Can the TPU Feed Assist Module be connected to the left hotend for use?\u003c\/p\u003e\n\u003cp\u003eYes. However, when the TPU Feed Assist Module is connected to the left hotend, only single-material printing is supported, and dual-hotend mixed printing is not available. This is because the left hotend needs to lift and lower during multi-material printing, which is likely to cause TPU filament clogging.\u003c\/p\u003e\n\u003cp\u003e2. When the assist module is connected to the right hotend, can the left hotend print support filaments?\u003c\/p\u003e\n\u003cp\u003eYes. The left hotend can print rigid support filaments without affecting the flexible filament printing of the right hotend.\u003c\/p\u003e\n\u003cp\u003e3. Is it necessary to update the printer to a specific firmware version to use this assist module?\u003c\/p\u003e\n\u003cp\u003eNo. The assist module is only powered by the printer and has no communication interaction with the printer.\u003c\/p\u003e\n\u003cp\u003e4. If the AMS connected to the printer has no extra interfaces, can the assist module be connected to the 6PIN interface on the AMS?\u003c\/p\u003e\n\u003cp\u003eYes. A 6PIN to 4PIN adapter is included in the kit, and the assist module can be powered by the 6PIN interface of the AMS through this adapter.\u003c\/p\u003e\n\u003cp\u003e5. What is the softest TPU filament model supported by the TPU Feed Assist Module?\u003c\/p\u003e\n\u003cp\u003e85A. Using TPU filament with a lower hardness may cause filament winding in the module.\u003c\/p\u003e\n\u003cp\u003e6. What is the hardest TPU filament model supported by the TPU Feed Assist Module?\u003c\/p\u003e\n\u003cp\u003e95A-HF. This module is optimized exclusively for flexible filaments. It is not recommended to use filaments with a hardness higher than 95A-HF, otherwise filament planing may occur.\u003c\/p\u003e\n\u003cp\u003e7. Must this module be used with the TPU high-flow hotend?\u003c\/p\u003e\n\u003cp\u003eNo. The TPU high-flow hotend is only compatible with H2D series printers and must be installed on the right hotend. The TPU Feed Assist Module can be used independently, and the printing effect is better when used with the high-flow hotend.\u003c\/p\u003e\n\u003ch3\u003eApplicable models\u003c\/h3\u003e\n\u003cp\u003eBambu Lab H2 Series , X series, P series\u003c\/p\u003e\n\u003ch3\u003eNotes：\u003c\/h3\u003e\n\u003cp\u003e1.When the left hotend of the H2D\/C is connected to the TPU Feed Assist Module, multi-color or multi-material printing is not supported (the left and right hotends cannot be used simultaneously). This is because the lifting movement of the left hotend will affect the feeding stability of the assist module, which in turn leads to extruder clogging.\u003c\/p\u003e\n\u003cp\u003e2.The TPU Feed Assist Module must be used with an external spool holder, and does not support the automatic loading and unloading function of AMS. It only supports manual feeding through the TPU-dedicated filament outlet of AMS HT.\u003c\/p\u003e\n\u003cp\u003e3.If any abnormality or malfunction occurs during use, please refer to the troubleshooting document: TPU Feed Assist Module - Common troubleshooting Steps.\u003c\/p\u003e\n\u003ch3\u003ePreparation\u003c\/h3\u003e\n\u003cp\u003eHardware List\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/wiki.bambulab.com\/general\/tpu-feed-assist-module\/004.jpg\" alt=\"004.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/4531\/2569\/files\/360_20260320104145.png?v=1773974540\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003ePrinted Parts List\u003c\/h3\u003e\n\u003cp\u003eIt is recommended to print the parts in PETG for better strength and durability.\u003cbr\u003eUse a dark color for the main body of the power module, and white for the light guide column ( Part No 4 in the image below ) to provide better light passtrough for the board LED.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/4531\/2569\/files\/360_20260320104607.png?v=1773974795\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eNote: The bracket model (No. 1) differs according to the 3D printer model, please ensure you print the correct bracket for your 3D printer.\u003c\/p\u003e\n\u003ch3\u003eTPU Feed Assist Module Installation\u003c\/h3\u003e\n\u003ch3\u003eStep 1.
