Hello,

I am looking to build my own CNC wood router. I currently own a used one that I purchased off someone else who built it. It isn't large enough and I don't particularly want to modify it since it will work for some of my smaller projects.

The current one uses I believe NEMA23 stepper motors for a 5 ft. (X-axis - 1 Stepper) x 6 ft. (Y-axis - 2 Stepper) x 6 in. (Z-axis - 1 Stepper) cut area using a palm router.

I have the mechanical side of the project locked down for the new one, but I need to select the stepper motors and the other electronics that will be compatible.

My General Specs:

Overall dimensions:

X = 6 ft. (overall) (1 stepper motor)
Y = 10 ft. (overall) (2 stepper motor)
Z = about 1 ft. (milling height) (1 stepper motor)

Router weight = 10 lbs. (per online spec)
Gantry = 15 - 20 lbs. prior to stepper motors and router (estimated, it may be less)

max required in / min. = 100 in. / min.
Average milling speed X - Y axis = 40 - 60 in / min.

Rack and gear combo for X and Y axis.
Screw for Z axis.

Any recommendations?
