I'm pretty new to 3d printing and I was changing out my nozzle and broke the heat element and now I'm looking for a new hot end. I was looking at the e3d 24v due to the form about dual extrudes saying that 12v doesn't work with the motherboard. I chose the e3d due to the fact that it seams the most versatile and has a huge community behind it. but if the 24v wont work for the printer I don't mind springing for a OEM hotend. Many thanks to everyone willing to help.
