Question #: 889

Question: Is there an option for 4th axis on blackfoot?

Current Solution

You can add a head stock and tail stock on the blackFoot by designing the table in a way the head and tail stock is positioned at the correct level so the end mill will be at the correct position. The correct position will depend on the end mills that you will be using. The end mill should be centered to the center of the head stock jaw near the lowest z-axis position.

  • is there a option I can purchace the black toe 2x4 in a 2x8 format?

    When you purchase the blackToe 2'x4' CNC machine kit, you determine the length. The 4' is only the suggested length unless you purchase the optional table. Just construct a table that is 8' long similar to what this customer did:

  • my z axis action is reversed.help its a blackfoot

    If any axis is moving in the opposite direction, go into the Mach3 settings and first verify the hotkeys are set appropriately (example: Page Up for Z Axis up). If this does not solve the issue, check under Config>Ports and Pins> Motor Outputs: to verify all settings are correct (Pin and Port numbers and enabled/disabled signals).

  • 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.

  • The rods in my blackFoot gantry connected to the x-axis motor are bowing or bending.

    We are using the 1/2" rods in the gantry now. You can opt to purchase 1/2" rods and new gantry sides which will accept 1/2" ID bearings.

  • What electronics configuration is included with the blackfoot if I choose that option?

    There are three options on the blackFoot product page.

    Two options include either electronics that use the USB interface, or parallel interface. Both of these options include stepping motors (two 425 oz-in and one 651 oz-in), motor drivers (two 3.0 amp and one 6.0 amp), power supply and either a parallel breakout board, or USB breakout board. The USB interface must be used with the planet-cnc software. The parallel interface can be used in a wider variety of control software but will require a parallel port on your computer. If a parallel port doesn't exist, you can purchase a PCI parallel port adapter (for desktop computers only).

    The other option does not include electronics. This option is if you already have electronics, motors and drivers that will work with this machine, or you wish to purchase the redLeaf or redSprout assembled and plug and play CNC electronics and computer system.

  • Is there a BlackFoot laser cutter upgrade available?

    Currently the laser attachment is only available for the greenBull machine due to size constraints on the gantry.

  • BlackFoot CNC: Where should z-axis limit switches be placed?

    The limit switch for the z-axis should be placed in a location where nothing can interfere with CNC process, now for our blackFoot, referring to step 115(https://www.buildyourcnc.com/blackFoot48v40.aspx#prettyPhoto/120/) it will be placed 1-1/4"(may be adjusted) down from the top wood piece(vacuum holder). So contact will be made from the location of the anti-backlash nut wood piece and the limit switch stopping it from going to high.
