HF nozzle failure deluxe

I use to say that I have zero problem, today my HF nozzle decided to wreck havoc.

What happened? Did the nozzle detach?

That’s honestly just as impressive as it is unfortunate. Was the nozzle not seated properly?

Is the nozzle clogged? If so, that’s the luckiest non-blob of death lol

The nozzle is a 0.4 HF nozzle. The issue occurred when it attempted to use the backup spool. There is no clog or any other obstruction.

It almost looks as if the block with the spring above the left nozzle got stuck and the filament escaped above the nozzle.

It has certainly done that — filament cutting no longer works. I’ll need to disassemble it and investigate the issue. No damage to the nozzle, though.
