It was going very well until I started hearing loud thuds...

The nozzle was occasionally hitting parts of the model.

Bed adhesion was good, but at some point after at least 10 to 15 hits, the model detached itself from the bed...

The filament is calibrated, the nozzle zhop is at .6, and printing as well as acceleration is very slowed down, basically at HOHansen's 0.4 settings.

It's an A1 mini by the way.

I've had this problem on smaller miniatures, mainly on supports, but adjusting the z hop fixed it.

What could be causing this?

After following your suggestions, and printing with HOHansen's settings for the 0.4 mm nozzle, this is what I have.

I think it's getting there!

The banding on the cape, is almost invisible to the naked eye, but I'm certain it'll be fairly visible with some paint and a dry brush.

If anyone has more wisdom to share, please do!

Hey all!

I'm trying to identify this problem.

Is it under extrusion?

I did two cold pulls, I don't think I have a partial clog...

The filament is bambu lab basic and it went through the drier, so no moisture.

It was printed with ultra fine 0.08 default settings, 0.4 nozzle.

The printer (A1 mini) is a month old, with just a few prints.
