Well I built my JGRO to cut the parts for a Joe2006-R2 which I have completed. Don't need the JGRO and was wondering if any one is interested in the metal parts for it. I built a stock JGRO. I have the pipe which has been sanded down on my dad's lathe. The bearings the ride on the pipe and 1/2-10 acme rod for all 3 axis with nuts.
It was a blast to build, well worth the time and the knowledge that I gained. It was a great starter DIY CNC machine.
Here is a picture of my JGRO before I dismantled it.
