Just got some files for cutting a chain tray for the cables and will be building that as I build the new Y & Z axis. If this looks like a Marchant Dice Router you would be right. There are some minor upgrades and the steeper are from Zapp. The reason that I am wanting a taller Z is multi fold with the first reason being this:

I got it off ebay for just under £160 including shipping and it will allow me to do mouth pieces and a few other items with a whole lot better accuracy. back to the issue of the new axis, I am currently working them up in BobCAD V23 to get the idea and shape using dxf files of different types of extrusions. Would the current 16mm Trapezoid Lead screw be able to move solid Alli'? Any input on that front would be welcome as looking at some of the designs here and thinking that some where between 150 to 250mm Z travel would allow full use of the A axis once it is mounted. Which I am looking at a few options there as well. One option is to get another piece of the Alli' baseplate and have it cut longer to allow direct mounting of the axis to it ( Most likely over the X axis stepper motor). So that is that madness.

Control is via Mach3 and Roy's (DIYCNC) system 4 board using the EXMOD inserts current with the older model driver boards which you can see mounted to the side on a small post. I will be moving them all into an enclosure once have a bit more paid work done. I will post some video in another post as this is getting long.
