Love the enthusiasm, guys...but I don't really want to totally re-engineer this board.
I am, however, open to the idea of an interface board, like one of the cheap Chinese ones. An extra $15 or...
Thank you. Most helpful. And, that's why I bought only one of these boards...experimentation.
I was thinking of wave drive, direct from the parallel port, for 2 axes. As I said, absolutely...
I already won one at $5.53, and buy it now is usually around $7. I'm happy to experiment, but would appreciate feedback from the community. What do you think of the board? As a basic way to make...
Hi, guys. It's been a long time, and I'm *baaack!*

Got a question for y'all. I found a whole series of...
I just looked at that site, and it looks promising. There is a connector pinout for a parallel to floppy cable, that basically says I can do exactly what I had heard.
Notice, specifically, pins...
I remember, a few months back, seeing a post on either this site or DIY-CNC, stating that a floppy drive had a driver circuit built in. Fair enough...it would have to have one.
But, I also...
You seem to have missed the Solsylva plan (advertised on this site) as a point of inspiration. He has a relatively ingenious bearing truck and supported rail design that could be easily fabricated...
Go to your local hardware store and go to the aisle with the nuts and bolts.
Grab one in 1/4x20 and screw the nut onto the bolt. Now, "rock" the nut back and forth. Feel the wiggle? That's...
Me too. :)
Here are some more examples -- some are slightly less expensive, but still stratospheric. I want to be able to do this to my own watches.
To that end, I'm working on converting a micro-X-Y...
RGM -- I know Roland. He's on that same collector site. His watches are exquisite...and yes, that is the proper term. They're way beyond magnificent...they're exquisite.
I have a few 100+ year...
Basically, it's one of those where, if you have to ask, you can't afford it. :( *I* had to ask.
RD watches cost in the neighborhood of $10,000 and up to as high as you can count. I can't seem...
This type of thing puts a twinkle in my eye, too. The detail, the elegance, and even the sound it makes harken back to a more elegant time.
The very reason I collect fine watches -- but mine...
What would you like to know? How to build one...where to buy one...what the design requirements would be?
If you could narrow your question, it would be helpful.

Well, you did say you needed it to be precise, and you had a budget.
The mini mill at Harbor Freight is about $300US if you wait for a good sale...not far off the price for a router, in your...
I think he answered my question, while I was writing my post. They're only separated by 11 minutes or so...I use a multi-tabbed browser, so that's probably what happened...he answered while I was...
Trust me...it's flat. Watch dials are comprised of flat planes...sometimes 2 or 3 of them stacked, but they're always flat.
Look where the arabic numerals are attached...flat.
The decoration...
It's machined. Here's a pic of the whole watch...

Actually, it's not cast at all. Roger Dubuis watches are extremely expensive...and are actually cut using a rose engine. Amazing detail...available for an extremely high price. Not a bad value, as...
It all comes down to precision and repeatability.
Notice I listed them separately...they're not the same thing.
First, let's talk about the router. If you look on eBay, you'll find a seller...
I think this is an ideal application for the V-Carve software, but I'm not sure. Thought I'd ask.
I love beautiful watches and clocks -- and this dial is particularly beautiful. It is this type...
HP Laserjets have a single 100oz-in stepper motor in them. While I've not heard of anyone using the circuit boards from them, the control electronics to control a motor of this size are obviously...
I look forward to the results. I suggested using the same router, a while back, and was told it wasn't good enough.
I'm looking forward to seeing "them" proven wrong! ;-)

How bad is the runout? (how "wobbly" is the bit when it's in the chuck?)
When you try to cut a straight line, does the resulting cut wobble all over the place?
The Harbor Freight unit looks...
There's no inherent reason why a DIY machine couldn't machine chunks of aluminum -- just build it MUCH stiffer than what we usually build on this forum.
Bear in mind, despite talk of being able to...
Servos and steppers are *very* different. Let me try to explain.
Servo motors are just DC motors. You apply a voltage to the terminals, and they turn. Their motion is controlled by another...
Though I've not built it, I agree that the MechMate has a lot of potential. Having looked at their plans, they show a lot of detail and include a lot of nice features that should result in a well...
Take a look at the JGRO design. There are even free plans available, on this site.
Thoroughly tested, and proven -- and well designed.
If you don't mind paying (a fair price) for some plans,...
Energy chain is a term used to describe the segmented flexible conduit thing that he houses his wires in. If you look in his second photo, you see that white "chain" looking thing? That's energy...
