  • Would any of your CNC laser machines be appropriate for welding of thermoplastic materials?

    That is a good question. We have not tried to weld thermoplastics using our CO2 Lasers. It is possible since the laser outputs a heat source and at the right intensity and speed, the thermoplastic can be heated and melted rather than instantaneously vaporized and off gassed. I have done research to see if CO2 laser can weld thermoplastics with positive results.

    Our CO2 lasers are typical of other laser cutters on the market, so if their literature, or examples you have found, successfully weld thermoplastics, then ours will probably be able to as well.

    In some cutting test with different speeds and intensities, the kerf has welded back together; however, this was caused by an unintentional process rather than an intentional one.

  • Would your greenBull 6X CNC machine be suitable for cutting 2024T3 aircraft aluminium? Working on a kitlpane project and I need this capability.

    the greenBull can handle cutting aluminum as long as the correct bit (end mill) is used and the bit is cooled frequently to prevent chips from melting and causing damage to the bit or warping the material.

  • I own a custom rug shop where we design a fabricate custom floors of many types, Have you performed any type of testing using your 40 watt and or 80 watt laser for the cutting of thse textiles.

    Yes, we have cut many fabrics with the laser. Or CO2 lasers can generally cut fabrics and textiles without a problem. What types of textiles (materials) do you need to use with the laser machine? Is there a layering of materials?

    Additional Information:
    We would cut multiple heights of different carpets and even hard surfaces such as Vinyl composition tile, Luxury vinyl tile,etc. and I'm wanting to explore etching into plain color carpets using the laser.
    I'm contemplating your 5' x 12' machine with the laser/spindle combo.
    Is it possible to make a site visit to your location and see the capabilities of the equipment ?

    Additional Information:
    Carpets are not a problem as long as there are no materials in the carpet or in the carpet binding layers that will off-gas toxic fumes. Check the manufacturer's materials of all of the parts of the carpet.

    The vinyl should not be a problem, just make sure there is no material mixed within the composite that will off-gas harmful fumes such as chloride. The chloride will mix with the hydrogen in the air and form HCL (hydrochloric acid) which can be harmful if inhaled, but can also affect some of the metallic parts in the machine.

    We have cut vinyl with the laser with great results.

  • For cutting with the BlackTooth, what is the best type of clear plastic/acrylic to use, and can you recommend a source?

    The blackTooth will cut acrylic very easily. The type of acrylic (cast or extruded) is not important since the acrylic itself has 100% absorption with CO2 lasers. Any plastic retailer, even the home improvements stores will have sheets of acrylic.

    Avoid using plastics that will off-gas toxic and corrosive fumes. One example is PVC which is Polyvinyl Chloride. The burning of that material will exhaust chloride into the air and combine with the hydrogen in the air causing a chemical reaction yielding hydrochloric acid which is corrosive and highly toxic to humans.

    Always read the MSDS (Material Safety Data Sheet) for any material that you intend to burn with the CO2 laser.

  • Can any of your CNC kits be adapted to work with a manual wood lathe?

    It's best to design a machine specifically for a lathe rather than adapting an existing machine kit to an existing lathe. If you are interested in us designing a machine like this, let us know.

  • Where is the best place to see projects made with BuildYourCNC CNCs? I would like to get an idea of carving capabilities and cutting Baltic Birch plywood. Thanks.

    You can always come to our offices in Katy TX. If that is not an option, we can do cut in our shop and record video for you. Specify what you would like to cut and we can consider doing this for you.

    Thanks. I've reviewed the gallery and think my question comes down to this- Can I do hardwood carving like Mike M.'s guitar display cases and cut 3/4 inch baltic birch plywood with the same machine?

    Absolutely, the cutting and machining is more a function of how the machining operations are created and specified. Baltic birch is not a tough material and you will be able to cut very aggressively with any of our machine kits.

