As a beginner, I chose to make the basic model hello.D11C.serial.5V.1, and I made two for practice.

How to make it?

The PCB fabrication process is not complicated, but it takes more time than I thought. There are some details that require special attention, and I will introduce the failure I have experienced.

Failure

Please note that tapes must firmly attach to the back of the material piece, and make sure that it remains flat when you put it on the machine table. My first cutting test failed because it didn’t make sure that the material was flat（see the photo below，there is a gap between cutting piece and the machine table).
