I got the Inner Rails due to budget for this build, and they should be good for the main work I do which is engraving, but also cutting out signs. I’m not running my woodworking machines so dust should not be a problem for me. I also aim to make the machine enclosure to prevent dust entering the rail guides, and will be maintaining regularly like I do with my current machine.
The 3 styles of Rail Guides are
- Inner Sliding Rails – where the bearings run along the inside of a channel – https://s.click.aliexpress.com/e/_ATj6rD
- Outer Sliding Rails – bearings run outside the rail’s edge. and – https://s.click.aliexpress.com/e/_9JIRNZ
- Linear Guide Rails – a Steel guide along the axis keeps axis movement precise. – https://s.click.aliexpress.com/e/_A8ueSf
Dimensions and more information on these rail guides are below.
