Question #: 196

Question: HOW A COPYRIGHT DIFFERENT FROM PATENT OR TRADEMARK?

Current Solution

Copyright protects original works of authorship, while a patent protects inventions or discoveries. Ideas and discoveries are not protected by the copyright law, although the way in which they are expressed may be. A trademark protects words, phrases, symbols, or designs identifying the source of the goods or services of one party and distinguishing them from those of others.

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

    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.

  • how do you automatically turn on the router with pokeys57cnc and mach3. Mach3 is different from the mach4 example "step by step guide".

    There is a video on this page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board
    that demonstrates the start and stop for a spindle with the Pokeys57CNC controller and Mach3. The video is titled, Spindle Start/Stop Control.

    If you are trying to start/stop a router rather than a spindle, all you need to do is apply the same concept of using the relay by passing the black (live) wire of the power cable through the relay. The Mach3 configuration is the same.

  • WHY SHOULD I REGISTER MY WORK IF COPYRIGHT PROTECTION AUTOMATIC?

    Registration is recommended for a number of reasons. Many choose to register their works because they wish to have the facts of their copyright on the public record and have a certificate of registration. Registered works may be eligible for statutory damages and attorney's fees in successful litigation. Finally, if registration occurs within 5 years of publication, it is considered prima facie evidence in a court of law.

  • How do I keep the lead screw from moving back and forth?

    The lead screw needs to be stabilized axially. The lead screw should turn, but not move any other way. The method to keep the lead screw stable is to use two bearings with ID (inside diameter) that match the diameter of the lead screw. The bearings are positioned before and after a stable structural part. A collar is positioned at one side of the bearing assembly and another collar, or end of a coupling is positioned at the other side of the bearing assembly.

  • Does the pokey57 use a different control cable
  • Same on the vlxl. Is the y stepper wired as in the diagram or is there a different diagram?

    Additional Information:
    As in, wire all 8 in pairs? Also, what would you suggest for lubrication on the rails?

    Additional Information:
    Yes, the color/color would be two separate wires going to a single terminal on the driver.

    The lubrication question would be great as a new question on the CSL.

    Also, the above link to the pdf isn't parsing correctly. The link to the pdf datasheet is in the description in the first link (link to the stepper motor).

  • Will the 1/2"5 start and 3/8" 5 start work in unison even though the turns per inch is different

    If the turns per inch on a lead screw is different, then the nut on the lead screw will move at a different velocity.

    Additional Information:
    Let me explain in more detail.

    Let's say you have two lead screws:

    - 1/2" 5 starts at 10 TPI = 2 turns per inch. (5 starts / 10 TPI = 1/2 inches per turn or 10 TPI / 5 Starts = 2 turns per inch.)

    - 3/8" 2 starts at 10 TPI = 5 turns per inch. (2 starts / 10 TPI = 1/5 inches per turn or 10 TPI / 2 starts = 5 turns per inch.)


    So, if two stepper motors (one connected to the 1/2" lead screw and the other connected to the 3/8" lead screw) turned 10 revolutions in 2 seconds, the 1/2" lead nut would travel 5 inches and the 3/8" lead nut would travel 2 inches at the 2 second mark.

  • Im in the market for a laser cutter with the ability to cut 8'x4' boards (different materials) and up to 5" height. I bought a greenbull 10'x5' a while back from you guys

    Here's a link to the blackTooth laser that we sell, https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx. It will vary depending which materials you are using, but keep in mind on how deep you are cutting since the blackTooth only cuts 1/4" inch(dept) at a time.

    Additional Information:
    We will be carrying a 8' x 4' laser cutter in the near future. We will also design an attachment for the GreenBull to contain a laser tube at the head of the machine to convert a greenBull into a laser cutter.

  • Can I increase the travel speed of my machine with different lead screws?

    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.

  • will the 651 oz. stepper motor you offer require a different power supply then for the original stepper motor I perched from you a few years back? I think it was a 24 V. unit????

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

  • If using a grease how does one protect leadscrews and rails from corian dust etc.

    If you have abrasive particles in the air from milling, you will want to periodically clean the mechanical parts like the lead screw and anti-backlash nuts. After cleaning the parts, all of the high friction parts that will be in constant contact, lubricating the parts with oils, grease or other lubricants. If the part is of steel material, that material will definitely need to be oiled, greased or lubricated so minimal oxidation will affect the exterior of the steel parts.

    The anti-backlash nut is made of Delrin, so petroleum chemicals like oils, grease or lubricants are ok to use. Abrasive particles may affect the anti-backlash nut over time; however, the spring and bushing of the anti-backlash nut will provide extensive use regardless of the wear.

  • HOW DO I WIRE FROM THE BREAKOUT BOARD TO DRIVER?

    CP+ to COM
    CP- to STEP
    CP+ to CW+ (small jumper wire)
    CW- to DIR

    Additional Information:
    If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

    Additional Information:
    If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

    On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.
