OK, well if everything else is smooth, I would first ask what galvos are in your projector. Some galvos have problems making small-step moves accurately. I have several examples in my environment that I can demonstrate by drawing a small rectangle on a bounce mirror from 50 feet away. The number of repeats are another potential candidate. Having long repeats (e.g.15) while projecting wide means the galvos come to a complete stop at a point, repeat that point for a while and then are jerked to the next point to repeat the same thing. Depending on the galvos and PSU, this could cause some wobble. Personally, I'd reduce the repeats down significantly to see how it looks. Finally, I'd do some testing with your optimization settings in LSX. Those ~15 options all mean something and its a good education to test with your galvos at the speed and optical deflection (size) that you wanted to achieve. I'd also ask what projection speed are you using? You may be exceeding the capabilities of the galvos for the 'size' you are attempting to scan. Last, but not least, there may be some issue with the DAC. We don't have a lot of testing with it yet, although I've been happy with the Helios that I have based on my limited usage to date.
Sorry to play 20 questions, but these things are complicated . .
