My very first build using mostly 80/20 extruded aluminum...
Hello everyone,
I am in the process of designing/building my very first CNC router that I plan on using mainly for woodworking. I have visited these forums many times and have found them invaluable but with no experience, have not contributed yet until now. I want my machine to be able route 2' x 4' sheets of wood with about 8" of Z axis travel.
Here is the core components of my machine so far:
Base assembly (X-axis):
- 2040 80/20 extruded aluminum frame
- 2 15mm Hiwin rails
- 4 15mm Hiwin blocks
- 1/2-10 60" single-start acme lead screw
- Delrin nut
- Nema 34 stepper motor (TBD)
Table assembly:
- 2020 80/20 extruded aluminum frame
Gantry Assembly (Y-axis)
- 2040 80/20 extruded aluminum frame
- 2 15mm Hiwin rails
- 2 15mm Hiwin blocks
- 1/2-10 48" aceme lead screw
- Delrin nut
- Nema 34 stepper motor (TBD)
Z-axis:
TBD
I obtained most of the extruded aluminum and Hiwin blocks/rails from:

I obtained most of the miscellaneous hardware from:

I obtained the acme lead screw/nuts from:

Attached are pictures of my design so far. I will post pictures later of the progress building the machine later tonight.
Drive 2 screws for the price of one (motor)!
gjhammer,
You can drive 2 screws with one motor. There are two ways to accomplish this:
1) Center mount the motor and drive both screws with belt & pulley.
2) Direct drive one motor and use belt & pulley to drive 2nd screw.
Just something to think about (not that there isn't enough to sort out already).
