I have had an SR6 for almost two years now, I always kept the L0 up/down axis at 100% because I just thoght more is more, right? Well, I was wrong and I'm so happy I found out. You should experiemnt with less-than-full-stroke-length-limits!! Holy crap is it better!! I have average sized anatomy and the SR6's max stroke lenth more than covers my length. Full strokes can go from the very tip to jammed down hard into my crotch, which doesn't feel as good as you might think. I never really explored limiting the device itself cause I just dismissed that as wasted potential. I use ToySerialControler by @Yoooi and there limits for the stroker so that it scales the moves in a scene to match the range you want to feel in real life. I have found that 5% low end limit and 95% high end limit suddenly feels so outrageously good, it's like I got a new toy, and the level of immersion is massively enhanced. Now, when the girl just slides her lips or pussy over the head of the cock in a small teasing move, that's exactly the move my SR6 is doing to me, and the subtley of it is breathtaking. When she deep throats or thrusts balls deep, the SR6 still presses firmly to the very base, but without being unconfortable. Also, every inch of movement in between is reproduced accurately, and it's smoother becuase the scaling blends values together. I don't limit the other axes because feel like this makes pitching and rolling moves MORE pleasureable, especially with blowjob onaholes that have tongues since the tongue slithers around more relative to the up/down moves and it feels amazing. Another great part is once I get positioned, I can relax and know that I'm not going to pop out, and that really adds to the pleasure, and immersion. Give axis limits a try. Less is more.
