Part Cooling Fan
-
My part cooling fan has stopped working. There seems to be a failure associated with the PWM Fan0 port that I have that fan connected to. It shows 24.1 volts w/ no load, but w/ the fan attached, voltage drops to 2.6. I attached another fan that I know to be good to it and have the same result. Advise please.

Sounds like a bad connection or a failed MOSFET - although that's a strange failure mode for a MOSFET.
When you set the fan to fully on with a fan connected, is it the positive terminal that isn't at +24V, or the negative terminal that isn't at 0V?
-
Negative terminal is showing 21.3.
-
In that case, my guess is that the Fan0 mosfet has failed.
-
Any type of warranty with these boards?
-
Yes, speak to your supplier.
