    Manual mode
    Is it fast enough?

    Sounds too noisy in video, in real live it sounds different

    While you can use 3, I find it easier to use 2 so that I can place them closer to my driver

    So, there is a problem - everything is fine and smooth in SMC3 utility, but in SimTools something goes wrong:

    1. After launching Simtools all motors going lower simultaneously - about 40% of all height
    2. In Output Testing everything works, but jerking a lot

    For language - Simtools and LiveForSpeed works with motion, but jerking.
    I will try to change language, ok )

    New question - there is a very little movements in LFS - is it ok ? About 10-15% of rig's ability

    In Output Testing it works for whole range

    Update: in rally-cross it is ok ))))

    Axis allocation is only part of refining a motion profile, you also need to first capture then refine the Tuning Center values, see the motion profile tuning tips in the FAQs, and take note of first doing one axis at a a time, then combine and refine: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    That has been a pesky Windows rather than SimTools bug, that only seems to affect some computers in specific circumstances, and it has been difficult to pin down why, but at least it is a simple fix and I very much look forward to seeing your rig in action.
