I recently bought a new Freedom and stitched a casing for leader grips on the take up and backing leaders. When I load a quilt I have noticed that I get a bit of sag at one side and that the leader grips are not aligned straight with the take up roller. Starting at the left side its straight and then gradually I can see that it drifts away to the point where its a half to three quarters of an inch away from the take up roller. So I think its safe to say that the leader is out of square because the casing is stitched straight all the way along. I'm new to long arm quilting and I "assumed" that the leaders would be square since everything is brand new. My question is, is it standard practice to check for squareness of leaders on a new system? If so, I do wish I had known this in the beginning. I guess I'm going to be taking the casing out and squaring up the leaders. Any input would be welcome for this newbie.
