My last post was a shambles and I apologize, I wanted to get some feedback but did not have the time to do it properly.
This should be a more comprehensible post.
Lets begin, I started working operating cnc machines in 2007 and was bitten hard as soon as I found out I could actually build one for myself I started planning.
My first design was pretty basic a desktop design but I quickly realized that I wanted something larger, This was back in 2008 as I got my hands on a probotix 3 axis kit.

My next design was severely over complex and would have been difficult to access, I wont bather to much whit this design but I worked around whit it for close to 2 years because I was hung up at a above below support system for the X-axis.

Now back before the summer I was finally able to get hold of cheap material provider threw my workplace and started from scratch.
I wanted to build for stability and rigidity, Extruded aluminum profiles was the choice to go in my mind, easy to work whit and strong, my third design was a fairly straight forward gantry model, biggest difference from the majority would be using 4 guide rods instead of the traditional 2 on the X-axis.

As I continued I realized that 20mm guide rods would have a significant deflection and switched to fully supported rods and I made one major change and departure from the norm, on the Z-axis I made the guide rods be the moving part to increase rigidity when moving at full extension.

I also added an extra slide to each, mostly because I had extra from previousa projects and after tests there was a noticeable gain in stability.

Next up is going to be actual build pictures.
