@dc42 said in 6HC+1LC where connect filament sensor?:

but untested.

Can I use it already, or it needs to be tested and then released?

@dc42 said in Duet3D 6HC - FAN WS7040+Drive - wiring and configuration help:

If your original connection method didn't work then adding a 10K pullup resistor between OUT4_NEG (the pin that I think you are calling OUT4 in your post) and +5V from any IO_OUT connector should fix it. That would avoid having to use up the 5V_PWM pin.

I tried this solution and it also works as expected.
The only drawback is that when you first turn on the machine or restart Duet, the fan goes Max speed and it is really loud.
I will keep it using the OUT_9 5V PWM + OUT4_Tach as final solution.

Thanks for all the help and super quick response from all of you!

@dc42
Thank you! I will keep that in mind, if I need to use OUT9

@jay_s_uk I got it working on OUT9, like you said.

Do you think its because the OUT4 is a higher voltage. Just assuming since it is written specifically 5V PWM for out 9.

@jay_s_uk

I will definitely try this! Thanks!

Hi everyone!

I'm looking for some help on how to wire this fan (WS7040 blower + ws2403dy01v04 drive)
I'm using some information I found online:
[https://resourcewebsite.singoo.cc/15626568631290760/en/pdf/1565593622183/WS2403DY01V04.pdf](link url)

The way I wired was using 24 volts input, straight from the power supply and for PWM I've used the PIN SV, gray wire, also using FG, white wire as tacho
On Duet side, I'm using OUT4 and just using just pins Out4 and Out4.tach.
The config.g, I'm doing this setup:

M950 F1 C"!out4+out4.tach" Q25000
M106 P1 C"Tool Fan" S10 H-1 L0 X255

This setup won't work for some reason. I can't make it to spin. It does work when I use the potentiometer that comes with the drive, so I assume the drive is working.

Thanks!
