I’ve seen lots of post on the forum about the servo jumping. Mine jumps
too, and I wonder if it’s not a software issue. I doubt that so many
servos would be “bad.”
Mine bounces sometimes (not every time) when the servo is lifting the pen during use. I haven’t
paid attention if it does this when the pen is lifted while the stepper
motors move the egg or only when lifting the pen when complete, but like
I said, it seems random.
I have pasted a link to a video to show what happens when I gently drop the pen arm onto the servo horn.
