This is the story of my progression from the JGRO cnc router design to using the OpenBuild system. In the process I think I have learned some. Steps for: Build a home made CNC machine (JGRO router). Step 1. Step 2. Step 3. Step 4. JGro CNC router from Stock setup. There is an error in the Z axis assembly – the fixed section holding the tubes on which the slide moves is too.

I’m also interested in your progress since I will be constructing my first CNC machine in a couple of routee. Its entirely Johns fault that I’m building this table. By the way, John is a far better craftsman then I, so we can expect a higher grade of work from him.
The Hobbycnc kit came with 14 feet of 6 wire, 22 gauge, more is needed for this machine. Results 1 to 12 of Sheetcam demo looks good for generating gcode, and working with flat material.
This project is in progress and I will post the steps as I go along.
