We’ve all heard about it, but how useful is it?
I currently own a Printrbot Plus Metal, Dual extruders and a heated bed.
also own
a Printrbot simple makers edition fitted with a single extruder and heat bed.
I recently built a mini Kossel delta kit. It has a single extruder and a heated bed.
By the way, its very useful. If your a maker of any type, ya need one..
