Uncontrolled spin in orbit with MechJeb 2.0.

[Steve-S]

I put a Munar lander into orbit around Kerbin at 150K to dock with my fueling station. I was using MechJeb to dock but needed to do something else. I turned off the autopilot and logged out, got done what I needed to do, logged back in. When I go to my lander in orbit it's spinning horrible. Could not stop the spin easily. Turned off reaction wheels, turned off SAS and got it stopped with RCS and it started up again w/o torque, w/o SAS and w/o RCS. Tried to use Smart A.S.S. to stop the rotation but no joy. Time accel does stop it but it starts back up again instantly. I'm using Mech Jeb 2.0. Not sure what's going on or how to fix it.

Have you tried turning it off and on again?

Just kidding. It could be that you have set your trim to make your craft spin ( trim is set by holding alt, then using your WASD keys to change the little sliders on the bottom left of the screen). I hope that helps

Awesome. Checked the trim, had not used it so didn't think of it, and it was maxed on all 3 axis. Thanks Trey. You're the Man.

Edit:

Found the cause. I had assigned a joystick to some functions. It had miss-identified the joystick but the axis worked. That joystick was unplugged but the other one, that it used as identifier, was still plugged in. As it's a set of pedals the values were at min. and seemed to set trim on all axis when MechJeb was re-installed. Had to re-trim and then the trim was re-maxed. No mas joystick with KSP until the routines can tell one joystick from another. Not swapping multiple controllers every time I switch games.
