I'm guessing that this may have been covered somewhere before but I cannot seem to find a definitive answer. I use an Ultimaker 2 and am looking to upgrade to the E3Dv6...the questions that I have are: can I, if so which voltage do I want? 12v or 24v, is this just looking for problems, etc? Anything that you all think I should know before I embark on this? and so on...Thanks in advance.
