If I run a m106 command FAN0 does not turn on however FAN0 led does light up. The voltage at the fan terminal after a m106 s255 is 1.39 and s128 is .93, s0 is .10. I have a 12v power supply and the power select is jumped to vin-vout. I tried vout-12v with the same result.

Hi! You need set your marlin firmware in configuration.h, you can refer to MKS RUMBA32 wiki about FAN output voltage
