I have not been able to find in cura how to set speed of an additional fan. ex: M106 P2 S150
Currently I have a find and replace script just to turn on my aux fan at a certain layer.
What I would like to do is to use "insert at layer change" to reference the part fan speed at the start of each layer.
ex: when to insert : before G-code to insert : M106 P2 S{cool_fan_speed}
but when the file is processed the g-code shows as M106 P2 S{cool_fan_speed} not M106 P2 Sxxx
am I missing something or can this not be done?
