Cant get the extruder fan to work

[sjoerd 0]

I installed Cura and updated the firm ware.

It al works great and the print quality definitely improved.

But I just cant get the extruder fan to work. It should switch on the first layer, I enabled it in Cura.

But nothing, also no way to test it in printrun?

Before in ReplicatorG the fan worked.

Any tips on what to do? I'm out of ideas.

By default Cura switches on the Fan on the 2nd layer, not on the first one. This is because a hot first layer sticks better to the tape then a layer which is actively cooled. (And thus improving the success rate of prints)

The layer on which the fan is enabled can be adjusted in the expert settings.

Hi Daid,

Thanks for your reply. I'm aware of the expert settings.

The first layer is called zero, the fan should work on the first layer after base layer (zero).

Not once after installing Cura the fan worked. Build lots of parts without fan now.
