Question #: 13643

Question: my servos only spin in one direction! and not only that, but when they do spin it is super jittery and inconsistent, it will spina small amount and juat clcik,

Current Solution

This sounds like a wiring issue where you have the incorrect wires going to the driver in the wrong locations (i.e. A+ A- B+ and B-). Check the wiring diagram for the motor and verify that it is wired correctly.

  • ON THE BOB...EVERYTHING TESTS OK BOB EXCEPT X-DIRECTION OUT. IT'S VOLTAGE IS SLIGHTLY DIFFERENT THAN Y AND Z (5.00 INSTEAD OF 5.03. TESTED X DIRECTION ALL THREE DRIVERS. IN EACH CASE THERE GOING INTO DRIVER BUT NOT OUT IT.

    The electronics can be tricky sometimes, especially if more than one change is made for a test. You can move the x-dir wire to another pin and set it in the software configuration. If it works, then only that pin is bad.

  • ABSOLUTELY NOTHING WORKS. I HAVE ALL STRUCTURE AND MECHICAL PARTS OF THE BLACKTOOTH CUTTER DONE. HOWEVER WHEN WIRE UP STEPPER MOTOR TO DRIVER. THAT MACH 3 USB CONTROLLER BOARD, TRY JOG MOTOR, WORKS! PREVIOSULY HAD PLANET CNC BREAKOUT HOWRVER, ONLY MOVED MOTORS IN ONE DIRECTION COULDNT CHANGE IT. ANY HELP WOULD BE APRECIATED
  • Provided they will fit and I install a ventilation/cooling fan, is there any reason why I should NOT mount the electronics (breakout board, stepper drivers and power supply) inside the gantry box in my BlackToe 2x4?

    First, see Jack's build: https://www.buildyourcnc.com/JackRehak.aspx

    The difference between mounting the electronics in the gantry is that the connection from the computer (signal level) is long. The alternative, where the electronics is near the computer, the motor cables are long (to reach from the drivers to the motors).

    Mounting the breakout board, drivers and power supply within the gantry will cause you to have a long signal connection from the computer to the breakout board. That is fine as long as the cable is long enough, possibly shielded, and can carry the signal at long cable lengths. Make sure to have the cable well away from the motor cables as these will cause quite a bit of interference.

  • I HAVE ONE OF YOUR SMALLER STEPPER MOTORS RUNNING MY X AXIS BRIDGE CRANE AND IF IT IS MOVED TO FAST THE MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

  • 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?

    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.

  • I AM HAVING TROUBLES FINDING THE PD PROGRAM, HAVE BUT IT DOESN'T SHOW EVERYTHING NEED TO PROGRAM MY VFD. ANY HELP WILL BE APPRECIATED...

    When you power up your VFD, you can go into the programming mode by pressing the program button. You can press the up and down arrows to move through the parameters. Press the set button to go into the parameter to see the value of that parameter. If you want to make changes to that parameter, change the value with the up and down arrows until the desired value is shown, and press the set button to accept the changes.

  • IT POSSIBLE TO BUY THE CAD FILES FOR BLACK FOOT MACHINE, MECHANICAL PARTS AND ELECTRONICS BUT NOT WOODEN PARTS, SAVE SHIPPING COSTS? IN THAT CASE I WOULD INSTRUCT SOMEONE MILL ME.

    The files and hardware option for our machines has been removed from the site due to the following reasons:
    Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
    The abuse of these files over the internet.
    Ultimately may reduce the sales of machines keeping us in business.
    Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.

    Additional Information:
    NO, is not possible, I can help with the shipping cost

  • 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 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.

  • IT MORE DANGEROUS STAY FOR ONE HOUR AT A TEN-METER DISTANCE FROM CELLULAR ANTENNA OR TALK INTO PHONE THE SAME AMOUNT OF TIME?

    Cellular phones are designed to be safe for both the user and anyone standing nearby. Cellular phones are actually small radios that transmit signals to and from base-station antennas located on towers or buildings in the nearby neighborhood. Cellular phones use low-power radio signals, even weaker than CB, police, or fire radios.

    The American National Standards Institute (ANSI) sets safety standards for human exposure to radiofrequency (RF) electromagnetic energy in the United States. Government agencies such as the Federal Communications Commission (FCC), the Occupational Safety and Health Administration (OSHA), and many states recognize and accept the ANSI RF safety standard. Also, the United States standard for RF energy is comparable to those set in other countries.

    Cellular phones and cellular-phone base stations have been shown to meet these RF safety standards. Safety standards for RF energy are threshold standards. Threshold standards define the level of RF energy above which there may be health or safety hazards and below which there have been no reported harmful effects. Unlike ionizing radiation, which many people believe to act cumulatively even at small exposure levels, RF energy at low levels is not considered a cumulative hazard. Therefore the consensus of scientific experts in this area is that RF exposure from cellular phones, meeting the threshold levels set in safety standards, is safe for all.

    The specific answer to the question is that cellular phone technology is safe for all. There is no danger posed by either handheld phone units or by base-station antennas. In both cases, the radio signals transmitted from the antennas are required to meet the ANSI safety standard for RF safety as embodied in FCC regulations governing this technology. For more information:

    The FCC has recently revised and reissued its Bulletin 56 on Questions and Answers about Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields.

    OSHA provides information and links to more sites on RF safety at its Web page, Radiofrequency/Microwave Radiation.

  • CAN YOU GIVE ME SOME HELP OR POINT IN THE RIGHT DIRECTION TO INCORPORATE MK 7 EXTRUDER WITH BOOK PLANS FOR 3D PRINTER?

    Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.

  • 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.

  • 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.

  • 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.
