    Hi: I'm using encoders, Kangaroo x2 and Sabertooth 2x32. Live test, Tune worked. Rebooted.
    These are my settings. Can you see where my settings wouldn't allow it to home at half way?

    I do not think it is supposed to center after homing. Instead, it moves to one of the limits (which is at minus something coordinate) and backs off a little to get to zero.

    Thanks for the response. I'm so close to doing laps again!
    It's doing that on com 3 M3
    and Com 5 M1, so I think they are ok. On Com 5 M2 I getting this when I try live speed. Homing Simtools live speed.PNG
    Also when I run Simtools M3 and M1 only hit the limit switch and back off a bit.

    I have DEScribe working and Simtools finds the 3 limit switches on Output Testing, but isn't centering!

    Any ideas?
