My X-carve was out of square and had all kinds of problems that I’m fixing, but I noticed this stutter from one servo when pulling the gantry “a bit faster” along the Y while powered off. The right side noticeably jumps when doing this.
What’s more, it that servo seems to “react” by sounding/vibrating even when pulling along X-axis, see video #2.
Is this normal / expected behaviour? If not, what could it be?
I’m afraid that these “jumps” might be the reason why I sometimes get catastrophic failures (diverting off track).
