My Ultimaker S5 fan was running rough so I tackled replacing it myself. The cable for the fan was slightly thicker gage, but other than that I felt like the installation went well. However, after one successful print, I now keep getting bed leveling errors even after repeated manual leveling. I'm lost as to how to tackle this, I simply don't understand how the leveling sensor works and how my install could have messed it up. When running the sensor test the number fluctuate from 10 to 200+. Related but also unrelated: are there shops in the California Bay Area that specialize in maintenance/repairs like this? Yoni

I'll try a print core clean. I am using PLA, fresh roll.

I've been printing a big project, and have had my Ultimaker running almost daily since Christmas. While my first layers have not been as nice as they once were, things were always ok and consistent. Since a few weeks ago things have really started to degrade. I've been using the same filament, so I don't think that is the issue. I updated my Ultimaker after not having done that for ages around the same time, but that could be a coincidence. I've manually leveled the bed, which didn't really seem to help. Any thoughts?
