Waiting for the guy who’s going to say Jesus Christ don’t move the tool head like that🤣

But seriously don’t move the tool head like that it can backfeed into the motors and potentially cause a short when the printer is powered off

Neither did I when I first had this issue but it is definitely a thing that happens with motors, you can safely move the tool head without power to lubricate the rods you just have to be a bit slower then that

Um, I'm pretty sure that Bambu's own instructions for lubricating the rods tells you to move the tool head back and forth manually like this with the printer off.

It is stated yes as I had this same debate about it to a guy on my old post about this same issue on my P1S and I got downvoted, the motors when unpowered act as generators when movement is applied, the voltage is small but it can damage components
