    Hi there Sim community,

    like everyone we are trying to integrate Motion Sim with VR and have hit a brick wall!

    We are embarking on a major sim project which we currently have set up in my large workshop in Perth WA.

    Our current goal is to have a system which is able to dynamically track a specified target position on two axes, smoothly and with as little latency as possible - mimicking the movements of a vehicle simulation in real time.

    We currently have a system which utilizes two DORNA servo drives, connected to an iMC3042E ethernet motion card (in communication with a Windows PC).

    At the moment we've been communicating using the provided IMCnet libraries in a custom C# application, which is used to convert the sourced angles into target parametric positional values which are then sent to each axis.So far we've tried using the tracking parameter (mcstrack) to regularly update the target position (mcstgpos), with mixed results.

    In testing this method, the movement from the motor seemed to be uneven and jerky, as well as significantly delayed.

    Next, we were planning on modifying the target velocity (using mcstgvel) as required whenever the source angle changes.

    Although this solution will result in a smoother movement, it does introduce issues with maintaining accuracy. Before exploring this option, we wondered what you recommend as a possible solution for this application.

    Basically, do you have advice on what is the best way to send a continuous stream of positional updates to the motors with as little lag as possible?
