Hi. I bought the printer in the subject and after many problems in assembling i have a issue with fans..the two fans didn't work. I tried to start those by repeater host but nothing. I tried in different plug on the mother board, fan1 fan2 fan3 and pwm. But nothing...if i power it with external 12V the fans work properly but not if i try to power by mother board. What i have to do? Regards.

Hi,my friend
1.What you mean about your external voltage?And Where did it come from?
2.About the not working fans,you'd better check the voltage between Pin1 and Pin2 of the posted pic to see if it is 12V.

Hi. Thanks a lot for reply. For external voltage i mean that i fan test with a 12V battery. But there is a command to start the fans? Regards.

No,a command is just needed for the PWM fan.But yours is common fans.So,did you test the voltage i told you?It is 12V if the MOSFET is good.

Hi. I ask to seller and he told me to check jp2. If not connected, to use a cap...
I use a 12v input...
I am confused.
