Duet Toolboard Fan Issue
-
Hello, I'm having an issue with my Duet Toolboard.
I'm using a Duet 3, with Raspberry pi 4 SBC, and the Duet toolboard. The mainboard is on version 3.1.1 and Toolboard is on version 3.1.0.
I've gotten just about everything else working with it, endstop, BLtouch, extruder motor, ect, however the two fans I have plugged in are not working correctly. One is for the hotend heatsink and is thermostatically controlled and the other is a print cooling fan. The hotend fan doesn't turn on at all. Where as the print cooling fan is always on 100%. I've tried a bunch of different changes to my config but can't seem to get this straightened out.
I do get these two messages on startup:
M106: Fan number 0 not found
M950: Pin 20.out2 is not freeNot sure what the issue is. Here is my config.g file.

Found a sorta fix. For the print fan I had the wire in GND and not PWM, rewired and now it works. For the hotend fan I rewired it so its ground goes to to GND on out1, this way it stays on all the time. Not sure why thermostatic control still doesn't seem to work but just a slight annoyance that the hotend fan stays on permanently.

M106 P1 S0.0 L127 X255 H1 T45 ; set fan 0 value. Thermostatic control is turned onTo get thermostatic to work you'll probably need to change S0.0 to S1.0 so that when the temp is reach it turns on.

Gave it a try, doesn't appear to make a difference.

You can remove the S, L and X parameters, they are not needed the way you've set it up. As soon as temperature on H1 hits 45C (set by T45) it turns on 100%. You can set a maximum speed with the X parameter, but yours is maximum anyway. If you set a temperature range eg T45:65, I think it should start at the L parameter, so include that if you set a temp range.

;== Fans ===============================
M950 F0 C"20.out2" ; Creates fan 0 on pin out2 (print cooling fan)
M106 P0 S0 H-1 ; Sets fan 0 to manual controlM950 F1 C"20.out1" ; Creates fan 1 on pin out1 (hotend cooling fan)
M106 P1 T50 H1 ; Sets fan 1 to thermostatic controlI have the same setup (Duet3/RPi and toolboard). Here is my config that is working as it should. The only difference I see is that F0 is set to the print cooling fan and F1 is set to the hotend cooling fan.
You mentioned your BLtouch is working.. is it v3.1? I'm curious if it self-tests at start up? I have a workaround for this if not..
-
I believe the BLtouch is 3.1. It doesn't self test and actually is giving me an error led(slow red blink). I double checked the wiring and it doesn't seem to be an issue so I'm not sure whats causing it. If you have a fix I'm all ears.
-
@vishiano here you go.. I'd love to know if this works for you as well!

@oozeBot Thanks I'll give this a shot after my print is done
