Rope problems

I've downloaded the mentioned machine and I see no problems with it.
Could you start with what you expect the ropes to do?
Then say what the ropes are actually doing for you?
Other than the fact that the ropes will break if you shorten them too much - which is what I'd expect them to do - I can't see any problem either. If you want people to help you out, you need to provide more information.
if I wait for your machine to settle down, I do notice an occasional unsettled bouncing of the ram, but nothing as significant as the video you have shown.

Capitalized letters is considered yelling online and isn't necessary to get help.
