1. Install the 200mm field lens after removing the 110mm lens by screwing by hand
2. Re-adjust the focus as focus length will change with the new lens. Please refer to the below Appendix 1 to Adjust the focus
3. Field lens 9 points calibration.
1) Open the USB folder, open the "EZCAD for ComMarker" folder, and select the 200mm folder. Open the software "CorFile2" (the software EZCAD need to be closed first).
2) Click “F1”, set laser source parameters, select “IPG” and click “OK”
3) Stick the 2 pieces of paperboard together on the back cover with tape and put it on the work table.
Note：
Please make sure the paperboard flat on the table
4) Click “F3” mark 9 points rectangle, and it will mark the following graph on the right
5) Click the button on the top-right corner to change the pattern until it matches the marking result on the paperboard
6) According to the coordinate position of each point corresponding to the marking graph and the graph displayed by the software.
Take point 5 as the center coordinate (0, 0).
Use a ruler to measure the corresponding coordinates of each point on the black photo paper, take the absolute value (accurate to one decimal place) and fill in the corresponding coordinate column of the dialog box.
Click "OK" to return to the upper interface after finishing
Notes：
Make sure the ruler is absolutely horizontal or vertical and measuring lines goes through the 9 points when measuring.
7) Click "F6" to generate "calibration file". The following dialog box appears, please specify a file name for the file, otherwise it will fail to save, such as "200 B4 ComMarker". Be sure to remember the file directory location
8) Click "F7"to verify calibration, open the calibration file just saved. And click "F8" to mark the calibrated rectangle.
Notes：
If it is a regular rectangle like the picture on the left, it proves the success of the correction. If the shape of the picture on the right is seriously deformed, it needs to be recalibrated.
9) Import the calibration file for 200mm lens in the software EZCAD2, please refer to Appendix 2 to Import the correction file
Appendix 1: Adjust the focus
Press up or down button to lift or lower the laser head until the three red light point overlap, which is the best focal point.
The measuring focal length of this machine is _______mm (110x110) and _______mm (200x200),and the measuring distance is the length from the bottom line of the laser head to the surface of the engraving material.
This parameter is measured manually, and each device has different focal lengths due to changes in laser sources and field lenses.
Note:
Before the machine is out of the factory, we have done red light correction (for 110mm lens). At the position where the three red light spots overlap, the laser emits the strongest light. However, due to transportation reasons, the focus point of the red lights you received may shift, and the focus point would not be the best focal length. Please operate as the following steps:
1.Place the stainless steel test plate on the machine table
2.lift up or down the laser head to the best focus point according to the number in handwriting above
3.Turn on the machine, connect the computer with the machine
4. Import the "TEXT" for testing, select the default parameters, and tick the "continuous part" button.
5. Press "red (F1)" to ensure it'll mark on the test material. Click "mark", and the laser would be continuously marking
6. Meanwhile, lift or lower the laser head and observe the obvious change of intensity of the laser beam. Stop when the it works with the strongest laser
7.At this time, loosen the screws for the two beams of the auxiliary red light
8. Manually adjust the relative position of the red light dots to make them overlap. And tighten the screws
Appendix 2: Import the correction file
Select "Parameter (F3)", tick "Use Correct File", select the file ending in .cor in the USB flash drive (or have been copied to the computer disk), and click "OK (确认)".
