Upgrade: this project has been closed and will not supported: The Reason: look here: https://www.thingiverse.com/thing:3590034 Upgrade 03.05.18 This Project has been stopped temporarely, because I'll buy my own 3D CNC milling machine: https://www.cnc-step.de/cnc-fraese-high-z-s-1000t-kugelgewindetrieb-1000x600mm/ (the link shows only the basic model) Then I'll be able to create all the water-cooling Elements I need! V3: V3 will be water-cooled. I want to modify some wooden parrts, but Piquard can't do it for me. So I need a new specialist with a good working CNC milling machine. The 1.8A Nanotec stepper motors will heat up the RAPS128 too much. a 120mm cooler cools permanently the RADDS. The motors which turns the spindles with the zero-tolerance screws need power. They heat up, too. When printing Inofill ERP-PET with 140mm and 3D honeycomb infill, the motors (with coolers and fan) go down or loose steps after a time First I bought a water-cooling kit from youprintin3D. https://youprintin3d.de/hotendszubehoer/e3d/wasserkuehlung/834/water-cooling-kit.html?number=Water-Cooling-Kit Warning!!! Never more! It's a very cheap chinese kit. As it has been filled with coolant, bubbles came up, burst at the surface and some grey fume came out of them. The clear coolant changed into a milky sludge. As it has been connected to the 12V power supply, none of the electrical components were working. youprintin3D was not willing to take it back. They told me, that I was not able to connect it correctly. The + and - should have been changed and the electrical components damaged by me. A friend of mine disassembles it and will identify the truth. And it looks good for me and the company which paid for that trash! Update: youprintin3d contacted me. I should delete the entry above. I'll never delete my impression about that product, but I'll delete my words about youprintin3d when they are willing to give me back the money. First Step: -Building alls parts, which are needed for the diamond nozzle. -Building the base for a circuit which cools all my 9 stepper-motors, the 9 RAPS128 and the diamond Nozzle Bought things: - Aqua Computer Aquastream Ultimate pump with Aquainlet Pro reservoir. (Hot parts. You're able to connect them to your PC via USB. With the software you're able to control your system. Fans, temperature and flow control sensors can be directly connected to the pump or the reservoir. There are a lot of more options. You're old enough to read it yourself at manufactors side). Update: The Aquastream pump is great, but it has been developed for PC cooling. Problems: 1) The controlling Software is only available for Windows 2) the USB wires are confected for Mainboards. I modified them to plug them into a USB A port. 3) All the other wires are too short. The power connector is a SATA connector - Aqua Computer Radiator 240mm - Plug&Cool tube system 6/8mm with different connectors - A Diamond Full-Color Nozzle water-cooled. (It's fully assembled. That's a little bit tricky. Problem to solve. The water connectors are too small for a full cirquit. The PUR tubes have 6mm ID. Other components 6-8mm ID. The connectors of the diamond nozzle has only 2 mm. The pressure rises. I'll solve the problem) -BL-Touch smart height sensor for autobedleveling! All parts for the diamond nozzle have been printed. - Spool holder - filament cleaner - holder for the stepper motors - the nozzle holder All parts for the water pump have been printed. - Platform for the pump Update: 25.03.2018: The connectors for the 6/8mm tubes are implemented. Look at the photos. The pressure for the pump has been decreased. Now, I have to recreate the Holder! Update: 17.04.18 After some testing, I decided to recreate the heatbreak system. The original heatbreaks are not really good. When the printer retracts 2mm of one filament it cools down and clogs the heatbreak. I'll test coated heatbreaks (from mapa-refining) encapsulated with copper. The copper parts will be built into the cooling element. Second Step: develope and connect waterblocks for the RAPS128 and NEMA 17 stepper motors (will follow)
