Good day,

This is my first post in the forum so sorry if things aren't looking well arranged.

I use prusaslicer for my ender 3 and a new direct drive system required me to use a post processing script at the before layer change. The script slowly increases the fanspeed from 75% up to 100% in incements of 10, except for layer 4, to keep the hotend temp from going below cold extruding. I got the help from this page for the script.

{if layer_num == 1 and min_fan_speed[0] < 255}M106 S191.25{endif}
{if layer_num == 2 and min_fan_speed[0] < 255}M106 S216.75{endif}
{if layer_num == 3 and min_fan_speed[0] < 255}M106 S242.25{endif}
{if layer_num == 4 and min_fan_speed[0] < 255}M106 S255{endif}

The problem comes in the second part. I am using Complete Individual Objects and the script doesn't work on the gcode of the second object. I was wondering if it is possible to get the layer height value instead of using layer_num or if some of you guys have a better idea on how to approach this then I am very open to suggestions and criticizim.

I'm using this All metal direct drive it says not to use a silicone sock but I ended up using it to help with the PID.
