Do you have a cnc machine? What software are you using?

Hi, I've got a small machine built and Mach3 installed, but need advice.
My goal is to be able to scan in parts from model airplane plans and cut them on my machine and maintain scale from part...

Hi all
I started building a machine a few years ago and got stalled out on the electronics. Just bought a new setup and got mach3 running. Now I'm ready to cut something and need advice on what...

Hi, I have a new machine almost ready to wire up. I have a 4 axis controller from delagrange technology and am aprehensive about getting it running. I have 140 oz/in motors w/6-wires (unipolar). On...

Thanks Rich
I assume that I could hook up from the step/dir control right from the parallel port and just wire in the 5 volts as in the diagram and make sure the switch is in the 1 position. Any...

I just got 2 ups503-1 controllers from ebay but got no documentation with them. Can anyone tell me how to wire these to accept step/dir signals from the parallel port? These are made by Mycom, but...

Hybidder, if you are willing to do the work, I can probably help with most of the parts, I have cable, pulleys and could even come up with the drum to fit the stepper motor for the drive.(Lots of...

I like the idea of cable drive. After all, very precise accurate movement is achieved with scanners and copiers and they both use cable drives to move the assy.
Just my opinion, replies welcome.

Hi, this doesn't have anything to do with cnc, but I hope that the electronics experts here will help me out.
In my search for good steppers, I tore apart a lot of old copy machines and accumulated...

The miror carriage stepper is usually a 5-phase motor.
If you want to find good 2-4phase steppers, look to the older sorters attached to the end of the copiers or better yet, the older doc feeders...

Sorry for the newbie question.
I have a lot of steppers that only give the amps and the ohms/phase. I used to have an equation that would give the volts the motor is rated at.
Can anyone give me...

Nobody said anything about the motors. You can buy good motors for a cheap price on ebay all the time that would drive a hobby machine just fine.

Hi, I am pretty much of a newbie and I have a bunch of 5 Phase NEMA 23 size stepper motors, 5 and 6 wire configurations, and it seems info is very hard to find info on these. Is it a problem with...

If you are at all interested in renewable energy, build a homemade wind generator such as the ones on otherpower.com and use that power to make your hydrogen. Then any power you get out is good even...

I have many of thier books, and they just came out with 5 more that I will be buying soon.

The hydrogen is lighter and is separated through a bubbler stage. I won't even try to explain the whole process here as there are always the people who think they know more than I do, and maybe they...

BMG Sorry, that board came out of a smaller copier (what we call the clamshell type because the whole machine opens up). That board is not a good choice for a cnc supply because it has the high...

You can store it in regular steel bottles like the ones used for propane.
I hate to sound like a commercial, but look at the books at : www.knowledgepublications.com

If you guys really want to know the skinny of hydrogen and other fuels, take a look at this site: www.knowledgepublications.com
Thi site has material that will tell you in true scientific terms why...

It is easy with a Canon machine. First, l hope that you cut the wires so that the connectors stayed on the board. Then look at the wire colors. Black and white are the 110volt input (there may be a...

Oops, forgot to mention. You don't have to buy from me or anyone else if you can find an old copy machine, they have excellent 24 volt supplies

Great info guys, The power supply is all important, there are people on the net selling learning kits about stepper motors and they use the little "wall wart" transformer supplies for...

Most motors of any kind from copiers are 24 volt motors.

I have a bunch of accuglide slides that are very close tolerance slides. If anybody is interested in a few of these, e-mail me and maybe we can work out something. ([email protected]). I have a...

Gonza. It sounds like you are trying to just power the motor with straight voltage like a dc motor. Stepper motors need driver circuitry that changes the poles in a definate order to make the motor...

Those are photosensors. If you put +5v on one side and ground on the other side, the center pin will go high until interrupted by something passing between the horseshoe that stops the IR beam from...

OK guys, I can offer some info. I have been dismantling copy machines for about 2 years and they are really a goldmine of parts.
Stepper motors are usually in the document feeder (on top of the...

I have a few of these, how many do you want? These are pulls from working copy machines. e-mail me and make an offer.
