Question #: 1062

Question: I need a Rigit Coupling that is 1/2" on one side and 5/16 on the other side.Can you get that for me?

Current Solution

We sell both coupling hubs that can be created to your specific needs. Which will be here https://www.buildyourcnc.com/couplings.aspx and would be the bottom coupling hub's, not the rigid couplings.

So essentially you would get the Single 1/2" Coupling Hub and the Single 1/4" Coupling Hub, and etc. for different combinations.

  • I need a resource, we bought 2 redfly systems and mach 4, We put one motor on for the x axis but cannot get it move. Can you direct us to some tutorial?

    Could you specify which breakout board you have? If you have a parallel port version, be sure that you have purchased the "legacy" parallel port version from Mach4. If this proves not to be the problem, please feel free to email us directly at techsuport@buildyourcnc.com or call 281-815-7701 for troubleshooting instructions.

  • Going to purchase a new laptop computer. Question. What is the minimal requirement for laptops running cnc planet software and other softwares that are needed?

    Your purchase of a laptop will depend on what CNC software and CNC interface you will be using. In most cases, CNC interfaces use a parallel port, or the interface will convert USB instructions into a form of parallel I/O pins. We provide both types of interfaces, but you will be required to use specific software packages compatible with the interface. The USB interface that we sell at the moment is only compatible with Planet-CNC software (which is very good software), and if the computer has a parallel port, you will have your choice of many software titles including (but not limited to) Mach3 and LinuxCNC.

    The hardware and processing performance is not as important. Computers with relatively slow processors (i.e. Pentium) can control a CNC machine and achieve good performance.

    If you intend using CAD and CAM on that computer, then you will want a more modern computer that will have a good amount of memory and processing power. You will need to refer to the software requirements for the minimum specifications.

  • I was wondering if it is at possible to get a autocadd drawing of the pieces that need to be built for your cnc hardware kit

    The files and hardware option for our machines has been removed from the site due to the following reasons:
    Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
    The abuse of these files over the internet.
    Ultimately may reduce the sales of machines keeping us in business.
    Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.

    Additional Information:
    NO, is not possible, I can help with the shipping cost

  • COULD YOU PLEASE EXPLAIN, IF IT'S TRUE, THAT HANDS-FREE CELL PHONE CAR MICROPHONES RADIATE MORE THAN ANY OTHER INSTRUMENT USED WITH THESE PHONES?

    Hands-free cell phone car microphones have been tested by the manufacturers and meet the current ANSI/IEEE (American National Standards Institute/Institute of Electrical and Electronics Engineers) standards for radiofrequency (RF) safety. These are the same standards that the Federal Communications Commission enforces under the Telecommunications Act of 1996, and they place limits on the specific absorption rate (SAR) of RF energy in the body. Recent inflammatory articles in the British press were not substantiated by testing at ISO-accredited testing facilities at Motorola. Manufacturers of cell phones are required under FCC regulations to assure that their products meet the SAR limits on both hand-held and hands-free units. Further information can be obtained on the Internet at The Center for Devices and Radiological Health (FDA information) or Office of Engineering and Technology (FCC information).

  • can you please specify how to connect the collar/nut and bearings to prevent the axial movement of lead screw. Do I have to put that next to the stepper motor /coupling assembling or on the other side where the lead screw comes out. Or is there any way I can make the flexible coupling rigid so it does not come out of the middle spider?

    You would use a combination of bearings and collars to prevent your lead screw or rod from being able to move back and forth. Without it being able to move back and forth, you shouldn't have the couplings coming apart, because the motor is solidly mounted and unable to move as well.

    I will try to draw a picture using symbols, with a key to define what each part is.

    --CB|--------------|BC}{M

    - = Lead Screw or Rod
    C = Collar
    B = Bearing
    | = Wood, the frame of your machine
    }{ = Coupling
    M = Motor

    On the example above you could replace the collar on the motor side with one half of the coupling, putting it right upside of the bearing to hold it in place instead. Like this:

    --CB|--------------|B}{M

    You could also place the bearings on the inside as follows:

    ----|BC----------CB|--}{M

  • I am almost done with the book build Cnc machine, but when I run the motors from mach 3, the 1/2" coupling comes out of the middle spider (the joiner which connects 1/4 and 1/2" coupling. How do I prevent this?

    The lead screw must be held in position axially. In other words, you don't want your lead screw to move back and forth at all. This is the only way the coupling hub that is attached to the end of the lead screw could be moving away from its coupling assembly. Depending on the lead screw that you are using, the combination of bearings and collars/nut keep the lead screw in place.

  • DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?

    The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

  • 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.

  • I HAVE A SIGN SHOP AND WE NEED CUT ALUMINUM, PLEXIGASS, FOAM AND OTHER MATERIALS FOR SIGNS. CAN YOU TELL ME WHAT MACHINE WE NEED? I LOOKING 4'X8' OR 5' X 10'

    The overall size of the machine, really depends on both the area available to you and also the overall size of material being used. Now our larger machines (blackFoot, greenBull, greenLean) can cut all the materials mentioned above, and if equipped with our 2.2kW spindle you will be accurate up to ten thousandths of an inch.
    Our greenBull machine does have an option for a long-z axis, that was especially designed to cut foam, but depending on the overall size it might not be a requirement for the specified request.

  • I'm planning a rack and pinion style gantry, and need clarification on how to slave a second stepper to the Y (or X). Can you direct me to that information for your products?

    There are two things to consider when using two stepping motors on a single axis. Since you want both motors to spin at the same rate and possibly in the same direction, you need to connect both motor drivers to the same breakout board pins. For example, if you want two motors on the x-axis and the x-axis pins on the breakout board are #2 for step and #3 for direction, the #2 will connect to the step (cp) terminal on each driver and the #3 will connect to the dir (cw) terminal on each driver.

    However, if the motors will be opposing (one motor will need to spin in the other direction), you will need to consider either flipping the rack on one side, or adding a circuit to invert the direction (#3) signal going to that driver.

  • I am building a wet plasma table for my shop that is 8'x 16'. I will need hardware and software. Please heko me wuth the list, My phone is 9124273734. I would like to talk with someone if possible. Thanks, Rus

    If you purchase the greenLean, you will get everything you need except a router, computer to operate the machine, and software to control the machine. You state that you have a computer. You can use this computer, but you will need to determine if it has a parallel port, or if you are going to need the USB controller option. As for the software, there are too many different options for you to choose from. We would not be able to tell you which to get, and how much it will cost you. This is a matter of preference. I can tell you, however, that you will need 3 types of software to complete a CNC project. You will need CAD software to design your design, CAM software to add tool paths and convert the design to g-code, and then control software to take the g-code and operate the machine.

  • Do you have a laser kit that can be fitted onto another brand CNC router?

    We don't have a laser kit to retrofit another CNC router other than ours, but we can create one. Some things that may help:

    - You are located close to use so we can work closely with you to implement to retrofit,
    - or you can provide very detailed drawings or measurements so we can use them to create the necessary parts for the kit.

    Other things that you need to understand:

    - A laser has a number of parts that will bulk up the head of the CNC router causing a bit more inertia which may require lowering the acceleration for smooth ramping up and down of the velocity

    - The bulk of the parts required for the laser may restrict the travel of the x and/or y axes.

    - The nozzle of the laser will be offset from the end mill of the spindle.

    Can you tell me the brand of the CNC router that you would like to stick a laser on? (you can answer by submitting additional information.
