Duex5 fan voltage

resh

I have a 12V noctua hotend fan and a 24v parts fan. Is there a jumper on the Duex5 or Duet 2 wifi where I can choose voltage for individual fans? I have a buck converter but I'd rather not have to use it. Thanks for the help.

jay_s_uk

@resh no. its a case of VIN or 5v I think but its not on a per fan basis. You'll have to go the buck route

resh

@jay_s_uk It won't do 12V? I would be bucking the 24V to 12v if I can do that so both fans are on the same voltage.

jay_s_uk

@resh the duex will do 12v but the duet 2 won't. so you could split them that way I suppose

resh

@jay_s_uk So I could do the 12v fan on the duex5 and the 24v fan, (which is VIN) to the duet 2 and I wouldn't need the bucking buck converter?

jay_s_uk

@resh correct

resh

@jay_s_uk I've got these wired. Part fan is in F0 on Duet and hotend fan is in F3 on Duex5. First time dealing with fans but it looks correct to me. I want the hotend fan always on. I can't get hotend fan to turn on.

version 3.3

; Fans
M950 F0 C"fan0" Q500                           ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1                                 ; set fan 0 value. Thermostatic control is turned off

@resh said in Duex5 fan voltage:

M950 F3 C"fan3" Q500 ; create fan 1 on pin fan1 and set its frequency M106 P3 S1 H-1

The M106 should be
M106 P3 S1 H1 T45 assuming H1 is the heater number

This will turn hotend fan on when needed instead of on all the time?

Phaedrux

Yes it will turn on fan3 when heater1 is over 45c.

resh

@phaedrux Thanks for the help. I'm not getting fan3 to turn on when heater1 is over 45c. The part fan is always on so something might be wrong there.

On duet I have the fan jumper on V_fan and VIN, and the part fan(24v) is connected to FAN0. On the duex5 I have the jumper on 12V and the hotend fan(12V) connected to FAN3.

Change fan3 to duex.fan3

No luck with the change. I checked wiring again and it looks good.

Phaedrux

If you send M106 P3 S1 H-1 does the fan turn on?

resh

@phaedrux No, it didn't turn on

Phaedrux

Are you sure you're connected to fan3 on the Duex?

Can you try with a different Duex fan port?

Does that fan work at all?

resh

@phaedrux Changed to F4 but I also checked voltage out of the pins when hotend was above 45 and I'm getting no voltage. It's a brand new board. Also checked the jumper connection and it's good.

Phaedrux

Are you saying it worked on fan4?

resh

@phaedrux Sorry, it did not work on fan4. No voltage out of any fan headers on duex.

dc42

@resh what position do you have the DueX fan voltage selection jumper in? If it's in the 12V position, have you fitted the 12V regulator enable jumper?
