GROUP ASSIGNEMENT

Machine design group page

This page shows the group work and the machine made.
In the group, my involvement was to make the machine,
check its operation manually and work with Nicolas on the end effector.

LEARNING EXPERIENCE

During this second week I worked alone on the final assembly of the machine, testing it manually,
testing the motors with Axel, and working on the end effector with Nicolas. .

TESTING THE MOTORS

 We made the connections on the 2 motors, and Axel tested a first move in X and Y with the GRBL Board.



END EFFECTOR

We met again with Nicolas to work on the end effector.
He proposed me to hack a motor of a cd player.
This idea at first seemed a little silly and soon enough I agreed with his idea that proved very effective.
The motor of a cd player is a stepper motor and causes a piece to collide where the laser is.

I observed this piece and noticed that it was easy to fix it.
I removed the plastic parts that hold the axes, enlarged the holes and fixed it on the printed part of the Axidraw.
I used the Dremel with a 3mm wick after marking it.
To hold the brush, I drew a piece that pushed the brush on the moving part, using a bolt and a nut.



So much for my part.



it is Nico's work now...
