    Quick question. Once you have the 2dof installed, does the seat move and pivot all the time or can you lock it into position when not using the actuators? I'd like to use this for other sims that don't support 2dof and have a static seat for those. Thanks!

    You have to check if the actuators you intend to use are irreversible or not.

    - many wipers are not but I have seen people adding a blocking system (a simple wedge or chock)
    - smolka nidec wiper I used, are irreversible so the playseat stay still even unpowered

    - I don't know about SCN5 or 6...

    winches do not need a blocking system as well (I do not want to push winches but want to be informative :) )

    depends on motors used. This is if you used the JRKS
    25:1 tend to move with power off, so using them to hold still is a command line change in interface. What I do is start a game so the seat props up, then exit the game and game engine tells the boards to keep the power to the motors to hold them.
    Same with wipers
    50:1 , 60:1 usually have enough gearbox holding force when the motors have no power to hold it steady.
    SCN products, dunno, maybe a command line change in game engine would set them to hold.

    I confirmed a gear box 60: 1 with motors type ZYT90, the engines do not move off power. On the other hand, in the case of a use of a JRK card, for learning, it is necessary to disassemble the engine to be positioned manually on the max and min value. @Nick Moxley good option :thumbs

    No need to disassemble. I used this method with my 50:1 gearboxes :
    Just click on "Reset to full range" in "Feedback" tab and then use the slider to manually adjust target to the max and min position in "Input" tab. Works fine and is much less restrictive !

    I undid the nuts holding the pots and in the graph, using a black texta, I moved the pot till I found max and min, marked it, then did a learn and that set it up. Then I fine tuned the feedback manually in utility

    I remember using similar trick inside Simtools to hold my motors centered, I think I've used Output Testing and then DOF test, once started it centers the motors and I just didn't move any sliders. Then I've started a game. I don't remember exactly, I didn't play with it almost half year ago, but it was definitely through Simtools.

    Thanks a lot guys! I wasn't sure about reversible or irreversible but now I know. Thanks!
