Possibly Arduino Controlled CNC
We are going to try using this later down the line
Initially we were worried about making the 1D CNC machine out of cardboard. We knew that we wanted the machine to be rigid, clamp-able, and possible strong enough to be tinkered with over and over again. With that in mind, we set out making our CNC machine out of MDF.
The dangers with making something out of a rigid material lies in tolerance and precision. In order to guarantee perfect hole precision, we used a CNC Mill to cut out the pieces. Everything was ready to go, until I broke one of the side planks (more on that later)
If you would like to make our version of the machine, HERE are the CNC Files!
Now, on to production!
It’s really important to test the construction before you glue anything (I almost attached the carriage side walls upside down)
Even with our precautions, there was a little bit extra friction than the stepper motor could take running off of the power supplied by the USB
Now for the fun part!
Wire your arduino uno and breadboard like they do HERE
and with this diagram
We wanted to test out our arduino code skills a bit and try something fun. It was simple enough to change speed, or length of travel, so we wanted to add one more variable, a Switch!
Updated Arduino Code (this new code has way less feedback on the limit switch)
We needed to figure out how to use this interestingly, so we decided to mess up the 2 axis plotter, and make a different type of 2 axis plotter, where one axis is controlled through arduino code, and the other is controlled through the plotter, but they have a relationship.
1.Hacking two machines together is really really fun
2.Clicking limit switches is ungodly satisfying
3.Machining things needs to be perfect, or else inaccuracies are played out very quickly
