Slicing with non-planar and perimeters about slic3r HOT 15 CLOSED

key.txt

Can't upload a .stl so I've renamed to txt - rename back to .stl to use

from slic3r.

You need top solid layers because these are the layers that get projected as nonplanar.

from slic3r.

Ah right.. I'll set top layers back to non zero and update with the result.

@Zip-o-mat I'm not super familiar with Git. Can you advise which branch is the latest? Assuming master but confused by master_merge

from slic3r.

The latest branch is the nonplanar branch

git checkout nonplanar

I have just seen that the readme was still showing the old master_merge branch. It is now correctly referencing the nonplanar branch.

from slic3r.

Cool. I think I used master_merge so I'll recompile nonplanar for this next test too 👍

sorry for the linux/perl noob question. I get the following error after trying to run perl slic3r.pl
I didn't get this on my last build... (admittedly using a different linux distro)

An easy fix?

Can't locate Slic3r/XS.pm in @inc (you may need to install the Slic3r::XS module) (@inc contains: /home/xubuntu/Slic3r/local-lib/lib/perl5/5.30.0/x86_64-linux-gnu-thread-multi /home/xubuntu/Slic3r/local-lib/lib/perl5/5.30.0 /home/xubuntu/Slic3r/local-lib/lib/perl5/x86_64-linux-gnu-thread-multi /home/xubuntu/Slic3r/local-lib/lib/perl5 /home/xubuntu/Slic3r/lib /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.30.0 /usr/local/share/perl/5.30.0 /usr/lib/x86_64-linux-gnu/perl5/5.30 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.30 /usr/share/perl/5.30 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /home/xubuntu/Slic3r/lib/Slic3r.pm line 53.

So I redid the build and this time it works.... not sure what went wrong the first time as it seemed to complete the first time. All good

Ok so I have retested the latest non-planar branch. It seemed that the hollow model with recessed text may have been causing extra complexity in the *slicing (edit) so I simplified the example by using TeachingTech sample model. Here is the output

As you can see, it has done something weird with the top layer and projected a solid square on top of the non-planar contour.

It may be a bug somewhere because if I then disable non-planar, then re-enable non-planar again, I get the following which looks more like what I'm after

I suspect it's something in the order of the settings selected that is causing this bug. I had the same issue turning on and off 'thin wall detection'

If need be I can record a video reproducing the steps, but hopefully you can reproduce

from slic3r.

PS I saw this same behavior in the previous master_merge branch when I first built it. This is why set perimeters to 0 which led to the first 'stepped' example I initially reported

from slic3r.

The STL file I used in the second example

from slic3r.

yeah this is a known bug.
The projection is not done correctly sometimes.
The workaround is to disable and enable nonplanar as you did.

Thanks for your time. Happy to merge with the existing issue and close, or keep open till the bug is resolved....
