So 4028 doesnt work for me for now so im going for dual 5015 24 v
1 is plugged in the ebb 42 v1.2 fan header. And the other will be plugged in the octopus v1.1
What do I have to put in my printer.cfg to make them both run as the cooling fan. Or can i wire them in parellel on the toolhead board or will this damage my fan header.

oke thanks i willl try this out when i have time.
oke im using 1 pin on my ebb 42 toolhead
and 1 on my main board
so i think i need to something different
you need to specify the toolboard pin
but I haven't tested this so you might need to work on it some more
Yeah this doesnt seem to work
I have no idea wtf im doin wrong
what is the error message? Upload your printer.cfg. Otherwise no one can help you...
