Question #: 13332

Question: engraving timing and power settings vertical laser

Current Solution

The rate at which the nozzle moves across the surface to produce a specific depth and how much power is needed for this will depend on the material that is being lased.

Shallow engraving in a raster like operation is quite rapid where the nozzle is swinging back and forth very fast. Deeper engraving for vector type of designs will depend on the depth, which also relates to cutting. The thicker the material to cut, the slower the feedrate, and higher the power will be necessary.

  • Can your 4' x 8' vertical laser/engraver be built with a 4th axis for engraving cylinders (baseball bats)?

    Absolutely, between the ribs that make up the structure, there is room to add other peripherals like an 4th axis.

  • Is there any precision or accuracy difference between the vertical and blacktooth lasers?

    I will address the two separately (precision and accuracy):

    Precision (repeatability):
    This is most closely related to the resolution. The blackTooth uses the same mechanical drive (timing belts and pulley) of the same ratios and specifications, so the two machines will be the same in this respect.

    Accuracy:

    The output of the machine (the final physical work) matching the input given to the machine (the design data or instructions for the machine to product the physical work. This has to do with both resolution and how well the machine will hold up over time and through environmental changes.

    With that said, both machines have very similar attributes in mechanics and structure. The overall structure is made of MDO (Medium Density Overlay) and has a very low coefficient of linear expansion with regards to temperature change, so accuracy will not be affected in any appreciable manner over time with the two machines. The Vertical Laser XL does use more industry standard rails to hold the heavy gantry, but this will be differ appreciably since the blackTooth will exhibit rigidity by virtue of its size.

    It really is best to consider the application and size as the main aspects of deciding between these two machines.

    Hope this helps.


    Additional Information:
    We're looking at getting the vertical so we can run both large and small jobs on the same machine. It sounds like running a small job on the vertical (using a positioning jig) would provide results at least as
    good as running the same job on the blacktooth. Does this sound about right?

  • How would LinuxCNC be used with the vertical laser?

    It is possible to use LinuxCNC for laser cutters and engravers but not advisable. The efficiency and control with traditional CNC control programs cannot match that of Laser controllers. This is because laser controllers are very good at matching speed with power, especially with raster image burning. Moreover, controlling the laser tube while cutting and engraving is very built in with gcode. Special software can be used, but the processing and execution is not efficient.

    Laser controllers and associated software have matured well and can do cutting and engraving very well and is worth the extra expense.

    If you are still interested in getting LinuxCNC to work with the laser, let me know and we can discuss this in great detail on this FAQ.

    Additional Information:
    A better question might be "What are some good ways to control the vertical laser directly from a Linux machine without having to hop through Windows?" Let me know if you want me to post this as a separate question.

    If I were buying the blacktooth, I'd order the parallel port board for it and skip the anywells controller -- I notice that you don't show that as an option on the vertical, which is what's generating this question.

    Some background: All of our CAD/CAM is done in Linux (openscad, freecad, librecad, cadquery, blender, pycam, python gcode generators...), we use git and Makefiles and other automation scripts extensively, and we need to be able to avoid doing the double-hop from Linux via Windows to get files sent to the laser.

    An example use case is that of being able to say 'make' in a project's directory on any Linux machine on the network to ship the file to the laser, including power settings etc. Needing to ship it to Windows first, and then manually mouse around to set power etc. is what I want to avoid.

    With Epilogs, I used to always bypass the Windows/Coreldraw toolchain by using Gershenfeld's cam.py, sending PCL from Linux straight to the Epilog.

    Something equivalent to that -- being able to run a script in Linux to convert and ship the file straight to the laser -- is what I'm planning to do here. I mentioned LinuxCNC because it's what I'm already using for our mill, and I'm comfortable hacking on it. I'm not wedded to LinuxCNC for a laser, but I am looking for open-source flexibility and future-proofing.

    We don't even have any Windows machines any more -- we got rid of the last of them years ago, and I'd like to avoid going back.

