1. This product provides the core extruder components, main control board, and various connectors, which need to be assembled by 3D printing the TPU feed assist module housing and frame.

2. The TPU feed assist module can be installed on either the left or right hotend:

• Installed on the right hotend : The left hotend can still be used normally, such as for printing PLA supports for TPU.
• Installed on the left hotend : Dual hotend printing is not supported, as the vertical movement of the left hotend may lead to unstable TPU feeding and increased risk of clogging.

3. Requires an external feeding system (e.g., AMS HT or a filament dryer with spool rotation). AMS auto-loading/unloading is not supported. When using AMS HT, feed the filament through the TPU output.

TPU printing, no more problems   

TPU printing is traditionally a challenge due to the filament's inherent elasticity and high friction. To ensure smooth extrusion, the feed path must be as short and direct as possible. The TPU feed assist module eliminates this problem by providing active and consistent filament boost. By stabilizing the feed and reducing friction, it offers the reliability and precision needed to achieve professional-grade TPU print results.
