Problem with fan 4028
In this guide (https://os.ratrig.com/docs/guides/4028/) which i followed i put the fan Nindec Ultraflo with 4 pin in that way. Negative and positive in the first connector and pwm signal(blue wire from the fan) in the last connector.
When i move the slider on dashboard the fan still idle and creates a smoke. I had double check for the polarity and it is correct.
I noticed wich PWM make different in penultimate connector.
Why this is incorrect?

4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.
