I’ve encountered an issue with a lot of unnecessary travel when slicing a thin structure for an aesthetic element—a single wall thickness where I’ve placed two angled sections on the back of the model to keep everything from not falling over while printing. However, I’m struggling to get the printer to continue the layer seamlessly above. Instead, it travels to the other side and resumes (see travel lines in the image).
I tried tweaking various settings, but I can’t get it to work.
I’ve considered vase mode, but then I’d have to waste material on a wall that goes back and forth behind the main wall.
The model has a 0.4mm wall thickness set with Arachne. I’d prefer to stay with the Bambulab slicer, as I have an A1 Mini.
Any tips on how to get this printed without all the travel moves?
There is no simple answer but have you tried to change the orientation of the model on the build plate to see what influences the nozzle movement algorithm?
The other question here is; what is the object or goal for trying to manage the nozzle movement? Perhaps if that were clearly communicated some of the community members may have alternate ideas to achieve the objective.
Have you tried either of these settings? It may not be what you’re looking for but both of them have an influence on nozzle path movement.
Thanks for the quick reply.
Tried Avoid crossing walls and that just made it travel inside the wall as expected.
I can’t find “Reverse on even” when searching for it
The idea is to make embossed flat art where I want to print quick, with little material, and get the aesthetic of vase-style prints. As such I wanna make designs that have low overhangs and only print 1 line per layer with 0.8mm nozzle. As such it would make sense for the nozzle to the XY-position while switching layer and then doing the next layer.
One option would be to print 3 models together as a triangle so it can run full vase mode, but I would want to achieve this for 1 model only.
Any other ideas on how to solve this?
I used Arachne now also given I have issues with Classic because it adds small extra sections (see image).
I know it might help to design the model so it has the same thickness everywhere in XY-space, but that is a bit tricky (for example, using Shell in Fusion 360 adds the thickness to the normal of the surface). Could one for example use a surface instead of a solid body to achieve the thin print?
Here is the 3mf if someone want to have a look. Would be much appreciated.
I would try Seam>Nearest. It seems like all the travel is to get back to the aligned seam (didn’t open the project, just guessing aligned, i’ll check it now).
Thanks. I tried Orca but does not work. It seems that “detect thin walls” and Arachne causes the issue. Doing classic without thin walls works. But it still makes a little loop when changing layers. Anyone know how to remove that?
Also there, there is a bigger issue at play here - not having perfectly uniform model thickness causes the printer to go back and fix small areas (see image).
Is there a way to remove those small parts with settings?
Otherwise I think I need to get the model into a uniform xy-thickness in Fusion 360, but I have not found such a solution yet - especially for more complex shapes. But any tips on how to model more complex shapes to get uniform xy-thickness would be great. thanks
For now I will just use vase mode and print two models back to back
