Question #: 14522

Question: I want to fix the tramming issue, how can I measure this

Current Solution

You can measure the tramming angle by putting a long L shaped rod that will fit into the spindle's collet and affix a piece that will tough the table to the other end of the rod. Rotate the rod to determine how far out you are. The longer the rod, the more accurate the measurement will be.

  • how can I exhaust the blacktooth co2 laser cutter

    Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses.

    The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present.

  • Hi, wanted to know if the whiteAnt can produce PCBs? If so, wich is the precision?

    It is best to use a subtractive fabrication method, or a chemical method to product pcbs. The subtractive method generally requires the use of a CNC router with a pcb isolation routing end mill that generally has a very sharp point to remove the copper material. The chemically etching method is where an acid is used (ferric chloride, or another acid) to dissolve copper where needed.

    If there is a method where a highly conductive material, mixed with a plastic that maintains a conductive property after the mix, and can use the standard deposition extruder, then the whiteAnt will be able to make PCBs.

  • The spindle drops on our greenBull when power is turned off. How do we stop this?

    When you say the spindle drops, are you referring to the z-axis assembly that contains the spindle? If so, did you replace the lead screw and anti-backlash nut with a ball screw? Ball screws have extremely little friction and will cause an assembly under gravity to move down. If not, your lead screw and anti-backlash nut friction is extremely small, which is surprising and I have never seen this before. I would be interested in seeing a picture of the assembly. Please send a picture to techsupport@buildyourcnc.com so I can investigate this issue further.

    Additional Information:
    We haven't replaced or disassembled anything on the z-axis. I will try to get some photos sent to you. Are there any adjustments or recommendations for PM of the z-axis assembly?

  • HOW CAN THE ROUTER BE CONTROLLED OR CONNECTED TO ELECTRONICS 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 DO I DETERMINE THE AMOUNT OF SCREW WEIGTH THAT MY MOTOR CAN HANDLE

    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 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.

  • my x motor seems to ignore some movements causing it to be innacurate, how do i fix this?

    If one or more motor is not responding, please follow the troubleshooting directions below:

    For parallel Bob only! Make sure both the parallel and USB are connected.

    Re-check wiring, and connections for continuity (no breaks in the wires) and check for correct wiring locations from driver to BoB.
    Check dip switch settings on the driver.
    Check components, by swapping the motors (ex. y-axis motor to z or x-axis driver and z or x-axis motor to y-axis driver) to check if motor functions on another driver.
    Depending on software check step low active (mach 3) or invert pulse (planet-cnc) for the axis which is not responding.

  • The mach3 USB card requires 24V, how do I supply this?

    If you are using a spindle with a VFD, there is a 24 volt power supply that will provide the correct power for the V+ and V- on the Mach3 USB. The 12V option is only if you are using the limit switches on that side of the board, but if you are using it to control spindle speed and for the outputs, it's best to use a 24V power supply, or the 24V output on the VFD.

  • I want to increase my travel speeds. Can I change the lead screw to make my machine quicker?

    Changing your lead screws from a tight to a lose lead will definitely make your machine move faster as long as your stepper motors can handle the new torque that the lead screws will impose.

    Here is an example of a speed change from one lead screw to another:
    - Existing constants in the example: Stepper Motor steps 200, microstepping 1/8 making the total steps 200 * 8 = 1600.
    - Old lead screw: 1/2" allthread = 13 threads per inch (UNC)
    - New Lead Screw: 1/2" 5 starts, 10 TPI = 10 / 5 = 2 turns per inch

    Old lead screw would achieve a steps per inch of:
    1600 / (1 inch / 13 turns) = 20,800 steps per inch (You can also express the calculation as 1600 * 13 = 20,800 steps/inch)

    New lead screw would achieve a steps per inch of:
    1600 / (1 inch / 2 turns) = 3200 steps per inch

    You can see that the new lead screw requires far fewer steps to get to the same length of travel. If you maintained the same velocity for both examples, the new lead screw would travel the same distance 13/2 = 6.5 times faster. So, if your velocity was say 10 ipm, your new velocity would be 65 ipm. That would translate to far fewer burned edges and longer end mill life!

    Just remember, confirm that your motors will be able to handle the new lead screw. You will need to reduce the steps/inch causing the motor torque to increase quite a bit, so you should be fine.

  • Can’t find info about all three lead screws in you book or how to secure them

    The details will differ depending on the type of lead screw you use.

    For allthread lead screws, you will need the 1/2" square nut, 1/2" allthread lead screw, two 1/4" screws and nuts to hold the square nut in place, two 1/2" ID bearings, two standard 1/2" nuts, and one coupling hub.

    Attach the square nut to the nut support using the two 1/4" screw and nuts. The bearings will need to be inserted into the seats of the lower and upper part of the z-axis. Insert the lead screw through the top bearing. Use one of the standard 1/2" nuts and start threading it on the allthread screw just below the bearing. Lower the lead screw to the square nut and start to screw the lead screw into the square nut. Continue until the screw is near the lower bearing. Add another standard 1/2" nut to the screw and keep turning the screw until the screw just passes the lower bearing. Add the coupling hub to the top of the screw just above the upper bearing. Turn the lower and upper standard 1/2" nuts until they are snug against the bearing. If the standard 1/2" nuts become loosened, consider adding another nut to each end against the existing nut to keep them in place.

    For 1/2" acme 5 start lead screws, you will need to use an antibacklash nut in place of the square nut. This nut attaches with a flange using two #8 screws and nuts. The standard 1/2" nuts are replaced by clamping collars.
