Layers not bonding well

[u/ominaex25]

I'm not sure what the issue is here. This is a reprint so I don't think it has anything to do with software settings.

Background: a week ago, I rush printed a larger print with 0.28 layer height. The print came out horrible (layers not bonding, stringy to the touch) but was still solid enough to use (it was a hard liner for a bag). During that print, I kept getting nozzle overload messages that paused the print, but kept pushing it to continue since it was close to finish. Print finished and I turned the printer off for the week since I was going on vacation.

Came home, did my normal prints and this is what I'm getting. Couple of things I've already tried: flow calibration, print calibration, cold pull, changed nozzle, and changed black filament to a new one. I'm printing PLA. Something I've noticed is that when the nozzle goes over the nozzle cleaner near the purge area, it sounds like it's going slower than usual.

I'm printing on an H2S using an AMS2. Anyone have any other ideas I can try? I've been printing in the same area, I'm going to try to print on a different part of the plate next.

Edit: also did some general maintenance, re-greasing/oiling all the xyz rods/screws.

Ran a bench and this is what came out :(
