Hello, just thought I'd introduce myself - I'm a woodworker - I have been working with CNC router machines for a few years now, I started off building from scratch (ballscrews, chinese spindle etc etc) and now I have an ancient Gerber System 48 that I bought on eBay. It was originally made for sign writing but I have modified it so I can get 100mm under the gantry, and I've changed all the stepper motors and electronics. It's a well built machine and I've just got it running properly today.
There's another guy who has done up a Gerber System 48 and he's put a video of it on YouTube - I'll do the same when I get some time
Cheers
