Hi,
I've decided to buy my first laser engraving machine from Gweike, model LG900N. What I'm confused about is what spare parts and accessories should I order with it ? Also what other suggestions can you give to someone who is buying their first machine from China ? This summer I plan on going to China and maybe visit their factory. What advice can you give to someone who is visiting factories in China for the first time? Maybe there is something ealse important that I missed ?
