Aluminium heated bed for i3 mini

SummaryHaving access to a hobby CNC I decided to try to cut some aluminium with it. Not sure I will succeed but it is worth trying. I will use a couple of 6 ohm / 25 W resistors expoxied to the bottom as heat source. A pocket in the bottom has been created to reduce the thickness to 2mm so lower thermal and mechanical intertia will be present.
