BobCad/Cam

Hi all new member here needing a little help with Bobcad.

I purchased version 20 and am having trouble setting it up for use for
use with Mach3. For example I do a profile, then I call for a tool
change and do another part of my machining. I can see the g code for
the tool change but when I run it in mach 3 it just zips right on by
not stopping for a tool change.

Any help would be great, I am a newbie so be gentle please.

Walt
