    You mean, using a 3D printing pen like a 3 Doodler? Is there a specific reason you would want to go that way rather than make a more traditional setup with a higher power extruder and hotend? You may run into some issues with the host software (Repetier, Simplify3D, Pronterface, etc...) not having any control or feedback from the hotend for temperature control.

    If you do want to continue with the pen idea, then you are going to have to be more specific about which pen you are using, and the CNC shield that you have.

    Well, the link was just for filament. Anyway the same question as earlier still stands. Why buy the pen, when you can get a more accurate, repeatable, and reliable setup with a dedicated extruder and hot end that was designed for use with a 3D printer? If cost is a concern, you can get Chinese knock off parts for dirt cheap. You should be able to get a MK8 extruder and hot end for under $40.

    You will most likely want to use the spindle enable pin, which you can find on the right side of the board labeled SpnEn

    Now, I have no idea what the control voltages are on the 3D pen, so you are on your own on that one. Same with modifying the g-code to make it all work.

    I'm sure you have your reasons for doing it this way, but using more traditional parts to make a 3D printer will make your life a lot easier. A Ramps 1.4 shield loaded with Marlin firmware would make this far easier.

    The CNC shield won't be able to handle it, as it doesn't have connections for the thermistor input and the heater output. For this, it really is going to be easier to use a Ramps board with an Arduino Mega2560. It has all the connections you need for a 3D printer, and because it's used so much, there is a ton of information out there on how to connect the hardware, and configure the software. It also helps that it's dirt cheap.

    If you are going to buy a Ramps board, drivers, Arduino Mega2560, hot end, extruder, and now looking for a 3D printer frame, why not just buy a complete printer? You can get prusa i3 clones pretty cheap with everything you need to get going (just avoid the acrylic framed ones).
