  • Does the 2in flexible strip brush also come in 4in lengths for the bristle?

    At this time, we only have 2 inch bristle length. How would you apply the 4 inch bristle? Would it be used for a CNC machine, or another application? We might be able to supply this longer bristly length if we can see a good market for it.

  • What is the width of your strip brushes?

    The strip brush is .2 inches (5.23 mm) wide, so a slot of that width or slightly wider will work. We use a .25 inch groove and use glue to adhere the strip brushes in our dust shoe.

    The material of the bristles and the strip that holds the bristles are nylon.

  • GREENBULL 5X10 X AXIS SHUTTERS

    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.

  • Greenbull 6x (6'x12') table dimensions

    For the 6'x12' greenBull table dimensions, the table width for the greenBull table must be 80.078" (6.67' or 203.398 cm) and must overhang the underside structure by 1-1/2" to make room for the rails and this overhang portion should be 3/4" thick. The length can be variable, but remember that the gantry takes up some of that space, so add about 34 inches to make room of the gantry and the connecting hardware for the roller chain on the four corners. We recommend if you want a full 12 feet of travel, the table must be at least 178 inches.

  • 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.

  • PLANS GREENBULL

    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.

  • 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).

  • CAN THE GREENBULL CUT 18MM BIRCH IN ONE PASS?

    If you use the 2.2kW spindle, it can cut at 3/4 inch or 19 mm deep with at least a 1/4" cutting diameter single flute end mill. You will get better results with larger diameter end mills, but that is the worst case scenario. I still recommend doing a finishing pass on the edge to make sure everything is perfect.

  • can you ship a greenbull of blackfoot to japan

    You can determine if the country is serviceable by:
    - selecting the items you want to purchase on the website
    - go to the cart (shopping cart top left of any webpage)
    - log in, or register
    - Enter the address and click on calculate shipping.

    The webpage will return the direct rates and whether your area is serviced or not. Feel free to enter any address as long as you are able to receive the package from that address.

    Additional Information:
    I did that and got two options: UPS ($1400) or FEDEX ($3800). Maybe FEDEX is already including the customs fees and import taxes, I don't know. I am afraid of buying it and having problems with customs later. That is why I asked if you guys have ever sent any machine to Brazil just to check if everything went fine with customs.
