Hello there 
I am starting to build my own 3D printer (yeaaaah) and I already ordered a Duet 2 Wifi board. I was thinking of buying the brand new E3D Hemera extruder but when it comes to chose the 12v or the 24v version I can't say what is the good choice...
I am planning to use a 24v power supply, so should I go for the 24v version of the Hemera? (that simple??)
Thanks for your help
