Question #: 6853

Question: do you offer a 4' x 4' solution?

Current Solution

Depending on the specific kit, we can adjust the length of rails that are included with the kit to fit a 4' x 4' cutting area.
Specifically the blackFoot and the greenBull 4' x 8' machines will be a straight forward kit for a 4' x 4' cutting surface!

For custom size requests please email:
customerservice@buildyourcnc.com, for further assistance.

  • Do you offer custom CNC routers?

    Yes, we can design and produce custom CNC routers. You will need to contact us to discuss the customization that you would like.

  • Do you offer custom sized machines? I am looking for a 5'x5' version.

    Most of our CNC machines have the ability to be customized by length. The greenBull 5X for instance comes standard at 5' x 10' but it is really only the gantry width that is fixed. The length can be easily altered. If you are interested in receiving a custom quote, you can email sales@buildyourcnc.com.

  • What is the dot resolution (size) of the BlackTooth laser?

    The dot resolution of the blackTooth is a combination of two specifications of the machine:

    - The steps/inch (or steps/mm) which is the resolution but not the dot size
    - The size of the actual dot, which is not specifically related to the resolution.

    The steps per or resolution can actually be a range, since the driver microstepping can be modified.

    A simple formula can be used to determine the resolution:

    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) and you are using a pulley that has a pitch of .08 inches and 20 teeth on the drive sprocket

    = (200 steps * 16 microsteps) / (20 teeth * .08 inches)
    = 3200 steps / 1.6 inches
    = 2000 steps per inch

    To increase the resolution, just increase the microsteps on the driver.

    The actual dot size will depend on the lens you are using, the material being lased, the time period that the laser energy is applied to the material, and the focal height of the lens to the work surface material. The energy from the laser will converge to a point and create a dot on the surface (which is different than the kerf of the laser cut into the material).

    The dot will appear in different sizes depending on the material because, say wood, will burn causing a dot that burns the fibers of the wood and spreads a bit. The dot lased on the surface of a plastic, say Plexiglas, the dot will be smaller because the energy is absorbed only at that point, but since Plexiglas is a thermoplastic, a bit of the energy will melt the dot edges depending on the time frame (period) that the energy is applied to the surface.

    The focus of the laser energy from the lens looks like a cone converging to a point, then diverges outward after that point. Depending on the distance from the lens to the surface of the material, the dot will be bigger or smaller. You want to find focal point (where the energy is focused into a point). You can use the technique where you lay a material on a slope and lase that material along the slope to find the sweet spot (dot) and that will be your smallest dot, or kerf location. Remember that the kerf will widen or narrow within the material thickness depending on the focal length lens specification (the cone will be shorter or longer depending on the lens focal length).

  • Do you offer single shaft NEMA 34 steppers in your cnc kits?

    Our NEMA 34 motors have a dual shaft, meaning, there is a shaft that extends from the front and rear. Our machines use this dual shaft motor in our machines. Currently we do not sell/carry any of these motors with one-input shaft.

  • Lasercad resolution ppi

    The resolution of PPI (Pulses Per Inch or Pulses/Inch) for any laser is the velocity (feedrate) of the machine's head and the number of pulses that are generated during this process. Therefore, any number of PPI resolution can be achieved, so you have many options. The slower the feedrate and higher the pulses per second will yield a high PPI. Fast feedrate with low pulses per second will yield low PPI.

  • What is each axis' resolution for the blueChick in mm or µm?

    The resolution for any of our machines is based on the driver microsetting setting and the machanical parts used for each axis.

    For example:
    The blueChick uses 9 tooth drive sprockets for the x and y axes.
    To determine resolution use this formula:
    Resolution = steps / inch or the travel in steps for one revolution of the drive sprocket
    Steps = (motor steps) * (driver microsteps) or natural motor steps * microstepping setting on the driver
    Inches = t(ooth coun)t *( tooth pitch) or the number of teeth for the drive sprocket

    Resolution = ((motor steps) * (microsteps)) / (teeth * pitch)
    In this example, the microsteps is 16 and the pitch is .25 inches
    = (200 * 16) / (9 * .25")
    = 3200 / 2.25"
    = 1422.222 steps per inch

    For the z axis of the blueChick, the resolution is typically based on 4 micro steps and the travel for one turn of the motor is 1/2". Therefore:
    Resolution = (200 * 4) / .5"
    = 800 / .5"
    = 1600 steps per inch

  • 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.

  • Do you have a CNC machine plan available for a 4'x8' machine?

    All of our machines that are offered as a kit do not have a plans option. We do have a machine that is build form plans. The plans refer to the scratch build machine: http://www.buildyourcnc.com/cnckitintro.aspx and the one in the book "Build Your Own CNC Machine": http://www.buildyourcnc.com/Book.aspx
