Frame and start Tab Going Crazy

So I am having an issue with my program. The software will home correctly, however, when I attempt to frame or start my project, the machine rockets to the far upper right of its limit and even attempt to go beyond that. I am consistently having to stop it flying across and possibly break my brand new machine. I have attempted to create a new origin for the starting point, however, when I click on start, it flies as well to the upper right corner of the machine limits. I am new to this to say the least, but since downloading the program, I have been able to burn 4 times, since then, I am getting nothing done and am spending hours trying to fix something I can’t seem to find the answer to. I have looked at other threads with similar issues and have attempted those fixes and I am still having the same issue. Can anyone help? T.I.A.
