Yup, I think you're right that it plays those roles, and after a lot of trial and error, I'm also fairly convinced that it plays an important role in applying the perfect amount of clamping pressure on the rail. I could be wrong about this, but my bet is that the Dyson solution is meant to simultaneously address the issues you mentioned and optimal wheel position :)

@@StevenBennettMakes I could probably make a carriage plate out of some scrap aluminum if you haven’t made one yet.

Think it will be more then fine, 3D printers/CBC use this method and don’t seem to suffer from any of those issues.

I think the springs could be for releasing tension on the vertical axis when you move the horizontal axis. When you have 3 fixed wheels, you have to push in a precise angel in order not to give too much pressure on the vertical axis. I think the way the spring(s) are mounted, you have only two fixed wheels clamping the horizontal rod in stead of three en therefore decreasing the pressure on the standing rod, the vertical axis when sliding it. There must be a reason the spring loaded wheel is not vertical (pressing down), but in an angle. I expect the spring to be very loose. And are there not two of these springs. I think I see another groove. Maybe one for going left, the other for going right. I will watch the next video’s to see if this holds up. I’m curious to find out! Nice project!!

It looks like they have bearings so it's not running on the screws hopefully

@@kbshadepI will its generally a better practice to use shoulder screws than normal screws, but this is just something minor to the project.

Thanks Neal, I'm curious (and nervous) about the power delivery too! I have a couple ideas but I'll have to do some experimenting to figure out what works. A cost breakdown is a great idea, I'll definitely be thinking about ways that I can incorporate those details. I appreciate your feedback :)

I would like to get the file to

Thanks for checking out the project! 1. The m5 screws on the carriage are all 25mm 2. I'm going to try to get the (working) project files up in a public repo for everyone this week :) I'll let you know once it's up

@@StevenBennettMakes thank you I really appreciate it

You can find the current project files here: github.com/stevenbennett/DIYson Enjoy!

@@StevenBennettMakes thank you so much

Oh yeah? Interesting. Does the nut start to lose tension in your experience?

@@StevenBennettMakes not only to lose, losing is one problem but to get the really really Perfect tension that you in your case u really need and want to get this same experience of sliding try it on a test bench. Your are not chineses copy cat guy, you want to understand why Dyson did this right ? And the wheels will lose material with to much force.

I will not say that the openbuild stuff are bad I love the openbuilds stuff I have build with they stuff 3D printer, diy laser cuter and much more tools

Huh?
