    Is there anyone else effectively using the "3DOF Rotating" Rig setup with FlyPT Mover? I'd be interested in seeing someone else's configuration for comparison.

    if Maybe there is a bug in this configuration?

    Could someone take my rig values who know what they are doing and see if you get the same limts?

    Ah Ok then yes your numbers are making sense. I see where you'd have some binding on the bottom side past 40deg, but looks like you could extend the top travel angle to 80deg to squeeze out a bit more motion. So try setting range to 60 and middle to 20.

    This will get you 31.6 max heave and 9 max pitch. But since you cant do any heave when its at max roll and vice-versa, thats why i suggest setting each to half, so your safe limits would be 15 heave and 4.5deg pitch/roll. So you weren't far off.

    also add LOGISTIC(VALUE;15;1) and LOGISTIC(VALUE;4.5;1) to the pose filtering, this will limit the values by approaching them smoothly and not going over, you can play with the 1 value to soften the curve.

    using those values I still get an out of range with heave when at max pitch/roll. I have to reduce pitch/roll to 2.9 in order to prevent that.

    ...or I can reduce heave to 7, that also eliminates the out of range condition, or 10 and 4... etc...

    your pose ranges are still at 100 & 10. and you have 15 in the roll/pitch logistic, set it to 4.5

    I just duplicated it here in my mover to try out, youll still get a over limit when all 3 axes sliders are maxxed as you have them, but are unlikely to hit that in a game.

    like this? (Updated pose ranges)

    yep! thats it.

    You could also try making a new pose using 'basic pose from motion'
    go thru the tabs on top, disable sway, surge, and yaw. set the limits to 15 & 4.5 on heave, roll, pitch there also. adjust the sliders a bit and then theres a button to convert to advanced pose. it should look like you have it set up now, but have all the filtering formulas filled out. or you could just keep it as a basic pose if that's easier to work with for you.

    Thank you so much for your help! I'll try as you suggest as well...

    One more question before I try and hook up to the actual rig again.

    I have "swap direction" checked for all 3 motors because the direction of the motor levers are all towards the center of the chair... I assume that's right?

    Also how do I knw whether "output swap swapped" should be checked or not?

    add a 3d viewer and make sure it looks like your rig, youll see the cranks flip as you click the swap checkboxes

    is moving the following pose slider to the RIGHT meant to:

    - Heave -> Up
    - Pitch -> Front of chair Up
    - Roll -> Right side of chair down, left side up

    yep those are correct. you can look at the 3dviewer as you slide them

    Thank you, time to start the DCS Plug in and watch the viewer without the rig.

    Should I also try the rig using the pose sliders without the game at this point?

    I started DCS and the plugin to provide the data. I was pretty easily able to get out of range condition by performing air combat maneuvers (no out of range conditions occurred with only one DOF on at a time). I also noticed that the sliders reached their extremes fairly quickly. I addressed both of these by reducing the input gain from 1.00 all the way down to 0.1. Is this the right approach?

    yep, thats it! and then if needed adjust the gain on the output side. i suggest tuning one axis at a time. put all except heave on manual & click the '0' to zero them out if they moved. then play the game, put it through some heave moves and adjust. repeat with pitch & roll. then do surge, and sway last (they mix with pitch and roll and can possibly add up to more than 4.5) you can ignore yaw and leave the manual box checked. also you can put 0 in the sway & sure outputs formulas, only the input value is sent down to the roll and pitch mixes
