    This is my first 2dof compact seat mover, and both scruck and DMax's post/videos gave me confident of making one myself.

    I tried it with SMC3, Simtools and AC, the seat's moving, however acting kinda strange.
    In first video, both motor can move smoothly and linearly.


    However, when i test the motors in simtools, the motors aren’t moving linearly, it seems like there is a “steep curve” that pull the seat gradually when the position exceed -2 to -3. Both dof mode and axis mode have the same problem.

    What’s wrong?
