Yes, I can confirm that this solution works. I changed last weekend one of the Y-axis modules by the X-axis one and the “bump” has disappeared.

However, I believe that this issue is only another effect of a bigger problem: **the non-uniformity of the lineal modules working speeds**.

I have opened a new topic to discuss this in its full depth: [Non-uniform lineal modules working speed](https://forum.snapmaker.com/t/non-uniform-lineal-modules-working-speed/10715)
