Toolboard fan oddity with M106 S0?
-
I just changed over to a duet 3 and a toolboard and rrf3.2. All firmwares are up to date.
OK what I have is a part fan on Toolboard out1 and the hot end fan on Toolboard out2.

Not good! So I started looking at possible reasons but I couldn't see anything in my startup script or the slicer that should cause the fan 0 to turn off. So then I looked at the actual gcode and found that the slicer was throwing in an M106 S0, well that shouldn't cause an issue since the default fan for the M106 gcode is '0' according to the documentation and that is the part fan.
Pnnn Fan number (optional, defaults to 0). (In RRF_3 relates to the fan number created by M950, NOT the fan pin number on the board)
but then I started sending my own gcodes and for whatever reason sending M106 S0 does turn off fan 1, not fan 0. Sending M106 P0 S0 does turn the part fan (P0) off and M106 P1 S0 turns the extruder fan (P1) off.So is there a documentation error, something stupid I am doing in config.g or what that is causing M106 S0 to turn off the wrong fan?

Can you post your entire config as there are some other sections that are also relevant.
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
can you run M92 P"config.g" and post the output
-
He means M98 P"config.g"
-
You may need to add a G4 S1 near the start of config.g because the tool board can take longer to start up than the main board. The G4 command should be earlier than any commands that refer to any device on the tool board, such as your M950 and M106 commands, also earlier than the M584 command.

@jay_s_uk I modified the code in the original post to include all of the config.g
I am in the middle of a print and will try the others after that completes. Thanks

you're defining the wrong fan against you tool.
It should be F0.
You shouldn't be associating thermostatically controlled fans with a tool -
@jay_s_uk Thank you! I don't know how I missed that. I don't even know when that got added, anyway that is it. I haven't finished my print but I will post back after confirming.
That took care of it, thanks again
