Step 2: Connect the PTFE Tube

Reconnect the PTFE tube to both ends of the filament buffer.

Verifying Functionality

Turn on the printer, and use AMS to initiate a loading operation. If the loading process completes normally, the replacement was successful. Otherwise, check that the buffer’s connection cable and the PTFE tube are properly connected, then try again.
