    Building it was much easier for me than this end of things!! Yup, the manual got me to the point I am now. Hopefully today will be the day it comes alive!! The amount of work put in to develop Simtools is mind boggling. And the support that this community gives to folks is amazing. I hope I can be of help to someone some day also. Thanks to all

    Testing with LFS. smc3 utility working fine. Motors working good. LFS sending signal to virtual axis. smc3 closed. No movement from game. One note, save button for interface settings not working. I can create a preset and load any preset but no save button function. Reloaded LFS, Utility and Simtools. No help. Where do I go now?

    Sometimes I can't see the forest for the trees!!!! I can now begin tuning the 2 DOF. I still haven't figured out how to get the second Arduino to work and drive the traction loss motor. That will be today's project after I go for a few laps!!!! Thanks

    HAPPY HAPPY HAPPY. WOW....................... First ride in the sim!!!! What a HOOT. Why didn't I find out about this 5 years ago!! Now I need to search for the instructions on setting up the second Arduino and get some traction loss happening.

    In terms of SimTools you just set up the Arduino in Interface Settings under the Interface 2 tab, and assign TL as [C<Axis3a>] in the Interface Output Settings.

    You can then configure Axis Settings and Tuning Center.

    There are some handy tips here re TL configuration: https://www.xsimulator.net/community/faq/traction-loss-in-simtools.175/

    And others concerning the refinement of motion profiles: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    Thanks. Got both the Ard's communicating with the 'puter and the utilities to work for both. All 3 motors moving. Now for the axis assignments and tuning center stuff. I purchased Asseto Corsa and will start from scratch with motion profiles. One axis at a time.Wish me luck!!!

    Well I got the rig running on 2DOF + TRACTION LOSS on the 11th. I am just in amazement at the fun and action I am experiencing. One hour into tuning and my 30 day old 300 rs wheel quits working. The #1 button (downshift) will not turn off. Switch clicks fine but it is just on. I packed up the wheel and pedals and sent them back for a refund. Now I sit with a working rig and no controls. Ordered a CSL Elite that won't ship till the 22nd. Just happens to be the day I am getting a hip replacement and I will be out of action for a few weeks. That's the way the cookie crumbles!!!!

    Life is like that sometimes, but at least you have the satisfaction of having crafted your own rig, turning an aspiration into a fully functional reality.

    I hope your hip operation goes well.

    Well I am back in the saddle and have been working on little fixes and tuning the rig. Some days it runs great and other days it is just a POS. Latest problem is about a half second latency from the right 2DOF motor. Not sure if it is a software problem or a motor problem. I am just running surge to isolate the situation. Hit the gas and the motor 1 kicks up and then motor 2 decides to follow along. Same on stopping. Motor 1 goes down then snaps back up on a complete stop. Motor 2 just lags behind. Sure feels strange!! I went into utilities and made sure both motor 1 and 2 were identical. I guess I will change out the motor and gearbox first to see if that is the problem.

    I saw a video from '6 degrees of flight' on YouTube that the Sabertooths were the way to go. I think i will use them this winter on my next project. I will watch your thread here to see how they work out. Thanks

    I used the same arduino for all three. it does 2dof and traction loss too. 1 arduino and I have 3 IBT2 motor controllers. The arduino sketch will do all three (at least for me it did)

    Latency problem update with right motor. I switched motors, downloaded the latest SPS software, and put in a new UNO. Insured the SMC3 was identical for both motors. That didn't fix it. Now the left motor is on axis1A into the # 1 UNO and Motor 1 of the first 2x32. The right motor is on Axis2A into the # 1 UNO and Motor 2 of the first 2x32. So I took the right motor and moved it to Axis3A of the # 2 UNO and Motor 1 of the the second 2x32. Well now the motors are in perfect sync. I hooked up my surge motor to Axis2A of the # 1 UNO and Motor 2 of the first 2x32. It lags. So my problem is a lag in the output of Motor 2 on the 2x32. I sent the 2x32 to Dimension and they tested it and said both channels were responding correctly to signal input. I am baffled.
