    Caution:

    The M1 Camera First-level Calibration will modify the system data once and for all and make it unrecoverable. If you are not sure whether yours needs calibration, please contact the xTool after-sales team at support@xtool.com to make sure.
    Since M1 Auto-measure works on the basis of the camera calibration file, please calibrate the M1 Auto-measure (Calibrate M1 Auto-measure) after calibrating the M1 camera, or there could be a significant error with the result of the Auto-measure.

     

    For scenarios where:

    1. There is a significant error with locating the material.
    2. There is a significant deformation of the image of the baseplate captured by the camera in Laser Flat mode.
    3. The camera fails to refresh (due to the missing camera calibration file).

     

    Items necessary:

    1. An A3-size (297mm×420mm) white paper* several;
    2. A computer running Windows 10;
    3. A transparent/ white tape;
    4. (With or without) An A3-size (297mm×420mm) metal/glass/porcelain plate or materials that do not deform as a result of the laser cutting and with an even and clean surface. (Calibration may fail due to uneven surfaces).
     

    Calibration Steps (video included):

    1. Lay the white paper on the baseplate in the white square area, edges to edges. If you have a metal plate, place it first the same way and then the white paper on top of it.
    2. Tape the white paper to the surface of the baseplate or the metal plate so it's fixed and flat.
    3. Download xTool M1-Camera calibration once.rar and unzip it.
    1. Launch FirstCorrect_GU.exe
    2. Each function can be tested by clicking on it and checking if the button turns green or not. It's OK if it turns green.
    3. Turn on the M1, and connect it to your computer via the original USB cable.
    4. Click "连接 Laserbox"（Connect to M1）.
    5. Click "加工网格点" （Engrave grid points）and it takes about 10 mins to finish.
    6. Click "取图" （Capture）.
    7. Click "生成校准文件" （Generate calibration file）and it takes seconds to finish.
    8. The ideal result is that the red grid points and those on the white paper overlap. Those with a slight deviation will be marked with yellow circles, and you may proceed to the next step if there are no more than 15 of them; while when there is a significant deviation, it will be marked with a red circle and you will not proceed to the next step. Check and make sure the paper is flat and repeat the process above.
    9. Click "上传校准文件" (Upload calibration file).
    10. The calibration succeeds with "出厂校准完成" (Calibration succeeds.) And you may test with a 3mm basswood. If there still is a significant error with locating the material, calibrate again.
    11. Last but not least, do not forget to calibrate the Auto-measure.Calibrate the M1 Auto-measure
