New printer

I replaced my old and bung Mars Pro yesterday with this, an Elegoo Mars 5. It cost me about $400 from Jaycars. I actually went in for a Mars 5 Ultra, but that's another $250 or so, and I didn't feel the pressing need for any of the fancy-schmancy extras.So far I haven't been able to get it to actually print anything, and what the exact problem is I do not know. Nothing sticks to the platen, though it does stick to the FEP.I vaguely remember having issues with the Mars Pro when I first got that, so I'm not giving up all hope just yet. However, it is borne in on me just how much 3d printing is not yet a mature consumer technology — they're so finicky, and you have to be a tinkerer to get the things running and keep them running. It's a magical technology, but it's pretty bloody hermetic magic.
