> [@"Bump" in Y-axis](https://forum.snapmaker.com/t/bump-in-y-axis/10017): > > Hi, I finally received my Snapmaker A350 slight_smile After setting it up i noticed that when i run the print calibration, there is a “bump” when the Y axis move. I can both hear and feel it if i put my finger on the base plate / linear module. The bump appear in the same area every time, on the last third of the axis movement. When I turn the machine off and move the axis by hand, it moves completely smooth without any bumps. Anyone got an idea why this bump appear / how to fix? Reach out to support. They will likely tell you to swap a module. About halfway down [here](https://forum.snapmaker.com/t/bump-in-y-axis/10017/44) is Edwin, snapmaker support, with a specific check to do. --- _[View the full topic](https://forum.snapmaker.com/t/y-axis-ginding-noise-and-losing-alignment/14082)._
