  • Execute the engraving process using the screen;
  • Computer editing file (.nc or .Gcode file) needs to be saved to the TF card first;
  • Inserting the TF card into the machine;
  • Select the file to be engraved and enter the engraving setting interface;
  • Move to the desired location and click on Set Origin;
  • Click on the edge patrol, if the position is not suitable, repeat the previous operation;
  • If the position is correct, click “√” in the pop-up window to start engraving.
  • Due to the resistive screen (which requires a certain amount of pressure to trigger, you can use your fingernail or pen);
  • The screen film is not torn clean, thus squeezing the screen, please remove the residue after inspection.
  • By the static electricity caused by the screen problem (the display from the chassis to take down, and then turn on again to see if the same situation, if not can be in the display and the chassis pad between the gasket;
  • Display line is not inserted tightly resulting in the inability to display (unplug the line to reinsert tightly);
  • Motherboard firmware is not fully brushed or brushed wrong leading to display errors (re-brush firmware);
  • The screen film is not torn clean, thus squeezing the screen, please remove the residue after inspection.

Not energized (check and energize);

Switch damaged (needs to be replaced);

Poor contact with the power cord interface (view and plug the interface tightly) ;

4. Motherboard short circuit (check and repair).

  • If there is a strange noise when returning to zero, check whether the X and Y axis limit switches are cocked, if they are cocked, please press them flat to make the limit switches work;
  • Incorrect firmware parameters, resulting in the wrong direction (please re-flash the firmware).;
  • The gear switch on the back of the machine is not set to “1” (please set it to “1”).
  • Abnormal noise when returning to zero (check whether the limit switch works and repair it);
  • The frame hits the frame during the movement (screws, the movement range is set incorrectly);
  • There is debris or pulling in the transmission range, which causes the jam (please check and remove the debris).
  • determine whether it is to be engraved or cut;

  • Drag in the picture to be engraved.
  • Find and enter the layer to set parameters (power, speed, etc.).
  • Determine the engraving range by “set user origin” and “edge patrol”.
  • Start engraving.

Gcode files can be generated by lightburn or GRBL software on your computer by

  • Open the software and drag in the files to be engraved;
  • Set the appropriate parameters;
  • Save the file as a Gcode file.
  • Wiring errors (you can check if other functions are also not working);
  • Wrong wiring sequence (you can test the voltage positive and negative through the tool) ;
  • Laser head damage (need to replace the laser head).

The machine itself transmits WiFi signal, if you need to use APP operation, you need to connect your phone to this WiFi first WiFi (you can check WiFi information by entering the setting interface on the screen).

  • Click next for pattern setting ;
  • Click next for parameter setting (size, power, speed) ;
  • Click Move for position selection.;
  • check whether the position is correct by the edge patrol function (repeat the previous step if it is not correct);
