It seems I'm too late to offer advice on your initial question, but I'm in the Elegoo family ane can say I've been enjoying my Neptune 3. There is a channel that you should check out on YouTube, guy goes by "The Feral Engineer", he has done a ton of work on these printers and if you find his profile on Reddit he was insanely fast to message me back with a question I had for him.

Happy printing!
