Gantry Installation

Before installation, look at the bottom set of gantry Gantry wheels.
The bottom wheels are spring-loaded, the top wheels are on a center-pivot.

Move the top set of wheels as needed for ease of installation (picture shows gantry Gantry being put on rail from back).

Before installation, look at the top set of gantry Gantry wheels.
Both sets of wheels are spring-loaded.

Wheels may need to be eased over the rails (picture shows gantry Gantry being put on rail from back).

Hold the gantry Gantry near the left side of the CMC and line up the upper then lower wheels of the gantry Gantry to the center channel of the board Board rails.

Info
NOTE: Installation is easier if you line up the upper wheels first, then slide the lower wheels onto the rail. Sometimes having a second person for this step helps. Do not cut the tie wraps (zip-ties) on the belts until you have the Gantry on the board Board assembly. It is much easier not having to deal with two dangling belts.

Carefully ease the gantry Gantry onto the left side of the rails, taking care that all of the wheels line up.
Upper and lower gantry Gantry ends must be slid on at the same time.
Make sure that the drive belt Drive Belt lies within the channel on either side and is not pinched between the gantry Gantry and the rail.
Roll the gantry Gantry to the far right of the board Board and back to the left to make sure it moves smoothly.
