Grab the Y-axis gantries (wrapped in paper) and you’ll see four holes on each steel plate in a square formation. Add the wheel sub-assemblies to these holes just like how you just did it for the X-axis gantry, make sure that one is assembled as the mirror of the other.
On the Y-axis plates, there are two holes on the plate for the Delrin anti-backlash nuts. Line up the nuts and secure them to the plate using the M5-25mm screws. Note that they should be mounted on the same side as the Delrin v-wheels, and have the screw used for tensioning facing outwards.
Repeat the process on both sides.
Make sure you start with the right Y-axis gantry.
Start by putting the M5-50mm screws and spacers onto the NEMA 23 motor as shown in the photo.
Carefully line up the screws into the four holes in the Y-axis gantry. Drop the motor, screws, and standoffs into place. Take note of the position of the motor connector and what side of the plate you are mounting it onto (the side with the wheels).
Use the four M5-nylock nuts to secure the M5-50mm screws.
Next, clip on the 3D printed Y-axis drag chain clip-on mount. We’ve found that it is easiest if you clip on one side onto the standoff, then swivel the other side onto the next standoff.
Once everything is finished getting put together, it should look like this!
