Unable to diagnose print failure

Bambu Lab X Series Troubleshooting
1

I’m having some issues with print failures. Here’s what I’m working with:
-Bambu X1 Carbon
-Default bambu slicer settings (220 nozzle / 60 bed temp)
-Sunlu PLA filament

I am unsure what’s causing the issue. The only new variable recently was higher outdoor temperatures and humidity, but the relative humidity in my print farm is around 40% and 70 degree Fahrenheit.

This problem started about a week ago. Since then, I’ve tried clearing the nozzle, cleaning the extruder motor and gears, replacing the PFTE tube, using unopened filament, cleaning the printing bed, and I’m going to now try lubricating the lead screws. After cleaning the extruder gears, I managed to print the successful base shown in these photos. Immediately after that, I attempted to reprint the same model with the failure shown.

The failed model was attached to the bed, yet every layer after that was unattached to the layer beneath it. I have no idea what’s causing this or what other actions to take. Thank you!

Door open, top off?

I tried both. It still fails consistently the same way.

Update:

It appears there’s an issue with the temperature nozzle wires. There was an open circuit, but just barely. It had enough power to keep printing, but not enough to power to keep it at temp. I seated the wire back in place and got another successful print
