sas, rotation

[Rudolf Meier]

1.4.2

my ships rotate

1) following situation: I got into orbit and my ship starts rotating slowly... but sas can handle this... after 2 orbits sas cannot handle it anymore, but I can still manually work against it... after flying to Minimus and back (just a flyby) the rotation is even bigger and I have problems to handle it manually and after 10 orbits (preparing reentry) the spinning is a huge problem and reentry fails because I cannot control the craft anymore

2) other flight: I did put some Agena-target like stuff into orbit and tried to dock with another ship... it was almost impossible and then I found out... the target is rotating ... after restarting KSP it kept its position and I started the docking again... after a while my sas stopped working partially... it only stopped my rotations in 2 axis and on the third axis only when rotating in one direction but not in the other... a restart of the game helped again here...

no idea what's going on here and I cannot imagine that Kopernicus or Kerbalism (or just custom made parts) can be the reason for that

and I do also have a lot of game crashes... I didn't analyze them for the moment, but I will do that later

does someone else see the rotational problem? some told me that they have it also... but it seems they think that it's related to some mods and I don't think so...

I only had rotational problems when I had my joystick plugged in. It was slightly off center and would spin my craft. Does your SAS show in constant use with the two circular arrows when it is active?

The only other thing I can suggest with out any kind of log is that you have a mod like PersistentRotation running or a mod conflict.

If you post a log, people might be able to help with crashes.

Yes, constantly active and as described very strange, because of the changes over time and because of the fact that I can hold it manually (there is enough power in my reaction wheels) but it doesn't hold it correctly... plus it looses the ability to controll it on a per axis basis...

... I don't want to solve it myself. But ...

If no log, I can only say to check that you have the command module oriented properly and not set to a target. Trying the right click context menu of control from here on a command module.

I don't know if you have MechJeb or any other mods installed that could be causing this. Tough to help.

[Rudolf Meier]

*hmm* ... it is related to trimming... but I'm not sure how at the moment... at least I can reset it with alt-x ... never thought that, because I'm not using this in flight... maybe really a mod conflict, but I'm still searching...

[Mark Kerbin]

Do you have more than one control point on said vessel?

We really need pictures and a step by step recreation to begin helping you out here =P

[Rudolf Meier]

ah yeah... sorry, I forgot to inform you... I'm currently writing a mod that helps me to debug this... (also for the non-un-attached parts) ... I don't expect to see anything from the log files... but, debuggers are always a good starting point and if everything fails, I can still do the non-allowed things...

I'm not really expecting help from official sources... I can only remember one single case in my career where a software company fixed a bug that I had... so you see, I have no confidence in those companies... zero... none... NULL...

[Rudolf Meier]

now that's an interesting case... it was my joystick... but, it was not my connected joystick, it was my dis-connected joystick... restarting the game did not help... I had to start the game and then connect my joystick and... suddendly the problem went away... after re-disconnecting it, it still is stable... seems, that the input position somehow got stuck even though the joystick was disconnected...  ... very strange... I didn't know that's possible

[Barar]

Nice, you found the problem. I had similar issues with my joystick, but it was plugged in. I had unplugged it while I was in game to fix so maybe I did a slightly different sequence.

Was looking at upgrading mine as it has too big of a dead spot for resistance feedback, so if I was not holding it, it would slowly rotate my craft.
