Peachy Printer - The world's first $100 3D Printer
I wonder how much error is introduced by the use of the headphone jack to drive the printer - you've gotta deal with line noise from the computer's sound card, mixing latency/glitches from the OS, and the device sampling rate, along with any noise introduced on the audio cable.Does a 3D printer like this not actually require high-precision data to work correctly?
