How do I assign a new part cooling fan?

maroonds

@Phaedrux I accidentally shorted my F0 port. That's why I'm having these issues in the first place. Thanks anyways:)

Phaedrux

No no. It doesn't change the physical fan port. Just the fan number you're assigning to it.

C"fan2" refers to the port you're using. F0 makes it the default fan.

maroonds

@Phaedrux Are you sure? Because I updated my config to:
; Fans
M950 F3 C"e1heat"
M106 P3 H1 T35 S1
M950 F0 C"fan2" Q500
M106 P0 I0 C"5015" S0 H-1

; Tools
M563 P0 D0 H1 F0
And the fan still only activates when I type: M106 P2 S255

Are you sure?

No, but I really thought that should work.

What firmware version are you using? Can you post your full config?

@Phaedrux Here's my config: https://pastebin.com/ePVM5nhm
I'm on the latest RR3 firmware.

I'm on the latest RR3 firmware.

Which version specifically?

maroonds

@Phaedrux Board: Duet Maestro 1.0
Firmware: RepRapFirmware for Duet 2 Maestro 3.0 (2020-01-03b3)

In RRF 3.0 for the Maestro, fans 0, 1 and 2 are pre-allocated to "fan0", "fan1" and "fan2". So if you want to use different assignments such as:

M950 F0 C"fan2" Q500

then you need to remove the existing assignment to "fan2" by doing this first:

M950 F2 C"nil"

In RRF 3.01 the default fan assignments have been removed,

Like this? ; Fans
M950 F3 C"e1heat"

M950 F2 C"nil" Q500
M106 P2 I0 C"5015" S0 H-1

; Tools

It's still not working.. I tried upgrading my firmware but I get this error: M997 S0

No, you need to use M950 F2 C"nil" (to free up pin "fan2") and then M950 F0 C"fan2" Q500. Then you can use M106 P0 I0 C"5015" S0 H-1.

You will find that file in the 3.0 release page on github.

Now it's working, thanks!
