falty fan

Recommended Posts

hey so i got my UM2 a few days ago and ive put on about 30 hours of printing so far and i just noticed that the left cooling fan doesnt spin consistently, sometimes itll spin fast, or slow, and its speed seems to constantly fluctuate, whereas the right side fan is at a constant speed all the time.

Does tapping on it help? Mine did that too for sometime. It was kind of loose but then it never did it anymore.

If sometimes it stop then you might have a loose connection too.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
