Try this one: http://cynbe.us/~cynbe/gcoder/ I had to modify some functions to make it work, and it doesn't support poly fills, but I think it's not an issue if you mill a pcb. 2009/6/20 Bill Gatliff : > Dave N6NZ wrote: >> Some of us local roboteers have been considering this unit but no one >

Some of us local roboteers have been considering this unit but no one has plunked down the money yet: http://www.probotix.com/FireBall_v90_cnc_router_kit/ You could probably put together a CNC router capable of doing PCB's for under US$1,000 Still personally I'd rather send PCB's out and s

I have heard of people using a regular CNC mill or mini mill like a sherline. The real trick is to have a very fast spindle speed ~50,000 RPMS. I have a PCB mill that I built, but I still have to finish my stepper motor drivers. The hardest part is the file conversion for driving

The Fab Lab in Boston uses a Roland Modela MDX-20. There is a python script that translates the gerber files that Eagle creates into routing commands (http://web.media.mit.edu/~neilg/fab/dist/cam.py). I brought a couple of Gerber files (created with gEDA/PCB) to try routing a board using the milli

I've been thinking for a while about CNC milling as a means of board fabrication over chemical etching. The limiting factor for the idea is cost. Every premade PCB mill I have found has been well over $3000UAU. One LPKF mill I found, which was advertised as their 'budget' model started at $20,0
