Because this product is too large, it is not convenient to ship the whole machine, and it is shipped in the form of spare parts. It needs to be assembled by yourselves. We have assembled video and picture tutorials(there have a USB flash driver for you). If you don't understand in some places, look at the video, and the assembly is not difficult, the process is full of DIY fun. Our machine design is very reasonable, after assembly, you can start engraving without special debugging.
