Fan port for LED works, does not show up in DWC

lapjoint

Hi,

I have connected an LED strip to FAN2 on my Duet 2 Wifi, and I am able to control it (including dimming using PWM) with M106 P2 S<Value>. Everything in my system runs on 24 volts, including the fans and the LEDs. The LEDs supposedly draw about 550 mA, so power-wise I should be ok.

FAN2 does not show up in the web GUI though. I was hoping to get a slider like the one for the part cooling fan, but there is none. Do I need to use M950 to get that? I don't have M950 for the part cooling fan either, though:

M106 P0 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S255 I0 F100 H1 T45 ; set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P2 S0 I0 F500 H-1 ; ADDED: LED strip on FAN2 - copied from FAN0

That's all there is regarding fans. The config was mostly created by the RepRepFirmware config tool.

Do I need to add an M950 to get the fan slider in the GUI?

Thanks and regards
Christoph

Which firmware version are you using, and which version of DWC?

Is there a "Change visibility" link in DWC near to the fan slider(s)?

I am using DWC 2.0.4. M115 says

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.03 ELECTRONICS: Duet WiFi 1.02 or later + DueX2 FIRMWARE_DATE: 2019-06-13b2

The Fan Control part of the GUI just shows FAN0, FAN1 in "fan selection", and the slider with its plus and minus signs.

Thanks for your reply

Both your firmware and DWC versions are a little out of date. Try 2.05.1 firmware and 2.0.7 DWC.

@Phaedrux Ok, will do. Thanks!

@lapjoint naming the fan with C parameter, eg C”LED”, in M106 may make it show up.

Thanks everybody! I upgraded to firmware 2.05.1 and DWC 2.0.7, and now the fan sliders show up and they work.

Kudos to the Duet team. I have never done a firmware upgrade on any device that was more convenient or less scary :-).

Thanks

@droftarts PS. Yeah, I had tried that. Naming the fans made them show up indeed, but the sliders didn't do anything. Upgrading to the current firmware then did the trick.
