How to address Duex5 connectors?
-
Hi *,
I still struggle with my fan setup at my Duet2 with a Duex5. I want to connect the tool fan to the Duex5 but I have some issues to find the information how I need to address the ports on it.
I have this configuration:
M950 F3 C"duex.fan3" Q500 M106 P3 S0 H-1 This seem not to work, not on the first and not on the 3rd connector on the Duex.
M950 F3 C"fan3" Q500
Did not work, too.
Is there a documentation somewhere how I can "talk" to the Duex and how the "names" of all of the connectors are?
FW 3.1.1 since some minutes.
Cheers, Chriss

The pin names are listed at https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet. Use M115 to check that the DueX has been found by the firmware.

Jep, the Duex is known, the (still) working BLTouch indicates that as well as:
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later + DueX5 FIRMWARE_DATE: 2020-05-19b2
This "fan problem" starts to drive me nuts. First the problem that I do not get it working on Fan1, now not even on Fan3. I think that I have no luck here.

Do you have a jumper on the fan voltage selection pins? IIRC, you must have one fitted on one of the selections in order for the fan pins to be energised.
-
Very good point indeed. Yes, I have a jumper to get 12V out.
The idea is to have 12V out of the Duex while the other fans on the Duet2 work with the 24V. So I can get rid of the bug-down.

Did you also fit a jumper across the 12V_EN pins to enable 12 V generation?
-
Most likely not. The existence of that jumper is now to me, to be honest.
And I can not find it one the Duet or the Duex, do you have a hint, please?
Cheers, Chriss

@Chriss It's on the duex. See here:

Thanks... I was starring to the picture since nearly one hour, I was not able to identify the jumper. The "INT 12V EN" did not make it for me.
Anyhow, the Fan is spinning now! I will wire it up correctly and bind that fan as the hot-end fan. That should be everything for now. The rest is tuning "only".
