This past weekend I was fortunate enough to be able to demo my MPCNC build at MakerX in Columbus, OH. I used a thin-nib sharpie and pre-setup gcode files to draw about 10 different images. I passed out the images to those that wanted one.
There was a pretty good turnout - around 1,500 people. Around 10 or so of the folks I spoke with knew what an MPCNC was (had seen one or had built one). Many were surprised that a 3D printer would be able to provide so many of the parts and were impressed at Ryans design skills.
A decent number of people took a picture of the card I had printed with links to the V1Engineering website and Thingiverse QR codes so I expect some of them will join the fun here!
