Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

The roller chain lengths for the greenBull 4x is:

WHAT LENGTHS OF ROLLER CHAIN DO I USE FOR THE GREENBULL 4X CNC?

The greenBull 4X comes with all of the components and electronics to assemble the gantry of the machine. You will need to build the table. We provide the rails and roller chain for the X-axis (along the length of the table for full 8 feet of travel). You will need to provide some wire to connect the electronics and a computer to run the machine. You will also need to purchase the software that you will need to run the machine that matches how you will apply the machine. We suggest the mach3 control program. The CAM program is up to you as there are many options out there.

WHAT DOES THE GREENBULL KIT INCLUDE AND DO I NEED TO INCLUDE?

Only our greenBull CNC machines will be able to use the long Z-axis, due to structural construction of the greenBull over the blackFoot.
The height from the table top to the bottom of the gantry is: 4.25"

Both the maximum cutting height and diameter, will be dependent on the specific end mill/router bit you plan on using, since they can vary in length.
The maximum cutting height (useful to engrave or cut material)is: with spoil-board 3.875", without a spoil-board is 4.625"
The maximum diameter will (estimated) is: 3"

Specifically dealing with our greenBull long Z-axis CNC machines, depending on how you specifically design the table you can have more cutting height and a larger diameter clearance. If you only create a frame for the machine with a hollow center(adjustable midsection), allowing you to have a greater clearance.

the greenBull can handle cutting aluminum as long as the correct bit (end mill) is used and the bit is cooled frequently to prevent chips from melting and causing damage to the bit or warping the material.

If your axis shutters and will not move unless moved by another force, that sounds like your acceleration is set too high. Lower the acceleration until it works well, then lower it a bit more to have a margin of safety.

Users response:
I've lowered my acceleration to 1 in the StepCon program and it still shutters when I jog it, anything else I could check?

Buildyourcnc response:
IF that didn't work, try swapping the X and Y drivers. That way you will pinpoint if the issue is the driver. If the proplem persists, then there may be an issue with the motor itself.

Buildyourcnc response:
The X and Y drivers can be easily swapped by swapping only the motor wires.

- Remove the x-axis motor wires from the X driver.
- Remove the Y motor wires from the Y driver.
- Insert the X motor wires into the Y driver.
- Insert the Y motor wires into the X driver.

Buildyourcnc response:
Now the Y-axis will move the gantry. Test the Gantry movement by moving the Y axis using the up and down arrow keys (mach3).

Users response:
Problem is now solved, I switched the X and Y at the redFly and got the same problem, so then I undid the wires going to each motor and switched them there and it I had a bad solder point in the X axis connector, thank you for the help

Buildyourcnc response:
You're very welcome. We will make sure to thoroughly check the solder points on the cable connectors prior to a redFly delivery.

Here's a link to the blackTooth laser that we sell, https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx. It will vary depending which materials you are using, but keep in mind on how deep you are cutting since the blackTooth only cuts 1/4" inch(dept) at a time.

Additional Information:
We will be carrying a 8' x 4' laser cutter in the near future. We will also design an attachment for the GreenBull to contain a laser tube at the head of the machine to convert a greenBull into a laser cutter.
