If you file the screw ends flat and drop a BB in each tube or coupler, this goes away completely.
My machine and threaded rods are square. I found the issue to be slicing as I was trying to find the best retraction. I recently printed a fan setup and have no banding.

To me both machines have the same quality, that is because I have tweaked my Prusa until it printed well. I used this knowledge immediately with the Pegasus. This means they both print the same quality.

However, the setup on the Pegasus is a lot less, you don't have to build motor mounts and multiple layers of plywood to create a frame.
