That’s the problem, why did you alter the polarity? That will change the direction of travel.
Before you touch anything in the controller, make a backup of the settings. You are fortunate that you didn’t reset the controller. These are generic controllers, each manufacturer sets them up specifically for the machine, including the number of steps/rotation and MANY other things that you would have to guess at and probably end up going back to your manufacturer before it would ever run properly again.
Back it up!
Are you trying to get it to ‘home’ somewhere other than where it was setup to home?
