Has anyone tested the current draw on 110V for the entire system? I'm presently throwing wires in my walls and anticipate buying one of these 6040 machines in the future but it seems that they would...

I wouldn't necessarily classify rotating nuts as "more expensive". For example, with a servo system, to switch to rack and pinion will usually require 1) two racks 2) two motors 3) a bunch of gears...

Coherent - I'm sure there would be plenty of interest in seeing your setup. I don't think I've ever seen the W's in anyone else's projects so far...

The Micro-mark is retrofitted with a different scale on the X and Y leadscrews -- .05" per turn compared to the .0625" (1/16") of the competitors. Whether or not that's an advantage is debatable, but...

It's a difference in the shape of the carbide teeth on the blade. The two basic types:

Alternate Top Bevel (ATB): The tops of the teeth alternate with an approximately 30 degree angle to the right...

CNCAdmin: assuming you have root access to this web server, since you're running Debian you can do:

apt-get install pstoedit

The pros are all in the method illustrated by the first example and is the method that the bearings are really designed for. The proper documentation on the specs of linear bearings should be...

Basically it's just an adjustable toolholder. Item #39 is a replaceable collet for holding the tool (which can again be indexed/rotated). Fig #5 is the same device but using a rack and pinion for...

What's the new G204 drive (what are the new features)?

I think the answer you're looking for is that it cannot be used with Geckodrives or pretty much anything else that won't break the bank. These types of motors (brushless) require a controller that...

This posting is completely false. Rekd is correct, it is illegal to make such calls to a cell phone.

CNCAdmin, you can read up on this hoax at snopes.com.

With dual leadscrews or timing belts you could similarly avoid the torque. I think they're just noting the fact that there is not a single rack which could cause the torque.

Notice in the design...

Your friend is correct. Twist the black and white together and then attach to the resistor, and then the other end of the resistor to the board.

The diagram you have is demonstrating the...

Since it's designed for a wheelchair it's quite likely designed to rotate faster in one direction than the other (to make reverse movement more controllable).

Is it too late to vote for the Bosch 1617? A woodworking store had a display demonstrating the size of the stators of various 2HP models and the Bosch's was clearly beefier. Well, it's also more...

If the shafts of the two motors were linked and only one encoder was used, this would work (to an extent), wouldn't it? Perhaps a timing belt synchronizing the two motors in this instance.

If you're still thinking about chucks you might consider one of these from Grizzly. They run under $40 and you can fairly easily build some large flat-faced jaws for a better grip on the wood.

If you state your goals as to what you're trying to cut and how much you DO have to spend then I'm sure many people here could give you an idea as to what your possibilities are. Also, there's a...

Bandsaws less than 14" are fairly ineffective. Also note that most blades you find in stores will dull quite quickly with aluminum -- expect to pay around $17 per blade for anything with any quality...

I would think that the moment of inertia of the spool would create some discrepancy in the measurement, so the weight does matter. I'm also not sure how you figure that "half" the weight of an...

If you put a 2" diameter spool (1" radius) on the shaft and use it as a sort of "winch" to lift weights, however many ounces you can lift is the definition of the oz/in rating. I.e., 300 oz/in is the...

I'd assume that "birch" plywood implies "baltic birch" plywood which is a vague term for high quality plywood. True baltic birch plywood would come from Russia (as the name implies) but has a...

You lose the total width of the (whatever) sliding on those rails, measured from the outside of the bearings on that rail. So if I have a 5" wide slide and want to cut 10", I need 15" long rails.

I'll bite -- how are you using serial with the xylotex driver?

Why did you ditch the IGUS products? Which IGUS product were you looking at, specifically?

I'd look somewhere other than at the steppers in a floppy drive - assumedly quite weak and my experience with them leads me to believe they have a fairly huge degree turn per step. Most surplus sites...

It gets clumsy spinning long rods (ballscrew) and I believe the largest diameter rod you can put through the headstock is 1/2". With proper homebuilt steady rests it can be done, but it's a heckuva...

Just throwing in my 2 cents...

1) Push on the shaft of your stepper - many (all?) of mine have about a 2mm give to them. Aside from bearing wear this little bit of play is undesirable.

2)...
