Bug 251236

Summary: cad/cura bug in 4.7 causes slowdowns in circular perimeters; fixed in 4.8
Product: Ports & Packages Reporter: Sebastian <sko>

Description Sebastian 2020-11-18 11:01:02 UTC 
In Cura version 4.7 a bug regarding slowdowns in circular perimeters was introduced (or at list gets triggered much more easily than in earlier versions):
https://github.com/Ultimaker/Cura/issues/8321

This issue makes v4.7.x hardly usable.
Sticking to v4.5 has become quite "tricky" to say the least, due to the massive python-induced dependency hell and lots of dependencies being too new and/or incompatible for the 4.5 version.

Version 4.8 has been released on November 10 that fixes this glitch in the simplification algorithm. The issue is still open, but is considered to be solved with 4.8 and changed default settings for Maximum resolution and Maximum Deviation.

From the Changelog of 4.8:
Fixed under-simplification (blobs, zits) on some printer models. An oversight in 4.6.x resulted in an oversimplification (smoothing) of models. The attempted fix in 4.7.x overcompensated, which gave difficulty (zits, blobs) for some printer models when the resulting gcode became too intricate. This is now fixed, though some profiles might need to be updated, since they where made against 4.6.x, and therefore may rely on the over-simplification.


Would it be possible to fast-forward to 4.8?

Comment 2 Tomoyuki Sakurai 2020-12-24 05:29:21 UTC 
the port uses USE_GITHUB=yes, yet the commit did not change GH_TAGNAME. the package is still 4.7. as a proof, SHA256 in distinfo is identical. confusingly, the version in "About" says "master", not 4.8 nor 4.7. this PR should be reopened.

Oops. Ok I goofed. I'll look at this today.
Comment 4 Tomoyuki Sakurai 2020-12-25 03:35:51 UTC 
here is new dependencies for cura 4.8.0.

Comment 5 Tomoyuki Sakurai 2020-12-25 21:24:50 UTC 
with my WIP ports, poudriere bulk succeeded. i'm using cure 4.8.0, and it looks fine.

  Apparently I forgot to remove a line causing the wrong cura version
  to be claimed as an update to 4.8
  I think I have it right this time. Apologies I should have noticed.
  I'll take the pointyhat and go sit in the corner.

Comment 7 Tomoyuki Sakurai 2020-12-28 04:21:54 UTC 
cura is just a front-end, and heavily depends on its dependencies. without updating depended libraries, new version will not provide what the release note says. this is especially true in this PR, as the reporter needs fixes in cura engine, the slicer. I'm sure that new package will not even launch as cura needs new run-time library that I mentioned previously. please have a close look at my repository, and test the application before committing.

Comment 17 Tomasz "CeDeROM" CEDRO 2021-01-27 16:21:09 UTC 
I can confirm that Cura-4.8.0_4,2 is available from pkg and it works for me.. the last version crashed on start.. this one starts displays objects etc :-)
Comment 18 Torfinn Ingolfsen 2021-01-27 22:29:53 UTC 
Confirmed here as well (installed from ports:
tingo@kg-core1$ pkg info Cura*
Cura-4.8.0_4,2
CuraEngine-4.8_1,1

when cura exits, it leaves a Python core file behind (not important, but still)
tingo@kg-core1$ file python3.7.core
python3.7.core: ELF 64-bit LSB core file, x86-64, version 1 (FreeBSD), FreeBSD-style, from '/usr/local/bin/python3.7 /usr/local/bin/cura', pid=34115
Comment 19 Tomasz "CeDeROM" CEDRO 2021-01-27 22:50:51 UTC 
True. I have sysctl kern.coredump=0 so no core dumps, but log shows some issues noted below. Not sure if this is dependency or the application problem though. Probably would be good to see this application version on another platform to compare.. or similar application on FreeBSD?

zsh: abort      cura
Comment 20 Tomasz "CeDeROM" CEDRO 2021-01-27 22:58:42 UTC 
This may be the upstream application problem as several similar issues were reported already on project github issue tracker:

https://github.com/Ultimaker/Cura/issues?q=is%3Aissue+is%3Aopen+crash+exit

Did that happen with previous versions of cura here?
Comment 21 Torfinn Ingolfsen 2021-01-28 11:06:35 UTC 
Data point:
I download and tested the Cura 4.8.0 appimage on a Debian laptop, it did not crash on exit. As for previous version on FreeBSD - I don't knw if they crashed or not. I have no logs or notes about it.

Just to add to the mix here (I can open a new ticket if you prefer):

Missing dependency: py37-qt5-svg (Icons render as black squares without it.)
