Just assembled my new Snapmaker 2.0 250. I did a great test print of a scale figure. So now I’ve imported my second project into Luban as both an .obj and .stl.
When I generate the g-code, a big swath disappears through the center of the model. I’m trying to understand why. It happens whether or not I have supports, and regardless of the quality (fast, normal, high).
Is it something having to do with the model, or with the slicer, or both?
Can’t really diagnose without seeing the stl or obj.
You’ll need to upload one of those for us to be able to help.
Have you tried slicing in Cura or Prusaslicer?

Here’s an .stl of the model. I tried getting Cura up and running, but it can’t find my Snapmaker, even when I enter the IP address. I thought I’d try to fix the model first, before moving to a different slicer.
Varna Library_MJ_3D Print Model.stl (2.8 MB)
Didn´t download stl, but seems faulty from the captures.
You can download the free autodesk meshmixer, it has many sanity checks for the stl files.
Also, to use CURA you have to save the .gcode file to disk, then open the gcode from luban and send the file from there.
Where did you get the model? Not all models are designed to be printed.
Appears to be really thin and hollow and doesn’t show up properly at all when I preview it on my mac.
When I import it into cura it shows up as only 20mm tall.
In meshmixer if I try to make solid it implodes.
I’m not great with repairing or modifying in meshmixer, so someone else will have to chime in with a way to fix it.
If something is too thin for Luban (or almost any slicer) to be able to print, it just ignores it. That could be your problem here.

Thanks. It’s my model. Was made for rendering, not printing. I likely need to reconstruct it. Was hoping that with supports etc it would be sturdy enough to print. It’s the first thing I’ve tried to print. I’ll rebuild it in Rhino.
It’s been a while since I used a 3D printer (10 years or so) so trying to remember all the parameters—technology has changed since then as well.
