Re: Printed Circuit Boards.

That would be great about putting the converter on your web site. I dreaded
having to convert excellon drill files to G code and add the Z up and down.
Even cut and pastig is inefficient.. Especially when your have 400 holes to
drill.
BTW where is your source for that dry film resist. I have been thinking
abouut picking up a laminator for several reasons.
