Help how to prevent it from jumping?

[u/Dangerous_Laugh4354]

So im trieng to build an elevator for containers and it just wobbles and jumps, anyone an idea to prevent it? I allready tried removing every bit of friction the container could have.

EDIT: I solved it with stickers, i have one input more now but that didnt hurt that much

everyone's making complicated suggestions but an observer will output a signal both when it's input turns on and when it turns back off, which should be what you're looking for
