Question #: 13632

Question: Can I make the router mount larger so my router fits?

Current Solution

If you are using a router that will not fit into the router mount, it is best to have the mount requested from us. The mounts were designed with the appropriate thickness of material for structural purposes and to maintain this structure under load.

  • Can the 40w Laser combo be mounted on the Black Foot 8x4 router?

    Currently, the 40W laser tube can be mounted on the greenBull and the blackTooth machine kits. The gantry on the blackFoot CNC machine kit has a height that would not be able to to support the laser tube very well. The laser tube needs a gantry that has linear rail bearings that are spread apart to minimize any transient response at exact stops and changes in direction.

  • My router runs in mirror image on the Y axis only so what can I do?

    If you are using Mach3, go into the config menu, , Ports and Pins, and click the motor outputs tab. On the line for the axis you want to change the direction, toggle the DirStepLowActive box. This will reverse the direction of the axis.

  • can my stepper motor lift the weight of my router?

    There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift.

    This formula uses Newtons (N) as it's final unit. Use this with the included radius (R) to determine the torque. Newtons can easily be converted to lbs or ounces using online conversions.

    Effort = Sf + (Load/(2 x pi x (R/p) x Se))

    where:
    p = pitch of the screw
    Se = screw efficiency = Standard lead screw will be between 20% (.2) and 40% (.4)
    Sf = static force. This is the force that is needed to start the movement. The number may be eliminated, but it is good to use a number in the 5 N to 20 N range.
    Load = the expected load that the effort will need to carry (i.e., the router and the included axis assembly that the motor will need to lift)
    R = radius of the lead screw


    This formula is based on the "law of the machine"

    The final effort amount with its unit of newtons and R will be the torque. For example, if the effort comes to 100 N (newtons) and the R is .5 inches, then you can assume that the effort is 50 N-in since it would take twice the effort to turn form the one inch mark from the center of the shaft.

    Example:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 13 = .08 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .08) x .2))
    Effort = 5 N + (90 N / (6.28 x 12.5 x .2))
    Effort = 5 N + (90 N / (15.7))
    Effort = 5 N + (5.73 N)
    Effort = 10.7 N = 2.4 lbs = 38.4 oz-in

    I am putting the oz-in on the end because the formula considers the distance from the center of the shaft to be one inch.

    Therefore, a 425 oz-in motor would be able to lift a 20.2 lb Router with its accompanying assembly. If the assembly and router is heavier, plug in the numbers and determine the effort required.

    With a bit of algebra, the formula can be rewritten to find the load:

    Load = (Effort - Sf) x (2 x pi x (R/p) x Se)

    Another formula that does not consider friction at all:

    Effort = (Load x p) / (2 x pi x R)

    Lets see if we get similar results:

    Effort = (20 lb x .08 inches) / (2 x 3.14 x 1)
    Effort = 1.6 / 6.28 = .255 lbs = 4.08 oz-in

    The results from both formulas appear to be very small because a 13 TPI screw will have enormous mechanical advantage.

    It is evident that the first formula that does consider friction that we are loosely estimating is far more conservative than the second formula. Either way, even the most conservative formula shows that the 425 oz-in motor will handle very large weights. If you are using a lead screw with only two turns per inch, .5 inch pitch, you can determine the requirements with the first formula.

    Example for a 10 TPI 5 start (2 turns per inch) lead screw:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 2 = .5 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .5) x .2))
    Effort = 5 N + (90 N / (6.28 x 2 x .2))
    Effort = 5 N + (90 N / (2.512))
    Effort = 5 N + (35.83 N)
    Effort = 40.828 N = 9.18 lbs = 146.88 oz-in

  • How do I adjust the gantry/router mount so it is perpendicular on a Blacktoe machine.

    Simple ways to get the z-axis router/spindle mount to be perpendicular to the table, you will have to get a level. Set the z-axis in place although you will have to remove it to tighten the top screws which will hold the top router/spindle mounts on the z-axis but you will be able to tighten the lower mount without having to remove the entire z-axis.

    Pending more info.

    Additional Information:
    It's not the Router that is out. It's the Z Axis, Y Axis not being perpendicular to the table. One of the problems was the double washer on the back side of the top rail V bearing. I took them off and ground down the screw head instead. Your instructions for building the Black Toe/Foot are NON EXISTENT, for want of a better word. I have buyers remorse.

    Additional Information:
    It's still not perpendicular but it's closer.

    Yes, if you want a laser on the machine, I would highly suggest that the laser be mounted on a separate gantry, similar to the following image:

    You would need to develop the gantry structure, but you can use this thread to work out the design with my guidance.

    You will need a laser tube, laser power supply, laser controller, mirrors, mirror mounts, lens and nozzle. You will also need some mechanical parts and some motors, drivers and power supplies for the drivers and the controller.

  • HOW CAN THE ROUTER BE CONTROLLED BY COMPUTER?

    The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

    If you are interested in the USB breakout board, you will need to get an independent relay board.

  • HOW CAN MOUNT THE EXTRUDER TO WHITEANT

    Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.
