Multiple servos / sliders don't work well together

[hardy rock]

I want to build simple elevator doors, but I can't find a way to have three (or more) mini-servos in sequence to achieve that. The servos never end at their correct position and wiggle all other the x,y and z axis. They should theoretically only be able to move on two axes.
I'd love to have better physics for stacked servos / sliders although this seems like a huge task.

yeah fixing that would require some deep stuff in the physics engine
though I've made a door like that and you can just put each segment on a different slider
just set the earlier sliders target position to like, 0.5x the target position of the furthest out one
might need to have the sliders at different vertical positions to fit them near eachother though
then when placing a door on a slider you'd use the precision mode to make it hover below the slider

and then you run into shenanigans where you can't make a grid fully not-collide with other bricks, so for each door you'd place some micro brick on that grid but a ways away from the elevator, then it would let you make the doors not collide with bricks so they can pass through eachother

Ye, can be annoying, but did you try with the torque and power settings?

also some of the wiggle can be avoided by making the earlier segments heavier with the weight brick that's in the mechanics section
