P-CNC Plotter Disguised As a Quadruped Robot
Introduction: P-CNC Plotter Disguised As a Quadruped Robot
This is my P-CNC plotter which is laid out and disguised as a quadruped robot. Today, I'd like to share how I made it. It was quite simple, no 3D printer required, just need my meticulousness, care and a little patience.
Please check the brief description and how P-Plotter works in the video below before getting started.
Step 1: Supplies
Main components are as follows:
* 1pcs x Arduino Uno R3: Amazon - Banggood.
If you are new to Arduino, you can buy a kit named "Grove Beginner Kit for Arduino" with 10 additional Grove Arduino sensors all in one piece of the board. All modules are pre-wired, no breadboard and jumper cables required. 949
And it will bring you the simplest way to get started with Arduino.
* 1pcs x Arduino CNC Shield V3 GRBL: Amazon - Banggood.
* 3pcs x Stepper Motor Driver A4988: Amazon - Banggood.
* 2pcs x Stepper motor NEMA 17: Amazon - Banggood.
* 1pcs x Old CD/DVD Burner Writer Rom Player Drive - Compact Type: Amazon - Banggood.
* 2pcs x Round Bar Shaft Rod Diameter 8mm, Length 400mm: Amazon - Banggood.
* 2pcs x T8 Lead Screw 2mm Pitch, 8mm Lead , Length 400mm with Copper Nut: Amazon - Banggood.
* 12pcs x Ball Flanged Shielded Bearings 8 x 22 x 7mm: Amazon - Banggood.
* 1pcs x Aluminum Flexible Shaft Coupling, Inner Hole Size: 10mm x 10mm: Amazon - Banggood. It is used to clamp the pen/ pencil.
* 2pcs x Aluminum Flexible Shaft Coupling, Inner Hole Size: 5mm x 8mm: Amazon - Banggood.
* 2pcs x XH2.54mm – 4P 20cm Wire Cable Double Connector: Amazon - Banggood.
* 1pcs x 5mm DC Female Power Plug: Amazon - Banggood.
* 1pcs x Power Supply 12VDC: Amazon - Banggood.
* 1pcs x Clear/White Acrylic, size A3, thickness 5~10mm: Amazon - Banggood.
* 1 meter x 8P/16P Rainbow Ribbon Cable: Amazon - Banggood.
* Some small cable ties, cable spiral wrap, bolts and nuts.
PVC pipes and its fittings:
* 1 meter x PVC Pipe Ø42mm.
* 1 meter x PVC Pipe Ø60mm.
* 1pcs x Cross PVC Pipe Ø42mm.
* 6pcs x End Cap PVC Pipe Ø42mm.
* 6pcs x End Cap PVC Pipe Ø60mm.
Tools:
* Drilling machine with drill bit 8mm and drill bit hole 22mm.
* Hand saw.
* Soldering machine.
* Big scissor.
Softwares:
* GRBL firmware.
* Inkscape with Gcodetools extension.
* Universal Gcode Sender.
Step 2: Schematic
The schematic & connection diagram is very simple.
* Plugging the CNC shield on the Arduino Uno R3.
* Plugging three stepper motor drivers A4988 on the CNC shield at X, Y and Z label position.
* Connecting the cables from stepper motor drivers to three stepper motors.

Step 3: Drilling and Cutting Works
Due to the COVID-19 pandemic, my city was locked down, I couldn't go out to buy materials and electronic equipments. So I had to use what remained in my hand, especially PVC pipes and its fittings.
Firstly, I imagined a robot-shaped CNC plotter and sketched it out on paper to estimate the pipe fittings. 1000
