Thanks for links. These pumps with integrated tanks are easier to install.
Do you know if the Yosoo has a brushless motor, like the SC-300T? Is it possible to under-volt them, to slow them down?
-
@fma i connected them on the fan connectors. I use the pwm at 60% and both pumps work great. But i can't tell if the motor is brushed or brushless
-
Thanks! The SC-300T is brushless, as written on the pump body.
-
For the SC-300T, what is the operating temperature ?
I didn't find it. -
@nuramori Where did you source your self-sealing valves you've got installed on your liquid lines? They look like they would be quite helpful if you ever needed to do hotend maintenance etc.
-
@tech-raton I noticed it looks like you are running a silicone hose over some ptfe / similar tube into the quick disconnect fittings. Have you had any leakages or spills from the overlapping union?
-
Re: watercooled hotends. One of the most simple design is this. Not sure if it was long term tested, but quite inspiriring.

@lael The self sealing valves look like these https://www.ebay.co.uk/itm/174905154309?hash=item28b928db05:g:KZkAAOSwv91hI4tk. I bought the 6mm version but be warned, one of them leaked!!
I also had some leaks after attaching silicone hose to rigid "non barbed" tubing so I use clips (the spring type).

If you are looking for high quality quick disconnects I can highly recommend the ones from Koolance. Being full metal, they are quite heavy which might be an important factor for some. They also are not exactly cheap but they do work wonders, have disconnect leakage in the order of a couple little drops and have never failed me.
I have a set of QD3 series in my machine but they do offer others as well. https://koolance.com/help-quick-disconnect-shutoff-couplings

@nxt-1 Thanks for the recommendation - I'll take a look at them.

@nuramori Really nice setup! Is the Nimble a sidewinder or a V3 ?

They are Colder medical quick disconnects that are dripless.

@generisi that’s an old build. I ended up designing my own extruder and that’s been combined with a slice liquid mosquito.
-
@nuramori Wow, not cheap. Are they good?
-
@deckingman kind of like an oetiker / stepless ear clamp?

@o_lampe that is very interesting. Not sure I would trust it... but interesting.
-
@nxt-1 they look very nice.
-
@lael nope, no leakage. But in my opinion, it would be better to have a real fitting. I'm gonna change it soonish.

@t3p3tony @o_lampe - thanks - I've got a test rigged up with FEP hard tubing going into a mosquito liquid, and silicone tube over it just like this. I did add two oetiker clamps on them - I was surprised the FEP handled the pressure, but it seems fine, and no leaks with a 7 day continuous test time so far. If I firmly hold both sides I can still slowly slide the silicone over the inner tube, but I don't think it will come loose on its own.
