Update #9 - We have officially made a plotter :)
Here's just a quick update, we did a few part swaps and have integrated the z axis into the machine fully and wanted to do a test run. Since I'm waiting on a few parts for the filament feed drive, we can't yet print in plastic but we decided to print in ink. So we jammed a sharpie into the print head taped some paper to the print bed and let her rip.
One of the coolest things? Its printing accurately to size, the actual part lines up perfectly to the printed image. Enjoy the quick show!
Thanks to all our backers again. You guys are great!
