Ok So I got my new DRO installed on my BP clone. The question I have is that the instructions say to make sure the scale is within .02mmparallel to the axis. The problem with that is when I run my indicator over the body of the scale the needle move in and out all over the place, which is normal and I've experienced on other things, but I got zero on one end and zero at a couple inches from the other end (it won't go all the way to both ends becasue the limit of travel). So I just want to know two things, first since I got zero at two point fairly far away is that good enough for a DRO and second what would the symptoms be if it wasn't aligned correctly? I'm guessing the travel wouldn't be smooth and the distances would be off as the scale would be at a slight angle.
So did I do this correctly or is there some other way of alignment? I followed the instructions.
