Hi @ConsuelaSabau,
It looks to me like your X axis is inline for both X and B cuts… This would mean that your Y axis is not following the “rapid” all of the way back to point B. Like @TonyNo mentioned and I would tend to agree, this really looks like the current going to your Y axis just isn’t tuned to the right amount.
Can you take a look at the following link and see if it helps?
