Fan Speed

[braddock 1]

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.

Check the fan speed max and fan speed min under expert settings in Cura and set them both to 100%

I've already done that.

I've found if you go to the fan speed setting in the printer menu (UM2) and dont exit back out to the main menu, it'll stay on 100%

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.
