    Hopefully those motors will do the job :( Keeping my fingers crossed! The kill switch for the movement will not be underneath but it will be hard to reach. Well yes it's almost underneath and will probably have to use my feet to operate it if necessary... Other kill switch is for the open sim wheel.

    it's going to be more of an 180 than 360 due to space issues :D. And the software side I really don't know at this point, remains to be seen.

    It's alive:cheers but i Wired the third Pot on the wrong pin. So the motors Will not Stop spinning. I do not have Time to correct it today. Hopefully tomorrow. I measured the two Hall sensor and adjusted to 2,5v. Third Pot Is 10 turn 10k Pot adjusted to 5kohm... So all motors should be at Center Position.

    Checked the wiring and everythin Is as it should be, but motors Will snap back and forth Extremely quickly when pot's are Turner few degrees from the Center. Changed the min Max Pot value on the arduino code but it does not help. Third motor Will not changed direction at all with the 10turn Pot.

    please upload a video of your SMC3 utility while while you are moving the motors.

    Only had the arduino up and running. Did not send any commands to arduino. Simtools wasn't running. I was following Racing mat's instructions for initial start up.... I Will try to make a video.

    Edit:
    Checked the wiring again and i can't find any faults, but i measured the 10turn Pot and it was faulty. Now the traction loss motor Works. Slowed down the motors by scaling down the pwm. It seems that the Hall effect pot's aren't working as those should. I might have to get 10k 1/2turn pot's for the seat mover motors.

    It Works :cheersat least when testing with 10kohm pot's. Bad luck with the pot's tough. Ripped two pot's from g25 pedals and it turns out that the other one fuctions intermitently :(.

    I had terrible signal noise so I had to rewire everything. All dir, pwm and pot wires are separated from 24/230V lines. Shielded wires for the pots and ferrites on the lines. Now the signal seems to be smooth. I hope I can start with simtools soon...

    IMG_20170316_201536.jpg Had to install fans to cool the motors. I also changed to SMC3 for better motor controll.
