Is it possible you are tripping the travel limit? Try the on-screen limit
override button. It has to be reset for each move until the limit is
fixed.

If it IS a limit problem, then you need to change the sense polarity of the
positive limit switches in the .ini file, so it no longer thinks these
switches have been tripped.
