Behavior

• The Prusa Slicer is generating a badly looking Gcode, some layers are missing or are badly generated.
• When using the Cura slicer Version 4.8.0, no problem occurs and the Gcode looks fine.

Project File (.3MF) where problem occurs

(impossible to join files with an .3MF ???? , got a "We don't support that file type" message from GitHUB) ==> So you will have to remove the .TXT at the end of the following file to obtain the .3MF file Bod 3.3MF.TXT

The STL file used : (again, impossible to join files with a .stl extension ???? , got a "We don't support that file type" message from GitHUB) so, remove the .TXT extension a the end of the following file Bod 3.stl.TXT

Cura 4.8 gcode generation picture for the stl file :

That stl has the following errors - Non manifold edges - 14 (these will be the biggest problem for PS) Intersecting Faces - 22 Zero faces - 1007 Thin Faces - 37 Sharp Edges - 22

Report generated with Blenders 3dprint tool.

Here is a fixed version of your stl using the same tools Make manifold button. Which I quickly sliced in PS2.3 and it looks ok to me but its not my model so I would check it fully. It doesn't have the huge missing bits that the non manifold errros cause though.

Hello, yes I saw that the STL generated by Fusion360 was having errors in it. The corrected version of STL file that you provided above is working fine in PS (no visible error on the sliced object)

Would maybe good to include this king of STL fixing in PS ?

thanks !

If you are on windows 10 you can right click the model and use the fix through netfabb option which is built into PS already.
