duet 2 ethernet getting power but pins don't
-
hi I have a duet 2 ethernet mainboard, I am using 24 V PSU and 24V fans. I checked the continuity between the PSU and board cables, there is no problem. Board is getting 24V but when I check the pins of fans I can't see any value on the screen of multimeter. How can I fix it, did you have a problem like that?

Which pins exactly are you checking? If they are the controllable pins, have you enabled them with gcode?
Are you having a problem with the fans that would lead you to believe there is something wrong with the voltage?
Since the fans are switched on the negative size, you can check voltage by testing the positive pin and a dedicated ground point.

I might.be off base but did you check the fuses on the board there are 2 of them pull them off the board and check them with a meter both of them...
Also you might have a Moffett ( small circuit board w a heat sink on it ...it is between the bed and the board itself
That's where I'd start to look. You can look at the ongoing termi Al's with you volt meter, if
You do have power there you could have a blown Mosfet -
Is it just the fans? That don't work?

OK then there are two set the ones that are hot all the time and two that need to be controlled thru the g code M106 PO AND M106P1 look in configuration g under fans what does it say there
-
Correction the pug on the right is hot all the time the tree outputs on the left are pwm (variable)
And need to be programed in your config.g -
Assuming that one is your hotend fan
You would have to turn on thermostatic control for that output
The other would be for your part cooling fan and has a dif line of code that sets the speed of the fan depending on the filaments your gonna use. And needs to be variable also.Look under M106
The constant on fan would be used if you had a fan for the duet board as and example... -
thank you for all your responses. It is the fuse! Its melted.
