The quick guide has a photo of what is purported to be the test model but it does not look like the gimbal:

Also, the guide says that the breakaway filament is to be used to print the test model, but I just used plain white and the component pieces of the gimbal rotate freely.

I suspect that at some point during development Snapmaker decided to change the test model, but the quick guide was not properly updated to reflect this.

I guess you are right. I did the calibration with normal pla too. Saving PVA for future 🔮.
