Hi folks. I am seriously thinking of purchasing an i3 plus mk 2 but I am concerned that the controller connector issue in earlier units is potentially unfixed. If there is still a risk of overheating and fire with these new models that would be a concern. Does anyone know if the fundamental issues have been fixed i.e the circuit board for the controller had insufficient copper thickness and trace widths, causing the connector for the heated bed to overheat and fail.
