I finally printed something again yesterday, and, as far as I can tell, the z-positioning was perfectly stable thanks to your suggestion.

Thanks a lot!

Thanks, gonna do that first before I start my next print. This sounds like a really plausible cause!

I’m new to both, FreeCAD and Blender, but what I’ve been doing up to now:

• Draw the to-measure parts in FreeCAD
• Export them as STL
• Import STL in Blender
• Add decorative elements there in Sculpt Mode.
• Profit

Need to enshittify it enough to make the AI features feel like an improvement.
