  • hey, where can i see the steps how can i control 3 or 4 step motor? can i use the Axis Electronics Combo? or i need to connect controller?

    Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
    The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
    Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

  • Yawl sold me a ST-USB MOTION CARD I have surched all your electronics and can't find wring instructions I need to know where to connect X,Y and Z to this controler

    To connect the stepper motor drivers to the Mach3 USB interface card, you will need to follow the wiring diagram here: https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf
    which can be found here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board along with all of the other manuals associated with that interface card.

    Please note that the DC+ and DC- on that wiring diagram (power supply to thye stepper motor drivers) is not correct. The DC- is connected to GND on the drivers and the DC+ is connected to VCC on the drivers. Typically, the DC+ on the power supply is labeled V+ and the DC- is labeled either COM or V-.

    If you are having any issues with the wiring, please let me know and I will elaborate. Thanks.

  • HOW CAN THE ROUTER BE CONTROLLED OR CONNECTED TO ELECTRONICS COMPUTER?

    The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

    If you are interested in the USB breakout board, you will need to get an independent relay board.

  • WHERE ARE THE ELECTRONICS WIRING VIDEOS?

    The blackFoot CNC machine kit does not include a table. The table can be made as long or shot as you need. for instance, if you are looking for a travel of 4 fet x 4 feet, then the table will need to be about 6 feet long to get the full 4 feet of travel.

    The electronics are very straight forward using the connection diagram for the breakout board that you select. Use the videos for a general idea and then use the connection diagram to verify the correct connections for the interface of your choosing.

    Yes,the USB interface replaces the breakout board, but remember that you will need to use the planet-cnc software with the USB interface.

    Additional Information:
    The electronics does accompany the cnc machine kits as long as you select the option "with electronics". There are option to purchase the machines without electronics and that would be necessary if you either have your own electronics, or you prefer the plug and play cnc computer system we call the redLeaf, or redSprout. This will also be necessary if you prefer the electronics that use the USB interface rather than the parallel interface.

  • I recently purchased 3 axis electronics with the USB controller board. I'm trying to install an E-stop switch. Where do I connect that on the controller board?

    There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

    Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.

  • I was told you have some free CNC machine plans. I can't find them. Where are they?

    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.

  • How can I connect the Pokeys57CNC controller to a DRV8825 / A4988 expansion board?

    The DRV8825 driver IC by TI (Texas Instruments) has two main connections called STEP and DIR. These are the two main connections that you need to use to connect to the Pokeys57CNC controller. You also need to connect the positive digital voltage pin (5V) from the Pokeys57CNC controller's motor connector to both the reset and sleep pins. The GND pin from the Pokeys57CNC motor connector is connected to the GND pin of the DRV8825 driver. The enable pin of the DRV88525 can remain unconnected.

    There is a trimmer potentiometer on the DRV8825 that can increase or decrease the amperage setting for the motor. Depending on the DRV8825 board you purchased, there may be two pads to determine the amp setting while turning the trimmer (in the voltage setting on your multimeter).

    The A1 and A2 is connected to one of the motor's coils and B1 and B2 is connected to the other motor's coil. There is a pin on the DRV8825 called VMOT that you will connect to the power supply (max 45VDC) and the GND pin next to the VMOT is the V- for the same power supply.

    I hope this helps. If not, please add additional information on this thread.

    Additional Information:
    I followed (to the best of my ability) the instructions provided to my original question, but I did not receive successful results. When I followed the instructions and connected the ground pin from the Pokeys57CNC motor connector to the DRV8825 / A4988 expansion board, it stops the communication between the Pokeys57CNC board & the motors 1-3 that I had working previously. The DRV8825 / A4988 expansion board will be the fourth driver I am connecting to the Pokeys57CNC. The previous three drivers are PoStep-60's if that helps understand the issue.

    Prior to hooking up the ground pin (I used pin 10 from the Pokeys57CNC motor connector) to the DRV8825 / A4988 expansion boards ground pin, I was able to see the power being applied via the red LED being illuminated on the DRV8825 board; after this new configuration the light is not turning on.

    With the new recommended setup, I used a heat shrink solder piece to add the shunt for the connection to the sleep pin. The connection to the sleep pin is where I believe my issues are stemming from. I must be connecting it to the incorrect pin (within the 9 pin layout on the DRV8825 / A4988 expansion board). Do you have any reference to the 9 pin pinout on the A4988 expansion board? I double checked the pinout provided on the Texas Instruments page, but it only gives clarity to the pinouts on the DRV8825 board itself. After reviewing their documentation, I tried connecting the 5v (pin 9 from the Pokeys57CNC motor connection that's split to connect with the reset pin on the DRV8825 / A4988) wire directly to the terminal on the DRV8825 board and that didn't work either.

    Any help or clarification you can provide would be greatly appreciated!
