Please conduct the following operation before installing the driver
1) The machine is on;
2) Keep the emergency button not pressed;
3) Data cable connected
1.1 Right-click "this PC", click "Manage".
1.2.Click "Device Manager", find "USBLMCV2". "USBLMCV4" or "Unknown Device" in "Other devices" or "Universal Serial Bus devices"
1.3.Right-click "USBLMCV2", "USBLMCV4" or "Unknown Device" and "Update driver"
1.4 Select "Browse My Computer for Drivers".
1.5.Find the corresponding file with window system in the USB drive, click OK
1.6 Click "Install".
1.7 Click “finish” if it is successful.
1.8 It will display "BJJCZ Device" in Device Manager.
Noted:
*It is recommended to copy and paste the files of the USB disk to the computer desktop or other computer disks.
*If the driver installation is unsuccessful, please refer to FAQ below
2. Open the software
Open the USB folder, open the "EZCAD for ComMarker" folder, and select the 110mm folder if the lens is 110mm. Open the software "EZCAD2". You can enter "text", import "picture" or "vector file" as shown in the figure below. It is recommended to select the text to test first.
3. 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)".
4. 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
5. Marking test
Place the test engraving material on the machine. Click "Red (F1)", the area shown by the red light is the marking area. Tick "Default Parameters". Click "Mark (F2)" to start marking.
FAQs
Q1: The driver installation was unsuccessful?
*Please make sure to use the copyrighted window system, if not, please replace it with another computer.
*Please try to replace a data cable, it is recommended to use a magnetic proof cable.
*It may be a computer port problem or a computer board connection problem. The front USB ports of a desktop case are easily damaged. Please try with the port at the rear or try another computer
* Make sure the machine is on, keep the emergency button not pressed and data cable connected
*Please contact after-sales staff or email us
Q2: The driver in the device manager is different from the instruction in this manual.
*It happens because another driver has been installed in the computer; it could be Lightburn driver or any other one which is for other laser machines. Please uninstalled the incorrect driver and don't forget to delete the driver.
Q3: The USB flash drive is damaged and cannot be opened
*Please visit ComMarker's official website to download the B4 driver and software.
*Contact after-sales team by email.
Q4: The red light preview works with a rectangle, but there is no mark or the marks are very light
*Please adjust the focal length; please refer to operation instruction step 4 for debugging methods.
*Contact after-sales team y email.
Q5: Cannot find dongle, software will work at demo state, or Fail to open Imc driver
*The machine is not powered on, or the machine is not connected to the computer. Please turn it on and make sure the data cable is connected to the computer.
Q6: Up and down button does not work, the machine does not move by press the button
*Readjust the angle of the coupling and re-fix it with screws
Q7. The size of preview and the engraving area is inconsistent with the size in the software, the red light preview is inconsistent with the actual engraving position, or preview and the mark are not horizontal or vertical but with angles.
*Import the calibration file we include in the USB drive together with the machine, please refer to step 3 of the operating instructions.
You can also ask for a new calibration file with the SN number with after-sales team by email.
*If the problem not solved, select "Parameter (F3)", select "Other "and "Red light pointer".
Input numbers in "Offset X" and "Offset Y"according to the actual deviation number based on the measurement with a ruler.
The number can be positive or negative. The red light will change in different directions at the positive and negative values.
*If it still doesn't work, please contact after-sales team by email.
Q8: How to change the physical marking area in the software?
*Click "Parameter (F3)", select "Field". Input numbers in "Offset X", "Offset Y" or "Angle "according to the actual deviation number based on the measurement with a ruler.
This function is important when you want to use a placing helper.
Q9: Some of the engraving areas are clear and other parts are light
*Please make sure that the field lens is clean, if the field lens is dirty, the laser light transmission is uneven. Please clean the field lens carefully.
*The front and rear of the optical path are not on horizontal level, because the 4 screws connecting the column with the optical path and the 4 screws connecting the machine table are not fixed properly, please loosen them again and fix again.
*Make sure the oval base of the pole is perpendicular to the pole.
*Re-tighten the screws of the metal parts supporting the optical path
Q10: There is only one dot of preview and marking laser
*The galvanometer is not powered, remove the cover on the optical path, and check whether the DB15 cable or DB25 cable is disconnected. Please reconnect if it is disconnected.
Q11: The preview red light is not clear, or there is even no previewred light emits
*Remove the laser head cover firstly.
Adjust the red light source manually, move and fix again, or disassemble and reinstall.
Q12: Nothing displays on canvas board when importing text or picture
*Please click the practical center button, the picture and text are in the center of the canvas
Q13: It is found that the laser becomes weaker and the engraving effect becomes worse.
* Clean the field lens with a clean cloth. Sometimes the lens is dirty by hand. Or it will cause field lens pollution if the lens cover isn’t taken off when marking, which will eventually result in weaker laser and worse marking result.
*If the field lens is polluted too seriously, a new replacement field lens might be needed.
Q14: Which version of Lightburn software is right for ComMarker B4?
*Please buy "Add Galvo devices to existing license key" if you bought the software for gantry type. Please choose the "Lightburn- Galvo license key if you haven't bought any licence".
