    Hi everyone,

    I've recently finished my PT actuator motion build but im not happy with the performance. its way too smooth, not rigid and harsh like a race car should be. ive played with tuning centre for days and i just cant get it right. also have tried changed the interface settings from 1ms to 10ms with very little difference. i know these actautors are fast and the specs are great, but i also own PRS200 actuators motion system and SCN6 actuators and even the scn6 which has lower specs feel better.

    Ive had multiple people try it and they all say the same thing, the car feels like a boat and floating. when they hop in my scn6 sim they immediately say this is so much better. Even strangers come and say the same, so its not only my sim racing friends.

    Is there somewhere i can turn the smoothing down or off at all? the actuator are great, very quiet and lots of travel but it just doesnt feel good when im racing.

    Please help!

    Come join my Discord if you didn't already, there are many others with PT-ACTUATOR that can assist with the settings needed, to chat or read existing conversations about it:

    Don't know how your actuators are setup outside of Simtools but with my 2dof rig running jrk and wiper motors it all came down to PID tuning. Messing with tuning values increased response to telemetry data but did nothing for crispness of response.
