Some Cura Settings not Making it into the G Code File

[diego642 0]

Printing with PETG and wanted to turn off the cooling fan for first two layers.   I applied the settings to do that, ran the slicer but the GCODE did not contain the commands to turn off the fan and then back on again at layer 2.   Please advise.   thanks

Lines 35-36:

;LAYER:0
M107

The gcode output uses zero based counting for the layers, so 0 is the first one, and M107 is the command for "turn fans off". This is the fan being turned off for the first layer.

 

Lines 1892-1893:

;LAYER:1
M106 S255

M106 is the command for "change fan speed". This is your fan speed being set to 100% on the second layer.
