Wrong FAN configuration on ressurect.g

Cartola

Hello,

I am testing the power failure recovery and it seems to be working well, except by the FANs configuration after calling resurrect-prologue.g. As you can see in the code below, on ressurect-prologue.g it is setting M106 P1 S0.00. However, P1 is the fan for the heatbreak, which is configured as M106 P1 H1 T45 C"Fan Extruder". This way, the print is restarted with the heatbreak off.

Relevant content fromconfig.g:

; Fans
M950 F0 C"fan0" Q500 A"Blower"                     ; Create fan 0 (blower) on pin fan0 and set its frequency
M106 P0 S0 H-1 C"Blower"                           ; Set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 A"Fan Extruder"               ; Create fan 1 (throat) on pin fan1 and set its frequency
M106 P1 H1 T45 C"Fan Extruder"                     ; Set fan 1 value. Thermostatic control is turned on
M950 F2 C"fan2" Q500 A"Filter"                     ; Create fan 2 (filter) on pin fan2 and set its frequency
M106 P2 S0 H-1 C"Filter"                           ; Set fan 1 value. Thermostatic control is turned off

Am I missing something here? Is there any wrong configuration?

Thanks!

@cartola I don't have a resurrect.g so I can't check.

How about if you edit it and set the fanspeed that's appropriate?
Or do you even need that M106 in there at all?

Phaedrux

Firmware version?

Not sure it really matters in this case, but the fan command in config.g for your heatsink fan should have a S1 in it to tell it a speed to use when it turns on at 45c. Maybe it defaults to full speed.

My bad, I forgot to post the version:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2 (2021-01-05)
Duet WiFi Server Version: 1.25

I will try to add a S1 to it. The fan is set to 100% during normal operation, but let see what happens if I add that parameter.

@alankilian This file is generated automatically when the power goes out during during a print. Although I can edit it every time I need, as it is created by the firmware, I want to check how to make it work out of the box.

Can you upload that zip file to the system tab in DWC?

Not sure if the .2 update would make a difference or not. If not, it's probably a bug for @dc42

I will make the 2 tests you suggested today I will return with the results. Thanks for the help!

I did the test where I added the S1 parameter to M106 P1 H1 T45 C"Fan Extruder" ; Set fan 1 value. Thermostatic control is turned on, but it didn't worked.

I uploaded the firmware 3.2.2 and now I cannot connect to DWC. I checked my router and it seems the board cannot connect to the wifi.

Cartola

@phaedrux I could connect to the board and I had the same result. Do you think it is a bug?

New firmware:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2.2 (2021-02-11)
Duet WiFi Server Version: 1.25

Phaedrux

Yes possibly a bug. Will need to have DC42 confirm.

dc42

@cartola, I confirm that this is a bug. It's saving the settings of the thermostatic fans instead of the non-thermostatic ones. The fix will be in 3.3beta3.

Cartola

@dc42 Thanks! Do you want me to open a bug on github or something like that? By your response it seems it is a known bug already, but let me know if I need to do something.

Thank you again for the great work!

Phaedrux

@cartola Thanks for the offer, but in this case I think the fix is already in.

Cartola

@phaedrux cool

Thanks, I think this topic can be closed.

Phaedrux

@cartola Well once beta3 is out you could test it to see if it resolves the issue then close it as solved.

Cartola

@phaedrux Sounds good.

dc42

@cartola, I will mark this as solved. Feel free to revert it if you still think it's still not right in beta 3.
