The Z-axis on my printer started making a noise like sand grinding when the table moved. I thought I could disassemble the axis, clean it, and refresh the lubricant. It turned out there were ball bearings inside that an ordinary person can no longer reassemble in the same order. So now I'm waiting for a new Elegoo Saturn 4 Ultra within a week, and I'll fix this one eventually and find a use for it.
