Question #: 13748

Question: The spindle drops on our greenBull when power is turned off. How do we stop this?

Current Solution

When you say the spindle drops, are you referring to the z-axis assembly that contains the spindle? If so, did you replace the lead screw and anti-backlash nut with a ball screw? Ball screws have extremely little friction and will cause an assembly under gravity to move down. If not, your lead screw and anti-backlash nut friction is extremely small, which is surprising and I have never seen this before. I would be interested in seeing a picture of the assembly. Please send a picture to techsupport@buildyourcnc.com so I can investigate this issue further.

Additional Information:
We haven't replaced or disassembled anything on the z-axis. I will try to get some photos sent to you. Are there any adjustments or recommendations for PM of the z-axis assembly?

Additional Information:
Can you tell me what PM means?

  • DOES THE SPINDLE RUN ON A 50HZ POWER SOURCE?

    The spindle inverter (VFD) will run on a 220V (or between 170V-250V) power source with either 50Hz or 60Hz.

  • I HAVE THE REDFLY SYSTEM AND A 2.2KW SPINDLE - 110V HOW DO CONNECT SPINDAL?

    It is not necessary to connect the spindle VFD (Variable Frequency Drive also called an Inverter) to the computer or CNC motion electronics. The VFD can be controlled independently using the control panel on the VFD. The control panel has the ability to control all aspects of the spindle including Speed, Torque, limits, etc. However, you can connect the VFD to the computer so the CNC control program can control the spindle during the CNC Machine operation. You will need to connect the VFD to the computer via a serial conection (in this case, it is the RS-485 protocol).

    The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection.

    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.

  • I JUST RECEIVED A REPLACEMENT SPINDLE (2.2KW 220V). HOWEVER, WHEN ATTEMPTED IT USE THE NEW SPINDLE, WOULD ONLY REACH 1500 RPM. IS THERE SOMETHING NEED TO CHANGE ON CONTROLLER?

    VFD settings........
    1) To program the VFD, wire it up, plug it in. It takes several seconds to come to life.

    2) Push the PRGM button to enter programing mode.

    3 )Push the SET button. The display will read PD000.

    4) If you push the SET button again, it will display the present setting of PD000.

    5 )By pushing the up or down arrows, you can change the setting to whatever it needs to be. (This is just an example. PD000 needs no changes)

    6)Push the SET button again to lock in the setting of PD000 and advance to the next number, in this case, PD001.

    7) Push the SET button and it will display the present setting of PD001. Again, use the up and down arrows as necessary to set PD001, then push SET again to lock it in.

    Note: You can also scroll through the PD numbers with the up and down arrows.

    8) make all settings this way.

    9) by pushing the SET button you can scroll through the settings. First push of SET moves to the next number, second push displays it's setting, third push moves to the next PD number.

    Note- If you take too long, it will leave the programing mode on it's own. If it does, just push PRGM again to return to programing mode. Then press SET and continue what you were doing.

    10) Start with PD013. Set it to 1, which returns the settings to the factory settings.

    11) Then set PD005 to 400, PD004 to 400, and PD003 to 400 IN THAT ORDER.

    12) Then set the following: PD041=8, PD144=3000

    13) Set PD209=50

    That's it for the programing. You should get 24000RPM when you push RUN.

  • IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

    I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

  • HOW MUCH RADIATION GIVEN OFF BY A CELL PHONE AND THERE ANY WAY TO STOP THE FROM BEING ABSORBED INTO YOURSELF?

    Portable cell phones emit about 0.6 watts of radiofrequency energy, limited primarily by the power of the battery. As with any radiofrequency transmitter, there will be some amount of absorption in the human body; the amount depends on how close you are to the antenna. The Federal Communications Commission (FCC) limits the amount of radiofrequency energy which cell phones can deposit in the body to levels at which no health effects are to be expected. See an article on Cell Phone Safety on this website for more information.

  • WHY DO PEOPLE RECEIVED INFLUENZA VACCINE LAST YEAR STILL NEED TO GET VACCINATED THIS WHEN THE VIRUSES HAVEN'T CHANGED?

    Although the strains may sometimes be the same as in the previous year's vaccine, you should NOT use the previous season's vaccine you might still have in your refrigerator. Influenza vaccine distributed in the northern hemisphere expires on June 30 after each season; expired vaccine should NEVER be administered. Secondly, antibody titers that persons might have achieved from the previous year's vaccination will have waned and need to be boosted with a dose of the current year's vaccine.

  • WHAT MATERIALS CAN THE GREENBULL MACHINE CUT? LASER ETCH?

    The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



    BYCNC Response:
    Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

  • WHICH MACHINE SHOULD I BUY, THE GREENBULL OR BLACKFOOT?

    The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

    Previous Solution:
    The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

    The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)
