Fan Speed

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.
