I'm about to start a print, but it looks like i was missing this line in my starting GCode:

M106 S[fan_speed_pwm] ; set fan speed

SOLVED.

What's the difference in the gcode output then? The M106 commands had been there before, so how did adding another M106
to the start script change the behaviour?

I didn't look at the output since i didn't care as long as it worked, but ill look now lol

the layer line gcode is exactly the same "M106 SXX" so it must have been defining that variable in the start script?

and/or I also checked the "include thumbnail images" box in the output tab with thumbnail "encoding" for Klipper. not sure if that had any difference. either way its working now!
