The DIY CNC Router Z Axis is the small carriage that goes up-and-down (the Z axis), and it holds the milling device (router, dremel, pen, plasma torch). This design is modular in that it can be easily adapted to many types of milling devices by removing a few bolts and sliding in the new mount.
Z Axis Assembly
Error in drawing: The anti-backlash assembly actually mounts on the other side of the Z Axis Rear (3) plate.

Photos of my build
Here are some images of my Z-Axis build
Close-up of the Front and Rear as well as the linear bearing. In the back you can see part of the Z-axis anti-backlash nut assembly. Probably not so important on the Z axis (since gravity already does a lot of the work).
A more ‘front on’ view. I have installed a spring-loaded pen assembly that I can bolt on the front of my Z axis to do test runs. A very high quality die grinder is mounted here – I use this for isolation routing PC boards and engraving. Here you can see the flexibility of the design. I can unbolt the die grinder & mount and bolt-in my 1/2 HP router in under 5 minutes. The wire on the die grinder is my ground for when I do isolation PCB routing and I use a touch probe and an auto leveler software.
Must another view for fun.
