There is a problem where the servo can twitch. There are a couple of things that can be done about that. But the movement you have is much more than a twitch. I haven't seen that much movement before.

FWIW, I hesitate to post this as it makes no sense as to why it solved the same problem but here it is. I used the same microswitch you have as it is the recommended switch and had the same movement as you except it was downward instead of up. Mine moved down probably because with my servo I had to use 10 as the down position and 100 as up which is backward from what is generally used for some reason. I went through two of the recommended switches due to very unreliable bed leveling behavior, I had to watch it like a hawk. I finally used the z switch that came with the makerfarm ( the one with an arm ) and after many prints I have had perfect reliable auto bed leveling and no movement like yours (knock on wood) during the print. With the recommended switch I had to unplug the servo after bed leveling to stop the movement. No more! Like I said - FWIW.

I've been waiting for this to come up here, had this problem last Summer. No one on any of the forums I frequent had a solution, several diagnosed it as RF interference, but none of their suggestions fixed it. I limped by for a month until it caused a particularly catastrophic print failure (ripped the probe off and almost started a fire). After weeks of Googling I still couldn't find any answers, but then I located this post. That is your answer, ABL has worked like a dream ever since. If it does work for you, be sure to thank jamesdanielv; that's the only real solution to this problem I've ever seen.

What worked for me: Getting rid of the towerpro servo and getting a better quality 9G servo, and rearranging the wires to be differently bundled together.

My servo has a little occasional twitch too, but my servo arm is shorter than yours so the twitch doesn't seem to great. I'll follow the post.

Hexatronics HXT 900 here. looks the same as the towerpro but holds up much better. If buying again I would go for one with metal gears.
