Hi Taylor,

I have forwarded your email to my colleague who manufactures my heatsink design, however I am including his email here for you... penglish@englishmfginc.com

He is a Pro 2 user as well and we both have many hundreds of hours combined on our Pro 2s without throat freezes since we changed over to water cooling. It is a far more efficient way to transfer heat.

Thanks for inquiring.

Edit: fixed misspelled email address.

OMG that's insane! Kind of seems like a lot of weight to add to the extruder assy, did you notice any negative affects from the additional weight? The linear rods sag as it is with it in stock form.

The net gain on weight after removing the OEM fan and heat sinks was very modest. The huge improvement in printing reliability was absolutely worth any negatives, and honestly we have not seen any detrimental effects at all. The stock air cooled heatsinks are only slightly better than worthless, IMO.

Are you drawing 12V for the pump and fan from one of the boards, or are you using some sort of DC power adapter?

I have heard that some users who are intimate with the Pro 2 electronics have tapped power from the printer, but we simply use a standard 12 VDC power brick. We plug it into a switched box that also powers the printer. When the switched box is on, everything is on. Works fine.

Hi all, I have a set of Paul Yarnall's heat sinks for sale if anyone is interested. I am located in Toronto, Ontario Canada but they can be shipped to anywhere since they are small and light. PM me if interested and we can discuss price and shipping details if needed.

Sort of copied Paul’s design, but 3D printed (DMLS) in aluminum instead of machined.

Hello, tried to PM you but apparently I haven't posted enough to send PM's yet. Also interested in getting a copy of the SW files...

thanks
Paul

Nice! I got a quote to make a set out of copper here in Toronto but they wanted $1000. So I had a set made of my own design instead. I had the main part machined but bent and soldered the tube together myself. Total weight with set screw 12 grams.

That’s so simple and ingenious.

Thank you. Simple yes, ingenious I’m not so sure.

I'm interested in designing a block but I'm too afraid at the moment to break down my new machine. do you have the dimensions you used to build your model? or if you can share your model that would be awesome.

Thank you

Andre

Hi Andre,
if everything is built and installed correctly, nothing better can happen to your new machine. The original cooling of the hot end is just horrible! There are printers that cost only a quarter of the raise and are more sophisticated. This is my experience of the past 3 months. Be happy if you haven't had a clogged nozzle or a clog up towards the extruder motor. For a new hotend in Germany I pay almost € 100, rather more.

Not to mention the downtime, the repair time and the annoyance ...

sounds like you need to have a couple of everything as a backup.

I actually always have nozzles and throat tubes in reserve. Nozzles are almost always available, but the Throat Tubes can be tight in terms of delivery and the price is not cheap. At least that's the case in Germany.

The water path is "U" shaped when viewed from above and goes around the throat tube. In, back, over, back to the front, and out. The throat tube is in complete contact with the copper heatsink minus the width of the clamping slit in the front of the block. That is inconsequential.
