DP Lasers Software Questions

  • My focusing dots are not aligned any longer. How can I get them back to overlapping at the focal point?

    First of all, you have to find the focal point again manually. This requires you bypassing the interlock if your setup is class 1, so we recommend that you contact DP Laser Customer Service to ensure this is done safely. There are also instructions in your laser system’s user manual that will explain this procedure to you. 

    Once the focal point is found manually, you simply take a flathead screwdriver to focus the external aiming diode to match the size of the aiming diode from the laser marking head. Then, adjust the hardware so they overlap at the focal point you found manually and you are done.

  • I need to engrave into my metal, what settings can I adjust to get this effect?

    Depending on your laser series and wattage, engraving can range from .004” to just a few microns. Our lower power models can get depth but it is going to take a lot of passes and time to get that depth. 

    The best way to get depth with any of our lasers is to make passes with a step size of lower than 30. You can make more passes in the same time with a higher step size but depending on your substrate, you might not get the depth you need. You can add pulses to assist this, no more than 10 with our 10 to 20 watt systems, no more than 20 with our lower wattage lasers. 
  • My marking is not the contrast that I need it, what settings should I adjust to fix this?

    To get a darker contrast with our laser systems, the best settings to change are pulses and step size. Pulses allow you to hit individual pixels multiple times before moving to the next giving you a darker contrast and a little more depth. Please note that excessive pulsing can actually cause carbon build-up, which can easily be removed, and raises the marking from the material’s surface. Step size allows you to change the spacing of these pixels or dots. You can space dots away from each other, or you can move dots so close that they overlap. Please note that changing your step size does in fact change your marking resolution. The higher the value, the lower the resolution and the quicker your mark will be. The lower the value, the slower the marking gets as you can create more dots to mark. For filled items, this will ensure no space goes unmarked. If you are marking an image, this will over-fill your pictures giving a blurry effect. Do not go below a step size value of 40 for pictures. 

  • I imported an Image/Logo, but the clarity is not what I would like. What can I do to fix this?

    DP Laser’s can provide very high-resolution markings (up to 1200 dpi in some cases). Thus, the best way to achieve clarity is to import the highest resolution graphic possible. DP Laser’s software will dither the file and layout the dots perfectly for laser marking onto a variety of surfaces. If you do not have a high-resolution image, our software will import the file at its optimal size for laser marking. If you need it bigger, you can resize but the image quality will suffer. You can adjust the image’s brightness and contrast to improve quality. 

    Please note that if you are marking a picture file onto a dark anodized aluminum surface, that you will in fact have to invert the file to get the proper imaging to appear. Right click anywhere empty in our software’s composition grid and you can change the background color from white to black. This will assist with your imaging onto darker substrates. 

  • My Data Matrix is not reading, what can I do to fix this?

    Same as the barcodes, resizing of a data matrix must only be done by the Module Width sizing. Otherwise, you will destroy the integrity of the Data Matrix. 
    DP Laser’s software allows the user to control sizing by cell arrangements or you can select the auto-sizing feature that will change your Data Matrices to the optimal size based upon your data input. 

    Additionally, Data Matrices will have trouble reading if your marking has over-filled the modules. To prevent this, you can reduce your marking parameters or you can change the Module Width Reduction to a value of 1 or 2. For larger Data Matrices, this number can be as large as 4. This will reduce the fill of the modules automatically providing you with a little faster marking that has much tighter filled modules. This will prevent any marking from over-filling the modules.

  • My barcode is not reading, what can I do to fix this?

    First of all, the material color is quite important. If you are marking on a white surface, no inversion or quiet zones are needed to get the barcode to read. If you are marking on a dark surface, you must invert the barcode and add quiet zones (QZ). If you are marking on a reflective or brushed metal surface, make sure you have good contrast, either inversion or no inversion is fine, and it is recommended to mark a filled rectangle first at low power to remove some of the polished effect.

    Next, make sure that you resize your barcode using Module Width sizing. Not the typical drag and resize using the mouse. This will destroy the integrity of the barcode and will render it unreadable.

  • What about Adobe Illustrator and Corel Draw Files?

    These files can be imported. 
  • What are the file types that DP Laser’s Software imports?

    You can import any .jpg, bmp, tif, gif, plt, dxf, dwg, and svg file that you want. Please note that vector files must only have the marking data in the file. No drawings or anything extra as that will import as well. 

  • Does DP Laser’s Software import logos and graphics?

    Yes.

Dapeng Laser Marking System Hardware Questions

  • 【Symptom】 Machine will not engrave or engraves with poor quality

    【Possible causes】
    • Defective, damaged or misaligned Machine

    【Solution】
