Some netizens asked how to use a laser marking machine to mark diameter symbols. In fact, there are many ways to use a laser marking machine to mark special symbols, and they are also very simple. Now I will tell you how to use a laser marking machine to mark diameter symbols and some special symbols.

 Method 1: We can use the search engine to search for the diameter symbol on the Internet and then copy it, select the drawing text tool in the marking machine and paste it in the input box and click Apply. You can also directly copy "Φ" in this article.

 Method 2: We can first hold down the Ait key on the keyboard, and then use the numeric keypad on the keyboard to enter 42677. At this time, when we release the Atl key, the diameter symbol will appear.

 Method 3: Find the symbol list in the input method. Let's take Sogou input method as an example. There is a keyboard icon next to Sogou input method, which is the symbol list. We click it to find mathematical units, which contains all the special symbols we want.

 The above are some tutorials on how to use a laser marking machine to mark diameter symbols. However, garbled characters may occasionally appear during use. This is because our current font does not display this symbol, so garbled characters will appear. We can ｒｅｐｌａｃｅ this font with a suitable font, such as Songti Bold, which can easily display special symbols.

 The above are some methods we introduced to you on how to use the laser marking machine to mark diameter symbols and special symbols. We generally recommend that you use the third method or the first method directly because some keyboards may not be compatible with the second method. The laser marking machine software may also be incompatible. If you can see this article, you can also copy the special symbol directly from method one.

 I hope the large diameter method introduced above can help you solve the problem. For more problems, you can pay attention to our Junchuang Laser official website. We have a large number of tutorials and problem-solving methods for your reference.
