Printing not printing at all.

[Karloff]

Hey guys, so my printer went from printing decently, to not printing at all. I've done everything imaginable trying to fix it, up to and including regreasing it, updating the firmware, cleaning it, running test prints, and even discovering a small bit of resin in the main screw shaft and cleaning it with small amounts of IPA. None of it seems to be working, and now I'm worried my LCD screen is now not working. Does anyone have any suggestions? Thanks for your help in advance.
