I got the translation! 


你好,

我有一台你们的MLE-40全谱激光机。现在我需要另外买2种配件,可以吗?
1. 电源并联到USB控制板1块(全新的)
2. 主电源母板1块(全新的)
如果邮寄到北京,总价格是多少?

谢谢,
Mitch

I'll send it to them now from their contact page.  I'll keep you posted. 

Best, 
Mitch.

I'll post about this to the large WeChat group of expats in Shenzhen, and see if anyone can translate that for us. 

Mitch.
