  • What is the dot resolution (size) of the BlackTooth laser?

    The dot resolution of the blackTooth is a combination of two specifications of the machine:

    - The steps/inch (or steps/mm) which is the resolution but not the dot size
    - The size of the actual dot, which is not specifically related to the resolution.

    The steps per or resolution can actually be a range, since the driver microstepping can be modified.

    A simple formula can be used to determine the resolution:

    step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)

    if microstepping is set at 16 (1/16 on the driver) and you are using a pulley that has a pitch of .08 inches and 20 teeth on the drive sprocket

    = (200 steps * 16 microsteps) / (20 teeth * .08 inches)
    = 3200 steps / 1.6 inches
    = 2000 steps per inch

    To increase the resolution, just increase the microsteps on the driver.

    The actual dot size will depend on the lens you are using, the material being lased, the time period that the laser energy is applied to the material, and the focal height of the lens to the work surface material. The energy from the laser will converge to a point and create a dot on the surface (which is different than the kerf of the laser cut into the material).

    The dot will appear in different sizes depending on the material because, say wood, will burn causing a dot that burns the fibers of the wood and spreads a bit. The dot lased on the surface of a plastic, say Plexiglas, the dot will be smaller because the energy is absorbed only at that point, but since Plexiglas is a thermoplastic, a bit of the energy will melt the dot edges depending on the time frame (period) that the energy is applied to the surface.

    The focus of the laser energy from the lens looks like a cone converging to a point, then diverges outward after that point. Depending on the distance from the lens to the surface of the material, the dot will be bigger or smaller. You want to find focal point (where the energy is focused into a point). You can use the technique where you lay a material on a slope and lase that material along the slope to find the sweet spot (dot) and that will be your smallest dot, or kerf location. Remember that the kerf will widen or narrow within the material thickness depending on the focal length lens specification (the cone will be shorter or longer depending on the lens focal length).

  • What is the footprint size of the Blacktooth laser machine?

    The footprint of the blackTooth laser machine is:
    Length: 37"/ 939.8mm
    Width: 33"-3/4"/ 857.25mm
    Height: 11"-1/8"/ 282.575mm

    The height will change with the doors that open to retrieve your material/project the highest point will be 28"-1/4"/ 717.55mm

  • 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 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 THICKNESS OF MATERIAL CAN THE BLACKTOOTH LASER CUT?

    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.

  • What warranty is there on the 40W laser and power supply?

    Most of our products have a warranty that extends for 1 year; however, there are parts like end mills and laser tubes which are considered consumables. These parts, when used, become worn, or the usable life is decreased. Laser tubes are parts that, when used, shorten its life, and especially when proper methods are not used (i.e. running the tube with water), can drastically reduce the life of the tube. Therefore, the warranty for laser tubes are 30 days if the laser tube was not used.

  • 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.
