We are having issues using silk pla as it’s getting chewed up by the feeder gears as it gets pulled into the AMS. We got to around 30% of a small mandala project (around 20 layers done out of 47 at 80mm diameter) and then it kept getting stuck. We were using 2 colors, and the copper seemed fine, just the white was getting chewed up to where bits of filament would stick out enough to get stuck. Not sure how to remedy this. Read somewhere that the gears might not bite hard enough as it’s softer - can the gears be adjusted in any way?
I don’t think its needed to adjust gears. My first attempt would be to lower the force that is needed to press the filament through the nozzle. You can try:
- printing in silent mode (half the speed)
- lowering the “max volumetric speed” value for this filament
- increase nozzle temperature by 10-20 degrees
If you can, please make a picture of the problem.

You should be using the PLA Silk preset, or at least lower the volumetric max tp 7.5 (what the preset uses). I print a lot using silk PLA in the AMS and have not seen a problem.

Be sure it’s dry. Different filaments act differently to moisture content. Most get brittle but some get soft.
I suspect it’s too many retractions in to short a distance. A mandala is a very complex design, I think it’s retracting a lot.
In the Cura slicer there’s are two settings called Minimum Retraction Distance and one called Maximum Retraction Count that are designed specifically for this issue in the Extruder. We don’t have the equivalent in Bambu Studio, and your problem is in the AMS, but the problem is the same issue.
Here are a few articles that address this, and stringing in general. More knowledge of plastics and how it’s handled in 3D printing is always helpful, eh? 
Take a couple of mins to read some on this.
To solve this, you’ll probably have to:
- Dry your filament, most manufactures have the time & temp on their Website. If not, check (this is odd) check on Amazon Reviews for the materials, someone may have asked a Q or a review might have the info.
- Slow down. A lot. Mandalas inherently take a looong time due to the complexity of the structure.
- Consider another material. All Slicers / Printers have their strengths and weaknesses. The X1C & P1P are fabulous printers, but like all machines, they’re not perfect, some jobs will stump them but print fine on other slicer / machine combinations.
This project is an extremely complex pattern with a huge number of retractions. You may have to reduce the number of colors in the model.
You managed to find an object that is inherently the on the extreme edge of what’s possible with 3D printing at this time. 
Good luck! EDIT: I can’t sppell
