BUILD a PVC CNC PLOTTER IN a SIMPLE WAY
Introduction: BUILD a PVC CNC PLOTTER IN a SIMPLE WAY
Today I'd like to share how to build a CNC plotter and in the easiest, simplest way which I've been done. It has a good looking structure, pretty good plotting quality, with a working range about 300 x 300mm. The CNC mainframe and supports are made mostly of plastic materials, such as: PVC pipes and acrylic sheets.
In this project, I used PVC pipes & fittings Ø21mm. All the bearings and copper nuts are fitted tightly with their holes, so everything becomes quite easy and my CNC does not take up much space.
Please check how it works on introduction video before getting started!

Step 1: CNC Main Frame
The CNC base and main frame were assembled from PVC tees and straight connectors Ø21mm with a inner size L x W about 500 x 500mm.
The PVC tees have been arranged horizontally and vertically, as follows:
* Four horizontal open holes: be connected to the CNC Y axis. 1000
