Part Cooling Fan on Duex5
-
@alexus that looks fine now.
The pin name is correct.
If you send M98 P"config.g" does it report any errors? -
@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 nextM98 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 -
@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?
-
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
-
@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.

@jay_s_uk
if i cange to P1 i ger error
Error in start-up file macro line 103: Fan number 1 not foundassuming 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" M106 P0 S1 H1 ; set value.

Thermostatic control is turned ON for sensor 0 (S0 in M308) H0 -
@alexus said in Part Cooling Fan on Duex5:
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.

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
-
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.
-
@Phaedrux which port is always on? also whats output voltage?
-
The Duet mainboard has 2 always on fans. Voltage depends on what position you have set the fan voltage jumper. Either 5v or VIN.

@Phaedrux
heh yea i just looked up documentation and yes always on worjs so we know fan works lolwell let me try to assign say fan4 port see what happens
-
@Phaedrux
nope fun4 does not work either
-
@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 -
@alexus Can you post your current config.g, in full? I think there's a configuration error. Also what firmware are you using; post the response to M122.

@droftarts
well i kinda gave up and used configuration tool and extracted code related to fan and heater and it started to work majically so i think problem was some where in letter configuration lol
so now it looks like it wokring for fan parts at least
