Honestly if your going to go through all this effort to make this work, and already have a pi, I would suggest instead upgrade the control board and switch to klipper, there have to be guides out there
Comment on Can I plug Nevermore filter where I circled?
chrischryse@lemmy.world 11 months agoIdk what type of connector my printer uses since my fan is different

Powering the fan from gpio pins probably isn’t going to work out well either, they are 3.3v and 5v. Powering the fan from the PSU is going to be similar to powering a pi off it, I believe you should step the voltage down to what each needs, where the fan is 24v I think the pi is 5v. Your PSU is probably 115 or 220 v. For connectors I would expect to have to redo them yourself with micro fit, molex, jst or w/e you want and can get. On some of mine I just did single pin molex on the pins of the white female connector for fan headers, it doesn’t lock but it works if you don’t have a lot of movement.

Seems complicated I might just connect it to and adapter I can plug my 24v laptop charger into

Pi’s are usually 5vs, they won’t drive a 24v fan happily at all.
At that point what you can do is a power relay- like how most bed heaters work. That could be controlled by a pi, but delivers power from a 24v source.

Like I said in my other comment
would it just be better for me to use one of these amazon.com/…/ref=ppx_yo_dt_b_asin_title_o00_s00?i… with a laptop charger?
FuglyDuck@lemmy.world 11 months ago
If the charger is a 24v powesupply, that would work. I would also suggest getting a switch to put in line so you don’t have to keep unplugging it- either a rocker switch or mini toggle.

Not sure how familiar you are with electronic stuff, but the fans I have are 24v and 0.1A my laptop charger outputs up to 6A that shouldn’t be an issue right?
