Question #: 9047

Question: What is the largest thickness of material that the BlackTooth can accomodate

Current Solution

A standard 40W CO2 laser will cut up to 1/4" thick of material, be it wood, acrylic, card stock, leather, fabric, foam, cork, etc. (Decent speed and final cut are heavily dependent on a strong air assist upgrade)

Metals cannot be cut due to the power level and wavelength of the CO2 laser. But it can be marked with special solutions like Cermark or Thermark.

Other Possible Solutions to this Question

  • I'm considering the purchase of your Blacktooth laser. I will be engraving on my wood blocks that are two inches in thickness. Will the Blacktooth accomodate this thickness material?

    Yes, the blackTooth actually has a base that is open, so you can set the blackTooth laser cutter on a surface that is depressed as much as you need so you can accommodate a work piece with very large heights.

  • 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)?

  • I am looking at buying the blacktooth-laser-cutter-engraver-40w. Can you give me some idea of the types and thickness of material this machine will cut and/or ingrave?

    Considering that "materials being lased by may emit gasses that are harmful to humans (corrode human tissue and cause damage to respiratory organs). Always read the MSDS (Material Safety Data Sheet) for the material to be lased. You can find these MSDS from manufacturer websites for the material you are considering for use in the laser system."
    We successfully have worked on Thin sheets of Brasswood, glass, foam, plexi-glass. The thickest materials you will be able to successfully cut is 1/4".

  • I was wondering what thickness of material the 'book' design can handle on the z-axis?

    The book CNC build has a restricted Z-Axis travel due to the design of the Z axis assembly. This machine is best used for sheet material. You can modify the bed of the machine so that there is a depressed area that thicker stock can be placed. The travel of the book CNC build is approximately 5 inches. Increasing the dimension of the gantry from rail to rail will allow a longer z-axis assembly increasing the z-axis travel.

  • What is the Max thickness of wood that can be placed in the 4x8 cnc milling machine?

    Tricky question. That depends on the way the table is built. If the table is built with a step down area, you can put as thick a material as you want. If the table is flat, the clearance is 6 inches. Now, the thickness depends on the size end mill you insert into the collet. If you use an end mill that has a 2 inch cutting length, then your material thickness is 4 inches without a spoilboard. If you need to mill thick material, I would suggest that you fashion the table accordingly so the table can accomodate any thickness you desire. That's one of the great aspects of the buildyourcnc machines, adaptability.

  • I have been using a Blacktooth for some time, with Vectric2d and Mach3. I have always found that the laser burns a hole before moving off. I have always set material thickness at actual value. Should it be set very low? Also, of the many post processors supplied with 2d, which is best for Blacktooth?

    If you have the laser firing using the Z direction, then you want to make sure that the thickness and clearance plane is extremely small. The time it takes for the software to think that the z axis has lowered to the depth set in the design is causing the laser to stay on in a single position for too long. Make sure that the depth is extremely small, like .0001" or the smallest amount allowed by the Vectric software. Also, make sure the clearance plane (the height that the z axis would raise to clear any protrusions like clamps and the such) is extremely low.

  • How thick can the material to be engraved will fit inside the BlackTooth machine

    The thickness of material that can be cut or engraved is addressed in other CSL answers.

    The thickness of material that will physically fit into the machine is limited by the distance from the bottom of the cabinet to the laser nozzle, which needs to be at a distance from the workpiece determined by the focal length of the lenses used. (2 inches is standard in our machine.) The standard cabinet of our blackTooth has a cut out section about 25 inches wide designed to allow a sliding tray to be used to easily change workpieces. You could allow for material of any reasonable thickness by adjusting the thickness of this tray so that the surface of your workpiece is the proper distance from the nozzle. You could also modify the cabinet as needed to accommodate special sized work.

    If you need to lase very large workpieces, you might consider our Vertical Laser XL, found here: https://buildyourcnc.com/item/cnc-machine-vertical-laser-xl, or adding a laser tube to the spindle of one of our conventional CNC machines, such as this: https://buildyourcnc.com/Item/cnc-machine-laser-spindle-combo-head.

  • 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.

  • 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.

  • WHAT IS D.O.F OR DEPTH OF FIELD FOR THE BLACKTOOTH LASER AND LENS?

    Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

  • What are the acceptable materials that I can cut?

    The machines on this site can cut a wide variety of materials. If there is an end mill (cutting bit) that is available on the market, the machine can cut it. The thickness is only limited by the end mill length. This is possible with these CNC machines and other machines on the market because the machines can be controlled in such a way that the material can be cut using depth per pass, feed rate, and spindle RPM.
