  • WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?

    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.

  • what are the motor setting for the greenbull

    In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

    The steps per inch is dependent on the microstepping:
    Steps/Inch for the x and y
    Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
    Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
    steps/inch = 3200 / 3.5 = 914.28
    This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

    Velocity:
    Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

    Acceleration:
    Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

    The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

    Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

  • What will be the amount of cable carrier that I will need for a greenBull 5x?

    To determine the length of cable carrier you will need for a single axis, measure the axis travel of your machine, divide this by 2 and add 12 inches. The radius of the curl is 2 inches.
    The amount of cable carrier needed for the CNC machines that we provide will be:

    blueChick: Total 4 Ft

    blackToe: Total 5 Ft

    blackFoot: Total 8 Ft

    greenLean: Total 8 Ft

    greenBull 5x: Total 10 Ft

  • I can't spot the differences between 4'x8' blackFoot and the 4'x8' greenBull (except for laser head option): please, can you tell me?

    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.

  • WHAT MATERIALS CAN THE GREENBULL MACHINE CUT? LASER ETCH?

    The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



    BYCNC Response:
    Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

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

    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 1/2" collet and nut do I use for the Greenbull with the 2KW spindle? I want to order the Onsrud Spoilboard surfacing cutter.
  • What is the Greenbull average power consumption in conjunction with 2.2KW spindle?

    You can determine you overall CNC machine current consumption be adding your spindle power plus your CNC motion power and the power that your computer requires.

    the formula to understand the current of each component is watts = volts x current, or W = V * I, or with some algebra, Current (I) = Watts (W) / Volts (V)

    For example:

    Spindle:
    The 2.2 kW = 2200 watts and you can find the current by taking the input voltage of 220 volt and get the current using the above formula: 2200 W / 220 V = 10 A (Amps)

    CNC motion electronics:
    The power supply that comes with our machines is generally 8.8 A

    Computer:
    The computer that you use to control the CNC machine will have a specific wattage. Let's say the watts is 500: 500 W / 110 V = 4.5 A

    Add them up: 10 A + 8.8 A + 4.5 A = 23.3 Amps

  • I'm planning on purchasing a Greenbull 5x (hybrid laser/spindel). What other expenses will I have for having a fully operationel machine

    You will need to make sure you have a 220 volt outlet near the machine. You will need some wire to connect the electronics unless you purchase the redFly, redLear or redSprout plug and play electronics. To maintain cooling for the spindle, you will need some silicone tubing to provide for water exchange within the spindle, a bucket and pump to pump the water. You will need a table built as per the dimensions on the greenBull page:
    https://www.buildyourcnc.com/greenBullCNCMachineKit.aspx

    For cutting material, you will need end mills which are consumables that will be purchased frequently as they wear.

  • Is it possible to get only the plans for the woodpieces for greenbull cnc

    The files and hardware option for our machines has been removed from the site due to the following reasons:
    Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
    The abuse of these files over the internet.
    Ultimately may reduce the sales of machines keeping us in business.
    Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.
