Hi to all!
Got it, 2 days of hard work to investigate what happens and how stuff works. Many thanks to this thread.
Two problems discovered, both software related:
1) it is not possible to set board offset (origin),
2) some problems related with machine coordinates. Seems that chinese mm != conventional mm. Not sure, but may be 2 options possible - they have their own chinese metre bar or I simply got "hot climate version" which expands in higher temperatures. Because real 300mm are equal to machine travel by 299.57mm causing about 0.4 mm error on larger boards.
0204?
Both are previously described in this thread. Both can be solved with 3 lines of code, or a little more...
Anyway, that's what we have. Not so bad overall.
Attached - screenshot from software designed for file import from CAD and description how to proceed.

For software ask in private. Reason is very simple - once Neoden gets it, we will never receive these 2 bug fixes, they will distribute "corrector" instead.
Any comments and ideas are highly appreciated.
btw: CTRL-ALT-DEL starts task manager, RUN -> explorer.exe and seems that we have access to HDD... Any ideas?
