cooling off for infill

[maker2]

Reading Colorfabb's instructions for printing their PETG filament nGEN

http://ngen.colorfabb.com/how/

it says "Coasting is a nice option included in Simplify. This is the act of stopping the extrusion just before a travel move is triggered, this helps get rid of the pressure in the hot-end and therefor also making a retraction move more effective.

We also like the option of only activating layer cooling for the perimeter lines, the infill is not cooled and therefore should maintain best possible layer adhesion."

I've spent an hour looking for the cooling only perimeters not infill. Can anyone give me a clue?

Try to use it in the "Additional terminal commands for post processing" under Scripts

{REPLACE "; inner perimeter" "M106 S128\n; inner perimeter"}
{REPLACE "; outer perimeter" "M106 S128\n; outer perimeter"}
{REPLACE "; infill" "M106 S0\n; infill"}
{REPLACE "; solid layer" "M106 S0\n; solid layer"}

This will replace every inner, outer or infill with the fanspeed you need for NGEN.

I got this from this topic, it helped me. The only thing I changed is the fan speed to 50% (got a CR-10) , and an extra line for solid layers.

I googled too, this topic was in the top row. Further down there was this solution. Hope somebody will be happy.
