Question #: 13525

Question: What is the bill of materials included in the build your own laser 2' x 4' 40 watt

Current Solution

The general bill of materials for the blackTooth 24"x20" laser system is as follows:

- The structural components (MDO and Plastic parts)
- The hardware to assemble all of the structural and mechanical parts
- Mechanical parts like v-groove bearings, bearings for shafts, shafts, pulleys, belts, etc.
- All of the motion electronics like motors, drivers, and laser controller
- Wire to connect all of the electronics
- All of the laser components including the laser tube, mirrors, mirror mounts, nozzle and lens
- Pneumatic components including the air pump and tubing
- Hydraulic components to cool the laser tube including a water pump and tubing

Other Possible Solutions to this Question

  • 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.

  • What materials can the Greenbull machine cut? What materials can the laser cut? Can the laser etch?

    The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



    BYCNC Response:
    Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

  • Hi im interested in your new 4 x 8' laser , what is the thickest mdf sheet it can cut through ?

    We have not specifically tested for this data point, but a general rule of thumb is that an 80W CO2 laser can cut wood up to about 1/2 inch. Actual results depend on a number of variables -- power level used, amount of air assist, focal length of lens, number of passes, cutting speed -- and each of those has its own tradeoffs. We are planning to do some of these tests in the near future and post the results, so stay tuned for more in depth information.

  • Can you explain exactly what is included in the green bull 4x package?

    There are two main choices with the greenBull 4x product: the kits of parts and the assembled.

    The assembled version comes complete with the gantry assembled including all of the wiring and electronics already connected, the spindle hoses and all of the cables and hoses running through cable carriers. You will need to construct the table of the machine. If you need the table to be included, consider the new greenBull version 2: https://buildyourcnc.com/item/cnc-machine-greenbullv2-milling-laser

    The kit comes with all of the items of the assembled version but does not come with the wires and cabling.

  • 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.

  • I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

    The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

    Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

  • is everything included in the 4axis cnc kit to build a cnc control box like wires,connectors,wiring diagrams ect?

    The electronics combos come with stepping motor drivers, stepping motors, breakout board (interface between the computer and the drivers) and power supply. The electronic combos do not include the cable and wires since the mounting configuration can differ from application to application.

    The wiring diagrams are located on the product page for each product. For instance, to determine the wiring for the motors, go to the specific motor that you purchase and the datasheet will be available which will include the wiring configuration. The breakout board product page will contain the wiring diagram for the remaining electronics. You can also use the electronics videos found here (https://buildyourcnc.com/CNCElectronicsandWiring.aspx) to understand the best process to connect all of the electronics.

  • What is the max thickness of material that the 80W laser can cut in plywood?

    An 80 watt laser can cut plywood up to 1/2 inch thick. Make sure to use a high pressure source of air to knock out all of the charring during the cutting process so the laser can work efficiently.

    Additional Information:
    I have a Chinese 80W laser. Just finished a cut test with 1/2" plywood. It cut through at 95% power 7-4mm/s with significant charring after two passes with no refocusing done between passes.

    Additional Information:
    That's great information. What is your PSI of the air assist on your laser? What focal lens distance do you have? And where did you place the focus of the lens (at the surface, or within the material)?
