Fan Speed

Recommended Posts

I've set my fans to come on full at 1mm, then, I while printing, I actually put them on full after the first layer.

I've noticed though that during the print, the fan speed automatically fluctuates down to 50% 80% etc.

You can manually turn it back up to 100%, but obviously I don't want to sit there and baby sit. How do you prevent the fan speed from changing during a print?

Cheers.

That's because cura increases the fan speed gradually for the first layers. If you look at the gcode you'll see a "M106 S127" (the second number is the speed) that changes for each layer in the beginning. This will override the fan setting in the tune menu. I would just change the layer height it comes on at to something lower to go around it.

    • "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.
