I’ve been printing LW-PLA Planes for a few years on a Prusa using OrcaSlicer. With a well design part I get an almost perfect outer skin. I just got a P1S and find that Bambu Studio is really close but it seems to have a couple of problems with Avoid Crossing Wall.
It seems that Bridges, Internal Solid Infill, and Gap Infill prevent the slicer from seeing a wall. I’m not sure if this is the correct terminology or conclusion but the print head crosses walls when these types of support are used. In the images below ignore the travel inside the part except for the pushrod tube support where there is a lot of travel because of the Gap Infill.
This first image is Orca Slicer. You’ll not see any external travel. I’ve walked through watching the head moves as Bridges, Solid Infill, and Gap Infill are printed and see that the head travels inside the object.
These next images show the support parts at the wall crossings. One fix for Bridges is to turn on Thick Bridges. I cannot see how to prevent wall crossing for Internal Solid Infill and Gap Infill.
The feature’s name states it all. It called “avoid crossing walls” not “Prevent crossing walls”. I’ve tried to get the slicer to obey this request and it is only marginal.
I noticed this a few times as well but am not too fuzzed about it.
It seems certain things affect how often or not the head moves in unexpected ways.
Like the order of the start points, nearest seems to create fewer hassles than for example random.
Then there is the parameter for avoid crossing walls…
The max detour length defines at what point the slicer might still cross walls.
Orca might adjust this value based on wall length or such but Studio only has the value you can adjust.
By default, if I am not mistaken Studio has a zero here.
If you adjust this value up enough you should get a similar result to Orca.
Yes, I’ve tried a few values in there and just tried 9999. I believe that’s the same as 0 which turns it off and always detours. The sliced results are exactly the same.
I believe 0 means never detour, but I have tried different values in there but the results are the same.
It seems that Bambu Studio no longer thinks it’s near a wall or the idea of a wall changes because of the support. Orca Slicer prints the bridge, or infill… whatever, and continues to move the head inside the part.
I know it’s just the way the same feature has been implemented differently.
Prusa Slicer is a mess with this feature. Orca Slicer got it right. Bambu Studio is almost there, but it Bridges and Infill mess it up.
I don’t mind using Orca Slicer, but I lose the camera view on my phone… so I have to physically keep checking on the print.
I’ll try the print with Bambu Studio since it is only a bit. Having the camera may override a few imperfections.
I slice and print with OrcaSlicer. Once I “Send” or “Print” the project, the slicer is not involved in the print. I can still use Handy to monitor the print, or Bambu Studio, or Orca, or a combination of those programs at the same time.
Orca slicer is a superset of Bambu Studio. It supports 99% of the same functionality while at the same time supplying 20% more quality of life features not incorporated into Bambu Studio. You have the freedom to operate it with or without LAN mode and operate it in place of Bambu Studio. The bottom line is you can run both Slicers on your machine at the same time with no downside.
You know… it really is simplest things in life that get you. I didn’t log in from Orca Slicer. I don’t know why except I thought I was logging into Orca… not Bambu.
I logged in and have… well… everything. Thank you.
“Advanced” settings should always be turned on. Even if you don’t need them, do not know what they mean, at least you can see that they are there, and the day will come when you say “That looks something that might help…”
