I just ordered a 5 axis one from the same manufacturer. The thing is that it comes only with chinese manual, but it looks simple enought that I can figure it out. By the price they charge, it worth trying. No way I would find another 5 axis stepper controler for this price.
I could also not find any info in the net about this boards, I don't realy understand why people are not commenting on those.
As soon as it arrives and I try it out I will give some feedback.
