    The basic settings for SimTools JRK interfaces look OK.

    So far you have only enabled Surge. Just for now enable the other axis, just at 20%.

    Now can you test the output, so we no SimTools is working OK before the whole 2 computer stuff, like here: http://www.xsimulator.net/simtools-game-engine/#Output-Testing

    Checking or unchecking the orange boxes in the Axis Assignments sets which way the sim moves for each axis.

    Let us know if all that goes OK.

    I tried the Output Test but still no movement. Then I found the problem! Windows had not installed the driver for the Jrk 12v12 TTL ports properly.
    Win XP was still on SP2 and updating to SP3 fixed the problem. The motors are now moving. So for anybody using Windows XP, you need to have Service Pack 3 installed.
    Another issue solved!

    Has anybody come across the issue that one motor is moving less than the other when in game or when doing the DOF Output test in SimTools? I get only very limited movement on one motor when trying those. But if I choose the Axis Output test in SimTools, I get full range on both motors. I had a bit of a look through the forums but couldn't really find an answer...

    So have you set up all of the Axis and if so what are the settings? Initially you just had surge set.

    Still just Surge. I thought I set this up the way I like it before moving onto other forces...
    Surge is still set to 20%. I haven't tried any other forces yet.
    But I will try other forces and see if they behave the same way. I will report back.

    It is correct to setup one axis at a time, but to check the issue you may have please add pitch and roll and check the DOF Output. You can disable them later during setup.

    @GIB SimRacing - Just my 2 cents mate, but I rarely bother with the DOF Output and test my motors using the Axis check, just to make sure they are working and move at the same speeds etc.
    Once you tune a profile you will likely find that the DOF output is better, or as a temp measure, put Surge to 50% and see if the DOF motion is greater, then you know the output is good.

    Me personally, I get all the forces / axis going in the right direction with 30% on all the values.
    Then in the Game Manager I turn down the Master level 10%
    Fire up the tuning centre, start capture, set all values to 0.
    Save settings. Stop Capture.
    Start Capture again and go for a drive in the game you are working with, drive up a few hills / rumble strips / accelerate / brake / sway around. etc.. (Dont crash, as will affect all forces and give higher than normal values)
    Pause game, save settings and then stop the capture.. and then tweak the tuning settings manually (per force if needed)
    I find some of the plugins have quite large initial values that can make movement at 20% barely noticeable.

    Hope that make sense...

    @Archie and @noorbeast - Thanks guys for taking the time and offering your advise. It is much appreciated.:thumbs
    I will do some more testing and configuring tomorrow and let you guys know how it went.

    Well, it's getting there. After re-loading the drivers for the Jrk's as well as re-installing SimTools on the laptop, things seem to be running pretty good now. I reckon that laptop was trying to make things difficult here...o_O To be honest I am not a 100% sure what the issue was. I just put it down to "old laptop" at this stage. We'll see.

    Anyways, I have motion! Be it only basic and not even close to set up properly but still, it is moving. I have had a couple of laps in iRacing using Surge, Roll and Pitch and boy does that make the experience different! The one thing I noticed straight away was that the car felt like it was something rigid and not just an image on the screen (that's the best way I can describe it). A truly amazing feeling that I have never gotten from the sim before.
    Again, only got the forces working and nowhere near set up properly but already I really love it! And I'm sure with time and better setups, it will become even more alive.

    There is still a lot to do before I would call the whole project a success (or though it is really close now). Gotta get all the tactiles working again as well as a few more buttons. And then I really have to clean up the sim room because I can't even remember what the floor looks like in there!!!:oops:

    Now that you have it moving @GIB SimRacing concentrate on sway, surge and heave and get them sorted before worrying about roll or pitch, those you can fiddle with later.

    Yeah right, thanks for the tip @noorbeast . I wasn't quite sure what forces are the best to use so I chose roll and pitch. But I will try sway, and heave instead. I knew that surge was a must but that was it.

    Oh, and thanks @Daguru for backing up what noorbeast said. Having more than one person recommend the same thing always helps inexperienced people. Not that I doubt noorbeast in any way....

    There are some useful settings tips in the FAQs @GIB SimRacing:

    http://www.xsimulator.net/community/faq/axis-assignment-percentage-totals.120/

    http://www.xsimulator.net/community/faq/set-base-tuning-motion-values-in-the-tuning-center.122/

    http://www.xsimulator.net/community/faq/snappy-gear-change-motion.121/

    You may also find that you need a value less than one in the Tuning Center for heave. If so you can manually enter figures such as 0.5, I am pretty sure 0.01 is the lowest you can go.

    If you want you can post a video of your rig that shows both the game and sim movement, that way members can give further suggestions about motion profile refinement.

    ...Haven't had much time to play around with the sim. I spent maybe an hour trying some different settings but that's about it. Still a fair amount of time needed...

    @GIB SimRacing have you had any progress with your build? I am starting my rig next weekend in Salisbury. Would be cool to check yours out at some stage if I can.

    @Nicko321 and @Archie - Sorry for the late reply. I have been away and haven't had a chance to play the sim. I will make sure I have some time this weekend to post pics and a video though.

    I did manage to get it all working and I spent a few minutes setting up the motion for Assetto Corsa.
    Pics and vid will come, stay tuned.

    Again, sorry for the late reply. :oops:
