Thank you for the comment!
You can see the parts in the pictures in the post. Yes, as far as I can tell, only a few layers were printed, then I lost adhesion. The build did stay on the tank’s floor, from which I had to scrape it off. The machine kept going until “finished”, but did not print anything for more than 90% of the printing process.
I will try angling the parts next time, did not think it was necessary since the first test print, which was not angled, went so well.

Thanks for the suggestion! Just trying to understand, why would reducing the exposure time for the bottom layer help with adhesion?

No worries, I had no idea what TSMC even is and was confused by these settings having two different numbers, but now that you’ve mentioned it I was able to Google it and I think I understand now.
Anyway, thanks for the suggestion and for helping me learn, I might try that!

It completed, but was stuck to the resin tank. No errors this time.
