BrachioGraph – a cheap, simple pen plotter
It's my understanding that higher quality plotters/3d printers/mills' accuracy and precision come from higher quality motors (e.g. stepper motors instead of servos). Will it be possible to someday just put cameras on the plotter which watch the current print and self-correct as needed? That's basically what our eyes do when we write/sculpt/carve.<p>Will cheap motors + cameras + software eventually meet or exceed the quality of expensive high precision motors/controllers?
