Installing the Gigabot X Feed Tube

The Gigabot X feed tube is a critical component in the transportation of printing material to the print head. Securely connecting the feed tube to the hopper and the feed throat is paramount for proper flow and prevention of its disassembly leading to spilled material. Below are the steps to install your feed tube with a secure connection.

Connecting the Feed Tube to the Hopper:

  1. Screw the GBX Hopper Screw Collar (part shown below) 3 inches onto the feed tube with the flange of the collar facing the short end of the tube.
