A nice 5x7 Super Chromega E followed me home recently. All looks and works very nice. One minor annoyance is that the focus seems a bit tight. At times when adjusting focus, the cam wheels that engage the brass rods slip. I adjusted the tension levers a bit that hold the wheels against the brass rods, but don't want to over tighten. This helped a bit. I was wondering if perhaps the alignment of brass rods was off, and hence causing increased friction. Any guidance on what should be checked and possibly aligned and how would be appreciated. Thanks.
