I also noticed this Divide by Zero issue with Organic Supports, specifically when I changed the "Overhang Threshold" value to 89 or 90.

i noticed this occur when a try my profiles, if a switch to any system profile this error not appear

• For Win, it shows this Error
• For Linux, it crashes immediately
• For MAC slices without problems

Should be fixed in 2.6.0-alpha4. Let us know if problems persist.

i just tested and same error persist, when i use my profile with organic suporte "PrusaSlicer has encountered a fatal error: "Divide by zero""

@Zannys can you provide us with your problematic .3mf?

[Zannys]

@kubispe1 this only happens when I use my profiles imported from 2.5, if I use standard profiles, organic supports works great.
The file with problems can be found here.

I also encountered divide by zero. it happened when I increased the overhang threshold to 90 degrees.
Settings:

• Version 2.6.0-alpha4+win64
• Windows 11
• organic support
• support on build plate only
• don't support bridges

[kubispe1]

We have detected some cases/parameters where divide by zero appears, but this specific issue should be fixed.
Also, a threshold of 90 degrees should be solved.
I am closing this issue.
