Question: I’VE HEARD ABOUT A “POOR MAN’S COPYRIGHT.” WHAT IT?

Current Solution

The practice of sending a copy of your own work to yourself is sometimes called a “poor man’s copyright.” There is no provision in the copyright law regarding any such type of protection, and it is not a substitute for registration.

  • What metal sheets can I cut with the 80W laser? What thickness, alumium, steel? What about the 100 or 130W upgrades?

    Cutting metals with a CO2 laser is nearly impossible with just the laser by itself, no matter what the power. The wavelength that a CO2 laser outputs is not best for cutting metals.

    However, if you add oxygen as a cutting assist in the cutting process, metals can be cut, but we do not advise this as it is very dangerous.

  • My question about motor tuning for the blacktoe in Mach 3 was for the aceleration and velocity settings what are the recomended settings

    In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

    The steps per inch is dependent on the microstepping:
    Steps/Inch for the x and y
    Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
    Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
    steps/inch = 3200 / 3.5 = 914.28
    This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

    Velocity:
    Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

    Acceleration:
    Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

    The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

    Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

  • what is the thickest plywood you can cut with the lazer

    Our blackTooth laser cutter and engraver, will cut up too 1/4" wood, and acrylic. This will be the norm with our machine.
    Trying to cut a thicker material is possible but will need certain adjustments, ex. lowering the laser nozzle/focal point as the cut is made, lower and lower till the complete cut is made. We however do not recommend doing this with our machine!

  • My Spindle has 4 pins but only the U, V and W terminals at used for the Spindle. What about the 4th pin?

    The terminals of U, V and W from the VFD (Variable Frequency Drive) connects to the three coils (first three pins of the connector) of the spindle. The 4th pin in the spindle is typically not connected; however, bring a wire from the PE (Protective Earth or Earth Ground) from the VFD and connect it to one of the screws of the connector on the spindle. This will ground the body of the spindle.

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

    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.

  • DO NEED LIMIT SWITCHES, IF SO WHAT IS YOUR RECOMMENDATION?

    Limit switches are not really needed for this level of a machine, but if you do want to use them, then you will need to connect them with shielded cable and ground the shield at both ends and any other non-used wire in the cable. Limit switches are very susceptible to the motor interference. You will also need to adjust the debounce in the software you will use.

    2. Increase the capacity or the inverter if it is too small. Replace with an inverter that has a larger capacity
    3. Extend the ramp-up time
    4. Decrease the torque and increase the set value.
    5. Check if the motor is blocked and if there is a sudden change in load.
    6. Check if there is a sudden chance in the power supply voltage.
    7. Extend ramp down time
    9. DC breaking is too high. Decrease DC breaking
    10. Replace the inverter.
    11. Check to see if there is a short circuit with the connection wire of the motor.
    12. Extend the ramp-down time or add a breaking resistor.
    13. Check the mains supply voltage and insure there isn't ant sudden change in voltage.
    14. Send the inverter for repair.
    15. Check whether the input voltage is normal
    16. check whether there is a sudden change in load.
    17. Check whether there is any phase missing.
    18. Check the fan in the inverter. Is it spinning? Is it blocked? Does it have any foreign matter stuck on the fins of the fan? If so, clear the fan.
    19. Check the ambient temperature in the space that the inverter is placed.
    20. Check for adequate ventilation for the inverter where it is placed.
    21. Check for jamming or any sudden change with respect to mechanical load.
    22. Set the V/F curve correctly.
    23. The motor is too small.
    24. The motor is hot and the insulation of the motor degraded.
    25. Check if the voltage has a large variance.
    26. Check if there is a phase missing.
    27. Contact the supplier
