Where can the forum users find your model?

Your model does not have any joints applied at all! What do you want, someone to build it for you? After you try it on your own and add some joints and then have some issues, get back with the forum to ask for help on specific issues.

I read every scrap of your post but the model the forum needs it the one where you attempted to add joints to the assembly and then maybe had some issues. That is the model we need to help you!

You must have forgotten to save your model after adding the joints because I downloaded it again and there are still no assembly joints showing in the browser. I will try to download it again in a few minutes after you have had time to save.

I found it impossible to work with your main assembly because all the components are just hanging around. I find building assemblies to be much easier by building up component by component and placing joints or rigid groups as I go. So what I did was start a new assembly, grabbed components from your assembly and put them together. I chose to start where you started, on the cross slide. The wheels make for an interesting slider joint. I created an sub-assembly of the wheels, they are all the same, and in that assembly I placed a sketch point that remains in the same position on the circumference of the wheel no matter how it revolves. I used that point to apply my slider joints. I chose to apply these to the top two wheels due to their easy access. Take a look at the Screencast for other information. My reference model is attached.
You also have a habit of using a lot of Capture Positions and then leaving them in the model. This complicated the timeline terribly. As you build your assembly you cannot avoid capture positions but once the joint is secure, you can immediately DELETE the capture position that occurred when placing the joint.
As you continue, the forum users are more than willing to troubleshoot your issues but you have to give us something to work with first. By the way, attaching your model is an easier method for sharing. Simple open your model, select Export from the File menu and save the .f3d file to your hard drive. Then in you post use the Attachment section below to attach it. Your previous method is acceptable if you cannot do it the other way. You must admit that opening my model from being attached is a lot easier than going to a web link. Once you save my attached file to your hard drive, open Fusion 360 go to the File menu and select Open, then Open from my computer to load the file.

I made the revolve joints on the carriage capable of turning if you desired. Take a look at the animated screen capture on the first page of this blog to see what you can do if these joints are there. I did not finish it, just make the wheel capable of it later on. As to your second question the answer is YES. There is not a real good point to apply the slider joint to a wheel so I create one.
