    Working on a seatbelt tensioner for my 2DOF plus traction loss sim rig. I have 2 servos connected to Arduino Uno and have the interface setup and working while output testing in Simtools V2. My question is can I or should I have different axis assignments for the new interface? My Motion rig is also an Arduino Interface, and I have 4DOF , pitch, roll, surge, sway. Is it possible to have different DOF for the new interface in Simtools V2? Would I want that? I've read other posts, the Manual, and the FAQ on seatbelt tensioners but I cannot tell if there is a way to save Axis assignments for a specific interface. I tried, but they seem to apply to all of the Arduino interfaces. Any input appreciated. Thanks for reading!

    If I understand your question correctly, a separate controller should be initialized independently in Interface Settings, and Axis Assignments should be set according to the intended purpose of the axis.

    Some SimTools settings are global, such as the Tuning Center, but Axis Assignment and associated settings are specific to the controller as defined in the Interface Settings,

    Thanks Noorbeast, but I still do not understand how to save the different axis assignments to just the new interface. When I make any adjustment to Axis assignments, for example changing PITCH to 50% and I click SAVE, it is applied to both interfaces. Here is a picture of my Simtools interfaces and Axis assignments. I'm wondering if I should put the seatbelt tensioners on 2 other axis? Maybe 4a and 5a, and then assign only the DOF and percentages that I want for them? Do you think this would work? Thanks.

    You could either use 4a and 5a as you have suggested, or to keep your belt tensioner separate from your motion rig, use the '(b) Axis Assignments' tab and change your Interface output code to: R<Axis1b>~L<Axis2b>~

    If you use the B axis, you can save different values in the Tuning Center which can be useful for allowing your belts to be tuned differently from your motion rig, so I'd recommend this method.

    Awesome! That's exactly what I was hoping for. I'll give it a shot, thanks!
