Project CNC - November 2007 - Ongoing
Well, you have to start somewhere. The
hardware, wood, metal, and electronics are
all acquired. Part fabrication is almost
complete. The finished machine will be able
to handle up to 25" x 37" items. Plans
provided by David Steele.

After cutting all wood components from
oak, they are treated with a medium stain.

Some finished wood parts.
Plastic blocks that will hold bearings for
leadscrews. These were made from a
single plastic kitchen cutting board.

Aluminum parts.
I thought it might be fun to make some
parts out of Plexiglas rather than 1/4 inch
hardboard.

View from the back. The Y axis
stepper motor is mounted on the
left. Y axis lead screw extends out
from the motor along the bottom of
the y axis gantry.
The only remaining tasks are to
connect the X and Y gantries to
their lead screws, install limit kill
switches, complete wiring to
stepper motors, install 110v router
power with speed controller, and
make final adjustments.
A new digital level was acquired
today to verify and square up
alignments to a 1/10 of a degree.

I obtained a spring loaded, ball
point tipped, plastic pen ink tube
and mounted it with the spring
between two small blocks of wood.
I used super glue to attach the
blocks to a small base. The base is
attached to the Z gantry with a
single wood screw through the
existing hole for the router attach
screw.
I drew a uniform grid with hand
written G code and used the
Mach3 lettering wizard to
demonstrate that capability. All the
curves drawn are amazingly
smooth even down to 1/4"
diameter circles.
