Seems that this unlucky user is describing the same bed motion issues (bump/clunk) I started out with before the firmware update, which made it even worse:

> 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?

Though I was never even able to do a first print due to additional bed heating and lost controller connection issues.
