Ships randomly starting to drift

[Ozzmodious]

Ok so lately I have had an issue where after a while, a large ship I have been working on will start to drift. slowly starting to float away at about 1.10/ms while i am building on it in creative mode. I have no idea why. none of the thrusters are over riding nor are any of the gyros. If i cut and paste the ship, it stops moving. and i can work on it again, so I have no idea why its moving like this. anyone got any ideas as to how to keep a large ship from starting to drift?

Hi, share more details on the ship or simply share Steam screenshots, that will help to see your concept.

Rotors and Pistons are not good on ships (better on Ion space ships tho) and will give this kind of problem in Gravity < on planets.

OR > You could publish your Blueprint on the Workshop so the Veterans can try

if you hit he can move on space

[Dan2D3D]

Oh! You have added thrusters on all sides?

Because it will drift away slowly if no thrusters on one side!

sounds like you have a rotor with one block pulling/pushing against another block. this form of clang creates phantom thrust. basically just adjust the rotor so the two block surfaces are not pushing against each other.

I have one Atmos ship with ramp on rotor and it drifts slowly, better if I lock the rotor but still not good in Planet Gravity so I avoid using on planets.

Rotor and Piston are not bad on cars tho!

Edit
Very good on stations!

I dont think publishing it would help since I use so many block mods, mostly just different doors... I love doors. But its just so odd that the ship holds position just fine, then randomly it will just float away. I turned off meteors thinking maybe weapons fire causes it to tilt and shift and not stop, but thats not it. I have nothing "docked" to it with connectors, and i have nothing clamped to it with landing gear. i can cut and paste the ship after it starts drifting, and it holds still again. if I shut off the thrusters while its drifting, it starts going faster, like something is pulling or pushing on it, and its all the thrusters can do to keep it from flying away. I am not using any mass blocks and as far as i know, there are no small objects in or on it to cause issue. I have tried moving it out of an opposing gravity field, no effect. turning its own gravity off, no effect. The ship just starts to tilt and drift for seemingly no reason after maybe... 15 to 20 minutes of building on it. and the only fix i found is to cut and paste it again.

There are no ramps and no rotors on the ship. but a LOT of doors leading to the exterior so there is a lot of decompression and pressurizing that goes on while i build. I have encountered the rotor phantom thrust bug before, and this isnt it. i only use rotors on stations for just that reason.

if it is not caused from rotors then one of the mod block you are using has a larger physics cube around it then what the block square space will allow and it is pushing against another block.

I've had ships in the past with phantom weight which did not exist. so it is possible you did nothing wrong at all and the ship is just bugged. sadly the only way to fix such a problem is to start building a new ship from scratch as the coding for that particular grid has bugged out.

those are your two options now, delete the modded blocks until it stops moving or build an entirely new ship.

Do you have any loose components on the floor?

Loose components or rocks are effected by gravity fields. So they push on your ship and create a mini grav drive. That xan also be a cause of ships slowly drifting.

The cut paste may work to fix because its not taking any loose stuff with you, just the ship. Then when you build for a while and drop some items you create the push force again :)

Sharing to the Workshop was for other Engineers to try to fix it for you but if it got Mods!

1 - It is harder to find the problem when playing with Mods.

2 - When it is not working = Bad concept and I have to redo better (new concept)

Solution :

> select your Save, click "Save as" and change the world name to create a copy.

> Load that copy to do some testing and find the problem

>> Doing so = you will not mess with your original save till you find the problem and be able to fix it.

Herre's what I do with any ship (small or large grid) I'm going to leave stationary for a bit - go into the info tab and change to a station grid. When you're ready to move the ship, change back to a ship grid. Been doing this for a long time now and it works great.
I should point out that I only play solo, private, off line. I don't know if there's any difference in an MP world.

Either convert it to a station or use merge blocks to temporarily attach it to an adjacent station. When finished, grind down the merge blocks.
