The Docking Autopilot has a glitch that let him lock up right before the final push from time to time. Switching it off and directly on again normaly solves that and will dock immediately. https://forum.kerbalspaceprogram.com/topic/154834-112x-anatid-robotics-mumech-mechjeb-autopilot-2143-4th-march-2023/page/168/#comment-4247646

Rightclick on the MechJeb Tab and you can drag it around.

The problem is that it only happens sometimes. Most of the time it is working fine and sometimes it simpy stops right before docking. I was docking and undocking several times on diferent dockingports to provoke this behavior For me it looks like the autopilot is locking up before the last push.

For me switching the Docking Autopilot off and on again solved the problem every time, I have seen this behavior in every version of MechJeb so far. It happens sometimes, i can't force it to happen. Here is a Savefile, the ship is the "Docking Trainer S" , Only Mech Jeb and Modulemanager in this install. Hope this helps.

In order to get MechJeb work that way you need Module Manager too

MechJeb2: 2.12.0.0 is for KSP 1.11, at the moment only the Dev Realeases suport KSP 1.12 To enable the Dev versions you have to add the Repository in Ckan under -> Settings ->Ckan Settings -> Repositorys for Metadata ->New.

If you use the Mk2 Clamp-O-Tron, it is broken. It has it's controlpoint facing in the wrong direction, The bug is confirmed, so all we can do is to wait for the next patch.

I used it to fly from Kerbin to Duna. Tested again, and it is working again. Is your install of KSP a clean one?

As far as i can see Module Manager and MechJeb 2 DEV RELEASE 1082 seems to be working fine with KSP 1.12. The warning at the start that MechJeb is made for an older version of KSP, can be ignored.

Just tested with MechJeb 2 - DEV RELEASE 2.10.0.0-1008 , no problems. Edit: Second test with a more Modded install, MechJeb 2 - DEV RELEASE 2.10.0.0-1008, again no problems. Btw. do you have a pilot in your ship? If not, do you have a radioconnection to Kerbin?

Looks like the problem was on my KSP install. Kerbal Engineer Redux (the only mod installed besides Mechjeb and Module Manager of course ) was causing the problems with Mechjeb somehow. After deinstallation of Kerbal Engineer Mechjeb was working fine. I have reinstalled Kerbal Engineer after that and again everything was working fine ( both versions of Mechjeb, normal and latest Dev version tested ) So you can stop chasing ghosts now. And thanks for this great mod, without it KSP would not be the same!

Dev Build 988 seems to be working with 1.10 so far. Landing Guidance, well see my post above.

Can confirm Rendezvous Autopilot working again. Thanks guys, great job

The Rendezvous Autopilot seems to be broken. It creates a maneuvernode, but did not execute it. The Rendezvous planer, or the Maneuver Planner are working fine. The only errormessage in KSP.log i could find is: [MechJeb] Brents method threw a timeout error (supressed). KSP 1.9.1 MechJeb 2 - DEV RELEASE 2.9.2.0-961

#946 fixed the problem, Rendezvous Autopilot is working again.

There are no errors in the log annymore, and the autopilot is now plotting a Hohmann transfer, which is good so far. But the transfer itself is messed up. The autopilot is saying Status: Planinng Hohmann transfer for intercept after -127276.43 phasing orbits and then bringing me into an orbit that is between my old orbit and the target orbit. After that it repeats what it is doing, but is not able to bring me close to my tagget. Sometimes it is plotting orbits below 50 km. If i use the the Maneuver Planer to make a bi-impulsive Hohmann transfer everything works fine.

There Rendezvous Autopilot seems to have a problem plotting a hohmann-transfer. After the planechange it seems to stop, not plotting a . Sometimes it does after a while, sometimes not. Same with the Rendezvous Planer. If i do the hohmann-transfer via the Maneuver Planer and start the Rendezvous Autopilot after it everything ist fine ( start orbit 80 km destination orbit 150 km). A workaround is to use the Maneuver Planer (Change plane to plane of target, bimpulsive hohmann transfer, aleing speed at closest approach.) In the log i get this several times (KSP 1.9, MechJeb 2- DEV-RELEASE 2.9.2.0-943, Kerbal Engineer Redux 1.1.7.1, Module Manager 4.1.3) [ERR 10:00:24.615] MechJeb module MechJebModuleRendezvousAutopilot threw an exception in Drive: System.TimeoutException: Brent's rootfinding method: maximum iterations exceeded at MuMech.Brent.Root (MuMech.BrentFun f, System.Double a, System.Double b, System.Double rtol, System.Double& x, System.Double& y, System.Object o, System.Int32 maxiter, System.Int32 sign) [0x001e3] in <8681954d36844c0e910d375b3cdf5e16>:0 at MuMech.OrbitalManeuverCalculator.DeltaVAndTimeForHohmannTransfer (Orbit o, Orbit target, System.Double UT, System.Double& burnUT) [0x00102] in <8681954d36844c0e910d375b3cdf5e16>:0 at MuMech.MechJebModuleRendezvousAutopilot.Drive (FlightCtrlState s) [0x00650] in <8681954d36844c0e910d375b3cdf5e16>:0 at MuMech.MechJebCore.Drive (FlightCtrlState s) [0x00048] in <8681954d36844c0e910d375b3cdf5e16>:0

Looks like a part from this Mod: Kerbal Engineer Redux

If you are getting oscilations the PID is overshooting and addding more control autority will make it even worse. You should try the opposite. More is not always better.

And it is not needed anny more, thanks!

No, the dev build is shown as only compatible for 1.3.0, so you have to set the Compatible KSP Versions on CKAN to 1.3 under Settings , or it will not show up.

As i said, it is only one option. But it is always a good idea to take a look into a working solution, to see how they manage to fly a plane. Turning a spacecraft is one thing, but turning a plane is a complete different thing. You have to control roll, pitch and yaw at the same time to fly a good turn, and this is the point where Sarbian has problems at the moment. I know Sarbian will solve the problem one way or the other, but it is easier when you can learn from others, instead doing it all from scratch. And i know, to create something like mechjeb is a hell of a job. We can't thank Sarbian enough for his work, without it KSP would not be the same.
