Fans not working - solved

Recommended Posts

I've just noticed that early in my present print on a UM2 only one of the fans was going round. I just pushed my finger onto blades of the other two and gave a slight push of encouragement and now they are all spinning properly. Is this anything to worry about? Should I do something in the way of some sort of maintenance?

This is normal. The default settings for Cura I believe are 100% at 5mm so if you have .2mm layers that's the 25th layer. So first layer is fan at 0%, then 4%, then 8%, and around 20% one or both will start up. By 30% they should be both on.

    • "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.
