Migration from Maestro to Duet 2 WiFi
-
@phaedrux yeah, I see those, but it only says VIN or 5V, nothing about external
-
@gnydick it's a jumper. You can either bridged the connection between VIn or 5v, or don't use the jumper and connect your own voltage supply straight to the pin.
Get what I mean?
-
@phaedrux I understand jumpers, what I don't understand is where to connect my own supply.
-
To the center pin.
-
@phaedrux and it can be a single wire from the positive of my 24V power supply?
-
That's right. But if your duet power supply is 24v and you want to power the fans at 24v just use the jumper to connect Vin to vfan.

@phaedrux obviously
But I blew one of my mosfets, I think. It's weird. I can hook up a 24v blower to the AOF and it works fine. I hook it up to one of the other fans on the same rail as the AOF and it just spins slowly, no matter where I put the slider. I hook it up to the other rail (just FAN2) it and runs slowly. I don't understand how it's working at all if the mosfet blew on.Is there possibly a config problem?

@gnydick What does your M106 fan block look like in config.g?
You could try measuring the voltage of the fan pins with a multimeter, but be incredibly careful not to slip and short something.
-
@phaedrux yeah, I've done that before, not going to tempt it.

My guess is as good as yours as to what that ultimately means. Sorry.
