Aftermarket Mechanical TPU compatible modification system for Bambu AMS (Gen 2)

Compatible with P1S, X1C. If found to work with other machines let us know what you did.

Improve TPU feeding. Keep your OEM setup.

The AMS Pro Feed System is a precision-engineered bottom-end upgrade designed to solve common filament feeding issues—especially with TPU—without modifying your factory spring.

This is a clean mechanical alternative to popular spring mods, delivering consistent performance through refined geometry and controlled flexibility instead of trial-and-error tension changes.

Why Choose This Over Spring Mods?

  • No spring swapping or sourcing parts
  • Uses OEM components exactly as designed
  • Cleaner, repeatable, and more controlled solution

Comes in pack of 4

AMS TPU Setup & Usage Notes (Important)

For best results when using TPU with this upgrade:

  • Select “TPU for AMS” in your printer settings (not the standard TPU preset). This allows the printer to handle the material more reliably through the AMS system.
  • TPU performance can vary by brand — Sunlu TPU 95A has provided the most consistent results in testing.
  • Dry your filament before use. Moisture in TPU can cause feeding issues and inconsistent behavior.

Feeding & Setup Tips:

  • Start with the feeder fully open (no tension), then slowly tighten until the filament feeds smoothly without slipping or binding during retraction.
  • Using PTFE tubing with a smaller inner diameter (2.0–2.5mm ID) is highly recommended. TPU performs best with minimal movement and reduced internal space.

Due to the flexible nature of TPU, proper setup is important to ensure smooth feeding through the AMS system.
