Other Possible Solutions to this Question

  • 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 have a planetcnc USB controller to run my project and when I start the 240v router the USB connection shuts down.

    The USB controller will only work with the Planet-CNC software. This software is well made and will provide great functionality. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly.

    There are two main alternatives if you want to use the mach3 software:
    First, get a parallel port card and add it to your computer and get a parallel breakout board. If you have a laptop/notebook computer, this will not be possible.
    Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3.

    Additional Information:
    The planet cnc controller can be prone to electrical interference and has been known to cause such problems. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Alternatively you may need to sheild your limit switch, estop and or motor cabling. My pick is that a quality USB cable will fix it though, worked for me.

  • I have a "Based on planet-cnc's diy cnc usb controller", how I can connect a signal to turn on a mist?

    If you need to control mist, coolant or spindle using the USB Planet-cnc controller, you will need to connect that specific output terminal to an SSR (Solid State Relay). The solid state relay will act as a switch when the output signal is engaged.

    Additional Information:

    I did it, I activated the output signal in the planetcnc software but at the output there is no voltage

    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.

  • I have a "Based on planet-cnc's diy cnc usb controller", I activated the output signal (mist, coolant or spindle) in the planetcnc software but at the output there is no voltage, what can I do to turn on this elements?

    On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.

    Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.

    Additional Information:
    I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?

    Additional Information:
    There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.

    Additional Information:
    If you want to troubleshoot this yourself, take a very close look at the traces from the terminal and follow them to the tiny resistors, then to the legs of the chip. If you see any bad or bridged solder joints, then those will need to be re-touched. It will take a somewhat experienced soldering individual to accomplish this task and will require flux to make sure the solder joints are fully joined.

  • Have a CNC routher that uses the Porter Cable 78125 considering 2.2kw spindle and controller do you have any mounts and our recommenadtions?

    You are making the right choice. The overall cost benefit of a spindle over a router is worth the change. We used a router back in 2008-2012 and constantly replaced it due to the daily use, but we are still using the same spindle we began using back in 2012.

    We sell a mount that you can find here:
    https://www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-80mm-mount

    The mount fits standard 80mm spindles.

  • I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

    The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

    Additional Information:
    I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

    Additional Information:
    Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

  • I have the usb breakout board https://buildyourcnc.com/Item/electronicsAndMotors-electronic-component-USB-Controller-Breakout and need to run the A axis as a slave the software greys out the box how do I fix this?

    You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
    The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
    The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

  • Do you guys have any videos showing how to connect limit switches to a redleaf? If not, could you please make one? I looked at the diagrams on the limit switch page but I don't understand them.

    Connecting the limit switches on the redLeaf use the input pins on the parallel breakout board. Here is a link to the wiring diagram for that parallel breakout board.

    https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/

    The connection is simple. Just create a circuit from ground to the pin. When the pin is engaged, the circuit is closed (using normally open on the switch). Use mach3's autoset to automatically set the pin for the limit or home setting.

  • If I understand correctly, the greenBull kit comes with a spindle and laser. What else do I need to have a working machine. Obviously a table, do I also need the computer, software, wires, pump and plumbing, electronics, VFD, steppers and controllers?

    The greenBull kit (not the assembled) will need the table (the rails for the table is supplied), wires/cables for the stepper motors and stepper motor drivers, smaller gauge wires for digital wire connections (limit switches, drivers to control interface, etc), wires for the spindle connection to the VFD, tubing for water flow to and from the spindle, and a pump and reservoir (we are just about to introduce a small pump/reservoir/radiator/fan system for use with the spindle. The VFD/spindle, stepper motors/drivers and interface board are included.

  • How can I connect an inductive proximity sensor to the Mach3 USB controller?

    I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

    The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

  • On your diagram it says to connect the power to the VFD in port L1, L2 and PE. On the VFD I have there is no L1 or L2. Which ports do I connect my input power to? There is only a P+, P-, R, S, T, U, V, W, and PE. What do I do?

    On "our" VFDs, we advise that the R connect to black (live), T connect to white (neutral) and green to E or earth. We are not professional electricians, so we also recommend that you seek the advice of a professional electrician. Some VFDs are made to work on 3 phase power and this configuration may not work with these VFDs.
