Final Project summary



We came up with this project by listing some ideas and pick the best one. We went to homedepot to buy some wooden frames. We took the correct dimensions of the assemblies and where to drill. Then we built the X-Y frames. We struggled a lot with coding the Arduino. We completely finished our project right before the expo. We tested our project in the first 10 minutes of the event and it worked. We draw a triangle and some lines. Many people liked what we did. The code that we used for the project can be found here. Also the piece we 3Dprinted and laser cut are here. The completed assembly could have been improved by laser cutting the guide-rails and making the tolerances tighter for the slide bushings, which could have been done by either 3D printing parts as well as laser cutting others. Moving forward it would be nice to have some extra time to improve some of the basic movement and overall design of the project. Overall, the expo went very well and we all are very happy and surprised about the ability our project performed

here is the final cnc X-Y plotter

Outer Frame Complete!

After many hours of sanding by hand I got the frame pieces where I would like them to be. I'm pretty happy I can feel my fingertips again too.

Partial Assembly

The frame has been measured and cut out just need to nail and screw all the piece together then we came began testing

X-Y Axis slide and rails


X-Y slide bushing
The bushing is made from two 4" pieces of 1" PVC pipe then I filed a flat spot into each one in the middle to allow for good adhesion with the epoxy. The nails in the scrap wood in the pictures below are the jig I made to make sure the two pipe sections were 90 degrees from each other.

threaded rod with a slide rail attached 



 
X-Y assembly 
Here is the X-Y assembly which will have a frame built around it as well as having the motors attached to an end of each section of threaded rod.

Baseplate

This is the baseplate tat we are going to use for the mounting of the hardware for this project. It measures 18"x19", recycled from an old laser printer.

Stepper Motor Mounts



Here are two prototype stepper motor mounts. These are to be either cut out of wood or laser cut out of acrylic.
