I went to the site anyway, just to look. It is dated June

Hi John.

Send a request to my email address with your postal address and one will
appear there as if by magic. The BDI 2.18 is still $10. The TNG is $30.
Shipping and handling is included to the Americas. You can pay by
PayPal, check, or Money Order. Bill (aka list mom) tells me that this
group is absolutely trustworthy so mention CAD_CAM and pay up front or by

I looked seriously into buying one these CNC bridgeports; speaking to
engineers who work on them, it transpires that the motor unit / head
splits down quite easily, and allows the machine to be rolled on steel
rods under a standard garage door height. Be careful about the weight
though, it's a scary thing to move on an inadequate crane.

In the end I bought a non-CNC series 1, and some stepper motors and
other gubbins to give me CNC control.

WTTool makes a 3 axis one for $250. I'm working on a design for a 2/4

There is also an article in Circuit Cellar November issue on using
Gecko drives in a CNC application.
The magazine can usually be found at Barnes and Noble or you can
download the article from their web site at www.circellar.com. It is
not posted yet but when it is will probably cost you $1.50.
The magazine is mainly for hard core Electronic Engineers. It is an
excellent magazine if you gravitate that way.

Hi Tim,
That looks like the one I converted to servo with gecko drives and
EMC. These are hard to find in Texas, had to get mine from Alabama.

Lloyd,
The closest thing would seem to be the Hobby show at the International
Center in T.O. Nov 8-9-10.

The Toronto Miniature Engineering club is _always_ there with their
projects and last year (?) there was a couple small home made CNC rigs.
BTW, the scale Ferrari built in Meccano was pretty cool also......;'>

Of you are intent on this approach you will find that cheap drill
presses not only have crappy bearings, but the spindle is not stiff.

The rack and pinion gear that drives the spindle is very very sloppy,
and there is no adjustment. that pretty much eleminates that from
being a part of the CNC. unless you can figure out how to compensate
for a backlash of something over an eight of an inch.

for drilling, you have a chance, and if you do very light loads, you
can make a cutter stabilizer to take the side loads. not complicated
or too hard if you have access to a lathe or mill.

and last but not least is the machine ridigity. with only a very
slight pressure drilling with a 1/16 drill into aluminum, you can
visually see the machine flex.

The XY tables for $110 are a great start, a trim router for another
$50-100 is getting much better and then buliding a fixed mount for
the router on a plunging Z axis is not too hard or expensive.

Of the 4 HF el-cheapo drill presses ($39 to 49) I have one that the
chuck falls out of regularly, but the bearing and spindle are decent.

I have one that the lower bearing is not seated. the bore is too big
and the bearing slips.

I have one that the spindle is noticbly sloppy in that you can feel
the play.

the last one is 10 years old and is not a valid unit for review.

Another issue is that most drill press spindles use a taper to

mount the

chuck. These tapers are not designed for side loads so you would

have to

come up with a different way to hold your cutters. You do not want

a

spinning chuck to come off while you are milling.

The problem is that you cannot use a drill press as a mill because

of

the slop in the spindle assembly. The enco mill drill tables for

$119 is

a better deal in the long run but figure out how you plan to do the
spindle first.

Now my question : I bought a cross-slide vice yesterday and my

on my drill press then I might have a cheap mill' - I suppose a lot

Does anyone have experience with Rhino3D and VirtualMill 4.0? How well
do they work together? The demo version of VM does not allow you to
save your work and the imported images from Rhino vary a bit. Since I
am unable to cut anything using the VM demo, I would like to hear from
those who have experience with these 2 software packages before I
invest $995.00. Also I am interested in a good book that teaches
G-code for a newbe with a limited IQ...please nothing heavy duty that
requires prior knowledge.

Thanks Dennis

I am requesting information for a friend that has recently purchased a
Matsuri 5V from an auction. He has paid for the software package,
however the machine did not come with a 3d key...as a result he is
unable to operate in the 3d mode. His interest is to add a 4 axis and
would be interested in hearing from others who have this machine - an
electrical schematic would also be of great interest. Please e-mail
him at Twollesen@....

Thanks Dennis

I expect to need a 2-axis resolver to quadrature board, so

I did a bit

more checking.

The evaluation board price above is quantity 1.

Unfortunately the above price for the chip is quantity 100

and is not

available for online purchase from Analog Devices WEB site.

Pioneer has ad2s90ap in stock with the quantity 1 price as

$44.86. You

probably want an ad2s99 reference oscillator @$10.73 too,

but out of

stock.

At a guess a 2-axis board with just quadrature output

could probably be

hand wired for around $125 with all new parts.

More thinking is in order; such as serial out to a computer.

I have looked at these, and someone finally got smart! The

cost for a

12 bit board back in 99 was very high. It took 2 8 bit

converter chips,

a special chip to add their outputs together, and a high

priced osc. The

8 bit chips were on the order of $300.00 each as I remember, and the
adder was about the same.
Bill Higdon

Another thing I have been contemplating is the Maxim
MAX157/159 10/20 bit A/Ds
along with something like a DS89C420 (33 MHz clock) or maybe
the Basic-X
stuff to do the arithmetic, but I haven't come up with a
simple way to read
two signals at the same time since the samples must be
perfectly synchronized
to the peak of the reference signal. By the time you add a
sample and hold
chip in front and then read each sample things start to get
complicated.

A really interesting solution would be the one TI has in a
TMS324F240 DSP
application note. The approach could be really interesting if it was
completed. They don't appear to publish complete code for
what they do and do
not include quadrature output in the design. The code for one
axis, including
reference signal generation, used less than 25% of the
processor, so it would
appear that a 2-axis board might be hand wired for about $50.
As usual TI
wants a bundle for the associated compiler, but there is a
GNU version at the
usual price 8o). One would also have to come up with a way
to burn the
program into a chip. I have never gotten into DSP and would
really prefer to
make chips with machine tools.

The more I write, the better the AD2S90s look <g>.

Thanks for the suggestion; It looks interesting. In this case we need to
measure two signals at exactly the same time which will require either two
separate A/Ds per axis or external sample and holds. I was looking at the
Dallas chip both because it appears to be fast and also because back when the
8046/8051 family hit the market I did some design with it. I didn't have
access to an assembler or development system, so had to make my own and hand
assemble the code. I may actually remember something about the code. It's
only been 25 years or so <g>

Hey, No problem. I was trying to offer assistance. BUT, I can understand
fully what you are saying.

At this point in time, other than stupidly on my part; I have had no
problem with slippage etc.

However you go, I wish you luck.

The reason for the cost increase is the linear strips instead of rotary, my

slippage like could happen with a wire could cause massive problems if a
hole is .001" in the wrong place, X/Y location is critical in most stuff I

BDI 2.18 includes an abreviated Red Hat 6.2 Linux with

You can go to the following URL, and run what they call Housecall, this is an

up to date virus checker it will temporily load a virus program for you and
then do a virus scan. I have Norton, but still use this about every two
weeks and have been doing it for severals years.
It is a very well know program equivalent to Norton, and McAfee.



Also there is a email letter you can sign up for that will keep you informed
of all the new crap that is being aimed at you. Again highly reccomended.
