Question #: 605

Question: WHAT CAN ADD TO MY BLACKTOOTH LASER CUTTER MEASURE THE TIME OF USE?

Current Solution

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.

Other Possible Solutions to this Question

  • I am building the Blacktooth laser cutter. What is the safest and most accurate way to test the output of the laser power supply WITHOUT connecting the laser tube? Can I use a standard multimeter and measure the voltage output of the laser power supply?

    You can test the power supply, but you will need to take extra special care since the voltage on the high tension line can be lethal. Go to this instructable to see all the step on testing the power supply:

  • 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 ARE SOME USEFUL MODIFICATIONS CAN APPLY TO 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.

  • what is the size/width of pulley and timing belt used in Blacktooth laser cutter ?

  • 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

  • what are the specs of the blacktooth laser cutter (dimensions and weight) when assembled?

    The blackTooth envelope dimensions and weight:

    - Length and width: 37" x 34"
    - The height: 11.25"
    - The weight: 70 lbs.

  • 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.

  • Does the blackTooth laser cutter can acrylic plastic?

    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.

  • I was wondering what the max depth is for something to go into the 40W C02 Laser cutter and engraver with blacktooth

  • 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.

  • Is the blackTooth Laser Cutter available for custom size orders?

    We will generally consider a change in dimensions or machine features if the change will be beneficial to other users as well. This is due, in part, to the time it takes to make such changes and that it maintains the desired functionality and expected safety.

    What dimensional changes do you wish for the blackTooth?

    Additional Information:
    I was hopping to be able to have a cutting surface of 2' x 4'

    Additional Information:
    We have that size in our queue to be designed. However, you may be more interested in the laser adapter we are designing for the existing CNC machines to house a laser tube on the z-axis of these machines. This will be a quicker turnaround.

    Additional Information:
    Is there a time frame possibly to having this adapter made as well as cost? I am possibly looking to start a business so I am looking for something I can use to mass produce some specific parts.

    Additional Information:
    There is one project that takes precedence to the adapter, so I would expect in two months time.

  • Where are the wiring diagrams for the blackTooth laser cutter?

    You can find the wiring diagrams for the blackTooth on step 105 and 106 on the list of instructions on the blackTooth page. Step 105 pertains to the parallel breakout board and step 106 pertains to the USB interface board.
