Posted · 'Always on' fan for UMO+

Hi,

I want to put a small fan on my printhead to cool the hotend (prevent cloging), for printing materials like bronzefill.

I order a 30mm fan, https://www.conrad.nl/nl/sunon-ha30101v3-0000-a99-axiaalventilator-industrie-12-vdc-594-mh-b-x-h-x-d-30-x-30-x-10-mm-184263.html?sc.ref=Brand%20List

The problem is; I have no idea how to wire it to the pcb. I can't use the LED port because I allready use it.

Can anyone help me out?

There's a 5V fan plug on the board that is what um2 uses to cold the hot area. I use that. There's also another fan plug that was intended to cold the board.

The only way to plug a 12v it's with two in series (not recommend).

Thanks for the help.

Can you show me where to connect it to the board and what to so with the firmware? I have no experience so far with firmware and such.

I would very much appreciate it!

There's no need to change anything on the firmware to draw power from this connections, they are always on.

Just remember to check that you are connecting the +/- on the right spots.

      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
