Heads up: I'm not good with electronics and only have a vague idea of it's inner workings.
I have a E3D V6 Extruder rated for 24 V, that i plan to use in my 3D printer. Will there be any problems with it if powered by 12 V? Will it take longer to heat up? Will it be able to heat up enough to melt PLA? Will it work at all for that matter? If there are any other quirks or potential problems that I overlooked, please let me know.
