I don't have the means to cut out some of the parts, but would really like to build a CNC machine. I've ordered the Hobby CNC kit w/ 3 steppers, and have put in an order for the six foot long acme threaded rods. Today I will order the skate bearings.
The parts I could really use are the ones for mounting the steppers to the machine, and the parts needed for the backlash assembly. I can build the torsion boxes and main gantry with a table saw, radial arm saw, etc.
If someone could help me out, I would greatly appreciate it.

The antibacklash nuts, for example, are very simple to make at home. You need only a tap (thing to cut the threads with) and a piece of plastic from which to make the actual nut.
Since ACME taps are expensive and hard to find, you can just grind down and sharpen a cut off piece of your ACME rod, and use it to chase the threads. The resulting nut will be a tight fit, and more than adequate for a first generation machine.
If you want even better control of backlash, there are some slightly more sophisticated designs that can be used.
Here's how I did mine...and they worked great.
The slit cut almost all the way through allows the nuts to be "bound" slightly, and reduces backlash quite efficiently. VERY simple to build.
Does anybody have STEP files of Joes CNC MODEL 2006
R-2 machine? I am wanting to re-model it in Native
Pro/E. Will anyone export their
Solidworks files of Joes machine to STEP so I can
read into Pro/E and start modeling. Once complete, I will
post the Pro/E models for all you Pro/E guys out there!
first: does anyone have any drawings or something to build a controller for a cnc machine or know where i can get one cheap that works good and if anyone does have drawings or a controller design they'll share can you tell me what i need to build the controller
second: what is a good program to use to make the designs my cnc machine is gonna cut out and how do i take the image and make the cnc machine cut it is there a diffrent program i need for that can anyone help please i have a cnc machine in the works but all the other stuff i'm lost on so any and all information would be greatly appreciated i really need help oh plus what do i use to cut stuff with the cnc machine not the dremel but the tool that goes in the dremel
i was looking at the measurements in edrawings for joes2006 cnc are those measurments correct? some of the measurements just dont seem to add up (for example the ribs on the y axis torsion box) i might just be over looking something if so please point it out. thanks
