Does anyone have a decent manual on how the heck the controller board works. I was able to get the machine to move but it won't move just a little bit, if you tell is to go X neg it goes until it hits the limit, this is the same in all directions. What am I doing wrong. I am just trying to align mirrors at this point. I have it real close in the back right corner but now I want to move it around and check the other corners.
