SOLVED: Duet3: Configured wrong

Danal

Board 0: Duet 3 version v0.6 (MB6HC) Firmware: RepRapFirmware for Duet 3 v0.6 3.0beta11 (2019-10-22b1)
Board 1: Board EXP3HC firmware 3.0beta1 2019-10-27b4
Duet Web Control 2.0.4

I have a Duet 3 expansion board with fans configured as shown below. The thermostatic fans work fine. And the tools show up in DWC, and so forth. However, none of the fans show up in DWC. Is this a bug, or am I missing something in my config?

I don't have my expansion board running yet but try adding S C parameters to the M106's to give them names and see if that helps.

You mean C parameters? S on an M106 is speed.

Yeah I corrected it just after I posted

Danal

Tried it. No change.

Have you tried adding M106 commands for fans 0 and 1?

Yeah I just noticed that you put a second "C" param on the M950 and there aren't any M106 commands for F0 and F1.

@Danal I think it's the missiing M106's that are the problem as others have said. For infor, this works for me:
M950 F0 C"2.out6" Q10; fan 0, part cooling fan frequency 10 hz, connected to expansion board 2 out6 (12v)
M106 P0 S0.0 H-1 C"Print Fan";

Danal

Several folks suggested M106s. Makes sense... That's very likely the fix.

I'm away from the printer right now, I will post when I try that later today (in Texas, GMT +6).

That was a mistake, and caused those two fans to not config at all, which cascaded into the tool not config-ing... thanks for pointing that out!!!

M106 with the C"name" parameter DOES make the fans visible to DWC... with the caveat that it only caused a "change visibility" button to appear in the fan section of DWC, and I had to check a box for each fan to become visible.

So: Yes, M106, with C, is needed. In addition, hit "change visibility".

Also, at the moment, the expansion board MAY have to be reset to pick up certain changes in the M950 M106 combination. Safest is M999, reset button on board, M999 again.

@Danal the main board needs to run config.g again to reconfigure the expansion board with new changes. easiest is a reset but just running config.g again with M98 also works.

Danal

@T3P3Tony Thanks! That's much easier.
