    Hi all,

    I have just built myself a 2DOF seat mover and am now setting up motion profiles for it (or trying to at least).

    I started by setting up a default profile with pitch and roll, both set at 60% and ran No Limits roller coaster sim. This all works fine and seemed like pretty good movement.

    I then went to set up a profile for Project cars. I looked on the forums and found someone else's profile where they set pitch and roll to 60%, sway and heave to 20%. I replicated this on my setup and it nearly threw me out the chair when I pushed the accelerator :)

    So now I have dropped pitch and roll down to 20%, sway and heave are at 5%. This seems to be much closer.

    So my question is why does everyone else's profiles seem to use high percent numbers but mine needs so little? Is there something I am not setting up correctly? I tried doing the tuning center to capture Min/Max (Although not 100% sure I did it correctly?, are you meant to have the sim and motors on during this or can you do it with motors disabled?)

    Any suggestions as to what I am doing wrong? (if anything).

    Thanks, Matt.

    Hi,

    I actually just found that post and I think I have my answer. When I run the tuning center on project cars to get the Min/Max values, I only got values of around 5 for Pitch and Roll. I assume if I manually increase these values then I can tame the motion down a bit without loosing the resolution of the Axis?

    Will have a play around and see what happens. The Min/Max for No Limits are set to 180 so I guess that is why it is working much better than project cars.

    Thanks, Matt.

    @Croccy - there can also be other factors involved. As @noorbeast notes, a lot depends on the rig, but you also have plain old user preference. Folks running in VR seem to want less motion than those with monitors so that may be another factor.

    But there are also other considerations. There is a "tuning center" dialog that normalizes the response for the output of various sims. Depending on how that is set up it can really attenuate or accentuate the profile percentages you see in some people’s setups. On that same dialog where you set axis percentages there is an option to do basic or advanced profiles where advanced has a return to center function. Depending on how strong that is configured, if it is configured, it can also attenuate the axis percentages. I think there is a smoothing function there too (still learning) that could also attenuate motion, and even how PID settings are set for actuators will matter.

    There’s a lot of factors that come into play but they all have a purpose and function.

    My project cars profile works pretty well, but I just feel it needs dulling down a bit. It's like driving a car with zero suspension :). The slightest bump in the road gives a very digital movement. I will have a play with the min/max settings in tuning center as it seems these can "slow down" the motion.

    Matt.

    Increasing the Tuning Center value softens the motion over a longer axis range and reducing it does the opposite.
