Hello everyone, I'm new to Eagle Cad and was wondering if anyone could give me a tip on widening the etched route lines when I go to make a PCB layout. I'm not referring to the actual traces but the lines that my CNC machine would etch out the copper during milling. Problem is that the smallest endmill I have is a 1mm and when I go to process the G-Code, it fails because the etch lines are smaller than my endmill. Any help would be very much appreciated! Thanks!
Hi guys,
Thanks for the replies. I went through and tried what you advised but all it does is thicken the trace and not the etched lines (the lines that show up black) -- which would be the lines that are milled by the CNC endmill (see image).
That is weird. I made a few screenshots.
I made this simple board with some normal .016 inch traces. The dotted line is the plygon for the copper-pour (ground pour).
I then hit the ratsnest icon to get the plygon filled using standard .016 inch isolation :
I then selected the polygon (either right-click -> properties or using the 'i' icon) and changed the isolate to 0.032 :
As you can see this should do what you need (unless the blue plane in your board is not done using a polygon with copper-pour, but it looks like it is).
Of course, the distance between normal traces (not between a trace and a copper-pour/plane) is controlled by you if you route manually, or by the clearance parameter in the DRC settings when using the autorouter as Mogens indicated.
Hope this helps,
Guido
