Question #: 2216

Question: What else from you shop do I need to connect a #40 Drive Sprocket to my nema23 motor, its not so clear

Current Solution

You will need a collar or adapter to connect the ID of the #40 sprocket (0.622") and a 1/4" collar with our OD (0.674"). We currently do not have anything in this nature.


Additional Information:


Additional Information:
For a 1/4" input shaft the larger #40 sprocket, seem's pretty large for the 1/4" input shaft. So we recommend using a #25 sprocket and #25 roller chain with our NEMA-23 since it will be more compatible arrangement.

  • When using shielded wire from driver to stepper motor, where should I connect the shielding? Should it be ground on transformer or something/somewhere else?

    If you are using shielded wire between the motor and driver, the shielded portion (the reflective jacket within the insulated portion of the wire) and any spare wires, or stranded wire should all be grounded and be inserted into the GND terminal on the driver.

  • 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.

  • I purchased Mach3 from buildyourcnc dont know what verson i need to use in VCarve as the processor. There are 8 2/3Mach listed

    You will probably have post processors like the following listed:
    Mach2/3 ATC Arcs (inch)
    Mach2/3 ATC Arcs (mm)
    Mach2/3 Arcs (inch)
    Mach2/3 Arcs (mm)
    Mach2/3-WrapX2A ATC Arcs (inch)
    Mach2/3-WrapX2A ATC Arcs (mm)
    Mach2/3-WrapY2A ATC Arcs (inch)
    Mach2/3-WrapY2A ATC Arcs (mm)

    If you have an Automatic Tool Changer, use the post processor with the ATC in the name. For most applications and if you don't have an ATC (automatic tool changer), use the Mach2/3 Arcs (inch) or (mm) post processor.

  • I have the USB controller board and the 8825 step driver. I need a wiring diagram between the two. Specifically, what does the GND pin on the X-axis connect to? Also, what does the 5V pin on the driver connect to?

    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.

    You can find a wiring diagram here:
    https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/

    The CP terminal is wired to the step terminal on the 8825 step driver.
    The CW terminal is wired to the direction terminal on the 8825 step driver.
    The GND terminal connects to the GND on the 8825 step driver

    The 5V connector on the driver simply powers the logic side of the chip and needs to connect to VCC pin on the keyboard jog.

  • My X-axis on the Blacktoe cannot run above ~40 ipm. I've checked all connections,tensions, sprocket locks, etc. All is fine. Can the 425 OZ stepping motor be replaced with a bigger motor, or could a second 425 OZ stepper be added to increase torque?

    it is possible to install 2 motors on a single axis but you will require another driver and motor, but wire it directly to the same pins on your breakout board. Also the orientation of your motor since it is opposite side of the original so getting it to move accordingly to the original motor it will need to be orientated correctly. The slight shift could be the cause of the rod not being completely flat where the set screws are suppose to tighten the sprocket to the rod, so sanding it to a flatter surface might fix the shift in directions.
    Currently do not have a kit or schematic available.

  • IF WE ASSUME DESIRE TO PLACE THE RED LEAF 6' AWAY FROM TABLE, HOW MUCH CABLE IS NEEDED CONNECT MOTORS ON TABLE ITSELF?

    blackToe requires a minimum cable length of of 15 ft for X, 17 ft for Y and 18 ft for Z for the redLeaf to be positioned at midpoint along the long axis and under the table. Each axis would need have 6 feet extra (form the midpoint)

  • 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.

  • what parts would i need from you to convert my cnc plasma table into a laser cutter? price?

    First, you would need a laser tube, laser power supply, laser controller and a lens holder. You may need mirrors and mirror holders if you plan on orienting the laser tube in a direction other than directly towards the work surface.

    You can find these items and prices here: https://www.buildyourcnc.com/LaserComponents.aspx

    You will need to mount the laser tube and power supply. We recommend mounting the tube and power supply to the gantry, or directly to the axis that moves across the gantry for reduced power loss and to eliminate slight drift from mirror alignment error.

    The controller will need to be connected to your existing motor drivers. If you wish to still use your plasma table for plasma cutting work, you will need to have a switch and transistor circuit to switch which controller has precedence to control the drivers (having both controllers connected to the drivers, but having a TTL circuit using buffer/gates chips that is controlled by a single switch. We can assembly this circuit for you for a fee.

    If this is a machine that we did not manufacture, you will need to create the mounts for the laser tube. We can provide guidance for a fee if needed.

    Additional Information:
    Will my existing controller not work for controlling both? What would I need to make the laser cut when the table moves. The table has a thc and enable disable circuit. Also when will the mirror mounting head assembly be in stock again?

    Additional Information:
    I'm not familiar with the controller that you use for plasma cutting. The principle is probably the same. There is two main axes for movement and a trigger signal to start the plasma cutting. Not sure if your plasma table contains a z-axis that follows closely to the work surface to get the most efficient arcing. That function could be helpful, but not necessary for the laser.

    If your controller has a standard digital level trigger control, then that would be fine.

    Laser controller have the ability to create raster style engraving. If you don't need this functionality, then a laser controller may not be needed.

  • I'm new to CNC and just finish building my router.I need software for my post processor and not sure if your product is what I need?

    You will need a CNC software that will control your router cnc machine, and your design CAD/CAM software will need to know the CNC software you plan on using so the post processor in the CAM software can create the g-code for the CNC control software. So if you have for example, Mach 3 and our parallel breakout board, you can use the Mach 3 post processor in your design software.

  • I cannot turn the shaft of my stepper motor. It not even connected to a driver

    The motor is creating it's own EMF when you try to turn the shaft manually. When coils are connected (or not connected) to any circuit that is not powered can cause unpredictable results.

    The motor freezing from just turning it by hand with no connection is surely the wires touching each other. This is actually how we test if a motor is good or bad. If the motor freezes when two of the wires are touching, that means the motor is functioning properly since the magnets are causing current to flow through that coil opposing the magnet.
