PrusaSlicer-2.3.0-alpha4 crashes during slicing

jaapp commented 3 years ago

Version

PrusaSlicer PrusaSlicer-2.3.0-alpha4+-202011211604

Operating system type + version

MaxOS Mojave 10.14.6 (18G4032)

3D printer brand / version + firmware version (if known)

Prusa MK3 MMu2S stock

Behavior

Start Prusaslicer from .dmg image
Create default Prusa MK3S MMU2S profile
Update all filament profiles
Drag model into buildplate
Use Place on Face function to reorient model (this is important, in other orientations the error does not occur)
Slice model
Crash

This orientation slices fine:

This orientation causes a crash during slicing.

Is this a new feature request? No

Project File (.3MF) where problem occurs

Unfortunately this is a paid model. The license doesn't allow me to share the file.

I am having the exact same issue. Try to slice an mmu model and the slicer crashes.

drelich commented 3 years ago

I don't even have to slice an mmu model. Simple one colour Deadpool bust crashes PrusaSlicer mid slicing... Looks like I'm going back to Alpha3.

I have the same issue on Windows. It doesn't happen with every model though. When I add a particular modem to the build plate, no matter how muich more is on there, the slicing crashes. I can share the STL's of needed, but they are part of a paid model (Steering Wheel A.stl and Steering Wheel B.stl) from the 3DSets Mode 6 Rancher 4x4 Wagon v1.0.2.

Same here, alpha4 crashes on several simple parts when layer heigh equal or greater then 0.1mm, with or without multimaterial. crashing_2.3.0_alpha4.zip

Yup...crashing when trying to slice even simple files. Here is the offending file for me. Printing a Minecraft figure for my grandson, and this is the helmet he can wear. I'll attach the project file.
Minecraft_Steve-Helmet.zip

Dealing with the similar issue plus a odd issue. First if I hit " command + "I" on my keyboard it doesn't open up the import stl window like in previous versions it just opens up a whole new prusaslicer app like opening up a new window in your browser. Then it crashes when I click on slice now. I'm hoping this is an easy fix for them because I was looking forward to all the new features. Till then I'll keep using Alpha3.

Likely a duplicate of https://github.com/prusa3d/PrusaSlicer/issues/5208

I can confirm that trying to slice the Minecraft_Steve-Helmet.zip file shared by @Gacky2k also crashes PrusaSlicer during slicing

It only crashes if I import your entire 3mf. If I delete the config files (inside 3mf) then it works. So, my guess is, that your config does something funny.

Delete *.config in Minecraft_Steve-Helmet.3mf\Metadata\.

I got it to crash using the default profiles as wel. To double check I also extracted the STL from the 3MF and made a new project trying to slice the STL. Also resulted in a crash.

same here on debian using the tarball - 2.3.0a4 segfaults so much more than a3 and 2.2.0 never crashed once. no MMU, 0.1 or 0.2 layer height and any infill type.

it seems to be to do with scaling. if i load marvin and just click slice with my default settings it works fine.

if i scale it any larger than 117% it segfaults and i get this from gdb:

sometimes i get this error too:

[2020-11-23 12:54:51.636211] [0x00007fffeeffd700] [error]   GCodeProcessor encountered an invalid toolchange, maybe from a custom gcode.

i originally thought it was to do with changing infill type to some of the newer ones, but it seems to crash even with rect/honey. could be 2 issues i guess. it's also a lot slower to slice than 2.2.0 - the statistics seems to be the culprit not the actual slicing.

its not 100% reproducible, sometimes it works fine but most of the time it crashes when scaling.
