Grooves in x-axis guide rails

Deeper grooves on Y rod

I will contact Carbide 3d support. What will be the consequence of this wear on the linear rod? I assume and fear that I have not done enough maintenance, but what is there to do other than clean? Should the bearings not be sealed and pre packed with grease? Maybe something has gotten onto it… [R0010015-01]

I meant to write X. I have the same issue in the same spot.
