Last to last week went by fabricating the Proof of Concept Prototype of our Wood Carving Machine,followed by a 3d model of the same so, this week we decided to move with the final Design and Prototype of the machine. After doing a lot of brain storming and after going through with various iteration of rough design, We worked out a new design in sketches and thereafter distributed the responsibilities among us. Not having a strenght in electronics and embedded programming, I took that part of the machine as my responsibility. This will help me learn new things than to do a task am already familiar with like 3d designing.

SO the Majority of my contribution began once the design was finalised and Jatin very nicely translated all our designs into a 3d form. It started with laser cutting the parts and this part is interesting-it was cut from all the waste boards of vigyan ashram,(not new boards), each and every cm was utilised and we finished all wate boards , scavenged it to the inch. I was happy that i could prove that i now understood the machine well enough tonever waste material while printing. Its also a good way of having others notice and integrate it within their print philosohpies.

Day 52 -->



The initial plan to use a fabnet Board to control 3 stepper motors failed due to unavailability of components required for it in India. So we had to leave this too midway in addition to the stashakit and use an arduino along with motor drivers to make this work.
We were given lectures on 'C' at Vigyan Ashram from externals and other peers experts in C @ Kochi, Pabal and Pune.

Assembled Machine

We did change the end effector and removed the turntable later

Following are the steps to connect a servo motor to the Arduino: The servo motor has a female connector with three pins. The darkest or even black one is usually the ground. Connect this to the Arduino GND. Connect the power cable that in all standards should be red to 5V on the Arduino. Connect the remaining line on the servo connector to a digital pin on the Arduino.

This is important :
Our objective for making this machine was to make it a 3-axis Wood Carving machine, but as we finished everything of in the machine like Assembly testing the X-Y Axis movement, then figuring out that we were still lacking behind in the End Effector to put in our machine as we were not able to procure any specific Tool Holder and even any good Motor to used for Tool Movement.
With a constraint in time, I hit upon the idea to install lights or laser-decrease my DSLR's camera's Shuuter speed to about 20 seconds and capture the movement. It is very similar to a SLS x-y movement. Only that this time tha camera catches it in batches which i manually stiched together in photoshop to form the image with light which i gave it in .

Before we started this, I was asked to provide the proof of concept as it was difficult to understand what i was talking about and this is what i quickly demonstrated with a shutter speed of 10 seconds




We used GRBL Fireware for operating the X-Y Axis and fed it with a G-Code of a 2D design through G-Code Generator, the Torch or Laser attached on the Y-Axis moved and traced the 2D design feeded to it with the motion of the Laser getting captured..
