  • Originally bought the Blacktooth Laser kit, but the upgraded laser tube size and needed a larger casing. With that I need to upgrade the belts to a 36" run. Can you advise whether the mxl.08" timing belt is sufficent or do I need the .2"in.

    The mxl 0.08" pitch is fine for moving the weight of a gantry that contains a 40 watt laser tube and optics. I would not advise this timing belt for CNC applications that need to move heavy items such as spindles, routers, and heavier structures that are required to move these spindles and routers around.

    The mxl 0.08" pitch timing belt is also great for 3d printers.

  • Hi The larger Laser kit mentioned ready mid 2015 have you spec and price yet. Looked on ResDev page and could not find? Thank

    The larger laser kit is still in development. We have not confirmed a BOM, not found the best suppliers. The release is still on track for mid 2015, however. As you know our prices are the lowest in the industry for what the kits can do, you can expect this machine to be in-line with this.

  • Does the blacktooth laser cutter have a 'trace' ability or 'air cut' where you can visually see the proposed cuts to be made..i.e. visible laser?

    The blackTooth does not come with a beam combiner that allows a visible laser to be combined with the CO2 laser.

  • Do you have a laser kit that can be fitted onto another brand CNC router?

    We don't have a laser kit to retrofit another CNC router other than ours, but we can create one. Some things that may help:

    - You are located close to use so we can work closely with you to implement to retrofit,
    - or you can provide very detailed drawings or measurements so we can use them to create the necessary parts for the kit.

    Other things that you need to understand:

    - A laser has a number of parts that will bulk up the head of the CNC router causing a bit more inertia which may require lowering the acceleration for smooth ramping up and down of the velocity

    - The bulk of the parts required for the laser may restrict the travel of the x and/or y axes.

    - The nozzle of the laser will be offset from the end mill of the spindle.

    Can you tell me the brand of the CNC router that you would like to stick a laser on? (you can answer by submitting additional information.

  • 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.

  • Hi, whats the actual (with the fixed errata) laser electronic wiring diagram for the blacktooth? thank you

    Which wiring diagram are you specifically requesting? Due to your current model blackTooth? We currently have two wiring diagrams, Parallel Interface board (https://www.buildyourcnc.com/images/LaserWiringParallel.jpg) and the USB interface board (https://www.buildyourcnc.com/images/LaserWiringUSB.jpg). Also if you have the new model blackTooth with the control unit, we still do not currently have that wiring diagram in a document format!

  • 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 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.

  • I am interested in the GreenBull 4x8 CNC machine kit you have; I also wish to get the laser attachment but I was wondering if its possible to have the laser larger than a 40w, say in the 80-150w range?

    Currently our greenBull can only accommodate a 40W laser tube due to the size and current mounts on the spindle/laser hybrid assembly!

    However please contact 281-815-7701 for further assistance with the greenBull machine.

  • I bought a blacktooth laser from you about a year ago.. I am finally getting around to installing the laser tube and I noticed that my tube does't have the metal end on it like all the pictures I've seen. is this a focus lense and can I purchase one?

    As shown in the instructions the laser tube that was used was a different model which had the metal end, compared to our full glass tube models we currently ship with the machines.
    So there is no difference besides appearance between the two tubes.
    The focus lens should be placed in the laser nozzle assembly and not on the laser tube itself.

  • Do you have a laser system that works with the 4.1 blacktoe system?

    We do not currently offer a laser kit specifically for the blackToe, however we do offer a combination spindle/laser tube mount for our greenBull machine here: https://buildyourcnc.com/item/cnc-machine-laser-spindle-combo-head. You could probably modify that mount to suit your needs, or you can contact us directly to discuss a custom mount. We also offer all the additional equipment needed to begin lasing -- tube, power supply, mirrors, etc.

  • HOW CAN YOU ENHANCE THE BLACKTOOTH LASER CUTTER?

    Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

    Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

    Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

    Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

    Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

    To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

    A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.
