Is This True or Bad Information

This is a letter forwarded to me by a friend, he knows I am in the
process of converting a homier mini mill to cnc, using stepper
motors and The Motion Group 4 amp three axes controller and a
laptop... I am making my drawings with autocad and coverting them on
bobcad and turning them into g-code, the contoller runs maxnc and
seems to operated fine with motors hooked up and running with the
code on the kitchen counter, still have to get the pullys and belts,
make the brackets and mount the motors, limit swithes, optical
homing switches. What are your comments about this letter forwarded
to me. Should I give up on my project or proceed full steam ahead.

Dear William,

The deceiving part about the CAD CAM world is that in order to
make
most parts yourself (without sending them out) you need to know
two
programs. The first program like Artcam, Rhine Matrix,
Cimigraphy and
Type3 does the design work producing all the dimension and
surface
relief of the item. The second program runs the CNC mill or solid
modeling machine and turns the design program file into an actual
item. This is not the case with every system, but is most of the
time. With any CNC mill the most important part no mater what
anyone
says is the speed of the spindle. If the speed is not up around
15,000 rpm don't but it.

Best Regards,
Todd Hawkinson
