Introduction: PUMPKINATOR CNC

By Phantasm Robotics inc.
About: Former recon marine, did time in the Navy as well. build robots for a living, engineer as a trade. Inventor, Black belt TKD. battle bots. robot wars etc. Medal of valor recipient.

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.

    thanks to all of you for voting, as you know i didnt even win as a finalist so no 3d printer.

    thanks anyway. screwit I will build a better one myself.

    potato Coffee say this 2 me so i voted for u

    Please vote for sparten11's Instructable so that he can win the contest and build liads of great things. The Instructable is a blueprint of sorts but looking at his other stuff, you can tell he needs it. Heres a link to the Instructable: https://www.instructables.com/id/CNC-pumpkin-carver/
    This is what he said about it: "Ha thanks tell all your followers to go and vote for me too... lol I need all the help i can get. heck tell everyone you know, I am. I need that printer badly. I have just too many inventions to build. warren"
    Please vote for him and help him win! PotatoCoffee

    if i get the printer ya I already have everything else i need to build it. I just need the printer to make the frame etc.

    keep watching

    And please go vote for me to win.
