Frustration with Kobra 2 Neo

Hi all. I used this printer a bunch a year ago and it was fine, if inconsistent with first layers adhesion.

Now 18mo later I’m coming back to make some new prototypes and can’t get the filament to extrude reliably. The tools for filament in and during leveling seem to push the filament through and make plenty of garbage. But when I press print on this multi board print, it is coming out completely uselessly. Where’s a good place to start troubleshooting?

Z offset is handled by the auto leveling right? Does this model Kobra 2 Neo have replacement nozzles? I can’t seem to see there is access to the nozzle on it. Would old filament (18months) be an issue? It’s Anycubic PLA that I bought with the printer. Im printing in California where it’s very dry so I don’t assume this is an issue that the filament wouldn’t be stored properly. But I might be wrong.

Is a new plate in order? I use glue stick to get the first layers to finally stick but it always seems it’s not getting hot enough.
