  • What are the EN connections used for on the QJ8060 motor driver? I notice that your video seems to leave them unconnected.

    The EN terminal on the QJ8060 driver and all of our other stepping motor drivers is the enable terminal. We don't use this terminal and the driver will function properly if left unconnected.

  • What gauge wire between the VFD and the 2.2K spindle? The spindle connection posts are very tiny, equivalent to 18 gauge, but that seems too small. What do you use?

    The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

    The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

    Currently we use 20AWG 4 conductor.

  • What would be your recommendation for "power supply 2 (24vdc)" connecting to USB motion card? Are there any videos explaining it's connection to the relay coil? (not quite sure what relay coil is)

    A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

    If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

    The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

  • Do your cnc machine kits include all of the components to make a working machine?

    Our kits include all of the parts needed to put a whole working machine together. However, understand that the kits are quite advanced and require a good level of mechanical competence to be completed correctly. We offer assembled machines for those that can't assemble these machines due to their complexity and need for fastening the overall components in a way that there is good smooth and tight motion, minimizing backlash to the fullest.

    We do have a few kits that you need to supply the table which include the greenBull 4x,5x and 6x, and the blackFoot. The tables would be far to large and heavy to ship. Our greenBull Kit is our best selling machine. All of the other machines are all inclusive.

  • Its mentioned that your USB Breakout board is based on Planet-CNC's MK1 board. Planet-CNC on their forums mention that they've discontinued their MK1 because of a low buffer memory which caused jitters and jerks in the machine? Am I likely to face a similar problem with your board?

    Dealing with our USB BoB, it is really similar to the MK1 board, but is also loosely based on their DIY board as well. We have not seen that much of jitters or jerks, that we have noticed here while fabricating and testing the boards. We have not heard that many issues dealing with the board about abnormalities in running, unless we have not been notified in regards to customers who have used them under continuous use.

  • I purchased the 4.0kw spindle and VFD a while back, and have just installed a PMDX-107 controller... do you have any examples of the wiring connections for the SL-240EE to PMDX-107?

    If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

    If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

    PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
    PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
    PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
    PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
    PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

    Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

  • I would like to know if your breakout board and driver boards are compatible with MAC OS X working with Sketch Up pro using SketchUcam ?

    SketchUcam will output gcode which standard CNC control software will typically interpret, execute and control CNC machines. So, there is no problem using SketchUcam. However, our CNC machine control software that use our CNC machine interface boards require Windows OS, of Linux. The Mach3 USB board will only run with Mach3 control software which runs under the Windows OS. The parallel breakout board can run under Windows or Linux OS and the computer must contain a parallel port.

  • I'm going to use 2 stepper motors for my X-axis. Can I use the same connections on the B/O board to do this knowing I will need 2 separate driver boards.

    Yes, absolutely. If you need two motors for a single axis, you will want to use the same terminals for pulse and direction from the breakout board.

    More specifically, you will wire the step/pulse pin to both drivers, and the direction pin to both drivers. If the motors need to turn in different directions, simply swap the A and B coil connections on one of the motors.

  • I have an engine NEMA 34 from Y axis on my green bull that do not response, I already check connections and everything seems to be OK, how can I check that the motor it's working properly or not?

    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.

  • I would like to make a handheld remote for the USB CNC Board using a joystick instead of momentary switches. Could you suggest one that will work with your board.

    The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.

  • Where can I find the book many of the others have mentioned in their question?

    We do not offer any free plans. We offer the CNC Scratch Build Kit which includes plans to build a CNC machine from scratch. You can find more information about this by clicking on this link https://buildyourcnc.com/cnckitintro.aspx

    Additional Information:
    WTF!! It says right on your utube page free plans available. I'll paste it from Utube right here.(DIY CNC Router for Under $900 - Free Plans Available) Very misleading, I spent a lot of time looking for this stuff and am lucky I found this because apparently none of its available for free. Very misleading, dishonest sales tactics. I'm sure you've made money conning honest people out of there money but your not gonna get shit from me. After reading what other people here have written, and the fact that you lie about the cost, at least on UTUBE, It is clear your a liar and a piece of shit. carry on though by all means and continue making money being a liar.

  • 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.

  • Using your USB control board, is it possible to install and use a Z axis touch plate? If yes, what board connections would it be installed to?
  • 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.
