Bambu Studio Auto Flow Dynamics Calibration Failure (v1.8.4)

Bambu ABS filament failing to calibrate.

X1C puts down nice calibration lines however the result is always a failure when using Auto-Calibration.

Anyone else getting this?

I am too, which i why i cam here today. both of my printers are doing this.

My X1C is also doing this. It seems to go through the whole calibration process without actually extruding any material. The printer otherwise works and prints fine, just the auto flow calibration fails. I noticed this today after updating the firmware. I’m not sure if that is a coincidence or the cause.

Updated to v1.9.0.1 and its working now.
