If that is what your actualy gcode file looks like, it is a problem where S3D is not passing variables to the gcode. So instead of it saying "M126 S255" like the previous version, it is showing "M126 S[fan_speed_pwm]". The variable of "[fan_speed_pwm]" should be turning into "255" when the gcode is generated. There are about 4 threads all talking about the same general issue. Hopefully they are reading these and have a fix on the way. It seems like it would be a pretty obvious fix since you can look directly at the gcode and see if it "is" or "is not" fixed.

So I changed it so that layer one was set to 0% and layer 2 to 100% but that didnt make a difference. I have doublechecked that simplify3d knows I have a replicator 2. Heres how the gcode looks coming out of S3D:
G1 X-8.88 Y-1.062 E0.0677
G1 E-1 F1200
; layer 2, Z = 0.38
M126 S[fan_speed_pwm]
G0 X-4.454 Y-3.479 F9000
G0 Z0.38 F1200
G1 E1 F1200
I honestly dont know gcode well, but when I check older gcode files made from 2.0.1 would say:
M126 S255
So I think the gcode isnt generating correctly