    Additional Information:
    I've split the more general Linux use case out as a separate question at https://buildyourcnc.com/FAQ/13989

    Additional Information:
    Starting to find some answers -- forums have a thread which addresses some LinuxCNC questions at http://www.buildyourtools.com/phpBB3/viewtopic.php?f=8&t=3452 for instance.

    Additional Information:
    Example LinuxCNC config for the buildlog 2.X laser is at https://github.com/jv4779/2x_laser

    Additional Information:
    I'm going to need some time to digest this information. Curious, are you able to develop a program to change the g-code if need be? Will you be doing vector style cutting operations only? If so, the process may be pretty straight forward.

    Additional Information:
    Before we adapted the blackTooth laser to use the laser controller, we operated the machine using Mach3 and the z-axis direction signal was the chief mechanism to fire the laser (down=on, up=off). It worked like a charm. It would be better to use one of the output triggers to do this for safer operation; however.

    Additional Information:
    Blacktooth adaptation of the above buildlog config can be found at http://www.buildyourtools.com/phpBB3/viewtopic.php?p=18157#p18157

    Additional Information:
    Answering the earlier comment (is that you Patrick?) -- yes, we'd be doing vector primarily, though my wife (and CEO) is salivating over the potential for raster. I've got no problem writing a python script to massage gcode if that's what it would take to make things work. CAM is always a problem on Linux but I've been using a mix of things to generate gcode for milling (including just writing it by hand), and can get by as needed. Expect to spend this weekend looking around to see what others are doing.

    Additional Information:
    Yes. This isn’t Patrick. I manage the Customer Service section. I will try my best to help with this over the weekend and balance family time. Haha.

    I will check the links. If raster is a must, you can have two controllers controlling the machine using tri-state gates to the drivers. I did this for a customer a while ago to run CNC and laser with an external switch. You could use an external switch to switch between LinuxCNC operation and laser controller.

    Additional Information:
    This is Patrick. Auto correct on my phone turned the "is" to "isn't". Ha!

    Additional Information:
    The buildyourtools links doesn't really have much to do with LinuxCNC and the buildyourtools information on that thread (by MUK) implements a very similar configuration that I introduced when I first started selling the blackTooth (with the parallel control board). That style of configuration may work well with a LinuxCNC scenario.

    I would rather jump-in cold with the LinuxCNC solution and see if we can address each step. What CAM program will you be using? I ask this question because that program may have the ability to inject g-code at specific points where we can turn on and off the laser.

    Also, I'm going to merge the two FAQs once we pick the one we use the most often to figure this out. I'm also more comfortable using this Customer Service system to address the question for many reasons, one of which is I can tie these questions to the products directly to benefit many others.

    Additional Information:
    For laser CAM on Linux we have used cam.py in the past; it's just a python script, so modifying the gcode it generates is easy.

    I think we've reached a purchase decision; your responsiveness here has helped a lot with that, Patrick. It looks to me like we're going to be able to make this thing work, one way or another.

  • 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

  • What warranty is there on the 40W laser and power supply?

    Most of our products have a warranty that extends for 1 year; however, there are parts like end mills and laser tubes which are considered consumables. These parts, when used, become worn, or the usable life is decreased. Laser tubes are parts that, when used, shorten its life, and especially when proper methods are not used (i.e. running the tube with water), can drastically reduce the life of the tube. Therefore, the warranty for laser tubes are 30 days if the laser tube was not used.

  • What is the acceleration limited to with the laser tube vertical?

    With our new Laser/Spindle Combo Head for our greenBull, we kept the acceleration the same and had no issues at all with the tube (regarding chipping breaking etc.). So there is no specific limit to the machine (take into affect the weight of your gantry and the overall output of your motors), but here is the setup we have now:
    (with a custom greenBull gantry (4' x 8'))
    X-axis
    SPI: 910.069
    Vel: 400.02
    Acc: 12
    Y-Axis
    SPI: 911.023
    Vel: 400.02
