e3d mod

 * Attach a Cpu radiator to the http://e3d-online.com/Multi-Extrusion/Cyclops instead of the rc boat jacket mod to the finned all metal hotend http://e3d-online.com/E3D-v6. This is the implementation with Heated chamber.

One of biggest issues I faced with higher chamber temperatures was filament flow problems. When the temp in the chamber started climbing over 50 degrees a number of extruders I tried all had issues with filament flow, like intermittent flow or the extrusion stopping in the middle of a print for no apparent reason. Other issues were jamming and filament stripping. So I decided to design and make my own extruder to overcome these problems. My idea was that as the higher temps were softening the filament and thus causing distortion which then led to stripping, slipping and jamming. The reason for this I figured was the pressure of the idler wheel on the drive gear due to the higher pressure needed to stop slipping. By having two driven drive gears on each side of the filament I hoped to reduce the pressure needed on the filament and like a 4 wheel drive vehicle as opposed to a 2 wheel drive there would be more traction.

The glass plate sits on top of a 5 mm piece of aluminium. On the underside of aluminium I have attached a custom 590 x 380 mm silicone rubber heating pad. The pad is glued with high temp silicone. The pad is 240V 800W. This is wired into the ramps heat bed circuit using a solid state relay. The pad I ordered online from China for the ridiculously cheap price of 38USD. So I bought two! I was very skeptical about the quality of the pad I would receive but as it turns out it looks OK and been working without any problems. Re: E3D Water Cooled Mod

I can't find the original link for the pads but it was through searching Alibaba.com, but the email address is sales1kingheater@163.com and the persons name is Jim Zhang. The name of the company I sent the money to by bank transfer is called Honeywon International (HK) Limited. which if you do a Google search does show it as a heater manufacturer. You need to send him a drawing with dimensions and location and size of any holes you might want in the pad. Also give him the required voltage and wattage and indicate on the drawing the location and length of the power cord. They will make it in about 5 days.
