Hello,
Since updating Simhub to v7 my pwm fans no longer works.
I created a pcb with fan headers and a arduino micro which is capable of controlling 4 fans. Each fan have their own 12v from a dc adapter.
This solution worked great and was setup by using the Simhubs arduino setup tool using the Shakeit PWM Outputs and the Arduino Micro as board.
Then I would go to ShakeIT motors and turn on Speed when testing in simhub the fan would kick on at 67%, fans are Noctua NF-A14 iPPC-3000 PWM
Tried to rerun the arduino setup tool, and it sees the micro which has 4 motors, however when testing using speed nothing happens.
This are the current settings in V7: https://imgur.com/a/JapYm2e
Hi !
Have you tried to push the global gain ? I see it's still on the default 50% but you said your fans would kick at 67% which is not possible to reach with a 50% global volume : 
Let me know,
Nicolas
Thanks, this was probably the problem, when I use test now on the Motors Output it starts spinning for a second.
Is the test now button meant to only test it for 1 second? tried to mouseclick and hold it but that does not seem to test it for longer.
