Question #: 14866

Question: [4' x 8' Vertical Laser XL - Laser Cutter/Engraver] How does your piece stay In place - so I cut a circle out - does it fall out?

Current Solution

The workpiece (the item being cut or engraved by the laser) in the laser is not perfectly vertical. There is an angle to the bed, and a ledge at the bottom that the workpiece will set against, so the workpiece will stay in place. Depending on the size, weight, and rigidity of the workpiece, you may need to adhere the workpiece to the bed using various methods. For example, if the workpiece is a piece of leather, you will need to adhere the workpiece to the bed, or to another item that can be placed into the machine. More rigid items can simply be placed into the laser and the operation of cutting and engraving can start without adhering the workpiece to the bed of the machine.

Since lasers (as opposed to a CNC with a spindle that creates a physical cutting action) there is no force on the workpiece. Only the lasing light will be hitting the workpiece. The kerf of the cut from a laser is small enough that parts cut out of the workpiece will stay in place. If you feel that there are pieces that may fall out of the machine while cutting, you can use various methods of adhering those sections to the bed of the machine.

  • How do I secure the non-motor end of the lead screw for my 'Book' machine build? Does it just sit inside the bearing or do i use a nut to lock it in place? I did not see any instructions for this in the book.

    Use a clamping collar (if you are using an ACME lead screw) or a couple of 1/2 nuts (if using an allthread) against the bearing to keep the bearing in place and make sure there is no axial play.

  • I am interested in getting your 40W laser system. How difficult will it be to increase the size to 48" x 48"?

    The blackTooth machine, as it is designed cannot be modified easily as the box within which it is contained also serve as its structure. We are currently designing a special mount for the greenBull (for the 40 watt tube) which will provide 5'x10' or 6'x12' work area and the machine is far less expensive than comparable 4'x8' laser systems. We are also developing a 4'x8' 80 watt system where the tube is in the horizontal orientation. More information can be found in the R&D section.

  • 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 CAUSES RINGING IN YOUR EAR AND HOW CAN YOU STOP IT?

    Tinnitus . Learn to love it. No really you should see a doctor. Make sure. White noise will help you sleep when it gets loud.

    Additional Information:
    I learned, too late, that if a sudden loud event causes tinnitus, see an audiologist IMMEDIATELY. They can do something about it if addressed within a day or so.

    Wear hearing protection...always. Loud noises trigger my tinnitus, and headphones and ear plugs (when out & about or at the movies, subway, etc) help tremendously. Mine are rated 33dB.

  • My cnc electronics does not turn on with my spindle. How can I fix it?

    Yes, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

    Some of the types of CNC electronics we will consider.

    - We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

    - We will repair or retrofit used CNC electronics.

    - Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

    The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.

    Here is an example of CNC electronics that we worked on for a customer:



    This is the type of response that you can expect to receive after the CNC electronics are repaired or retrofitted to work under Mach3, Mach4 or LinuxCNC. You can see the entire work, which also shows the time involved. We also show what we were able to accomplish at the beginning of the video.

  • Will your 2.5 KW spindle work with my Hitachi WJ200-022SF VFD and does it have a thermal couple temp output?

    From reading on the Hitachi WJ200-022SF VFD, it seems as it will work just fine with this VFD. However since we have not tried this cross match, I would carefully take each connection and setting into great consideration and detail on both the Hitachi recommendations for setup, as well as our spindles recommended setup.
    Our spindles do not have a thermal couple temperature output.

  • 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.

  • MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE MACHINE?

    If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

  • 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.

  • So after I install the stepper motors, how does the system know what’s the start position ? I’m modifying a lathe.

    If you are using a control program, like Mach3, then you will move (jog) the axis to the location that you want to set as your start position and "zero" that axis. Make sure that the axis moves in the positive direction where you would expect. If this is not the case, you will need to reverse that axis according to the instruction with your control program.
