Glad you got it working, interesting if the slicer itself was the problem.. When you're loading a file to the printer on my elegoo I'll be able to check the actual layer settings which is ultimately the key since that's how long the lcd will light up and cure the resin.
However supports and rafts are heavily influenced by the slicer so any issues there could be resolved by the slicer software.
Otherwise your hygiene cleaning all sounds like good practice regardless both to remove variables and maintenance.
Glad you got it sorted
From my perspective, if used for work, automatic security updates should be mandatory. Linux is damn impressive with live patch. With thousands or even tens of thousands of endpoints, it's negligent to not patch.
Features? Don't care. But security updates are essential in a large organisation.
The worst part of the Linux fan base is the users who hate forced updates, and also don't believe in AV. Ok on your home network that's not very risky compared to a corp network with a million student and staff personal information often with byo devices only a network segment away and APT groups targeting you because they know your reputation is worth something to ransom.
