Today I removed and lubed the Y axis bearings on my MK4 for the first time. Apparently I didn’t ruin anything because it still prints fine.
But I did find one of the tiny balls from one bearing on the desk when I put everything back together. Apparently losing one is not dreadful but I have ordered new bearings.
I also need to find out what the minimalist disassembly steps are to get the bearings out. I don’t feel I was very efficient.
