Wound up w/ a second ShapeOko (a 2, which I got so that I could write the instructions at http://docs.shapeoko.com/ ), so have been planning to turn it into a 3D printer.
The initial (naïve) plan was to just mount an extruder I'd bought, source a hot-end, connect it to a spare stepper driver on my AtomCNC board, reflash w/ Teacup or Marlin and print --- anyone who knows anything about 3D printers can quit laughing now.
The current plan is:
- mount an extruder (a Wade's reloaded)
- wire up a hot-end (a J-Head Mk V or so w/ 0.35mm orifice for 1.75mm filament)
- source a new Arduino (an Uno w/ just a 328p won't cut it)
- source a stepper shield which has 4 stepper drivers (one for each axis, one more for the extruder, plus electronics support for powering the hot-end and monitoring its temperature)
Still haven't decided if I'm going to buy a heated bed or no --- hoping to manage w/o one ---you 3D guys may quietly laugh again now.
Unfortunately, there wasn't as much in the way of documentation on the RepRap wiki as I'd hoped for: http://reprap.org/wiki/Categor...
So I'm documenting things here: http://www.shapeoko.com/wiki/i...
