EMC2 CNC Mill 3D Printer conversion, did I get everything right?(:P) (no replies)

Hi There

I have a large CNC Mill hooked up to EMC2 and everything is working very well. However, sometimes I'd be happy to be able to print some parts, so I decided I that I need to convert my mill into a 3D printer.

I read here and there, but so far I am not sure that I got evrything correct, so please tell me if my plan works or not:

1.) I Get an extruder Head (I'm not quite sure which one), Heated bed, Electronics to drive the extruder and to controll the hot end

2.) I connect everything to my CNC-mill host computer running EMC2. The extruder has to be configured as A axis.

3.) I control the temperature manually on the extruder, not through the computer

Is that everything? Is it that simple? What else do I have to take into account?

Oh and by the way: I am located in Switzerland. Were should I get the needed parts from? What is the nest source? If possible I'd like to get all parts from a single supplier.

Best regards
Joachim
