I packed all motors and boards from old printer in the box and it is waiting for next diy project.
The Creality would need some kind of enclosure and vent it outside. I don't think sitting in the room with 3 working machines is good for my lungs. I have an idea for that, but waiting for my move to new place in few months. I will create special cabinet for all of them while watching gearbest for next price drop :)
