Very strange problem with hot end level

[bibobus]

Hello. I’ve encountered what is truly the strangest problem I’ve ever had. I created a model in SolidWorks and exported it to an STL file with high quality. When the printer starts printing, it’s clear that the nozzle is at a nearly zero height. It starts scratching the bed, and because of the small gap, the plastic can’t even extrude. This issue is extremely strange, and I couldn’t pinpoint the cause even with the process of elimination. I’ve re-adjusted the nozzle position relative to the bed five times, and the offset seems to be correctly read by the sensor. Sometimes, the printer can’t even print a test line before starting the actual print due to the small gap.

Right now, I have a few main hypotheses:

1. A faulty model from SolidWorks (but I don’t understand what could be wrong with the STL file itself)
2. A bug in orca with this particular model
3. A software bug in the printer itself
4. It’s also possible that the issue lies in the settings of the Orca software, but I’m not experienced enough to spot the problem right away.

I’ll attach all the files, and if possible, could you try printing just one layer of my model? Maybe that will help me understand the cause.
