Excessive time to generate g codes

Drew up a crochet rack for the wife on fusion. Basically a 288mm x 288mm x 20mm block with a 24 x 24 grid of 3.2mm holes in it. Fillet edges. I convert to stl and load into Luban. When I hit generate g codes it gets to 34% and just sits there. Normal print and parameters.

Never finishing the slice usually means there’s something wrong with your 3D mesh. I’m not advanced enough to have that problem, but my son ran into it when he was designing something more advanced.

Free STL Editors reviews some free tools that include STL repair functionality, but I haven’t used them myself.

If you can link the object, people better than me can offer suggestions.

Import the STL file in prusaslicer, it say immediately that the file is a correct mesh.

Grootte = size

1 shell is the good one.
Geen fouten gevonden = no faults.

anybody know how to creat drill pattern in CNC Luban?
