1DoF or traction loss only

Anyone out there know of anyone who did a traction loss only build? We figure if I’m going to start anywhere it would be with the one type of motion that I feel is most lacking from virtual racing.
Willbe started to draw up some plans and a parts list but it would be great to see someone else’s idea.
I built the OSR F1 style seat last fall, so I’d be looking to mount that to a traction loss plate and then “float” that on another plate. Maybe a lazy Susan bearing to the pivot point and some wheels (skate board?) in the back. I’d think a relatively small motor would be able to push it back and forth.
Thanks.

So I have some of my kit at home now and I've started to put things together for the testing.
I have my arduino uno, IBT-2, a wiper motor, a potentiometer that I had laying about, and a 12V 100W power supply.
I followed the instructions to wire it all up and push the SMC3.ino into the arduino (https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/).
I also followed the SMC3 Windows Utility instructions on setting up and tuning the motor. All good, the motor moves and the pot follows along (if a bit less smooth than desired). I have a new pot coming that should be better suited to this.
I downloaded and installed the Simtools game engine and game manager and LFS. I took LFS out for a run before patching. Then I continued to follow the instructions and the Simtools manual to setup the Game Engine.



Next, I tried to use the Output testing, but I didn't get any movement from the motor.

Same when I tried in LFS.
Looking at the Tuning Data I was seeing numbers and all of them changing in the green Game Data - Input section.
I've been trying a bunch of different tweaks to see if there was something I could figure out but I'm kind of out of ideas.
I looked at this post but it has not helped (https://www.xsimulator.net/communit...ting-communication-problem.16808/#post-225253).
After using the SMC3 Windows utility, is there something that needs to be done to switch that off so the Game Engine takes over?
Is there something wrong in the Interface Settings?
Full discloser, I'm doing this from a Windows 11 PC so maybe there is some "security" setting that needs to be disabled that I don't know about.
Also, as you can see I only have the demo version, but when I was in LFS all the lights switched to blue and the game manager said "game running".
Happy to give more screenshots or details if needed.

Hi. Thanks again for the reply.

I adjusted the interface settings to match your recommendation. I had thought that it needed to be [A<Axis1a>], but can the first A be dropped if there is only 1 axis? Regardless, I've tried it both ways and it doesn't make a difference.


I changed the Axis Assignments to have only Extra1. I had configured others as well to see if I couldn't get some movement out of the Output Testing.


When I turn on the Output Testing I do get the light changing from green to blue in the upper right, a happy chime from windows and the assignment and interface turning blue as well. When I move the Extra1 slider the motor does not move.


In the manual it states, "If your Interface Settings are configured correctly, your interfaces should show they are receiving data and most will come to their center positions and await the next command." I'm not sure where in the tool I would be able to see that it is receiving data. Is that in the tuning center? It does not seem so.

When I use SCM3 (closed while trying to do the output testing with Simtools) the Rx and Tx lights on the Arduino light up/flash. This does not happen with Simtools. This makes me think that there is something not configured correctly in Simtools. I've disabled my Antivirus (AVG) and the Windows firewall (Defender).

Even without the SCM3 utility open or the output testing on, the motor will follow the pot if I give it a twist.

I don't think I'm ready for the TL guide nor the Min/Max tuning yet as I cannot get the motor to move with Simtools. Am I wrong?

For what it’s worth, I tried installing 2.5.1 and that did not help. Then I installed 2.4.1 and everything works. Not sure what that could be but…
Anyway, thanks again for the help.
