Hi folks,

When I adjust the print head fan speed using the console it works fine. But when I start printing something, the fans turn off.

I've attached the gcode. It has a line "M106 S255". When I use the mattercontrol terminal this command starts the fans, but it doesn't seem to when I print.

Any ideas? Does cura not play nice with rostock V3?

The layer fans will only run when layer cooling is active. The layer cooling is controlled by the slicer configuration.
