Insert At Layer Change Help

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?

    Pretty sure it can't be done by a post processor. Field replacements only work in the start/end g-code settings for a machine. You could just use an int field and put in a number between 0 and 255 (inclusive) (unless your machine uses 0-1 for fan speed) or as a percentage and multiply that by 2.55 in your post.
