It didn't come with any resin.

Not sure where the warranty comment came from? I don't remember mentioning anything about a warranty.

I have downloaded and started using ChituBox, although you still have to run NanoDLP, unless there's a way to send to the printer straight from Chitu; the videos I've seen don't make it seem like that's the case though.

And I think that my LCD screen might actually be not working correctly. I did the LCD test, pressed the center all white square and it lit up, just didn't seem very bright. And then I pressed the grid test and it didn't give me a grid like I've seen in some videos, it just lit up exactly the same as the all white square test.
