Yes downward ones, they interfere with my camera. Will keep taped then.

Is there any way to disable them in firmware?
Currently I stuck small pieces of tape to them, but maybe there's more elegant way

@kolja Yes passed finger test just fine. Can't feel any heat on sink w Noctua 40x10 from 12v on Duex 5.

Some time ago I was experimenting with fans and forgot to pin 12v on Duex, so powered 12v Noctua from 24v, it worked just fine for about minute or 2 till I realized why it spins much faster. Not sure how long it has to work on 24v till damage occurs, but I think that 15-16v on Noctua will increase air flow without making in louder.

@kolja Thanks a lot. But how you figure out that there's not enough pressure for radiator cooling? I have Noctua 40x10 on 12v cooling v6 on Railcore and yet to see any issues. Neither w 200 PLA nor 280 PC.

@Danal Yes I use exactly the same method now. Wish I could lower RPMs to 70%, this fan is too brutal.

@sungod3k I left it on default sensitivity. I probe at 150H and 60B, so either completely off or on. There's no way to control RPMs from within Duet as far as I see, except manually lowering voltage to ~10v?

30mm fan creates heavy vibration that translates to constant Z probe triggering, so I have to turn in off before calibration.
I tried to reduce its speed to 60-70% by M106 P1 S0.7 or M106 P1 S200 but it stops completely. Is there any other way to make it more printer friendly without replacing with 40mm fan?

@dc42 You mean that trigger value in configurator should be set as 100 instead of 1000 mentioned by OP?

Hello everyone.
I'm new to this, so please excuse my ignorance I may ask dumb questions.

I have Creative3D Elf corexy printer coming in a week and want to pre-configure Duet 2 Ethernet.

That printer comes with Marlin2 32bit board and uses their own developed double Z axis auto leveling.

According to manufacturer BLTouch is not supported on stock board because they use 2 x Zprobes for each axis motor in order to make this fancy auto leveling and there's not extra port for BLTouch.

I'm trying to figure out how to make this auto leveling + BLTouch work with Duet.

I'm looking into Duet's wiring scheme and I see one Z stop port in the midlle of the board, and another Z probe at the bottom.

So I connect BLTouch to Zprobe, but where other 2 stock probes go? Or 2 is max for Duet?
