Help wanted design laser X-axis

That clamping system looks brilliant. G.

You could try Fenner Drives trantorque keyless bushes or Lenze ETP Mini locking bushes. I have used both types and both are very good.

Thanks Web Goblin both look like good options, what was the smallest diameter of shaft you have used these on?

Searching for mini linear rails I can across this video. check out the 3mm rail in the bottom right corner.

[Web Goblin]

I think the smallest I used was on a 10mm shaft. What I really liked about them apart from ease of fitting is that they are easily adjustable along the shaft to line up a pair of pulleys.

I have to be honest it all seems a rather expensive solution to move something that is relatively light?w why not go for something like the IGUS linear type rails and slides? very rigid and light and designed for this type of application?

Have a look at this

igus® CNC-controlled laser cutting machine

Igus is also a good choice, I have seen a few different laser cutters so far using Igus successfully. Comparing price and spec in terms of max speed and accerelation would be a route forward.
