Tips for laser engraving

1. Some engraving suggestions on solid wood and hardwood?
 
When carving hardwood, we recommend covering the surface of the wood to reduce the infiltration of residue into the engraving area and to be easy to clean.
 
Use the "bottom to top" engraving mode. In the laser software RDwork we use, you can change the working mode of the laser head, allowing you to engrave from bottom to top instead of the usual top to bottom engraving. This has the advantage of reducing smoke and debris from being drawn into the engraved area as the laser head moves.
 
After the engraving is completed, use some glue to clean it. Because the hardwood gum is black when it is burned at high temperatures.
 
2. Can you really carve glass? What are the skills?
 
The first thing to know is that not all glass is flat. Although you may think that you need to buy some more expensive and more expensive glass to get better results, it is not the case. We have many customers who use the glassware of the wholesaler to engrave, but the engraving effect is also very good.
 
For the engraving glass we give you some advice:
 
With a lower resolution, it is only about 300DPI to get better results;
 
Change the black in the graphic to 80% black to improve the quality of the engraving.
 
We found that laying a wet tissue on the glass helps to dissipate heat and improve the quality of the engraving, but make sure the paper is not wrinkled.
 
Use a finger or paper towel to apply a thin layer of soap to the area to be engraved, which also helps to dissipate heat;
 
Use ScotchBrite or similar items to polish engraved areas and remove glass fragments
 
3. What should you pay attention to when carving on plywood (plywood) or light wood?
 
This material is more suitable for use in the field of cutting rather than engraving because the texture of the plywood may be uneven and there are different layers of glue inside. When you are carving on it, the material is very important, uneven, or a lot of glue, especially less will affect the engraving effect. Of course, if you find a better quality plywood, the engraving effect is still very good, such as woodcut painting. If you want to know more in detail, you can see a series of tutorials we have done on wood carving.
 
4. I want to expand my business to leather. Is this difficult?
 
Laser engraving or cutting leather can be, and we also have a lot of customers in this industry, want to customize the wallet, handbag LOGO
 
5. What is the best setting for carving artificial leather?
 
This will depend on your machine and wattage, but you can find the laser parameter table on the CH Laser website. If in doubt, you can start the test yourself at a relatively high speed and low power. Because of this, as long as you don't move your material, you can sculpt again until you get the effect you want.
 
6. I hate wasting materials. What are the cool projects that laser engraving machines can use for waste?
 
Using scrap is a great idea not only to create new projects, but also to use scrap to test more challenging engravings such as photos. We have seen many customers using waste to make a variety of things, such as small acrylic lighting signs, accessories, labels and more.
 
7. I have an Apple computer, can I use my CH laser engraving machine?
 
Our system can run Windows-based design software, and most of our customers choose CAD and CorelDRAW. The MAC computer can't connect directly to our system, but you can install a virtual machine to run windows to use our machine.
