I notice the same on v1.8.0

In the meantime, a restart and a reslice seems to always fix the issue

I noticed if you change any speed setting in profile M140 is missing from gcode for layer 2. Reseting profile does not help but switching to another profile helps. I've tested a little on V1.8.1 and on some print settings change M140 is still generated but on some like print speed in 100% it is missing from generated gcode. This really sohud not happen.

And today I found that disabling automatic brim would forgot to set M140 at second layer in 100% of situation I'we tried.

Confirmed. Setting brim to disabled removes M140 from second layer setup. OS v1.8.1. Very weird.

Same happens with 1.9.0. My steps:

1. Set "Other layers" temp and sliced - M140 present in gcode
2. Changed filament cost (just to reproduce, it happens with other settings too) and sliced - M140 disappeared

To make it reappear I've changed temp to new value (different from old one), re-sliced and changed back to value I need. Changing temperature like X (required one) -> Y -> X without re-slicing at Y value doesn't bring back missing M140.

Confirmed, and seems to be brim related as @cbaugher said.

I have the same issue on v2.1dev related https://github.com/SoftFever/OrcaSlicer/issues/4676 Cube.zip

Same problem with Orca 2.0.0 / Windows 11 / gcode flavor: Klipper. I don't use brim. Most of the time the temperature change is done correctly but not always.
