Hi Zig,
Ideally, of course, it would be best to use the purpose made (fully supported) linear slides but unfortunately they come at a price. However, there are many that have successfully used the draw slides for their CNC build but be aware that they can have their disadvantage…
I use some miniature (high cost, professional) versions, for laser optics positioning (which work on the same principal) and although they are smooth and very low friction sooner or later the cage, containing the balls, gets out of step with the slide - then they become ‘high friction’ when the balls have to 'skid' in order for the slide to reach it’s end stop and reset the cage positioning.
Please keep posting details, pictures or video links of you build – we all like to see pictures.
