Hmmm... what I see, is 2 y axis steppers, one z axis stepper and no X
axis stepper.

Okay, I'm being a dick here... but for me, I operate the table from
the end, so the long axis is Y, the across axis is X.

I do have another settings file which flips everything 90
degrees...but my brain doesn't work that way..for some reason.

I have said this before... I don't think like other people. G

What Greg said, and I've had good experiences with

http://www.hobbycnc.com/products/hob...oard-packages/

I have their 4-axis package with their 23-205-DS8 steppers and like it.

Hey Morris, don't chew me out. I barely know what a 2-axis stepper
does. I'm guessing a 4-axis model adds a few more directions to that
equation.

Oops - sorry, I wasn't chewing you out. They caught me by surprise by
offering to sell a four motor plan set right beside a three motor
package. Fried my calculator, so to speak.

Thanks for the link, I'll check it out.

By the way Morris (and Robatory and anyone else who wants to take
part), I'm going to be picking your brains while I build a list of
what to buy. And then, you can tell me what to add or subtract. That's
after some considerable discussion.

Ok. Might be a good idea to lurk a bit on the CNC metalworking group -
those guys have a lot of good experience and occasionally post photos of
interesting projects (for example: a cnc-milled steel boob for a bra
manufacturer).

Be warned that this CNC stuff can make you lose sleep, think weird
thoughts, and twist your sense of humor in strange ways. If you haven't
seen the video of robatoy's chicken spinner, you should. I, myself, have
kept most of my marbles in the basket - but I'm still working on my
weapons-grade CNC pie thrower...

Which begs the questions: "What kind of pie?" and "How far?"

I'm surprised jo4hn isn't doing the CNC boogie yet. He's used to
talking to parcels full of electronics from far, far awaaaayyy!

Understood and knew all that. What I showed may have only covered
25%-50% needed parts list. What I really want to know is if the type
of stuff I did link too were of sufficient quality to begin build what
one would consider to be an above average CNC machine. Guess the
question should have been do these parts qualify as a really decent
starting point or should I be aiming higher?

I find these places helpful:

As Greg pointed out, you're nowhere near done by buying that kit. The
rest really adds up in a hurry.

Looks like a nice unit, but I'd prefer to build one myself considering
that all the parts, pieces and documentation are available. It's the
best way for me to learn.

No problem, do that already.

Don't have one as many people here will attest to.

You mean how to create a CNC built pie trebuchet?

Both. So far I have been lucky to get paid for the challenges I have

You're being improperly modest. Do you still have the photos of your
backlit inlay work? Would you post a link, please?

Wow! No. ;-) I was speaking of v-grooved and filled piece with LED
backlighting.

That lithophane looks pretty good, tho - and I think you snuck in a
sawhorse drive-by.

Au contraire, mon frère. That saw-horse is a Triton which I mini-
reviewed quite some time ago.
I dunno how I lived without it. Handiest thing ever. Handier than a
bag of potato chips, handier than a pocket on a shirt.

3HP spindle on a 1/16" ball nose bit. 2"/second feed rate. That gets

The goal of this experiment was to get acceptable detail at fast
cutting/feed rates. Detail can be increased by smaller step-over
rates.
I'm reasonably satisfied.

After cutting, I coated the stone with FrogJuice. A clear coating out

That is impressive. And you can increase the detail? Amazing. My wife
would
love it. .......... now ...... will I show her or not? ........... : )

A question; I have no idea what size the coin in the last photo would
be, -
could you post the diameter as a reference?

diggerop

It is a quarter. 0.94" or 23.88 mm if you're so inclined. *S* I
haven't worked it out in microcubits because my calculator ran out of
yak oil....and without yak oil, my yak won't work the treadmill.

I just sold a couple of desk name plates to be carved out of soapstone
for two executives. (I didn't really want to do this for those pompous
*******s, but when I said the price, they said..ohh..okay.)

Good on yer. : ) ....and thank you

[ two! two! two! ...]

[ three! three! three! ...]


Heh.

I keep going back looking at your bot. It fascinates me. However, I won't
try to build one. Too many projects on the go now and too little time. (How
come I then spend so much time writing drivel and posting it on the wreck.?
A recently aqquired medical condition, that requires me to be seated for
treatment at 4/5 hours every day - temporarily, I hope.)
I thought about buying a mini version, but it would really be just another
toy for me to play with. Got far too many of them as it is.

If I could think of a reason to use it commercially, perhaps providing
employment for somebody, I'd go for the idea. Brilliant machines.

Rob,

You bags came to the store instead of being drop shipped. I cannot remember
your last name or company name to contact you (DOH!).

Please call the store.

We entered those into inventory last month.
Besides, if we hadn't had them by now, either you or the fine people at
Fein would have heard by now LOL
But if they're 'extra'...well then..
