Regular Fan Speed at Layer

Recommended Posts

Hi, i'm using Cura with an BQ Hephestos 2 but the part is not sticking to heatbed. I checked that the problem it was when the colling Fan starts working and i would like to reduce the fan speed or just activate it at 5mm height. So i configured the "Regular Fan speed at Layer" setting, but nothing happens, the fan starts working just after the first layer. What i'm doing wrong? another thing i realized is that i configured 4 slow layers but it starts to work faster after the first layer too. I'm not finding the problem, so i decided to ask you some help. You can find a snapshot of parameters in attached files. Thanks in advance.

If the layers are taking less than 10 seconds to print, it will use the max fan speed. Otherwise it should ramp the fan speed up from 0 to 100% over the first 33 layers.

 

FYI - my personal Cura includes an option to start the fan at a layer > 0 which the standard Cura doesn't provide. The Cura developers rejected the contribution. I can't remember why now, it was so long ago. Anyway, you can find my releases at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

    • "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.
