  • how do I connect an 8 wire motor to a driver?

    If the motor has 8 wires, you will need to wire the stepper motor in bipolar parallel. This motor (425 oz-in) is wired as follows:

    Red and Blue wires to A+ on driver
    Yellow and Black wires to A- on driver
    White and Brown wires to B+ on driver
    Orange and Green wires to B- on driver

  • 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.

  • [55] My Nema 34 motor has different wiring colors, black blue red green instead of what is shown here. How do I wire it.

    Can you tell me the part number of the motor?

    An easy way to determine the coil pairs for 4 wire stepper motors (open-loop stepper motors only) is to connect two of the wires and try to spin the motor by hand. If the motor shaft turns with difficulty, those two wires belong to one of the coils. You can insert those two wires into the A+ and A- and the other two wires to B+ and B-. If the motor spins in the wrong direction, then you can either swap the two pairs at the driver, or toggle the "DIR active low" or "DIR Invert" in the CNC control software for that axis.

  • I have two nema 34 motors on my gantry and ordered a hex inverter, now I need to wire it correctly. What type of wiring hardware do I need and I will need a wiring diagram also. Please help.

    Have you considered reversing the A and B coils on one of the motors to the drivers? This will cause the motor to spin in the opposite direction. This is the easiest method. Using the HEX inverter is a more complex method and not recommended for simple driving tasks.

  • WIRING THE BLACKTOOTH LED PANEL TO PARALLEL BOB

    The blackTooth build instructions explain how to hook the four LED control panel to the USB breakout but not the Parallel BOB. Turns out it's very easy. Simply wire the corresponding LED cathodes (top pins on the display) to the matching CP- for the X, Y, and Z axises and wire the anodes (bottom pins) to the 5V terminals. For the on/off LED, wire the cathode to the G terminal on the laser power supply and the anode to the 5V laser supply terminal. Also, remove the 5V wire running from the Parallel BOB to the 5V terminal on the laser power supply. It is not needed and will cause the laser on/off light to always be on if the USB cable is connected.

  • need wiring diagram from rs485/breakout to VFD 110 v serial modbus

    It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

    The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

    You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

    Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

    You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
    - PD001 - value 2 - Enables with communication aspect of the VFD
    - PD002 - value 2 - Enables frequency control from the communcations port
    - PD163 - value 1 - VFD address
    - PD164 - value 1 - Baud rate of 9600 (speed of the communication)
    - PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

    Copy the dll file to the PlugIns folder of mach3.

    Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

    Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

    No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

    Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

    You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

  • My Nema 34 Step motors get fairly hot to the touch. Is that normal?

    If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

  • [48] This kit came with DM542 driver what are the dip switch settings for this with the usb interface

    The dip switches for the DM542 are as follows:

    Switches 1, 2, and 3 relate to the amp setting for the motor connected to the driver. Take a look at the datasheet for the motor that you have. If you are connecting the 425 oz-in NEMA 24 motor, the Amp setting should be around 2.8, so the dip switch setting is 1-on, 2-on, and 3-off. If you are using a NEMA34 motor from buildyourcnc.com, set the amp rating to the highest at 1-off, 2-off, and 3-off.

    Switch 4 is the setting for half or full current when the motor is at idle. You can set this to either full or half, unless you are using a rack and pinion and the axis is experiencing a load, like gravity. In that case, make sure switch 4 is on for full current.

    Switches 5 to 8 relate to the number of micro steps for each step. A stepper motor with a 1.8-degree step will have 200 steps per rotation. If you wish to increase the number of steps per rotation, you can set these switches so that you can have more granularity. This will depend on the mechanical configuration of the axis you are setting. For instance, if you are using a lead screw that has a lead of 1/2" travel per turn, you will want to set the axis to at least 1/4, or 800 steps per rotation. If your mechanical configuration is rack and pinion, or roller chain, you may want a higher micro stepping to achieve greater than 1000/inch resolution on that axis. For instance, if the axis has a drive sprocket with a roller chain that has 14 teeth and the tooth pitch is 1/4", use a 1/16 microstepping setting or 3200 steps per rotation.

  • I CANNOT INSTALL THE PARALLEL PORT DRIVER

    If you are unable to install the parallel port driver during the Mach3 installation process, it is most likely that you are running a 64-Bit version of Windows. Install a 32-Bit version, and retry the Mach3 installation.

  • 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.
