Question #: 14056

Question: What metal sheets can I cut with the 80W laser? What thickness, alumium, steel? What about the 100 or 130W upgrades?

Current Solution

Cutting metals with a CO2 laser is nearly impossible with just the laser by itself, no matter what the power. The wavelength that a CO2 laser outputs is not best for cutting metals.

However, if you add oxygen as a cutting assist in the cutting process, metals can be cut, but we do not advise this as it is very dangerous.

  • I know you cant cut it but can you etch stainless steel with the laser?

    No you cannot sketch any kind of metal unless its coated from the molecular level or having it coated individually. However there are some types of coatings (Thermark and Cermark) that you can use to coat the steel so that you will be able to use our laser machine to sketch any metal.

  • If I build a Laser with the components on this site, can I cut the 0.1mm and 0.2mm board? Is it cut in optimal conditions, or if not what you recommend ?!

    What material is the 0.1mm and 0.2mm board?

    Additional Information:
    Steel sheet


    Additional Information:
    Steel Sheet

    Additional Information:
    Thanks for the response. CO2 lasers unfortunately cannot cut metallic materials. Metals are best cut with other types of lasers, or by using oxygen assist. The oxygen assist method is not encourages as the combination or CO2 laser and oxygen is very volatile.

    Additional Information:
    and I can not do this laser to cut the steel plate, but instead of the CO2 tube I put the oxygen tube, or do not I know ?! Do I have a chance in the products on the site to create a laser for 0.1mm and 0.2mm steel sheets?

  • Trying to cut 24, and 26 G steel sheets in various shapes. Will CO2 laser be enough? And will it cause alot of heat in the product?

    A CO2 laser will not be suitable for cutting steel. You would likely need a very powerful fiber laser to cut steel, and even then you have to take into consideration the reflective properties of steel which can pose danger to the machine.

  • Can other types of laser tubes work with the controller you are selling, for example, the 80W Reci tube?

    Yes, other CO2 laser tubes will work fine with our laser controller (including the Reci tube). Our laser controller is a digital based controller that controls the laser tube power supply, the motor drivers and other peripherals by outputting digital signals to these devices.

  • Can you shortcut the usb controller that comes with the blacktooth laser to hardware reset it?

    The USB controller does not have a reset button installed on it.

    You have some alternate options however:
    - You can remove the USB connector and re-insert it.
    - Set the USB to use external 5v by removing the jumper near the USB connector, use a 5v wall adapter and install a switch along the 5v DC power line to turn it off then on. You can use a momentary push button switch to do this.

  • 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)?

  • WHAT SOFTWARE CAN BE USED WITH THE BLACKTOOTH LASER CUTTER?

    If you take the standard parallel cable BoB (Break Out Board), then you will need control software (Mach 3 or EMC2) and CAM software to make your G-Code (such as CamBam). Personally I use CamBam and Mach 3, they work beautifully but don't expect to turn them on and know how they work out of the box. Give yourself a few weeks to get familiar with the basics. CamBam is VERY powerful software for it's price. I'm surprised how much I keep learning on what I can do with it...I highly recommend it if you want as much control as possible.

    Mach 3 + CamBam as a bundle costs $310. EMC2 will give you a free replacement for Mach 3 and is exclusively for Linux.

    If you use the USB BoB, it will cost an extra $75 + $75 for the software. This is an all-in-one package so no need for Mach 3 or CamBam.

    For etching rasters (jpeg, bmp, tiff, non-vectors, photos), I highly recommend PicEngrave. It has been a labor of love for the past 9 years and John has done a wonderful job with it. It easily compares in quality compared to software that is in the $200-$300 range. John's software runs $40 and can be found here: http://picengrave.com/ (don't let the modest website fool you, this stuff can do amazing things). DotG and the Mach3 engrave plugin are two other options and instructions can be found on Dustans page in the gallery on buildyourcnc.com website.

  • WHAT SOFTWARE CAN BE USED WITH THE BLACKTOOTH LASER CUTTER?

    I would say mechanically, between the official build instructions, Warren's awesome blog (http://blacktoothlaser.blogspot.com/) and the tips in the forum, the blackTooth is a really simple build. The challenges come with electronics and software. There's a number of different ways to drive the laser and motors. A decent understanding of electronics and computers is a must.

  • For the XL Vertical Laser Machine I see it won't cut metal as it is only 80w. However, I noticed that you are working on 100w and 130w versions so will that be sufficient to cut through sheet metal? If so, how much longer until those are available?

    Cutting metal with lasers even at 100W and 130W is difficult. The main problem is molten is a byproduct of lasing, which can severely damage the laser.

  • When will 100W or 130W lasers be available for the vertical laser system? What will be the price point? Ballpark figures at least, please.

    100W and 130W lasers and power supplies can be equipped now, but we will have to special order them. Price point for the 100W will be estimated $150-$200 more than the 80W, and 130W $250-$300 more.

  • 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.

  • does the laser xl do well cutting 1/2 Ultraboard? (foam core w/ pvc face) Can it cut it with graphics applied? can it cut 1/2" acrylic?

    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.

  • 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.
