Construct the Gantry Structure
Step 1: Attach the plate to the column
For this part of the assembly you will need:
- The two gantry wheel plate assemblies
- Two 20mm x 60mm x 650mm aluminum extrusions
- A 3mm allen wrench

Slide the gantry column onto the gantry wheel plate assembly.

The bottom of the extrusion should be positioned just above the V-wheels. Align the notch on the back side of the gantry plate with the bottom of the gantry column.

Tighten the M5 x 10mm screws using a 3mm allen wrench.

Repeat the above steps for the second gantry wheel plate and aluminum extrusion.

Step 2: Attach the gantry corner brackets
For this step you will need:
- The two gantry wheel plate/column assemblies
- Two gantry corner plates
- Eight M5 x 10mm screws
- Eight M5 tee nuts
- A 3mm allen wrench
Lightly screw together four M5 x 10mm screws and M5 tee nuts on the long side of the gantry corner plate.
Slide the gantry corner plate onto the gantry column. The tee nuts should slide into the 20mm side of the column on the side that the gantry wheel plate protrudes. Furthermore, the protrusion of the corner plate should be on the same side of the column as the gantry wheel plate. Inspect the photos closely for reference.

Tighten the M5 x 10mm screws with the 3mm allen wrench.
Step 3: Repeat
Repeat the above steps for the second corner bracket and column. You should end up with two assemblies that are mirror images of each other. Inspect these photos closely to ensure your corner brackets are attached to the columns in the correct orientation.

Step 4: Attach the main beam to the columns
Slide the gantry columns onto the tracks.
![20160831_162654.jpg 20160831_162654.jpg](/v1.0/FarmBot-Genesis-V1.0/gantry/_images/20160831_162654.jpg)
Rest the gantry main beam on top of the gantry columns.
The main beam does not attach to the columns as you might expect!
As correct and tempting as it looks to attach the main beam to the columns in the orientation shown in the photo below, don’t do it! This is just a temporary resting spot for the main beam to ease the assembly process. Take your time with the next few steps so you don’t have to re-do anything.

Lift up the main beam and position it onto the front side of the corner bracket. Align the tee nuts with the lower two extrusion slots of the main beam and then insert and tighten the eight M5 x 10mm screws.

Repeat the above steps to attach the gantry main beam to the second corner bracket.
