The block is cross drilled so it goes in one side, back, across and forward to the front then out. You can see the gap at the front? That slit goes back to the 6mm hole and allows clamping on to the throat tube, so the water route must be a "U" profile. Extremely effective. Possible that aluminum would work adequately, but I was going for broke and copper has far better heat conduction.

Did you ever get any interest in getting these blocks produced? I am experiencing similar struggles to what you have described and my current cooling setup is no where near as elegant as adding waterblocks. I would be interested in purchasing two. I would only need the blocks and what size barbs you are using.

My friend and colleague who owns a machine shop is starting a batch as I write this. I will DM you with contact information.

Its really amazing what we as customers has to make to achieve the results we expected when buy the pro 2. To be honest I bought the machine for bussiness pruposees however it didn had result as I thought. All the problems you have listed I been passing and by this point Im a kind of frustrating.

Great job pjyarnall I think maybe I will make something like this.

Add to the list: poor or basically absent layer cooling, no bed leveling, no non-linear extrusion, and no industry standard nozzles - all things present or easily added to printers that cost less than $1k.

Very frustrating.

I too am having similar problems with high temperature filaments. Are the heat sinks available?
Thanks,

Mike

Sign me up as interested too! I plan on running a bunch of nylon and it's in an unconditioned space which can get toasty in the summer.

Sorry this is so late but the water cooling part replaces the heat sink. If you look at the picture in the post you can see it’s a hollow copper block.

Thanks MDVolle. I print mostly PLA and Ive actually been running the machine with all the doors and covers open to try to counter the heat issues. I believe there is about 1/4" or so clearance between the motor and the frame when printing at the bed limit closest to user, so Ill try a short heatsink.

Recently, Ive been experiencing a lot of jams, especially with long builds and Raise3Ds Art White material. This seems to be somewhat of a reoccurring theme with the Pro2 lately on the forum. There is some speculation its due to heat creep or improper heat dissipation through the extruder. Since you are running typically higher temps have you been plagued with a lot of jams?

Hi all, this is my first post. I just wanted to share my water cooling build with the community. I did both the X and Y and extruder steppers as well as the heat sinks from Paul Yarnall. It added a net of 91 grams to the head after removing the front fan and associated hardware. Haven’t printed yet just did a hot test to see everything works.

Shabby.... A very nice installation! The extruder motor cooling will definitely be of value. Not sure the axis drive motors need cooling as they can be hot to touch and not cause any harm. The hot extruder motors preheat the filament and that IS an issue for some filaments. I look forward to hearing how your printer works with the mods. Without the water cooling I would have had to abandon the printer.

Do you have a drawing or model of the water block? I’m thinking about doing the same thing with our Pro2 Plus after having to tear apart the extruder for the second time this week to clear a jam between the Teflon guide tube and the lifting assembly.

You can ask Paul Yarnall, he posted right above me. I bought the heat sinks from him.

I wasn't sure if I needed to cool the X and Y steppers either but they do get hot. I have not printed with the lid down yet and figured it will only get hotter from here on.
