XL Enclosure fan  

RE: XL Enclosure fan

The connector is a 4 circuit Molex Clickmate, available in prepared cable assemblies. This is the 600mm version. The mating receptacle is only available as a board-mounted device, so the XL Enclosure uses two back-to-back receptacles on the sandwich board to extend the blower cable to the Fan1 port. The blower and filter used in the Advanced Filtration System look to be the same as the ones in theXL enclosure. 

RE: XL Enclosure fan

Does it mean the fan signal/power is provided by the electronics of sandwitch board and is not available directly on the existing boards/connectors? 

Do I need to buy sandwich board to make the fan working?

RE: XL Enclosure fan

Sorry for my confusing post 😔 

The existing sandwich board on your XL provides the signals to power and control the fan. The 'XL Enclosure Splitter' board that comes with the XL enclosure provides a convenient place to disconnect the fan when removing the top part of the enclosure, but doesn't alter the signals. 

RE: XL Enclosure fan

Thank you for the explanation. Is there a link for a wiring diagram? I mean the darf connector pins description resp. connection of fan wires (+, -, signal). 

RE: XL Enclosure fan

Not that I know of. Likely signals would be Ground, 24V, PWM, Tach. but who knows which signal to which pin?

RE:

Hope someone with the already built enclosure can describe the wiring later ...

RE: XL Enclosure fan

I am looking for the same info... Not even sure if the fan is 24V or 5V

RE: XL Enclosure fan

From the picture in the assembly instructions, it looks like 24v.

RE: XL Enclosure fan

Yes, you are right

... but I still need to know what pin is used for, I mean there is a 4 pin connector, i expect to need +and - 24V, tach and PWM, and I need to know what goes where.

RE: XL Enclosure fan

Pusa uses a blower fan from Alveo3D, so the pinout is probably the industry standard. GND-24v-Tach-PWM. Checkin with a meter, the GND pin is the bottom one in the picture, so I've guessed at the others:

RE: XL Enclosure fan

Well, this is the correct answer, I've tried with some 24V 4 wires noctua fan and it went smooth.

Thanks.

RE: XL Enclosure fan

I've had a chat with support and was told there were some temperature limit changes made in the latest firmware; I am getting weird temp errors as the summer starts. They recommended me to switch on the "enclosure" functionality in the printer menu (solution not guaranteed for unoriginal enclosures), switch-on is however not possible as the fan is not spinning. Thanks for your answers.

RE: XL Enclosure fan

I've also experienced temp related problems. After searching, I realized that I was not the only one, and ended up with this, which solved my problems on both of my XL:

Hope this can Help.

RE:

Thank you, I have the same (board fan) already applied. My enclosure is however just a box covering the whole printer, so the darf board/mcu temperatures raise up even with the externally controlled fan. What's strange I am getting temp errors even at quite low temperatures <70C sometimes and nice part is this error cannot be confirmed even after the temp is already ok, so only off/on the printer is helping.

My idea is to switch-on the enclosure functionality, therefore increase temp limits, which will hopefully stop the temp issue, will see.

RE: XL Enclosure fan

Must be a big box!

Anyway I wouldn't do that, as I would expect this solution to give too much heat to a lot of electronic, like power supply or other boards. I would anyway consider to have holes int he box and duct fresh air to the electronic, this would help.

as long as you connect a fan, I guess you'll be able to activate the enclosure abilities, But I don't hink this will help you, as this seems to be a overheat issue, and having enclosure don't change temp limits.

RE: XL Enclosure fan

This might be a consideration as well.
