Duex fan8 port work weird
i connect my small Dc Relay for controling led light in my printer. And when i send
M42 P7 S1
then voltage is 1.69V and when i send S0 then voltage is almost 5V
but when i connect my relay he won't switch, what can be wrong?
and this is my Config code for pin on Duex
;LED LIGHT SYSTEM M950 P7 C"duex.fan8"

it's nothing big just one small 5Vdc relay connected directly to fan8 output
and then this relay control 12v DC led light
when i change to Fan3 there work's normaly
that is how connected:
and to confirm this same wiring works when connected to fan 3? which version of the Duex5?
There is no difference in the design between fan 3 and fan 8:
Please report the voltage measures on Fan 3- and fan8- with out the relay connected, relative to ground, both with the output set on (M42 P7 S1) and with it set off (M42 P7 S0). they try the relay connected, and test again.
Yes same wiring on Fan3 works as should
