  • 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 IS THE FORMULA TO DETERMINE STEPS PER INCH OR RESOLUTION FOR EACH AXIS?

    The formula and calculation is a starting point to get into the area of steps per inch. You will then need to use the mach3 calibration utility to get the exact steps per inch.

    Formula:
    step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)
    if microstepping is set at 16 (1/16 on the driver) then and you are using a sprocket and chain with a pitch of .25 inches and 12 teeth on the drive sprocket
    = (200 * 16) / (12 * .25)
    = 3200 / 3
    = 1066.666 steps per inch

    For lead screw that has a travel of .5 inches at one turn like the 5 start 1/2 inch lead screw and using 4 microsteps per step (1/4):
    = (200 * 4) / (.5)
    = 800 / .5
    = 1600 steps per inch

    Remember to use the mach3 calibration wizard and double check the driver microstep setting.

  • MY MACHINE CUTTING THE WRONG SIZE PART

    In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

  • HOW DO I SQUARE MY CNC MACHINE OR GANTRY?

    I use a standard large "L" square used in construction. I run gantry up and down with the bit along one side of the square to make the square aligned with the x-axis. I then run the bit along the other edge and if I see space from the edge of the bit to the square, I adjust the gantry square by loosening and tightening the eye bolts that hold the chain at the ends of the table. Repeat as necessary to get the desired square.

  • WHAT IS THE DIFFERENCE IN A 2.5 AXIS MACHINE?

    An axis is a direction of motion controlled by the CNC machine control. It can be linear (motion along a straight line) or circular (a rotary motion). The number of axes a machine has determines it's machining capabilities. A 2.5 axis machine really has three moving axes, but only two axes can move together (most machines sold today are full three axis machines). For machining centers, a three axis machine will have three linear axes. A four or five axis machine will have three linear axes as well as one or two rotary axes.

    Note that 2.5 versus 3 axis has yet another context. 2.5 axis machining requires that the machine have three axes, but only two axes must be moving simultaneously at any one time. (Simple operations, like drilling and most milling, fall into this category). On the other hand 3-axis machining requires that all three axes be moving at the same time (More complex operations, like the machining of sculptured surfaces required in molds and airfoils, fall into this category.)

  • HOW LONG WOULD IT TAKE FOR MY TO BUILD A MACHINE?

    The length of time it will take to build a CNC machine kit is not an easy answer. There may be a wide array of circumstances that limit a persons abilities to build the cnc machine kit in an efficient timeframe; however, if you have moderate dexterity and moderately mechanically inclined, you should have no problem building one of our machines within one weekend if the project has very little downtime.
