Question #: 14103

Question: When using the laser controller, what does "engrave beyond border limit" mean?

Current Solution

LaserCAD: Engrave beyond border limit.

This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • I get a "communicating unsuccessful" when using LaserCAD and the AWC608 Laser controller

    If you are getting the "Communicating Unsuccessful!" error when you are trying to communicate between LaserCAD and the AWC608 Laser Cutter and Engraver controller (after you have already tried installing the USB driver from the LaserCAD setup procedure), these are the steps you will need for a successful communication:

    - Open the Device Manager window (right click on the start menu and select Device Manager)
    - When you plug the USB cable from the AWC608 Laser Cutter Controller (USB Type B connector) to the computer, you should see a new item in the Device Manager, possibly under "Ports (COM & LPT)", or under "Other Devices". It may show as an item under "Other Devices", possibly FT245R and has an "!" in a yellow triangle.
    - Download the latest FTDI drivers from: http://www.ftdichip.com/Drivers/D2XX.htm
    - Unzip the files to a folder that can be easily browsed.
    - Right click on the item that appeared in the Device Manager when the cable was plugged in between the Laser Cutter AWC608 controller and the computer.
    - Click on update driver
    - Select the procedure to manually install the driver and browse to the folder containing the FTDI driver and follow the step in the driver installation wizard.
    - The item should now be located under the "Ports (COM & LPT)" and should be named "USB Serial Device (COM#)". The # will be the number you will use in the LaserCAD software.
    - In the LaserCAD software, click the "Select Mode" at the far top right of the Laser CAD user interface.
    - Make sure USB mode is selected.
    - If the Machine name with the correct COM number is listed, select it and exit the dialog window. Otherwise, click on "Add" and fill in the details with the new COM number.

  • Using the AWC708, my laser will not fire. The wiring seems correct

    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.

  • 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 max thickness of material that the 80W laser can cut in plywood?

    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.

    Additional Information:
    That's great information. What is your PSI of the air assist on your laser? What focal lens distance do you have? And where did you place the focus of the lens (at the surface, or within the material)?

  • 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.

  • What is the wiring configuration for limit switches on the laser controller?

    If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

    For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

  • What are some good ways to control the vertical laser from a Linux machine?

    There really isn't any good way to use Linux when using a traditional Laser Controller. If LaserCAD worked under the Linux OS, then that would work.

    Would you like to know an alternative to use Linux using maybe LinuxCNC? There are ways to do it, but you will find yourself deep in g-code and out of the box wiring configurations, most likely.

    Alternatively, you can create a dual boot scenario and put Window on the other part of the hard drive. This way, you would be able to run LaserCAD.

    You can also "attempt" to use LaserCAD in the wine environment, but I have a feeling that will probably not work.

    Additional Information:
    We're a small family-owned electronics and hardware manufacturer, using LinuxCNC already for milling. Dual-boot into Windows isn't a sensible option -- it would greatly reduce the utility of the machine. I have more information about our use case in https://buildyourcnc.com/FAQ/13985.

    Additional Information:
    Ok, fair enough. Then let's get into the details on how you can use LinuxCNC to operate a Laser machine.

    Do you have an idea what controller you will be using? Parallel?

    Additional Information:
    My first inclination was to use LinuCNC with the parallel interface board. Of that's the answer, then we might want to just add to the LinuxCNC discussion that's starting to firm up at https://buildyourcnc.com/FAQ/13985 rather than duplicate the information here.

    I'm open to other alternatives and am happy to hack; we make PCBs and cable harnesses as a business, so that's not a limitation either. One answer might be to use one of the open source controllers that are starting to show up.

    Additional Information:
    My turn for phone typos. ;-) I meant to say "If that's the answer, then..."
