Bill,

Could anyone please tell me if LazyCam yet supports PCB isolation milling?

I don't see anything specific to it in the program ( v3.002). The program is undocumented and Beta. The program is basicaly a broad range file importer to Gcode generator, and not to my knowledge, dedicated to some specific task other than general milling and turning using available tools
in it's current state. So you need to keep the above in mind.

You may want to play with the SETUP>LOADING OPTIONS to see if some settings will help when importing a file.

As mentioned in this post, and by you, there are specific programs that may be better suited to the work you want to do.
