Computer and Control Box Options

Assembled Control Box redFly - With this option we install and wire the electronics in a custom-made control box. This is a great option if you want to save the time of wiring and mounting the electronics yourself.

Deluxe Assembled Control Box with Computer - Includes the control box option plus an integrated computer built into the control box. The computer features an Intel Pentium 3.0 GHz processor with 2GB of RAM and a Seagate 1TB Internal Hard Drive. This package includes Mach3 CNC software and a Windows 7 Professional license, which we will register in your name and pre-install on the computer for you.

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.

Important Things to Know:

  • The entire machine kit will take about 14-21 business days to produce and send out under normal circumstances. During busy periods this could increase to 20-30 business days. You can always contact us for an accurate estimate before purchasing. Assembled CNC Machines will take longer as they have to be produced to order. Expect a lead time of 3-4 weeks for assembled machines.
  • We include a standard amount of 50 feet of motor cable for the greenBull 4X. The recommended length is for systems in which the computer will be placed right next to the machine. If you plan on having the computer further away from the machine you will need to purchase longer cable lengths. If you are unsure about how many feet of cable you need, please call or email us and we will assist you.
  • 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.
