I would like to learn about the DIY side of cnc routing. I currently oversee an area at work that has two cnc routers depaneling PCB’s, which are built by ATI and cost about 80k a piece. As capacity increases so will the need for at least another machine or two. I'd like to have the option to maybe go a cheaper route and build a DIY one instead. These are strictly for cutting tabs on PCB’s to take them out of a paneled form. We don't need anything near as heavy duty as we currently use. Any suggestions on where I should look to start learning about what I will need and how to assemble all the pieces? Obviously reading here is a good start but any other info/suggestions would be greatly appreciated.
