We offer a 4'x8' laser system that uses an 80 watt laser tube.
Vertical Laser XL 4'x8'

Our blackTooth 24"x20" laser uses a 40 watt laser tube due to the internal size constraints and that the laser tube is mounted on the gantry for ease of aligning and maintaining better power at the cutting end.

Power is measured in watts. The 80 watt laser tube can output more than 80 watts of power; however, it is not advisable to run the laser tube above its rated power.

This video will illustrate how to test for laser power:

What is the peak power of the 80 watt laser tube?

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.

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.

Good day to you! We haven't communicated in quite some time! I am still wanting to pursue a 4 x 8 CNC spindle and 80kw laser system! Please respond so we can put this together!

That shouldn't be a problem. I will need the current rating for the motors. We can subtract the price of the motors. and you can add you own. If you want us to solder the cable to the round connectors and them motor, you would need to send the motors to us.

Let me know and I can send a paypal invoice for the redLeaf without motors.

Yes, other CO2 laser tubes will work fine with our laser controller (including the Reci tube). Our laser controller is a digital based controller that controls the laser tube power supply, the motor drivers and other peripherals by outputting digital signals to these devices.

Can other types of laser tubes work with the controller you are selling, for example, the 80W Reci tube?

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 THICKNESS OF MATERIAL CAN THE BLACKTOOTH LASER CUT?

Yes, the vertical laser XL (VLXL) can use a laser tube with a higher wattage than 80 watts. The maximum wattage depends on the length of the laser tube. As the wattage of the laser tube increases, the length of the laser tube also increases. The inside clearance of the Vertical Laser XL will allow a 130-watt CO2 laser tube to be used.

[510] Can this machine use a bigger laser tube than 80W?

The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



BYCNC Response:
Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

There are several CAD/CAM programs out there for MacOS. Here is a list of a few: http://www.macuser.de/forum/f53/3d-2d-cad-395058/#post4499316
I've also read good things about punchCAD: http://www.punchcad.com/
Of course, there is always SketchUp if you are in a pinch. There are a few CAM plugins for SketchUp as well, but I've never used them, so I can't vouch for them.

CAD/CAM will get you as far as designing your parts and producing the g-code, but if you also want to run the CNC machine with your Mac, you will need a piece of software similar to Mach3 or EMC to run the g-code. I haven't been able to find anything like these programs that runs on Mac, so you may have to run Mach3 or EMC in Windows using Boot Camp or a virtual machine such as VMware or Parallels.

Personally, I would use the Mac to do all the CAD/CAM, then use a cheap PC to run the CNC machine.

Upgrade your mirrors to SI coated mirrors, using a HQ ZnSe lens and even pushing up to a beam expander will all boost power. The ideal order of experimenation for lowest cost would be changing out for a higher quality lens labeled HQ ZnSE lens. Next would be SI mirrors, which will absorb less heat and reflect better, the last would be to use a beam expander which expands the beam, reducing the heat signature on the mirrors and makes a tighter focal width.

CAN BOOST THE POWER OF MY BLACKTOOTH LASER?

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?

Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.
