2.What materials can be carved, how to fix materials?

Objective engraving material: “Smooth, Organic, opaque, Non- flame- retardant material For example: Wood, Gray cardboard, bamboo, Leather etc.

Unsuitable engraving material: ” Those material unable to burn &focus“ For example: Pure metal(without coating), transparent plastic, White paper(Astigmatic),PP plastic etc.

Fix the object to be carved with a silicone pad and rubber band or other auxiliary tools.

3.How to adjust the focal length!

We will use the gray cardboard to carve as an example to explain, please follow the instructions to do your operation. If you are working for the first time, you can ignore this step, because factory default settings the focal length of the gray cardboard, there is no need to do any adjustment. If you need to carve the object in different thickness, you need to place the object in the engraving platform and adjust the focus manually, when in the first operation, it is recommended to use a gray cardboard (in the package list) to carve; The method of adjust the focal length as follow:

How to replace the old laser tube!

— Choose a picture from “Photo Gallery” or Drag a picture from your computer into the middle of the control interface.

—Edit image size, insert text, position engraving area.

— Set burning time and control engraving.When you browse the photo gallery or edit your favorite pictures, you can click the right mouse button to bookmark “My Collection”.

—Adjustable focusing lenses

Adjustable focusing lenses

The smaller the focus adjusted by rotating the focus cap, the better the effect of engraving, and the higher the accuracy.

Fixed the surface of the carved objects at the level of the bearing table, put on the focusing glasses( sent in random) (maybe will not adapt it at the beginning, just to be used as focus),rotate the focus head manually, shown in figure:

Observe the light down to the surface in the smallest point of the object , when the rotation to the smallest point, indicating that the focal length has been adjusted, note that the smaller the focus adjustment, the image engraving effect is more fine, if the focal length is not adjusted, there may be no image to be carve;

—Determine engraving area

Point positioning

Drag pictures

Frame positioning—Adjust picture size

FAQs

— What materials can be carved, how to fix materials?

a.Whether the material is suitable for carving, The machine is engraved by burning, so it is impossible to engrave inorganic materials such as stones. In general, materials that can be Burnt black with a lighter can be used for engraving, but plastics that be added Anti-combustion and pure white paper that aasy astigmatism can't be burned. Some paper can't burned because of adding powder or film.

b.Whether the surface of the engraved material is flat.

c.Whether the object is fixed well.

d.Whether the focal length is adjusted accurately.

e.Is the burning time set properly?.

— Why does the machine keep hitting a straight line?

The chassis is driven by a stepper motor. If the weight of the load is too heavy, the motor will not be able to complete the drive. Please reduce the weight of the engraving object.

— The power connection is normal, but the machine does not move?

The mechanical structure may be stuck by foreign objects. For the first time, please remove the fixed mechanical EPE. If the machine lacks maintenance for a long time, you can add a small amount of lubricating oil to maintain the mechanical joint.

— The power connection is normal, but the machine does not move?

The mechanical structure may be stuck by foreign objects. For the first time, please remove the fixed mechanical EPE. If the machine lacks maintenance for a long time, you can add a small amount of lubricating oil to maintain the mechanical joint.

—Laser running to one side?

The mechanical joints have sand-sized foreign bodies that affect the mechanical work, and can quickly slide back and forth to eject foreign objects.
