Smart Effector separating heatsink fan from LEDs
-
Yeah, currently the slider doesn't change the speed at all. though I don't recall if sliding it all the way to 0 turns it off or if 100 turns it on.
Curious as to the F30000, the wiki says that if you're unable to control the fan, try lowering it. I was thinking that since I currently have F500, which I believe I got from the configurator, that I'd try lowering it first to the "default" 250.
Edit:
This is the Noctua fan I have. -
The frequency range is viable all the way from 10hz to 30000hz. Every fan seems to be a bit different. You can quickly test by using the M106 P0 S1 F250 command in the console, then just change the F parameter and send it again.
You can use the same command to test if the fan is controllable or not as well and bypass the slider.
Some fans may also require a short blip of 100% speed to start reliably from a standstill. Use the B parameter for that. Adding a fraction of a second is usually enough. B0.5 for example.

To do that test if it's speed controllable and bypass the slider, I'd have to change the S parameter when I send the command correct?

@blt3dp Correct

Thanks, I'll test it out.

Yep, that took care of it. I ended up removing the frequency parameter and let it default to 250 and now I can control the fan speed.

Reviving this, I just decoupled the hotend fan from the smart effector so I can have the fan set to thermostatic and be able to separately control the LEDs.
It works perfectly, I can issue M106 P2 S<whatever range> and it works. I've got nothing related to it defined in config.g
I was wondering if there would happen to be a way to put it on DWC as a slider but rename it to LEDs or something other than fan.
Edit: Figured it out, M106 C parameter

Reviving this again. Moving this setup to a Duet 3 and am planning to operate the hotend fan, part fan, and the leds on the smart effector from the Duet 3's 12v regulator. I know the power draw has to be less than 800mA. I know the specs of the fans I'm going to be using, just wanted to make sure the LEDs would still be ok.
From what I know, they're these:
https://www.digikey.com/product-detail/en/cree-inc/CLM3C-WKW-CWBYA153/CLM3C-WKW-CWBYA153CT-ND/61386173 of them at up to 100mA Peak, am I correct in that the 12v regulator on the Duet 3 should handle this?

No where near 3x100Ma.
12V through the series resistor of 140 Ohms current will be about 85mA. It will actually be substantially less because of the three LEDs in series. Guesstimating at the LEDs forward voltage drop, the actual current will be around 18 to 20mA.
So it depends on your other loads; calculate 20mA for the LEDs.

Thanks, I did see that part of the schematic, just wanted to double check and see what i figured was correct.
