to check floating supports on this build this weekend... time, never enough

ahh ok so i need to build this myself if i want to test or just waiting for the nightly with these ?.. the irony is i jumped to nightly 3 weeks ago because i ran into a bug in 2.2 where when i shut it down it would nix all my profiles .. 2.3 hasn't .. but the final model i printed of this was from 2.2 with only build plate because i got one that sliced where it would bridge the gaps properly and only took 3 hours vs the 3:30+ most of the screenshots show.. but yes I look forward to testing this.. I usually avoid needing supports but I have a project i need to print 10 of for a client and there is no choice but to use support :(

Someone posted this thread in response to a post I made on FB frustrated so at least I was pointing in the right direction :). I'll definitely be on the lookout as I'll be glad to help improve supports in any way i can with feedback. as they're the bane of my existence LOL

looks like it's in process to become a nightly?

thank you so much! downloading right now to play with!

i'm not saying i could cry i'm so happy .. but ... i could LOL

best way to shut up a disgruntled user i've ever seen LOL

[digital0785]

only issue i'm really running into at this moment which could be something i'm missing something depending on the interface pattern changes the direction the top layer of the support before the interface goes .. going 45* creates less that stellar results as it prints at support speeds and it tries to fill gaps in an un optimized way. rectilinear goes the shortest direction (if rotated 90* but tries to bridge the whole width of the support other wise) which makes sense however then the interface layers themselves are all going the same direction instead of alternating 90*. every other option minus regular rectilinear makes the top layer of supports at a 45 and changing the pattern angle doesn't change the top. if possible having it do shortest distance may be better or giving the option to manually adjust that angle :) or having the option to slow down that bridge layer would help / have it use the support interface speed or bridging speed vs standard support speed. I had gaps forming in that layer which caused the subsequent support interface layers to go down a bit weird and cause some scarring

thank you again for the updates!
