Recently I purchased a CNC jr. I'm very happy with it for the most
part but there doesn't seem to be very much native G code for it.
There's no G code for tool diameter (radius) offset for example. It
looks like I'll have to get a cam program sooner rather than later. I
will be using AutoCad Lt for the design portion. I'm interested in
suggestions for a cam program that will work well with such a
restricted native G code. I don't need any design features in the cam
program since I've already got CAD. Any info would be greatly
appreciated. I really would rather not pay more than 600 or 700
dollars.

Another question I have is about using cutting fluids with CNC. The
system I have that came as an option with the CNC jr seems like it
puts out too much - It makes a mess of everything. Are there any good
ways out there to manually control the flow. Also I would like to use
a vacuum system for the metal chips that I already have set up for
woodworking. What's a good method to get the chips without sucking up
the cutting fluid? I've got a recirculating system for the cutting
fluid and its too expensive to just get sucked away. Thanks in advance
