Kinda disappointing.
My first Neptune 4 plus is a beast and never lets me down. The second one I purchased was a used one from the Elegoo website. It was supposed to be in Good condition but it has been an absolute nightmare. Nothing stays tight so nothing stays level. It was missing screws when it arrived but luckily it came with a giant bag of mixed screws and parts for a Neptune 4 Max. The second machine is a headache and I’m looking to unload it for something better.
