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.
