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
It’s the same course. It’s there in the article.
