Question #: 1038

Question: Is there a manual or some documentation of how a binary value in the printer port translates to position on each motor?

Current Solution

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

  • 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.

  • Hello! Question about the x motor on the vlxl. There is no black lead. Is the yellow in its position? Also, I really just want to double check that this wiring diagram is solid. About to finish the wiring. Juan told me to use the 36V for the tube and 24 for the drivers. Correct?

    The stepper motor on the X axis on the VLXL is this motor here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-nema34-651ozin

    There is no black lead on that motor and the connection diagram can be found here:
    https://www.buildyourcnc.com/Documents/PN.SM86HT80-5504B-U(inhouse%20PN.85BYGH450A-47-80)%20(1).pdf

    Red - A+
    Green - A-
    Yellow - B+
    Blue - B-

    The wiring diagram on the instructions for the Vertical Laser XL is meant as a general guide for all laser systems. The motor specific to the axis should be checked against the datasheet to insure proper wiring.

    The 24V power supply should be connected to the laser controller. The 36V power supply should be connected to the drivers to power the motion electronics.

    Additional Information:
    My fault. Must have had that backwards. I'm sure he told me the right way.

    Additional Information:
    Not a problem. The laser controller has two terminals labeled for the 24V connection.

    The 36V power supply works really well for stepper motor drivers as the voltage/current on this power supply allows for best stepper motor performance with this laser application.

  • Am I supposed to drill a hole in the back of the gantry to access the wires for the motor?? There does not seem to be a way to access the wires for the x axis motor once the gantry back is installed.

    The installation of the motor inside the gantry is mounted and wired before installation of the back plate of the gantry. For Example, our blackFoot machine seen in steps(124/139), you can see that the gantry and and z axis is complete finished before back plate is placed.

  • 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.

  • WHAT EFFECTS OF CELL PHONES WILL THERE BE ON YOUNGER PEOPLE OPPOSED TO OLDER PEOPLE? THE AGE OR STATE DEVELOPMENT EFFECT DANGERS A PHONE?

    Physical size of the subject affects the fraction of the total radiofrequency energy that is absorbed in the body. To account for this known effect, the maximum permissible exposure standards for radiofrequency energy were set for the worst-case condition, that is assuming the body size for maximal absorption at a given frequency. Thus the maximum permissible exposure standards are fully protective for bodies of different sizes. For more detailed information, see the answers and the cited references to questions 79, 109, 694, and 893 under the Nonionizing Radiation section of the Health Physics Society Ask The Expert Web page.

  • 3d printer filament is not feeding. It is heating and will melt and feed some but not consistently. Any tips on adjusting the set screw to get a good feed? I'm using PLA with the MK7 stepstruder being sold on the site.

    This may be less of an issue of the grasp that the feeder has on the filament and more an issue of the heat getting to the plastic at the hot end, or having enough heat at the hot end. Try increasing the temperature and try again. If that doesn't work, make sure you are insulating the hot end sufficiently to keep the hot end hot enough to keep the plastic melted.

  • The extruder motor on my WhiteAnt is running very hot and causing the filament to lose integrity near the drive gear causing stripping. How can I adjust the motor controller to reduce current draw or are there other sugesstions to help it run cooler? the fan runs full time.

    To answer my own question, I just tweaked the trimmer down for the extruder motor until it stopped extruding during a print, then raised it back up one "tweak" until it started extruding again. Since then I have been able to run continuously without overheating the motor. Sorry for the inexactness of my measurements. Basically, the trimmer started at 12:00. I turned it counter-clockwise to about 7:30 and things seem pretty dialed in.

  • hey, where can i see the steps how can i control 3 or 4 step motor? can i use the Axis Electronics Combo? or i need to connect controller?

    Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
    The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
    Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

  • 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.

  • As I am building my 20" x 24" laser engraver cutter, I notice that there is no parallel port on the onboard computer and I have the parallel breakout board any answers?

    Most motherboard do contain parallel ports, but the port connector may not be at the back (in the section where external connectors will be connected). Instead, the motherboard may contain an LPT ribbon connector on the actual face of the motherboard (usually along one of the edges). You will need a ribbon connector to a DB25 female connector.

    If your motherboard does not contain an LPT header on the motherboard, you can purchase a parallel printer adapter that plugs into one of the PCI slots. The price of the adapter is very inexpensive and sometimes is actually less costly than the actual ribbon connector.

  • how can I convert the whiteAnt from the 3D printer mode to the CNC milling mode?

    To convert the whiteAnt to a CNC machine, you will want to lower the upper structure to the lowest position to create the most rigidity overall. You will see that there are many holes below the sides of the upper structure that are evenly spaced. This is so you can adjust this lower. You will also want to fasten the lower sides to a substrate (piece of wood, or something) with l-brackets or something that has a bit of adjustment capability. This will keep the sides more rigid as well. Use a Dremel for the spindle. If you want to use a another spindle, let me know and we can product a mount for that spindle since the Dremel has poor runout (TIR). This is important if you are wanting really precise milling.

  • the bluechik - IS there a 3D Touch Scanning to scan in present made items ?

    Yes, you can use a touch probe with our machines as it is really independent of the machine structure, mechanical components and motion electronics, for the most part. We don't currently sell touch probes, however, but standard touch probes for CNC machines will work fine.
