No extra fan with Simplify3D and OctoPi

Hi,I installed the mosfet for the extra cooling fan and tested it by Manual Mode in S3D and over the Terminal in OctoPi with the code's: m106 (on) m107 (off) m126 (on) and m127 (off). It worked fine.
Then I create a .gcode file with S3D and then print it with OctoPi. In S3D I have set under Cooling settings, that the fan will start from the 1st layer with 100%.

But it won't start.


Are there some more settings I have to set in S3D or octoPi to get the fan to work while printing?


Thanks for ur help!

I Printed an .x3g file from S3D directly from SD Card. There is the same problem with the fan. So OctoPi can't be the problem.

What version of sailfish are you using? My 2015 FFCP with SF 7.7 works with S3D

I'm using Sailfish 7.7.
