Fans not working - solved

Recommended Posts

Posted · Fans not working - solved

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?

Fans can have a slightly different starting voltage, that is completely normal. 1 Printhead Fan of my ultimaker starts at 20% the other at 25%. The Voltage needed to keep the Fan spinning is always lower than the starting voltage.

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.
