Thanks for everyone who has passed their knowledge to the next generation of engineers, your knowledge has helped me in school and to take advantage of the opportunities my engineering school gives...

I see it would only work running in one direction, that sucks I'll have to get 6 wire steppers if I want to use them. How do the drivers compare with geckos?

After doing some research about the operation of stepper motors

How Stepper Motors Work

I think if I connected +A lead of the stepper motor to the driver and the A- to the other two open slots...

So no to the hobby cnc driver, I went to my local used electronics seller and saw a set of 3 amp vexta 2120 drivers for $40 a piece, does anyone know anything about them. If they are good I can go...

What about hobby cncs?

I'm fed up with my second tb6560, just yesterday my x-axis started losing .1'' every 10'' it moves:violin:. It could be the motor but more than likely the chinese driver. I want to reuse the bipolar...

Guys, I like how there were a bunch of ideas you came up with: titanium, unobutainium, epoxy granite, cast iron, and aluminum. So in essence the two best materials are epoxy mixed with anything else...

So I was thinking if I ever became a millionare one thing I would do would be to build the best Cnc machine ever:cool:! So I started thinking about characteristics I wanted and of course speed, what...

Because it is a high lead, screw and will be turning at high rpms this nigh affect things a little more.

Jaws of life?:p

I would get a t slot router bit and use that, if you want grind the bit to have a corner radius.

Are you going to be working in metals, if so gets Cnc taig. If not, a microcarve with a xylotex or gecko controller, would do just fine.

Here's a rendering of my design I'm working on the saddle, and I changed the spindle by using angular contact bearings inside a turned aluminum housing.

I took a look at these angular contact bearings, I see that they are mean't for radial loads so they should do better.

I'm thinking of making a diy benchtop mill, so I started in CAD with the spindle. I made a simple spindle with pillow blocks, and an er25 collet, and a 1hp motor. Will it be solid enough for milling...

Microcarve sells his in different sizes, they are aluminum construction and very rigid.

Congrats on your first post, welcome to the zone.

So guys I'll try the sub project checklist, we could probably assign sub projects to members that they can work on during the summer. But its...

Here's some pics of the cannon, it fires small projectiles using the pull string charge from a dismantled party popper. I also posted some pics of other projects, my DIY Cnc,compressed air automatic...

:rolleyes: Well that's one way to do it, probably would work well.

Hey txcncman where in tx are you from?

Ok first off Is like to thank everyone who responded for taking their time and sharing your knowledge. One thing I should have told you guys is that I'm in the schools solar car team, today I...

Well then guys I guess I'll try not to burn myself out in High School and hit it hard in college:D. I'll still try at the many "fun" engineering opportunities my school offers, because you guys make...

Thanks for your response, this has really given me a feel for what I'm up against. I took a look at khan academy and want to use it during the summer to test out of algebra 2, then go straight to...

Hi, I'm a freshman in hs and I'm planning on becoming a me, I have a few questions about the career. What do you spend most of your time doing? What softwares do you use? How easy is it to find a job...

Glad to here that, didn't know they had a 1/8 also I guess I just haven't seen it. Louie, I didn't know that straight bits worked better, I actually find that they heat up faster. One time I was...

The only way you could come under $1000 is if you got a chinese tb6560+motors+cables+power supply kit for $200 and a HF router, but as soon as you build your machine you'll want to upgrade.

For 1000$ look at solsylva plans and you should be able to make a good machine with access to basic tools. For people who already know how to use CAD software, adjusting to CAM and making toolpaths...

Nice design, does it also come with a driver board or just the motors. What diameter linear guides are you using?
