  • where on your mk1 usb controller is the input port i can use for pause or estop comand thanks

    On our USB breakout boards, the pins available for any inputs (e-stop/limit switches).
    Are x++ - a-- (x++,x--,y,z,a(same)) in the settings menu you will have to specify the pin!

    Here is a good forum on Planet-CNC.com to help setting up Planet-CNC software:(http://www.planet-cnc.com/faq/machine_setup/)

  • My Spindle has 4 pins but only the U, V and W terminals at used for the Spindle. What about the 4th pin?

    The terminals of U, V and W from the VFD (Variable Frequency Drive) connects to the three coils (first three pins of the connector) of the spindle. The 4th pin in the spindle is typically not connected; however, bring a wire from the PE (Protective Earth or Earth Ground) from the VFD and connect it to one of the screws of the connector on the spindle. This will ground the body of the spindle.

  • the relay on the 57CNC card turns on and the VFD starts up but it won"t turn off. Relay #1 stays on all the time. Even the Estop won't turn it off. Relay #2 doesn't work all

    Turns out it was an electrical noise problem from the VFD. Troubleshooting showed me everything worked perfect even with the drive powered up but when the VFD started it would NOT stop from Mach3. I had run shielded cable and grounded it in the VFD but I had an intermediate break in the shield wire at my Master Control Relay (MCR) that is activated by an Estop on my control panel.

    This confirms the importance of shielded cable and making sure that the shield is contiguous.

    My guess is the wire(s) going to the dry contacts on the relay carried enough energy to fire the base of the transistor supplying coil voltage to relay #1. Or there might have just been enough induced voltage to the relay to fire the relay coil.
    I've fought similar VFD noise issues for 25 years and it still amazes me how pesky it can be. It's impossible to maintain any separation of signal and motor leads in the tiny space in the VFD.

  • your link to the tutorial for the PlanetUSB setup, "http://planet-cnc.com/faq/machine_setup/", doesn't work.
  • Does Mach3USB have a selection for motor tuning, if so, where, the selection in the config menu doesn't work

    The motor tuning for any controller under Mach3 is independent of the actual controller. It is actually a function of the steps per unit and setting the velocity which is units/minute and acceleration which is units/minute/minute.

    To adjust the velocity, acceleration and steps/unit, click on config -> motor tuning.

  • I have the 2.2 kW spindle and VFD for 110v, just wondering what amperage this draws, as my electricain buddy is telling me I need to put in a 20 amp breaker for this. I cant seem to find any amerpage draw on the INPUT label

    You can actually set a current limit in in the VFD using the programming process and the specifications in the manual that came with your VFD. You can expect the spindle at 220 Volts AC to draw (using the standard formula):

    For Volts, I will use 230 as the range is generally 220 to 240.

    Watts = Current * Volts

    Can also be written as:

    Current = Watts / Volts

    Current = 2.2kW (2200 watts) / 230 volts

    Current = 9.6 amps

  • I have your Mach3 usb interface board and am interested in the relay board to turn plasma torch on/off. I have a different relay board that doesn't work, it needs 0/5v from output pin to trigger and the usb board doesn't put out 5 volts. Does this relay board need 5v on output or will work fine with this usb controller?

    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.

  • Limit, E-stop and home switches: To set up the maximum number of switches set up I would need 2 BOB's, correct? How is this implimented and wired?

    The parallel breakout board allows for 4 input connections. Each input connection can have an unlimited number of switches, but if you need to separate the switch circuit for, say, all of the home switches, you can use another input pin. There is no need to add another breakout board to add more switches unless you need to use the input pins for totally unique conditions that may or may not be related to CNC functions.

    Customer response:
    To Clarify: I need to set up 3 home switches which can double for limits (that's 3 pins.). Another pin for a probe. That's 4 pins used. Now I need to set up the other limit and E-stop switches. No pins left, how do I do that? Can a ground pin be doubled up on?

    Plus, I have a SuperPID. Another pin?

    Additional answer:
    You can put all of your limit switches (including the E-stop which serves the same purpose as the limit switches) and home switches on a single pin. When homing, mach3 will move the axis it wants to home, hit the switch, pull away from the switch, then move the next axis and repeat the steps for the next two axes.

    The probe is on the 2nd pin. The SuperPID is on the 3rd pin and now you have another pin remaining.

    The GND terminal can be doubled up.

  • Is there a way to test input pins on your breakout board? I had pin 10 exclusivley configured to the estop switch, got a lot of false estops. I gave up on usung estopp and tride to configure pin 10 to a probe with what seemed to be false indicators of a closed circuit.

    To test input pins, we would usually recommend using a working limit switch or component. Which would allow you to view the current pin, for any problems or incorrect setting with the control software.

    When you wired the e-stop to pin 10, you did wire it in as normally open and also designated the correct pin to the e-stop in the control software?

    We also have noticed how sensitive limit switches and e-stops can be to noise around the system and through the wiring. We would recommend using a shielded cable and wiring/routing away from any other wires(power, communication, etc.).

  • How do I get Homing on Z to work with Plate and Ground using Buildyourcnc usb board all the entries for the sensor in planet-cnc are grayed out. I am using input z- and I purchased the software

    To home the z-axis using a plate:
    - Connect the end mill using a large clamping device like an alligator clip with a wire connected to GND.

    - Connect the plate (solder a wire to the plate) to one of the input pins.

    - You can use the autoset to setup that pin in Mach3 simply by touching the two together once connected to the pin and GND.

    Alternatively, the end mill can be connected to the pin and the plate connected to GND as long as there becomes a complete circuit when the end mill touches the plate.

    To setup homing for the Planet-CNC homing and limits, go to the Planet-CNC Machine setup page which explains the process step by step: http://www.planet-cnc.com/faq/machine_setup/

  • I'm trying to get the planet-cnc mist, coolant and spindle output to work. It's showing no voltage when I test

    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.

  • What length of wire do you recommend for the black toe (2'x4') between the spindle and VFD?

    The length of the cable from the VFD (Variable Frequency Drive) to the actual spindle should be about the same as the z-axis cable from the z-axis motor to the z-axis driver which is recommended at 11 feet. This is locating the VFD about at the midpoint of the machine.
