3.0 Heater/Fan configuration
-
The tool fan slider will control the fan of the currently selected tool.

@phaedrux FAN2 is the issue. That's the fan on the hot end. How do I prevent that from showing up on DWC? It should only be temperature controlled from the extruder heater.
-
Is you DWC also updated to 3.2.2?

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
M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency
M106 P2 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned onI can only remember darkly, but I think RRF3 once had a problem when the channels are not filled in ascending order.
I would suggest to rename the 2nd fan to F1 and channel to P1(UTC+1)

That would make more sense. Fan1 is the recommended port for heatsink fan.

@phaedrux I did not take separate action to update DWC - just dropped the big firmware zip in the system folder. If DWC requires a separate update, I will do that.

I did not wire the machine. Will poke my head in the control box to confirm how things are wired and if I might need to switch a couple cables. -

Change the config toM950 F1 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P1 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned on -

Normally uploading the full zip should update everything, but if you are using a very old version it might not get picked up I guess.
You can try uploading the DWC zip file by itself and if that doesn't work, use that zip file to replace the contents of the /www folder on the SD card manually.

I'm not exactly sure what triggers the change, but when I went to run a part, the hot-end fan doesn't start up - but in the Dashboard Fan2 appears, and the slider appears to override the thermostatic control and the fan doesn't run.
By "run a part", do you mean run a print job from SD card? If so, then perhaps something in the print job is reconfiguring the fan - in which case, please share the print file.

I really appreciate all the help.
I changed the can lines per @DIY-O-Sphere toM950 F1 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P1 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned onFunctioning properly and not showing up on the dashboard slider.
The Z-Probe on this machine is accelerometer-based and that's a little flaky, but doesn't seem to be software related.Up and running now, so 'til next time ...
