Summary update: http://www.thingiverse.com/thing:895579 I recently completed a fun project in just two days, culminating with the finishing touches on my 3D delta and its calibration. After printing a few test objects, I decided to experiment with light painting by attaching an LED to the printer's head. The LED is connected to pin 1 of the Ramps' servo port. Marlin has a useful gcode extension (M42) that allows toggling an Arduino pin on or off. I utilized this feature to switch pin D11 on and off. The next challenge was creating custom g-code to achieve this effect. To overcome this obstacle, I employed Grasshopper3D to craft a script generating simple G-code that creates lines every 3mm within the model. Water-tightness is not required for this method. For simplicity's sake, I kept the feed rate constant at 3500, which is suitable for the 3DR printer. I even experimented with dashed patterns but found it only visible in the Fox model. The next step involves incorporating a RGB LED to introduce color into the process. http://vimeo.com/97840567 http://hackaday.com/2014/06/11/dslr-gives-exposure-to-3d-light-traces/
