Question #: 13341

Question: Derek, got your email, can the greenlean large format perhaps handle the laser head?

Current Solution

The greenLean can potentially be adapted to hold laser equipment, but the laser tube would need to be in-line with the gantry and use mirrors for the laser energy to find its way to the nozzle.

It would be challenging to make room for the power supply on the gantry, but not impossible.

due to the weight of the z-axis, raster engraving would be pretty slow. If the machine was for cutting and vector graphics, the z-axis weight and inertia would not be an issue.

To experience the full features of laser engraving and cutting, it's best to stick to a sole laser machine like the vertical laser XL or the blackTooth. If you want both CNC cutting and laser to possibly mark the cuts made from the CNC machine, then the hybrid is a good solution.

  • What tolerance can I expect from your largest cnc machine and the laser cutter? Also, what depth can I get on the z axis?

    The largest CNC machine we make at this time (12/04/2015) is the GreenBull 6'x12' model. This model has 2 options for Z-axis travel.

    The short-z option has a total Z travel of 5.75 inches. From that you would subtract the length of the end mill used and the thickness of the spoil board to determine the maximum material thickness. (Example: If the end mill extends 1.25" from the collet and the spoil board is .75", then the material could be up to 5.75 - 1.25 - 0.75 = 3.75 inches in thickness). This is good for most sheet-type materials.

    The long-z option, used mainly for large 3D carvings, requires a custom frame and allows for up to 36" of travel.

    The tolerance of our machines, like any machine, depends on several variables. The major variables include the manufacturing tolerance, the type of machine control used, the precision of assembly, the thoroughness of maintenance, and the initial and ongoing calibration of the machine. Because we sell kits only most of these variables are outside our control. Therefore, we are hesitant to guarantee a certain level of tolerance for an end user. However, in our experience, tolerances of .001" are readily achievable with our machines.

  • Hi im interested in your new 4 x 8' laser , what is the thickest mdf sheet it can cut through ?

    We have not specifically tested for this data point, but a general rule of thumb is that an 80W CO2 laser can cut wood up to about 1/2 inch. Actual results depend on a number of variables -- power level used, amount of air assist, focal length of lens, number of passes, cutting speed -- and each of those has its own tradeoffs. We are planning to do some of these tests in the near future and post the results, so stay tuned for more in depth information.

  • What is the cut accuracy of the large format routers using roller chain? .005"?

    Accuracy is generally function of how well the machine will match the measurements of what is designed on a computer on a computer. However, if you are looking for the resolution of the machine, you can calculate the steps per inch using the formula:
    Steps / inch
    = ((motor steps) * (micro steps)) / ((tooth pitch) * (number of teeth))

    Depending on the micro steps and the drive sprocket (or drive pulley) you are using, you can achieve a wide range of resolutions.

    With our machines, you can easily achieve .001 resolution, but accuracy will be best achieved with proper calibration.

  • how much would your vertical laser kit cost without the wood components and door plastic shipped to Canada

    Good question. I will need to add up the cost. However, the complete kit with the wood components will cost in the range of $300 to $500 using freight.

    Additional Information:
    I will add a price option on the Vertical Laser XL page that shows the assembly price without the wood structural parts. Are you wanting the rails included in the price?

    Additional Information:
    Hi, I was expecting an email answer, I did not know that you answered. Also I am in Fiji, not Canada. There is a flaw with your question form, It would not accept Fiji because we have no postal codes, so I put in my old Canadian code so that it would accept my question.

    Yes we would need the rails and any mechanical and electrical components. Our plan is to build it against a wall in a shipping container.

    If you do not have a suitable freight forwarder I can ask at this end because people frequently receive shipping containers.

    Thank you,

    George

  • Can we use a more powerful laser tube in the blackTooth? Say, 100w from ColeTech? Are they just physically too large/long?

    If the laser tube is the same dimensions then yes, that tube can be implemented and take into account the required laser power supply and safety protocols on that high powered laser tube.

    Our blackTooth is a fixed machine and is only made for the 40 watt laser tube that we sell.

  • Can the Planet CNC USB controller be used with a laser engraver/cutter? Can the build your own CNC based on the Planet CNC USB controller accept a Laser head instead of a router?

    The PlanetCNC USB software, like most machine control software, can be used to control a laser engraver/cutter. The typical modification is to use the Z axis down signal to fire the laser, analogous to an endmill cutting into the workpiece from an initial position above it.

    For the second question, it is important to note that BYCNC machines are not based on PlanetCNC software, or any other particular machine control system. The machines themselves will accept standard signals from a wide variety of machine control systems, not just PlanetCNC or Mach3. This allows maximum flexibility for the customer to choose their own preferred software for this part of the toolchain.

    That said, our machines will accept a laser head either in lieu of or in addition to a spindle. Here is an example of a combination spindle/laser mount for our greenBull machine: https://buildyourcnc.com/item/cnc-machine-laser-spindle-combo-head. We have all the parts you would need to add laser functionality to your machine here: https://buildyourcnc.com/LaserComponents.aspx, if you feel comfortable assembling your own package. Also, feel free to contact our sales department for a quote if you need a custom assembly.

  • Is the Greenlean capable of cutting soft metals like aluminum or brass? Thanks

    Yes, the greenLean can cut metals such as aluminum and brass. The gantry and Y carriage was designed to be rigid enough to handle these types of metals. The typical metal cutting techniques should be used, such as high feedrates to reduce heat buildup at the end mill, or the use of cutting fluids or cold air used at the end mill as is necessary with most machines that cut similar metals. This is necessary since the aluminum has a rather low melting point and can clog the end mill.

    Additional Information:
    All of our machines are capable of cutting many metals, including steel and aluminum as long as the proper CNC machining operations are used like light fast passes, and if desired, using air cooling for better performance.

    Here is a video of one of our customer demonstrating aluminum cutting using air to cool the end mill.

  • I can't spot the differences between 4'x8' blackFoot and the 4'x8' greenBull (except for laser head option): please, can you tell me?

    Only our greenBull CNC machines will be able to use the long Z-axis, due to structural construction of the greenBull over the blackFoot.
    The height from the table top to the bottom of the gantry is: 4.25"

    Both the maximum cutting height and diameter, will be dependent on the specific end mill/router bit you plan on using, since they can vary in length.
    The maximum cutting height (useful to engrave or cut material)is: with spoil-board 3.875", without a spoil-board is 4.625"
    The maximum diameter will (estimated) is: 3"

    Specifically dealing with our greenBull long Z-axis CNC machines, depending on how you specifically design the table you can have more cutting height and a larger diameter clearance. If you only create a frame for the machine with a hollow center(adjustable midsection), allowing you to have a greater clearance.

  • Do you recomend distilled water or coolant for your 80W laser tube with the CW-3000?

    We use purified water, but adding some coolant can be a benefit. The addition of coolant can keep the water in a state that maintains no growth of foreign organism like algae and the such. Additionally, If you are in a colder climate, antifreeze will work well.

  • Can I put a laser on my cnc router that I didn't purchase from buildyourcnc?

    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.
