low cost table top machine. ( was Re: Move x,y,z according to GM-Code?

Hi,

If I am correct inreading what you have already posted, you already
posted, you already...

have the drawing program to draw your parts.
have the ability to get DXF or HTML files
and can convert to G-code.

get Turbo-CNC to round out the software.

for hardware for an engraver, you need to make a machine. for that
you can be as simple as a 3 axis unit that runs on very simple rails
and stuff.

I bought some 3/4 wood panels that are for closets. and it has a
white plastic coating.

cut that into pieces for your machine. I got about a 12" x 8"
working area.

them you can mount simple bushings to use as slides and some drill
rod for the rails. 3/4 inch dia should not be too expensive.

this would offer a very simple unit that you can put on your desk to
play with.

the total cost should be under $100.00, but do not expect it to cut
heavy parts or to last a long long time. this would be for
experimenting, or really just playing with.

it would be good enought to use for drawing and making simple circuit
boards.

Since this design is really for experimenting, I used 3/8 all thread,
direct mounted to the stepper on one end and taped a Nylon block that
I bolted to the carrage. the only bearings were the ones in the
steppers and those will move as they are not designed for axial use.

once you surf the web and see how each axis needs to move, you can
make a simple design.

But, if you want a full set of plans, there are some guys on here who
have documented the whole thing and have a proven design. it may
cost a little $$$ but would be worth it.

HobbyCNC has plans for a unit that uses a dremel. that would be a
great place to start for a simple and low cost machine.
