dual drive x-axis?

[fasteddy]

The cable design looks funky! But I am still unconvinced by using an active system, I would be concerned about slippage, stretching etc.. Not sure if I have uploaded the image properly in this reply, but if I have you will see that I have added two tracks under, and attached to the bed. There are bearing runners attached to the inside of the gantry base that locate onto the tracks.

Have not drawn it yet (have not finished designing it) but the base of the unit (the whole CNC will sit on top of it), will also have another pair of tracks that will fit to the bottom of unit, that will locate to a further pair of bearing runners attached to the underside of the gantry for further stabilization...

Hope this is clear, if not ask away and will try to further clarify it. I like this principle as it is passive and cheap..

Have to apologize for offering the link on my first post of the build videos that first wowed me into all of this... This is the proper link http://buildyourcnc.com/step1.aspx (cant seem to make it a link, having one of those days...) which shows every step of the build in videos (best watched at 2am when web traffic is light, yawn...)
