The higher the printing temperatures, the more the poor cooling of the hot ends and the extruder motors becomes apparent.

I'm also seriously considering this mod. I've made a half dozen requests for quotes on the water block. (I'm in the US) I used the Heat Exchanger v21 step file. I'm too new in the group for my PM function to be enabled. So I'd like to thank Markus64 for the tutorial work and the files he has provided, along with the others that have shared their variant on the modification.

I fall firmly in the 'this hotend assembly should have been built differently' camp and I'm fine with that because the rest of the printer is pretty good. It's not my first printer so I'm familiar with fabrication for modification. I still have and use both my Replicator I and II of which both are heavily modded.

I'll be going to order a pair of water blocks and see how the quality is and how just the hardware up to the pump is acquisitioned price-wise. I was surprised at the twenty-unit price for the water blocks. What I'm getting here, with the okay from Markus64, is to possibly kit the parts up to the pump for our US crowd. Seems the pump and radiator are common, plentiful, and adaptable enough to allow for a personal preference, appearance, or flair for one's own build style.

Give me a shout if there is any interest.

it’s there, the installation works. I added 2 temperature sensors and modified the flow indicator systems.
I also changed the cable chain and its support. Now all I have to do is run the pipes through the cover and make parts to wrap the pipes around the nozzles.
The heat exchangers are very inspired by the Markus model, thanks to him.

The heat exchanges cost 70 Euros + tax and transport, if at least 4 pieces are ordered. The payment has to be in advance. Is there anybody from Europe willing to order them together with me?

Hi Dirk, I recommend you keep the second sentence as a reserve. So did I too. With this type of custom-made product, this makes a lot of sense. ;)

Excellent thread, looking forward to the machine becoming reliable again.

What takes a long time is finally good ☺️
My "printer corner" is finally there
Raise3D Pro2 with water cooling for heat breaks and extruder motors, magnetic component fans and the Z-support for the energy chain.
Print results have never been so homogeneous and 50h prints over 240 ° are finally standard!
The money and the effort were worth it, even if I have to say that at the price it is an outrage that you have to lend a hand yourself in order to be able to work properly.
Thanks to Markus64 and everyone else from the official Raise3D forum!

Well done, looks tidy up! After introduction of all countermeasures my Raise is a bit boring - it just prints...

Does anybody in Europe (or even better in Germany) still have a set of the extruder coolers?

Hi guys,
you all did a great job with your conversions. The reward for all the effort is a better Pro2 than the one delivered from the factory. I generally recommend keeping two heat exchangers as a reserve. If the structure does show microcracks, you have a quick replacement and do not risk downtime. The 70, - € per piece here is a first-class price and consider that every heat exchanger is a custom-made product that you cannot get on every street corner.

I look forward to many more positive reports about your conversions! :D

Johnz, is the offer still available for a parts kit or at least the possibility of a bulk order with you?
I am brand new to the Raise 3d Community and own two Pro2 printers. I am/was very discouraged when my printers started having serious heat creep issues within a couple of months of purchase. So needless to say I am very happy to see this thread.
Can someone please provide me with the a link to the files since the links earlier in the thread end in a 404 error.

Thanks to Markkus64 for starting this and all of the hard work from everyone!
