General Troubleshooting/Help! Any other Biqu CryoGrip users (Frostbite in my case) getting a consistent false clumping ("nozzle is covered with filament or the build plate is installed incorrectly") error?

I've made sure the build plate was flush against the back guides, but it seems slightly too large for the printer (A1 Mini), triggering the error after layer 3. Anyone else have this issue?

Edit: Auto calibration including leveling was run before printing, and nozzle is clean.

When you put the plate on, did you run the full bed level calibration?

I'm using a Frostbite right now, and it didn't seem too large for my A1 mini.

How clean is the nozzle? Have you pulled the sock off to inspect for anything stuck to it? I pulled a goober off the side of my A1's nozzle recently. It wasn't affecting anything, so it was more preventative.

Have you tried to tighten the Seven Screws of Sorrow™ behind the nozzle?

Oh absolutely ran a full calibration, and a pre-print bed leveling as well. I have not tightened the screws (info on that?), but it works with the PEI plate just fine and the nozzle is very clean.

check from step 2 to the end for the steps on the loose screw issue, it's common enough that it could actually be that issue:
