Question #: 545

Question: WHAT CAUSES RINGING IN YOUR EAR AND HOW CAN YOU STOP IT?

Current Solution

Tinnitus . Learn to love it. No really you should see a doctor. Make sure. White noise will help you sleep when it gets loud.

Additional Information:
I learned, too late, that if a sudden loud event causes tinnitus, see an audiologist IMMEDIATELY. They can do something about it if addressed within a day or so.

Wear hearing protection...always. Loud noises trigger my tinnitus, and headphones and ear plugs (when out & about or at the movies, subway, etc) help tremendously. Mine are rated 33dB.

  • How can I convert from Xylotex to yours, four axis with limit switches. Have parallel PC and steppers on machine.

    Sure, the USB interface has a place for 4 axes of limit switches.

    Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

    A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

    Let me know if this information was helpful (or not) by adding information to this question. Thanks.

    User response:
    Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
    Thank you.

    buildyourcnc response:
    On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

    Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

    In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

    There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.

  • For cutting with the BlackTooth, what is the best type of clear plastic/acrylic to use, and can you recommend a source?

    The blackTooth will cut acrylic very easily. The type of acrylic (cast or extruded) is not important since the acrylic itself has 100% absorption with CO2 lasers. Any plastic retailer, even the home improvements stores will have sheets of acrylic.

    Avoid using plastics that will off-gas toxic and corrosive fumes. One example is PVC which is Polyvinyl Chloride. The burning of that material will exhaust chloride into the air and combine with the hydrogen in the air causing a chemical reaction yielding hydrochloric acid which is corrosive and highly toxic to humans.

    Always read the MSDS (Material Safety Data Sheet) for any material that you intend to burn with the CO2 laser.

  • HOW MUCH RADIATION GIVEN OFF BY A CELL PHONE AND THERE ANY WAY TO STOP THE FROM BEING ABSORBED INTO YOURSELF?

    Portable cell phones emit about 0.6 watts of radiofrequency energy, limited primarily by the power of the battery. As with any radiofrequency transmitter, there will be some amount of absorption in the human body; the amount depends on how close you are to the antenna. The Federal Communications Commission (FCC) limits the amount of radiofrequency energy which cell phones can deposit in the body to levels at which no health effects are to be expected. See an article on Cell Phone Safety on this website for more information.

  • Can you tell me what gauge wire is needed for limits switches and the spindle?

    The hookup wires you will need is 22 to 24 AWG stranded and shielded for the wiring of the limit switches and E_Stop. Our kit customers select various places for these switches, so we don't supply the wiring. If you don't use shielded cable, you will need to change the debounce setting in Mach3 (if that is the control program you are using).

    We typically use 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections.

  • Hi im interested in your new 4 x 8' laser , what is the thickest mdf sheet it can cut through ?

    We have not specifically tested for this data point, but a general rule of thumb is that an 80W CO2 laser can cut wood up to about 1/2 inch. Actual results depend on a number of variables -- power level used, amount of air assist, focal length of lens, number of passes, cutting speed -- and each of those has its own tradeoffs. We are planning to do some of these tests in the near future and post the results, so stay tuned for more in depth information.

  • I am asking what to set my steps per using your kit stepper motors and a 1/2"x13 lead screw with Mach3

    Here is the formula for steps/inch (steps per inch)

    Steps = how many steps for a full ration of the motor = standard motor steps x number of microsteps for each step
    Standard motor steps for our stepping motors is 200 steps per revolution.
    Microsteps are selected on the driver and are shown as full, 1/2, 1/4, 1/8, 1/16, 1/32 etc... Use the denominator for the number of microsteps per step.

    Inches = how far the travel is for one full rotation of the motor. For the 1/2" - 13 TPI (threads per inch), the travel length will be 1"/13 or .076923". So, for one revolution of the motor, the travel distance will be .076923 inches.

    So, the steps = 200 * microsteps, let's make this 1/4 just for the formula.
    The inches will be .076923. Plug those into the formula:
    Steps / inch = (200 * 4) / .076923 This can also be written as:
    200 * 4 / (1 / 13) = 10,400

  • What is the dimensions and material of the spine on your Strip brushes?

    The strip brush is .2 inches (5.23 mm) wide, so a slot of that width or slightly wider will work. We use a .25 inch groove and use glue to adhere the strip brushes in our dust shoe.

    The material of the bristles and the strip that holds the bristles are nylon.

  • What tolerance can I expect from your largest cnc machine and the laser cutter? Also, what depth can I get on the z axis?

    The largest CNC machine we make at this time (12/04/2015) is the GreenBull 6'x12' model. This model has 2 options for Z-axis travel.

    The short-z option has a total Z travel of 5.75 inches. From that you would subtract the length of the end mill used and the thickness of the spoil board to determine the maximum material thickness. (Example: If the end mill extends 1.25" from the collet and the spoil board is .75", then the material could be up to 5.75 - 1.25 - 0.75 = 3.75 inches in thickness). This is good for most sheet-type materials.

    The long-z option, used mainly for large 3D carvings, requires a custom frame and allows for up to 36" of travel.

    The tolerance of our machines, like any machine, depends on several variables. The major variables include the manufacturing tolerance, the type of machine control used, the precision of assembly, the thoroughness of maintenance, and the initial and ongoing calibration of the machine. Because we sell kits only most of these variables are outside our control. Therefore, we are hesitant to guarantee a certain level of tolerance for an end user. However, in our experience, tolerances of .001" are readily achievable with our machines.

  • how much would your vertical laser kit cost without the wood components and door plastic shipped to Canada

    Good question. I will need to add up the cost. However, the complete kit with the wood components will cost in the range of $300 to $500 using freight.

    Additional Information:
    I will add a price option on the Vertical Laser XL page that shows the assembly price without the wood structural parts. Are you wanting the rails included in the price?

    Additional Information:
    Hi, I was expecting an email answer, I did not know that you answered. Also I am in Fiji, not Canada. There is a flaw with your question form, It would not accept Fiji because we have no postal codes, so I put in my old Canadian code so that it would accept my question.

    Yes we would need the rails and any mechanical and electrical components. Our plan is to build it against a wall in a shipping container.

    If you do not have a suitable freight forwarder I can ask at this end because people frequently receive shipping containers.

    Thank you,

    George