  • Is the Greenlean capable of cutting soft metals like aluminum or brass? Thanks

    Yes, the greenLean can cut metals such as aluminum and brass. The gantry and Y carriage was designed to be rigid enough to handle these types of metals. The typical metal cutting techniques should be used, such as high feedrates to reduce heat buildup at the end mill, or the use of cutting fluids or cold air used at the end mill as is necessary with most machines that cut similar metals. This is necessary since the aluminum has a rather low melting point and can clog the end mill.

    Additional Information:
    All of our machines are capable of cutting many metals, including steel and aluminum as long as the proper CNC machining operations are used like light fast passes, and if desired, using air cooling for better performance.

    Here is a video of one of our customer demonstrating aluminum cutting using air to cool the end mill.

  • How many feet of wire would you typically use to wire 6 limit switches on a 5x machine? (using your suggested location for said switches)

    Let me check.

    Additional Information:
    We suggest wiring the X and Y axes. We haven't seen the need for wiring the Z axis, but that is totally up to the CNC user as their application may require this use.

    I measured 13 feet of cable for the X and Y limit switch connections on the greenBull 5X gantry (2 limit switches on one gantry side for X limits and 2 limit switches on the gantry front extremes for Y axis limits). You will need to estimate how much more cable you will need from the gantry to the control box that you are using. I generally estimate the extra to be measured from the end of travel on the x-axis to the middle of the x-axis travel and then where you would position the control box from there.

  • I live in North Houston by Lake Conroe, Anyone around here have a 4x8 or larger machine that would not mind doing some simple cutting for me for a project?
  • Can your cnc's get within 1/10th of a human hair in accuracy while cutting?

    Dealing with a larger offset when cutting a larger object, try calibrating your machine accordingly (

    ) now you will have to do the last couple of steps a few times to get your machine as accurate as possible.
    Also if this does not correct your issue, try looking at the tightness of your x/y/z - axis chain, bearings, and also your sprocket/rod, the chain must be viewed as a bicycle chain if too tight it might snap when the machine moves but if to loose then it will be off. The rod is not totally flat where the set screws are suppose to hold down the rod, so sanding it to a flatter surface section might fix the offset.

  • What would be your recommendation for "power supply 2 (24vdc)" connecting to USB motion card?

    A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

    If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

    The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

  • How would you recommend cutting glass with a GreenBull?

    It depends on the type of cut you're trying to make and the type of glass. In general, straight cuts can be made by scoring the glass using a type of engraving bit, such as these:
    http://www.widgetworksunlimited.com/CNC_Specialty_Bits_s/33.htm.

    Complex curves and thicker glass is usually tackled with a diamond burr endmill and a specialized jig. Here is a nicely done you tube video giving an idea of how that works.

  • What type of alignment screw is used in the mirrors for the Black-tooth. Diameter/threads would be cool. a PN would be fantastic. thanks!

    The only screws that do not seem to be proprietary that may be able to be replaced are:

    There are M4 X 13mm screws in the Laser Head Mirror ad Lens Holder Nozzle assembly

    and

    There are M3 X 8mm screws in the Mirror Holder/Mount for 20mm Mirror

    The rest of the screws seem to be a very fine threaded metric based screw with a thumb screw for position locking.

  • what do you mean by Kits , are they complete machines ready for use or prototypes to be followed?

    Our kits include all of the parts needed to put a whole working machine together. However, understand that the kits are quite advanced and require a good level of mechanical competence to be completed correctly. We offer assembled machines for those that can't assemble these machines due to their complexity and need for fastening the overall components in a way that there is good smooth and tight motion, minimizing backlash to the fullest.

    We do have a few kits that you need to supply the table which include the greenBull 4x,5x and 6x, and the blackFoot. The tables would be far to large and heavy to ship. Our greenBull Kit is our best selling machine. All of the other machines are all inclusive.

    Additional Information:
    We do sell the parts to convert your CNC milling machine to a laser, but you will need to develop the mounts that will hold all of the laser parts to the machine, if the machine was design and built by you.

    We can offer guidance for this conversion.
