Question #: 625

Question: THE LEAD SCREW IS VERY HARD TO TURN. BACKLASH BUSHING SEEMS BE TOO TIGHT AND BINDING ON SCREW. DO IT NEED LUBRICATION OR DID DAMAGE NUT WHEN INSERTING SCREW?

Current Solution

Yes, you can use lubrication, like 3-in-1 oil to make it a bit easier. You will need to run it up and down to break it in.

  • BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?
  • My Z-axis seems to be reversed on a fully assembled machine... I've tried reversing it in the config settings on Mach 3, but to no avail. What do I need to do? IS this a wiring issue that was not done correctly at the factory?

    If your Z axis is moving in the opposite direction, go into Mach3, click on config, ports & pins, then click on the motor outputs tab. You will see the axes labeled on the left and the parameters labeled on the top of this dialog box. Toggle the dir low active for the z-axis.

    Additional Information:
    What if I'm having the same issue on a different axis?

    Additional Information:
    You can follow the same procedure as with the z-axis. When you get to the motors outputs tab, toggle the dir low active checkbox for the axis that you would like to change.

    If you are using another control program, let me know and I will add the recommended action here.

  • DO NEED TO GET THE BIG PLANING BIT OR SURFACING AND GO OVER SPOIL BOARD MAKE SURE THAT IT IS PERFECTLY LEVEL IN RELATION ROUTER?

    Yes, that is highly recommended for all the reasons you can imagine. Say you were doing engraving, not surfacing the spoilboard will either exhibit some areas that have no engraving at all, or areas that have engraving that is too deep. If you are cutting completely through the material, then one end may be cut all the way through but the other end will not have a complete cut, or produce onion skinning on the bottom of the workpiece.

  • 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.

  • HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

    BYCNC response:

    Milling aluminum is no problem with our machines.

    Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

    The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

  • I have the 2.2KW VFD. I would like to have it controlled through software. What are the Mode parameters that need to be changed that will allow FWD/ REV, START/STOP and RPM control?

    What controller are you using to control the cnc machine (Mach3 usb, parallel breakout board, etc.)?

    The spindle VFD has an input for 0-10 volts to control the speed and can be used with the MAch3 USB or the Pokeys57CNC board. There are also other terminals in the VFD to control the forwared/reverse and start and stop. Mach3 has parameters to control these output and you need to specify which pins are used for these.

    You can also use the TX/RX RS-485 connection on the VFD to have total control using an FTDI USB to serial connector board to connect the computer directly to the VFD.

  • LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.

    BYCNC Response:
    This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

    User Response:
    I am using the cnc planet software for your USB board. Are the limit configurations in this software?

    BYCNC Response:
    Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

  • THE CNC MACHINE IS UNSAFE WITH EXPOSED SPROCKETS THAT CAN DAMAGE FINGERS AND HAVE CLOTHING CAUGHT IN IT.

    These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

    With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

  • 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.

  • I AM PUTTING TOGETHER THE BLACKFOOT AND USING A PORTER CABLE ROUTER. CONFUSED ON HOW TO RELAY ROUTETR WITH USB BOARD. IS THERE ANOTHER SWITCH THAT GOES BETWEEN BOARD ROUTER SO PLANET CNC CAN TURN PERHAPS VACUUM OFF?

    We are currently working on a relay board that will connect to USB breakout board, and the router/spindle for both the on/off function. Unfortunately we still do not have it completed or ready to be placed on our website, but it is in the final stages of testing. Please check back regularly for updated stock!

    Here is a link to a tutorial for a DIY relay circuit:



    There is no vacuum control on the Planet-CNC program, however you could use the same concept of the router/spindle on/off using the relay circuit. Although you will have to use either the flood or mist function for the vacuum.

  • I BOUGHT YOUR BOOK AND WAS HOPEING IT HAD PLANS OR DIMENTIONS ON HOW TO BUILD A CNC HOLD 4X8 SHEET OF PLY. WILL THE IN SCALE UP?

    BYCNC Response:
    The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

    User Response:
    I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

    BYCNC Response:
    It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

  • AM NOT SURE HOW TO SET THE Z AXIS TURN ON/OFF LASER WHEN CREATE CODE. KNOW THAT ITS TYPICALLY Z-AXIS MOVEMENT DOES THIS - BUT YOU DONT SHOW ANYTHING HOOKED UP IN PLACE OF AXIS.

    When the z axis is going down, the laser turns on. When the z axis is going up, it turns off. The z axis directions is only a signal that is either 5v or 0v. That determines the direction. In vectric, you will need to set your machining operations with a very very small depth so the time it takes to get to its final depth is a very short time.

  • DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?

    The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

  • WHAT IS THE MOST EASY WAY TO HOOK UP MILL IN THAT AUTOMATICALLY STARTS WHEN CYCLE STARTS, AND STOPS GCODE THROUGH?

    Does your breakout board (interface) have a relay? If so, you can connect one of the router/spindle's ac lines through the relay. The M3, M4 and M5 codes are used to control the router/spindle. Typically, the M codes are automatically added to the g-code regardless if you configure this in your CAM software. If you have the breakout board from buildyourcnc, you can go to the product page for the breakout board and the relay connection diagram and narrative is in the instructions on that page.
