I use WinQCad (www.WinQCad.com) to generate my PCB layouts. I've been using photolithography methods so far and its worked great. It also generates 274X gerbers and Excellon drill files so I downloaded a few Cam demos and tried loading them to see what I get.
Two problems I've run into:
First, the drill sizes are always 10 times larger than they're supposed to be (350 mil instead of 35 etc). I've tried playing with the leading zero settings which seems to only result in all holes disappearing. Here's the tool section of the excellon file
M48
INCH,LZ
T01C000300
T02C000350
T03C000570
%
What should I change it to in order for (most) Cam software to read this as 30 mil, 35 mil, and 570 mil?
Second is unwanted text in the gerber. QCad includes registration marks and text that are useful for photo processing but useless and time consuming to route. Anyone know any software that I can use indicate and remove these entities?
Thanks for any assistance you can render!
