In this section we're going to assemble the X-Carriage. If you'd like to take a look at the 3D model, check out the GrabCad link in the description.
We're going to start by assembling the smooth idlers.
First insert a flathead screw into the recessed hole on the back of the X-carriage.
Then slide a spacer on, followed by a smooth idler. Make sure that the bearing side faces the spacer.
And then put a Nylock hex nut on.
Repeat this process for the second smooth idler.
First put the flathead screw through the X-carriage, then slide a spacer onto it.
Followed by the smooth idler, again making sure that the bearing side faces towards the spacer. Then put on a Nylock hex nut.
Note that there are two sizes of holes that will accept V-wheels on the X-carriage.
One of them is larger, that is for eccentric nuts. The other is smaller, that's for a Nylock hex nut.
We'll start by putting the top V-wheels on.
First put a screw through the hole from the outside...
...then slide a washer on it, then a V-wheel, and finally a hex nut.
Repeat this process for the remaining top three V-wheels.
Remember to put the screw through first, followed by a washer, then the V-wheel and then a hex nut.
Next we'll put the V-wheels with eccentric nuts onto the X-carriage.
Start by putting a screw through the V-wheel.
Align it with the wrench if you have to.
Then put a washer on the screw and put that through the larger hole of the X-carriage from the inside.
Now put an eccentric nut on the screw, making sure that the shoulder faces the X-carriage.
You'll want to make sure that the shoulder seats inside of the larger hole.
Eccentric nuts are an important part of the design of the X-Carve.
We'll use them to adjust the tension of the V-wheels on the MakerSlide throughout the machine.
Now we're going to adjust the eccentric nuts before we put the sub-assembly away for a minute.
You want to make sure that the bolt is all the way at the bottom of the extrusion.
Like so.
