Part Cooling Fan on Duex5

alexus

hey all im trying to setup part cooling fan running off duex5 24V (vin jumpers)
well so far no luck, fan does not even web GUI

what am i doing wrong?

here is config, fan is connected to duex5 fan3 port... maybe names was chnged?

; Fans
; Fan 0 -  print cooling
M950 F0 C"duex.fan3" Q500                             ; create fan 0 on pin fan0 and set its frequency //10.25.2024 - Used to be "fan0"
M106 P0 S1 H0                                    ; set value. Thermostatic control is turned off /S-speed 1==100%
; Fan 1 - ToolHeatsink Cooler
M950 F1 C"fan1" Q500                            ; create fan 1 on pin fan1 and set its frequency
M106 P0 T36 H0                               ; set fan P1 value. Thermostatic control is turned ON for sensor 0 (S0 in M308) H0

; Tools
M563 P0 D0 H0 F0                             ; define tool 0 (asign F0 as part cooling fan.. used to be F-1)
G10 P0 X0 Y0 Z0                               ; set tool 0 axis offsets
G10 P0 R0 S0                                  ; set initial tool 0 active and standby temperatures to 0C

@alexus you've set it to thermostatic with H0. Only none thermostatic fans show up in DWC. Change it to H-1 in M106 for that fan

alexus

@jay_s_uk
some times i wish duet wold be variable name based confir insted of G code, would be much easier to read

so i set like this and no availle... also ins P directive set thermostatioc or not?

M950 F0 C"duex.fan3" Q500                             ; create fan 0 on pin fan0 and set its frequency //10.25.2024 - Used to be "fan0"
M106 P0 S1 H-1

@alexus that looks fine now.
The pin name is correct.
If you send M98 P"config.g" does it report any errors?

alexus

@jay_s_uk
no errors just one waring, i guess tem sensor is off but i assume not related to fan now and will deal with that next

M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 0 predicted maximum temperature at full power is 596°C

jay_s_uk

@alexus that's a normal warning, not an error so nothing to worry about.

So now, is it showing up in DWC but not controllable or is it just not showing up at all?

alexus

@jay_s_uk

handg on... when i select tool i see GUI changes

Tool fan is that's a part cooling fan?

if so i guess it shows up and now i need to test electrical why it does not spin

jay_s_uk

@alexus I've just noticed a mistake on line 7 of your first post. It should be P1 and not P0.

But yes, essentially the tool fan is the part cooling fan of the active tool.

alexus

@jay_s_uk
if i cange to P1 i ger error
Error in start-up file macro line 103: Fan number 1 not found

assuming u meant to figuration like this?

@alexus P0 on line 4, P1 on line 7.

ok so like this and GUI shows "Tool Fan" as name

; Fans
; Fan 0 -  print cooling
M950 F0 C"duex.fan3" Q500                             ; create fan 0 on pin fan0 and set its frequency //10.25.2024 - Used to be "fan0"

; Fan 1 - ToolHeatsink Cooler
M950 F1 C"fan1" Q500                            ; create fan 1 on pin fan1 and set its frequency

@alexus said in Part Cooling Fan on Duex5:

See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Fans_connecting#thermostatically-controlled-fans

The convention is that Fan 0 is the part cooling fan (or tool fan) and Fan 1 is the thermostatic fan for the hot end. Though it actually doesn't matter too much which way around you do it, but most importantly:

Note: thermostatic fans SHOULD NOT be mapped to tools.

Currently, you have Fan 0 (F0) as thermostatic with H1, and Fan 1 (F1) as not thermostatic (H0), and have F0 mapped to your tool:

; Tools
M563 P0 D0 H0 F0 ; define tool 0 (asign F0 as part cooling fan.. used to be F-1)

You initially said you wanted the part cooling fan on the Duex, so I would guess what you actually want is:

; Fans
; Fan 0 -  print cooling
M950 F0 C"duex.fan3" Q500                             ; create fan 0 on pin fan0 and set its frequency //10.25.2024 - Used to be "fan0"
M106 P0 S0 H0                                    ; set value. Thermostatic control is turned off /S-speed 1==100%
; Fan 1 - ToolHeatsink Cooler
M950 F1 C"fan1" Q500                            ; create fan 1 on pin fan1 and set its frequency
M106 P1 T36 H1                               ; set fan P1 value. Thermostatic control is turned ON for sensor 0 (S0 in M308) H0
 
; Tools
M563 P0 D0 H0 F0                             ; define tool 0 (asign F0 as part cooling fan.. used to be F-1)
G10 P0 X0 Y0 Z0                               ; set tool 0 axis offsets
G10 P0 R0 S0                                  ; set initial tool 0 active and standby temperatures to 0C

yea i think thats what i want

alexus

@droftarts

so debuging futher to hardware level now

on GUI ive set fan 40% and VIN shows i have 24V on Duet2 board,....

when i measure voltage on Duex5 Fan3 port i get nothing there while Duex5 VIN has 24v measured, also Fan jumper is set to VIN

what could be wrong here? i tried fan speed 100% and no change

Phaedrux

Have you verified the fan works by connecting it to an always on fan port?

If the fan does work, Ttry a different duex fan port?

If it works there, perhaps the mosfet on the original port is damaged.

alexus

@Phaedrux which port is always on? also whats output voltage?

Phaedrux

The Duet mainboard has 2 always on fans. Voltage depends on what position you have set the fan voltage jumper. Either 5v or VIN.

alexus

@Phaedrux
heh yea i just looked up documentation and yes always on worjs so we know fan works lol

well let me try to assign say fan4 port see what happens

alexus

@Phaedrux
nope fun4 does not work either

alexus

@Phaedrux
interesting observation: when i disconnected tthermistor part cooling starts to spin on duex.fan4 port though speed control does not work. So port should be operable
