After some false starts and puzzlement, I achieved success with the new Da Vinci!
This is an example of the Key Chain sample print. It took 34 minutes, and 3 meters of ABS plastic filament to make. I’ll note that here for reference.
Now that the device is up and running, I will try a larger sample print before attempting to upload some of my own designs. Fortunately, a freeware drafting program called OpenSCAD should allow me to design some of my own parts.
The work envelope for the printer is only 7.8 inches cubed, so for large constructs I would have to print out smaller sub-components to be assembled by hand. Since most of my existing stock consists of small items, this should suit my purposes for the foreseeable future.
