well, I set transmission parameters as they are recommended once again
and now it has worked - I could upload and download as well . I do not know
what exactly happened because I had the same before and it worked only one way .. ?? as to the timeout , I left it in 4s.
However , even if I can turn the machine on, do reference points, move with axes in every direction ( I had to set some parameters in AXIAL data window, because sometimes it did not go to + , sometimes to - directions ) I still have a problem to run the machine in Automatic mode. A guy who works with this machine uploaded some working program ... but after pushing a button for auto start - nothing happens . So , I think I'm stuck in some point and do not know what to do now.
