Introduction: PUMPKINATOR CNC

If I win the printer one of my other project would be to build this monstrosity "THE PUMPKINATOR"

Here is my idea for a CNC pumpkin carving machine.. simple concept pivot A axis for the pumpkin radius this will be adjustable in the z axis for different sized pumpkins. the B axis is servo driven, so is the rotary B.

I want to build the main components with a 3d printer. to make this cheap enough to mass produce.

Step 1: CNC Controlled Pumpkin Carver

Here I have some spare motor controllers from my robot arm project I can use to build the Pumpkinator. I also have encoders ready to install for feedback. This will be a quick and easy build. 

What an awesome instructable this will be. cant wait to get started. All I need now is the 3d printer.

Step 2: Power to Create

I also have some spare motors and gear reduction transmission to build the drive system for each axis.

Step 3: The Z Axis I Will Use a Dremel or High Speed Rotary Cutter for the Spindle.

Now for cotrol this is easy we use a standard printer interface. this is the easiest. all we need are 2d images the 3 axis are mainly 2 axis with the z only an adjustment prior to startup. the rest will draw just like a standard plotter. More on this later.

you should consider making the z axis a work axis as well-you can do some brilliant things with pumpkin carving b controlling the depth of the cut

well i have and on my finished version i will add z axis motion to the device. this will be a very stable milling machine for 2.5 d cad. i belive this will have a nich for the machining world. this could be a good patent. however i may have screwed the pooch and made this public domain. and lost my ablity to have a patent as well as anyone else. so we will see.

that is why i posted as a concept and not so much as a finished product. let me know if you want to help with the design and building of this concept.

You can still own intellectual property on it without a patent; as long as you picked an appropriate license when you published the instructable, you still own it, since nobody can use it without your consent.
