Let us step into the future of festive artistry with this latest project! In this project, I am turning a 3D printer into a Rangoli Plotter, as you all liked the earlier one where I had turned the same into a pen plotter. Imagine intricate rangoli designs coming to life effortlessly. It's the perfect blend of tradition and technology, creating a celebration that's both mesmerizing and modern. Let's light up this Diwali with innovation and color!

A few years back, I showed how you can draw on paper using a 3D printer, basically converting your printer into a 2D pen plotter. You guys loved it a lot!

Now, on the occasion of Diwali, I got the idea to use a similar approach to draw Rangoli with it, not a complete one with colors filled, but just an outline would be a great start.

The plan is to replace the extruder carriage with a mechanism that can dispense rangoli powder. The problem with this, unlike pen plotter, is that it should have some way to turn ON & OFF the flow of rangoli powder. There are no spare I/Os available that I can tap into. However, since we won't be using the print cooling fan, I decided to use the commands meant for the fan to control the dispenser.
