DueX Fan 8 not powering on.
-
Running am E3D toolchanger using Due 2 hardware.
Everything is working except, Fan 8 will not power on.
M106 P8 S255 is not producing 24v on the connector.
Any tips on debugging this?cheers,

All other fans 2 thru 6 work as expected.
I have tried multiple fans and have monitored the pins with a voltmeter. -

Maybe see if you can measure the gate to see if it gets a signal to turn on or not? Red probe on one of the pads in green circles and black probe on ground:
(Do be careful to not short anything while measuring!)

@bearer Thanks. I'll check in the morning.

Seems to only be TR11 and the I2C expander U8 involved, so if you have no gate signal on TR11 it could be U8 failing.
