Assembly \ Installation

• Linear Rail Preparation

  • Remove the carriage from the rail
    • Lay the rail/carriage face down on a table.
    • Remove one of the carriage stops and set it aside.
    • Carefully remove the rail from the carriage by sliding it off. The bearing balls should remain in the carriage. video
  • Clean the components
    • Soak the carriage and rail in IPA to remove all of the shipping protectant for 24 hours.
    • Wipe and fully dry the components.
  • Assemble the carriage
    • Place the bearing balls back into the carriage. If you lost some, or need more preload the rails listed use 3/32 solid chrome steel bearings (G25). NOTE: Add/remove bearing balls so that the rail almost moves freely under its own weight or only needs minimal force to move.
  • Lubricate the components
    • Use a lubricant that is recommended for linear rails and will withstand the expected chamber temperatures.
    • Carefully force the lubricant into the bearings, cycling them until well lubricated.
    • Install the carriage onto the rail.
    • Loosen the wiper screws on each side and position them so they clear debris from the rail, but don't cause additional friction.
    • Tighten the wiper screws so they remain in the optimal position.
    • Wipe any excess lubricant off of the carriage and rail.

• X Carriage

  • Install the 2 ea. M2x4x3.5 heat inserts on the bottom for mounting the heatbreak.
  • Install the 14 M3x4x5 heated inserts. NOTE: Install Heat inserts using a soldering iron at 260C.

• XY Joints Assembly

  • Follow the guide.
  • Install the rail into the XY Joints.
  • Install the 2 ea. M6 grub screws from the top to secure the rail to the joints.
