Hi, Daniel.
 
	I would be very much interested.. Sounds a very nice option when you
have hundreds of hole to drill by hand :-(
 
Best regards,

Assunto: [Homebrew_PCBs] CNC Drilling for Toner Transfer PCB

Hi,
Toner Transfer is an acceptable method for fast pcb prototyping.
It has 2 disadvantages : the drilling should be made manually and the image
doesn't have exactly the same dimensions as designed - this way the
automated drilling it's not possible directly.

For Mach3 driven, cnc owners I have made a solution based on a webcam
mounted aside from drilling motor, a modified video plugin and a small
program for conversion/rotation/scale of excellon drilling files.

If it's someone interested in this solution - I will post all the needed
info. 

Regards,
Daniel
