The Anycubic SP ACE Pro Buffer component is the main mechanical pressure distribution and position detection buffering system used in the Anycubic Color Engine (ACE Pro) unit in various series such as Kobra 3 Combo, V2 Combo, Max Combo, and S1 Combo. It functions as an intermediate pressure control node between the 4 internal supply channels and the printing tool.

• Dynamic spring absorption: It features 4 independent spring sliding channels that absorb mechanical stresses during high-speed color changes and retraction speeds.
• Integrated PCB optical position sensor: Includes a special PCB with infrared sensors that dynamically monitor the movement of the buffer slider, signaling the printer to increase or decrease the feed motor speeds.
• 4-in-1 PTFE guiding node: Connects four incoming PTFE tubes into a single distribution structure leading to the print head.
• Automatic aerodynamic quick-connect fittings: Built-in release clips hold the 1.75 mm diameter PTFE tube firmly while allowing quick disconnection during routine maintenance.
