#Hotend cooling fan not working after installing Sonic Pad.

I have 2 Ender-5 S1 printers and a Sonic pad that I have hooked up to one of them effectively. Since setting up the second one with the Sonic Pad, the hotend cooling fan hasn't been working properly. It doesn't turn on while preheating the printer or during the prints, even when the sonic pad says it is running. The odd part is that it does turn on at other times, for example, during the assisted manual leveling step it was running the entire time. It also turned on once as soon as I stopped a print, but I haven't seen that happen again. It also doesn't work on the stock firmware anymore, which is concerning. Looking for any help I can get.

It seems like there might be an issue with the hotend cooling fan on your second Ender-5 S1 printer. Here are a few troubleshooting steps you can try:

  1. Check the connections: Ensure that the fan is properly connected to the appropriate pins on the motherboard. Double-check all the wiring connections to eliminate any loose connections or cable damage.

  2. Test the fan: You can try connecting the hotend cooling fan directly to a different power source to see if it spins properly. This will help determine if the fan itself is faulty.

  3. Firmware settings: Make sure that the firmware settings for the second printer are correctly configured. Check if there are any specific settings related to the cooling fan that need to be enabled or adjusted.

  4. Firmware update: If the hotend cooling fan doesn't work on the stock firmware, it might be worth considering updating the firmware to the latest version. This could potentially resolve any software-related issues.

  5. Consult manufacturer ...

Can you just plug it into a 12/24v with no control on the board?

#

To test

#

Yeah or another open port on the board that has a fan that is just always on

#

Might be easier

#

Or unplug the fan for the motherboard if that always runs

#

There's a smaller board on the tool head for the fans and heat elements. There's no open ports but I could swap it with the part cooling fan to test it.

#

@haughty rune I did what I wrote above and it works perfectly fine in the port for the part cooling fan.

haughty rune
#

OK, then we know the basics work

#

Are you on stock or Klipper pad now?

quaint yarrow
#

Klipper with the sonic pad

haughty rune
#

OK, plug it back into the port it's supposed to be and tell it to turn on the interface on 100%

#

Then slowly down the percentage speed and see where it stops

#

Wait a sec between each 5% to see if it stays on

#

There's no controls for the hotend fan on the pad, only the part cooling fan. There's just an indicator for when its on. Is there a way to control it by sending commands with the console?

haughty rune
#

Oh sorry I thought it was the part cooling fan we where talking about

#

Yeah I guess if you heat it up to 200c it should turn on

#

The hotend that is 😆

quaint yarrow
#

Yeah I've tried multiple times and it doesn't, not even during prints.

haughty rune
#

Yeah that's bad, it's a miracle the prints worked

#

OK, so we will turn it around, put another fan or the part cooling fan into the slot of the hotend fan and turn on the heat and see if that turns on

#

So we know if it's hard or software going wrong here

quaint yarrow
#

Same thing is happening with a different fan in the port

haughty rune
#

Ok, so the command to turn it on doesn't get sent, or it's too low pwm to turn it on.

#

But what doesn't make sense is that the stock FW now also does this

#

This could mean the board itself is faulty, but then again it sometimes does turn on

#

This doesn't exclude the board itself at fault here, but it's strange

#

Can share your Klipper config?

#

Or does the pad hide that, don't have this hardware

Oh, f there is a tool head board as well ofc, so we don't know if that's broken or the main one

#

Does this look correct?

#

Should be of a ender 3 s1

#

I'd try to get creality support on this one, see if they will send you a new board.

quaint yarrow
#

there's no ports on the main board that are the right size for the fan

#

I'll try Creality support. They sent me a new hotend once so maybe they'll be nice again. The printer is technically out of the 3 month spare parts warranty though.
