Question #: 13549

Question: WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?

Current Solution

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.

  • table dimensions and clearance for 4' x 8' greenbull (torsion box)?

    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.

  • 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).

    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.

  • Do you sell plans (dimensions of parts, or even g-code) for me to build a 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.
