You have done an excellent job. It seems to work very smoothly. A great machine to get into Cnc.

Thank you!

I have a lot to learn, but I'm certainly addicted. I have been working on my code writing, in the video I have a lot of unnecessary and redundant machine moves. I have reduced my cut time dramatically just from experimenting.

I think I have less than $200 into the machine....including electronics. I also designed and built it rather quickly...less than 2 weeks, after work.

Nice build! That's a good arrangement for getting reliable motion from drawer slides.

One weak point looks to be the use of a single narrow rail for the Z axis, that's a lot of side leverage there on that narrow rail. I would be tempted to screw a flate plate of wood to the Z structure, then use 2 drawer slides for Z or 2 rails/rods of some type.

And maybe lower Z a little bit, to give you a bit more rigidity to cut out flat stock as being "addicted" I'm guessing you will use this machine to make parts for the next one...

What are the details of the electronics ?
You've built yourself a very cool unit for $200.

I have the TB6560 driver ($22), a 12v power supply ($12) off ebay and small 5.3v/ .75A stepper motors ($10).

For the computer running the whole deal, I used a HP Pavillion 503n I had laying around.

How do you guys wire up everything? I want sockets on the cpu case that I can plug the steppers into, so I don't have to drill holes and use grommets. As you see from the pictures below, I need to clean up the wiring.

I was thinking the same thing about the Z, but turns out, it's the strongest axis! The part I need to make is the router mount itself, as you can see I have a pipe clamp and some wire holding it on.

And yes, It's already cutting parts for the next machine....

I love it!!! Well done and don't worry about cleaning up the wires....

Thanks!

Even though it doesn't look like much, I still want to clean up the wiring so It can be more mobile. I still need to build a large base/cabinet for it. I'll post some pics after I find some 6 pin sockets and plugs...

I like it!
Most of it appears very simple...cut and dry!
What did you use to drive the steppers and where did you obtain them?

Take a look at this for a cheap $29.99 spindle choice;

That will be easier to mount than the Dremel and a much better functioning spindle.
