Here are some of the most common methods used for moving the x/y/z axis in DIY CNC routers:

1. Hardened & ground thread ball screws.
2. Rolled thread ball screws.
3. ACME Leadscrew with direct drive or belt reduction drive.
4. UNC/UNF Leadscrew with direct drive or belt reduction drive.
5. Stationary Rack gear with motor driving the Pinion.
6. Stationary rubber Timing belt with motor driving the cog wheel.

Which ones did you use?

At the present I have my X axis 1/2" x 10 rolled ball screws, single ball nut.
My Y axis 1/4" chain and sprockets,
My Z axis 1/2" x10 acme, dumpster nut.
Works well together, but I think I might change the Y to ball screws, just for uniformity.

my z axis i plan to use TWIN ball screws(16mm) and single on my X axis. both will be gear driven.

What method did you use to move the x-y-z axis?

Hummm For now I use my hands to turn the handwheel, but not for long.... :rolleyes:


Sorry I can't resist to tell something stupid (chair)

Depends on the machine. The mill is ground and hardened all axis. My JGRO has your lead screws and nuts! My Widgetmaster clone may get China ball screws if they ever go for a cheap price. I refuse to pay $60 for a 6" ball screw though. Until something comes available, I'm looking at McMaster lead screws, and my rendition of a Dumpster nut on all axis.
