I have officially joined the CNC revolution.
The gcode for this wheel was provided by Glen's CNC Corner (no affiliation) and it was available free of charge.
|Styrofoam wheel and original scrap styrofoam|
I used a scrap piece of styrofoam. Both to test the gcode and my machine. Surprising enough it seemed to work the first time. There is a spot in the gcode to turn the material over and continue. And, if you look closely at the first image, you can make out an uneven edge. This was NOT a problem with the gcode, it was where I got the hose to the vacuum cleaner wedged between two moving parts of the gantry.

ShapeOko #329 showed up on my doorstep June 18, 2012.
The kit was "Mechanical" only as I already had motors and driver boards.
I decided to engrave the serial number and date on one part of the gantry. I reproduced this part out of thin wood panel. I used Inkscape to create the lettering, and then with the help of a plug-in called gcodetools I was able to generate the gcode.

No, really, that is a 9" piece of 2x4 that I anchored everything using drywall screws and a couple plastic bottle caps.
|EasyDriver driver boards for 3-axis control|
EasyDriver boards were purchased through SparkFun. The rest of the parts were gathered/salvaged from parts I collected or from the local RadioShack.

On the software side, I have a dedicated computer with the LinuxCNC operating system. The computer is Dell precision 360 and seems to be working fine.

Here is the first piece I made using my CNC machine.
So... what am I going to make with this machine?? I am not sure. I think I am having too much fun trying to make everything work, and I have not given much thought to a final project. My hope is that I will be able to make anything that comes to mind. Or maybe it's the old "Dog chasing a Car" ?
