Thanks to all the participants for the comments.
By reading the thread, it is now clear to me what is the situation with Chinese SMT machines (Neoden, Charmhigh, Xjyingxing, etc. and unfortunately Smallsmt/Yuchengtech).
Taking into account the fact that we can not build a castle from the crap, I have a question in my mind. Namely, why can not work Open-source hardware approach in practice? We have created a lot of things in the West over the last centuries. Unlike the Chinese, what is that we do not know? (not video editing, photoshopping, etc.)
OK. it is the world's second largest economy by nominal GDP, and labor is inexpensive. Apart from this, what makes it possible for them to produce so cheaply, but we can not? I apologize for the off-topic question.
I just write the above, because this topic has started more than 2 years ago. This time for a professional would have been abundant enough to build a really good machine, write the software and test it. Not to mention if that this is done in teamwork.
Apart from some semi-finished work, there is no opensource solution currently available on this topic. In other words, can a good machine be opensource or it is conceivable only as a commercially available product?
