Hi, I've been reading this thread for a long time and I noticed that a lot of people, like me, are having problems to identify the best PA in their tests. So I tried to create a similar script that tries to give clearer results. I am no sure if I achieved my goal , but I decided to share it anyway: https://www.thingiverse.com/thing:3442071

All the instructions are in the Thingverse link.

Here is one of my prints using PA from 0 to 3. Yeah, I need to use really high values. I didn't completely understood why but my Capricorn (original) bowden tube is big, so maybe I need to shorten it.

@phaedrux Sounds good.

@phaedrux cool

Thanks, I think this topic can be closed.

@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 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 said in Wrong FAN configuration on ressurect.g:

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip

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 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.

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

@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.

@phaedrux said in Wrong FAN configuration on ressurect.g:

ot 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.

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!

Hi @Phaedrux, I added all the versions "just in case"

I could verify the difference using paper, for sure printing would give me the same result.

For everybody that help me - I removed the Hemera and re-run the mesh. Now I don't see the bad results, only the expected axis reflection. You were right! I will re-draw the BLTouch support for Hemera/Hevo to align with the nozzle in the Y axis, this way, even with some rotation, having the BLtouch aligned won't increase the error. Too bad I will lose some print area on X

I hope to have everything fine and uploaded to Thingverse or somewhere else soon!

Thank you all! I will return once I have the updated version.
