Assigning multiple cooler fans

Pertti

Hi!
I´m wondering where the cooler fans are assigned to tools. I have a 5 tool toolchanger . Part cooling fans are assigned in the Tools section but can´t find the cooler fans. They work, however.
I have possibly ruined fans from the duet2 wifi board, is it possible to power them from extra heaters I have in duex 5?

@pertti Not exactly sure what your question is but part cooling fans are assigned to tools and hot end cooling fans are assigned to heaters (which are then assigned to tools). So hot end cooling fans are indirectly assigned to tools because they are usually controlled thermostatically by the heater that has been assigned to a particular tool. Does that help?

@deckingman

I can not see any fans here in the "Heaters" section.

I prefer to have my hotend fan and part cool fan for each tool separated out like this for example.

Fans 0 (which is misnamed '10' in the last M106 command), 2, 4, 6 and 8 are all set as controllable fans, and are mapped to tools T1, T2, T3, T4 and T5 respectively.
Fans 1, 3, 5, 7 and 9 are thermostatically controlled, and should not be mapped to a tool. They are controlled by the temperature of the heater, and are all set to come on at 70°C.

Thanks, I need to study my g-codes better.

Now I got the idea, thanks.
