could you make available a larger size picture of the exploded view of the BlackTooth laser cutter? I would like to use for reference when building my laser cutter, but it is too small to be really useful.

You can control our 40W laser power supply (which controls the laser tube) with an Arduino, if that is your intention. The trigger for turning the laser on and off uses a 5V level. To control intensity, you can use the Arduino PWM output. If you want the Arduino to move the machine as well (providing pulse trains to each of the stepper motor drivers) then you will need to make sure you consider the processing speed of the Arduino so you will be able to run the stepper motors at the speed you need for the laser engraving/cutting.

Our laser controller do all of these functions. Here is a link to our laser control system:

Thank you! I am building a 3 axis cnc/ engraver and I think this would be a good option as well as the router head and the 3d printing head. How heavy is the tube? I may mount it directly onto one of the axis of the machine to eliminate the need to line up all three axis, similar to what you have with your xl engraver.

Additional Information:
The tube isn't that heavy, but when filled with water, it can get up to a few pounds. The key is to use the axis moving the nozzle for engraving as this requires fast back and forth motion. The cutting is generally dependent on the axes moving from vector to vector at a relatively slow motion, so this is not a problem.

I would like to build a low cost laser engraver/ cutter, can your 40w laser power supply be controlled with an arduino or is it only controlled by the controller sold here?

We did give out the plans for our machines many moons ago, but a few winters back we had to cease this practice as the night was young and full of terrors. Unfortunately we no longer offer the .dxf files or g-code files for any of our CNC machines.

To build a roll cart for your blueChick, check out the similar cart we created for our blackTooth laser. (https://buildyourcnc.com/tutorials/Tutorial-sketchup-fabrication-fabricate-cad-cam-dxf).

Many moons ago (when we were all a lot younger) you offered an export plan that consisted of various combinations of hardware/electronics and SketchUp of the CNC machine. Do you still offer SketchUp of your projects? I bought the new BlueChick and would like to build a roll-around cart for it. I might also wish to make modifications so a SketchUp would be most helpful.

The laser tube is a consumable item in all CO2 lasers, unless the laser tube can be recharged. My laser tubes will most likely work as long as the mouts are the same size. Let me know the mount diameter and the length of space for the tube in the Epilog Laser Cutter and Engraver and I will let you know.

Additional Information:
My Epilog Summit (3.3) only works from Windows Millenium and 98. Notconsistently from WXP, but sporadic raster and vector combined does happen. I can't get it to work right w XP through Harvard Draw, Corel,Image Folio, Stika, DrawMagic or anything else I have. But Millenium isOK except for the advanced mapping to colors function is very difficult.When it does rarely accept a graphic from my XP system from CorelDrawEssentials or 8.0, it will allow complete control for photo etching -speed, power and shade mapping. It is the same driver for both mysystems but the control panel page looks different in the 2 computers. The laser takes 45 seconds to initialize after power on. You can use a USB to Parallel adapter cable for your laptop or modern computer connection. The laser needs the old style printer connection. Test your laser by holding all 3 power/focus/speed buttons until homed. Close the lid. "Online" for lase, any other button for laser off. Should be an audible beep every few seconds while your laser is functioning. This is not a motion test -only laser firing.

I have a 25 watt Epilog Summit Model 2000/25 laser engraver. I believe my tube is going bad due to limited vector cutting and no raster. Do you think there is a way to retrofit with your products to make it work well. Mirrors are new and mechanical is good. Thanks.

Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

As long as you have enough air blowing at the cutting location, you shouldn't have a problem with charring. A 40 watt laser should be able to cut through 4 ply chipboard.

is the 40W blacktooth laser cutter strong enough to cut through 4 ply chipboard with out horrifically burning/charring the edges? If you havent tried mabye you could as this is a must for anyone who will be using it to build architectural models. I would rather have this pre-verified before I give $2100 to have you build one

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:

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?

There is some variation in the outward appearance of laser power supplies due to sourcing through different vendors. However, the basic wiring requirements are the same in each case. For the unit with integrated laser controller, follow the diagram found here: https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/0/. The terminals on the signal side will have a 6 connection terminal block -- these are the ones labeled 5V, IN, G, P (or WP), L (or TTL-L), and H (or TTL-H). The High Power side will have 3 inputs for AC power, one high voltage lead, and one return line. Connect these as shown in the diagram as well: the return line goes on the "front" (beam exit end) terminal of the laser tube, the high voltage lead goes to the "back" terminal of the tube, the FG terminal (or G) receives the earth ground wire of the AC power cable, and the two AC terminals receive the line and neutral wires of the AC power cable (it doesn't matter in this case which wire goes to which terminal).

Hello, I'm wondering if you could make a larger laser cnc if someone asks for it? Something like 36" x 52". And how much would it be?

If you purchase the greenLean, you will get everything you need except a router, computer to operate the machine, and software to control the machine. You state that you have a computer. You can use this computer, but you will need to determine if it has a parallel port, or if you are going to need the USB controller option. As for the software, there are too many different options for you to choose from. We would not be able to tell you which to get, and how much it will cost you. This is a matter of preference. I can tell you, however, that you will need 3 types of software to complete a CNC project. You will need CAD software to design your design, CAM software to add tool paths and convert the design to g-code, and then control software to take the g-code and operate the machine.

Mach 3 is compatible with our electronic combo's that include the Parallel Breakout Board.
Planet-CNC is compatible with our electronic combo's that included our USB Breakout Board.

The parallel breakout board is compatible to a wide variety of software control packages. The USB interface board that we sell can only be used with the Planet-cnc control software.

If you are concerned with your computer (desktop) not having a parallel port, one can be purchased and inserted into a PCI slot on the motherboard. Some motherboard also come with a parallel port header (connector) on the motherboard and a simple cable can be connected to this connector to get that functionality on the computer. The former solution of getting a parallel port adapter card to plug into the motherboard is probable the easiest and least expensive option.

Is there a test button on the laser tube power supply? You can test the laser output by using the test button. This will help you determine if the laser tube is bad, or if you have wiring issues. Sometimes, wiring to he TL may not work as some controllers are set to active low, so you may need to wire the controller to TH instead.

Additional Information:
Additionally, the mA on the high tension line does not have any relationship to the digital trigger signal from the controller to the power supply.
