  • I am having issues with the laser firing. Seems like there is an arc in the end of the tube where the elctrode is but i am not sure if i am doing something wrong.
  • What kind of cooling system should we set up for the Blacktooth laser cutter laser tube? Can tap water be used? Is water temperature critical?

    The blackTooth's 40 watt laser tube can be cooled with simple tap water. A bit of anti-freeze keeps the tap water clean and free of algae. The cooler the water, the better output you will get from the laser. A great source of information can be found here: http://www.buildyourtools.com/phpBB3/viewtopic.php?f=8&t=3452

  • Im in the market for a laser cutter with the ability to cut 8'x4' boards (different materials) and up to 5" height. I bought a greenbull 10'x5' a while back from you guys

    Here's a link to the blackTooth laser that we sell, https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx. It will vary depending which materials you are using, but keep in mind on how deep you are cutting since the blackTooth only cuts 1/4" inch(dept) at a time.

    Additional Information:
    We will be carrying a 8' x 4' laser cutter in the near future. We will also design an attachment for the GreenBull to contain a laser tube at the head of the machine to convert a greenBull into a laser cutter.

  • How to wire the Laser Power Supply with an arduino & GRBL ? (I'm not using a blacktooth laser cutter)

    There is a th or tl on the laser power supply that serves as the trigger on a high or low signal. There is also a potentiometer "in" terminal that will accept a variable signal from 0v to 5v to control intensity. You can use either of these features to fire the laser tube.

    If you have gotten grbl to work, then, no doubtedly, you have the expertise to know the output features of grbl. If grbl allows a pwm output, you can tie this to the potentiometer terminal on the power supply. Otherwise, you will need to use a digital output to control the power supply using th or tl.

  • 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 SOFTWARE CAN BE USED WITH THE BLACKTOOTH LASER CUTTER?

  • 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.

  • I have been asked to provide an exhaust for the Blacktooth Laser Cutter CO2 40W. I see no specifications or guidelines for exhausting fumes from the machine. Can someone help me?

    Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses.

    The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present.

  • Diagnostics(Alt7) page-LED (4th from left on top row) is on. Having trouble configuring Limit & Home Switches. I think this LED is for pin 15. Any ideas where to look to diagnose?

    We have a tutorial on setting up limit switches here(

    ), also we have noticed that the limit switches are very sensitive, so we recommend using shielded cable, or having them wired completely away from any other wiring (ex: motor wires, BoB to driver wires, power wires, etc.).

  • Patrick, I am having issues with the x axis on the vlxl..very rough movement. What should I adjust? Check the rail spacing or can I modify anything in the software?

    Sounds like a wire may have worked itself loose. Did this just start happening? If so, check for loose terminals with the motor wiring. Did you solder the motor wires to the extended wires that lead to the driver? If not, I strongly suggest these wires be soldered and a heat shrink tubing cover the soldered connection to eliminate the possibility of shorting.

    Additional Information:
    I am just now starting to work with the machine. Was on vacation. It has never moved smoothly on the X. Was hoping to get some phone time with you or Juan tomorrow. All the connections are solid as far as I can tell. Nothing is interfering. I'm wondering if the rail spacing is off. It moves fine when I manually move it.

    Additional Information:
    If it moves smoothly when manually moving it, but the stepper motor runs rough, then it is definitely a motor wire connection. Also, check to make sure the driver is set to 1/16 microstepping and the motor amps is around 5.

    Additional Information:
    What gauge wire did you use for the motor to driver connection?

    Additional Information:
    It was the black wire that was included. Pretty sure it's 18. I was worried it couldn't take it. Some of the 18 I have seen is only rated for 2A. I can rewire with that 4-lead cable you included If you think I should. The connections seem solid so that might make sense.

    Additional Information:
    18 gauge is more than sufficient for this stepper motor wiring. We use 20 gauge stranded wires in the 4 conductor motor cable.

    Additional Information:
    Sometimes wires can get chaffed, or there is a conductivity issue in some wires.I'm wondering if it would be goo to do a test rewiring the motor to the driver, but not putting it into the cable carrier, just to make sure that is the problem.

    Additional Information:
    What do you suggest I do? Just go over the wiring? The 18 is fine for 5.5A? All the switches look right. Set at 1/16. What are the natural steps on this motor?

    Additional Information:
    I’ll check the conductivity on the wires. I can just re-run it with that four conductor. That cable works fine for you guys?

    Additional Information:
    The 4 conductor cable is the only cable we use for these stepper motors. It's a special cable used for motion applications.

    Here is a link to that cable that we sell just to confirm the cable we are discussing:
    https://www.buildyourcnc.com/item/electronicsAndMotors-cable-wire-20awg-wrcon


    Additional Information:
    Yeah, that’s it. However, I ran the stock File on the laser cutter, the duck, it seems to run fine it’s just when you make the small adjustments with the arrow keys that it’s so rough. The other problem is that the speed on the stock file is way too fast.

    Additional Information:
    Ah, the jogging speed. I did not consider this. You definitely need to reduce the speed when you press the arrow keys.

    The speed when running a job (the file) can be modified in LaserCad.

    Additional Information:
    So, I’ll look into that. Everything is done besides for Putting the tube on and adjusting the mirrors. When are you guys available for a quick phone call?

    Additional Information:
    In LaserCAD, go to the options -> system options -> User parameters. Make sure to click the read button to bring the parameters from the laser controller to the software. Our Key_Move_Speed is 100 and our X/Y_Home_Speed is also 100. I wouldn't go any faster than that. Curious, what are your values for these parameters?

    Additional Information:
    Key speed was set to 200 and XY was at 50. On the duck file on the machine, it says the speed is at 200. How can I import that file to change it?

    Additional Information:
    Much smoother after that change. File is still too fast, though.

    Additional Information:
    In the file, the speed is built into the geometry. You will need to open the file in LaserCAD, select the geometry and modify the speed. Make sure to change the intensity as well to compensate.
