Title

The greenBull 4X spindle/laser machine is no longer sold as a kit or assembled.

The current design is the greenBull v2, available as an instant digital download with an optional laser gantry: greenBull v2 4'x8' plans. We stock the laser components, electronics, and mechanical parts to build it. This page is kept for reference.

The first CNC machine with a spindle and a laser. Large format heavy duty 4'X8' or longer perfect for standard 4'x8' sheet. This machine offers a sturdy gantry with the capability to mill light aluminum. The laser is perfect for precision cutting of thin materials. Also great for etching and engraving. Table Not Included. Big Business Production. Small Business Cost. The greenBull Heavy Duty CNC is a fully equipped CNC machine that will allow you to mill full length 4' x 8' sheets. Whether you're looking to automate the process for general woodworking applications, cabinetry, sign-making, construction, or milling other material like acrylic or light aluminum, the greenBull has the power to significantly reduce your production time. Important Things to Know:
  • The 4X used a standard amount of 50 feet of motor cable, which assumes the computer is placed right next to the machine.
  • The Spindle will require 12/3, 14/3, or 16/3 gauge cable for wiring from the inverter to the wall. You will also need 4 conductor wire for wiring the Spindle to the inverter as a 4th wire for ground is needed. It is important to understand the electrical requirements for wiring the Spindle, so for this reason we strongly recommend you check with a licensed electrician before attempting to wire it.

Technical Stuff
  • Actual table dimension for the 4'x8' are 55.25"x123" (this will create a 1 inch overhang on both sides).
  • The overall design has increased rigidity for the new routing/milling area but still maintains the aesthetics that are common across all of the machines on this site.
  • To guarantee that the gantry doesn't flex at all, a series of ribs were added within the gantry box making the entire gantry very similar to a torsion box.
  • The motors selected for all of the axes are NEMA 34 with 1/2" shafts (driven by 6.0 amp drivers).
  • The dust shoe is redesigned to provide better dust extraction capability.

Step 3
This is an example of the greenBull CNC with laser cutting through basswood. The main test here was not the laser cutting depth, but the smoke extraction method with an open machine. We found that the vacuum near the lasing was able to remove most of the smoke.
