  • your link to the tutorial for the PlanetUSB setup, "http://planet-cnc.com/faq/machine_setup/", doesn't work.
  • How do I connect a Z-Axis touch plate to the Planet-CNC USB interface?

    "Semi automatic" measuring is possible.
    1. Place movable tool sensor (touch plate) on material.
    2. Click "Measure Offset Z". Tool will move down, touch sensor and move up.
    3. "Measure Offset Z" button is still down.
    4. Click "Offset - Current Z" - this will set offset Z
    5. Click "Measure Offset Z" again to release it and restore normal mode."

    The connections to the USB interface is as follows:
    - The spindle is connected to the gnd terminal (which is also connected to the end mill). Alternatively, you can connect the gnd directly to the end mill is access is permitted.
    - The touch plate (movable tool sensor) is connected to the Z-- terminal.

    What will happen: When the end mill (gnd) is in contact with the touch plate (Z--), there will be a connection from gnd to the Z-- triggering this Z-- action and the software will recognize the connection (like a button press, or a limit switch triggering).

  • 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.

  • Planet-CNC breakout board supports encoder inputs. I don't see this feature on your's. How does your board support threding, etc.?

    We need clarification on what you mean by threading: a parallel computer process, creating threads on a screw on a turning center, or threading a hole using a tap controlled by a CNC machine. If it's the latter two, you would rely on the stepping motors and dead reckoning (open loop system). Stepping motors will move exactly as instructed and have exact stop and positional accuracy so the threads would be constructed as intended; therefore, no need for encoders and feedback (closed loop system)

    Additional Information:
    What he is asking perhaps is that how would he be able to do rigid tapping without encoder input? Alternatively, he may need a servo drive for the spindle. Which board supports rotary encoder input? I am looking for boards myself.

  • I purchased the USB BOB and the link for the Planet-cnc software is broke. Will I need to purchase a license for the software as well?

    Here is the new link to the Planet CNC software download page: http://planet-cnc.com/software/

    You can try the software as a demo however you will have limited g-code lines you can run. I believe it was around 500, so you can create small items with the demo.
    To fully unlock the Planet-CNC software you will need to purchase the license.

  • Hello what is the thread size of the water cooling fittings on the 2.2kw spindle? I am wondering if I can replace the fittings with standard pc liquid cooling fittings, which are G1/4".

    They do have a similar looking thread as the G1/4”, but I will confirm in the morning. We use the G1/4” on the pump and radiator so it will be easy to determine this fit when I get into the office.

    Additional Information:
    Another FAQ says it is an M8, but I will confirm.

    Additional Information:
    These are M8x1 thread. I was able to find M8x1 3/8 barb fittings on Ebay. I plan to drill and tap my spindle to G1/4 though.

  • 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

  • I AM USING USB BREAKOUT BOARD WITH PLANET-CNC SOFTWARE. WHEN ENABLE JOGGING KEYBOARD X AXIS STARTS TO MOVE BY ITSELF (WHETHER CONNECTED OF NOT). PRESS STOP - IT STOPS FOR A MOMENT AND THEN AGAIN. WHAT COULD THAT BE? TRIED REINSTALL SOFTWARE DID NOT HELP.

    It seems to be getting some kind of interference or a short within the wiring or communication, try jogging the motors in the software without anything wired to the board. Then add one motor at a time to see if there is a short within your wiring or a faulty driver/motor.
    If the USB breakout board continues to move the x-axis with no motors or driver wired to it, please email customerservice@buildyourcnc.com for a replacement or further troubleshooting.

  • What settings does I use for controlling the spindle in StepCon/Linuxcnc?

    LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

    The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

    Additional Information:
    After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

    Additional Information:
    To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

    Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

    In the VFD parameters:
    PD001: 2 to accept RS485 commands
    PD002: 2 to accept frequency comands
    PD163: 1 to RS485 slave address:1
    PD164: 1 RS485 baud rate 9600
    PD165: 3 8bit, no parity, 1 stop bit

    Make sure LinuxCNC is also set accordingly:

    The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

    In the options step of the stepconf wizard:
    - Check the Include Halui user interface component.
    - Check the Include custom PyVCP GUI panel.
    - Check Spindle speed display

    You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
    loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
    net spindle-cmd-rpm-abs => vfd.speed-command
    net spindle-cw motion.spindle-forward => vfd.spindle-forward
    net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
    net on motion.spindle-on => vfd.spindle-on

    The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

    Under the custom_postgui.hal file, change this line:

    from: sets spindle-at-speed true
    to: net spindle-at-speed => cfd.spindle_at_speed

    and add the line:

    setp vfd.enable 1

    When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

  • What is the benefit to using a spindle over a standard router?

    This solution will refer to the water cooled spindles that we sell. Generally, routers are air cooled which push air downwards through the router to cool the router motor. This has an undesirable effect for CNC machines that will blow the dust and chips into the air. The water cooled spindle will not blow since it uses water to cool the spindle motor. This allows the chips and dust to be confined within the dust shoe and get removed by the vacuum. Additionally, standard routers have a sound level that far exceeds that of the spindle.

    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.
