This week exercise is a group exercise where we are making a machine. You can head towards our group page

Machine that Makes
During initial discussion and brainstorming session, all of us participated. We had discussed several possible ideas and finally settled on an idea of making 3 axis machine which can draw on a sand.
I had decided to participate in a project in every possible way so as to get hands on every skill. We had started designing a machine using Solidworks. Where my friend Clement had designed most parts of the machine.

Final design made by Clement Burga
I along with my friend Amol Wadkar had worked on assembling these parts.
Box Nut Sub assembly
We had started doing assembly of lasercut pieces together press fit. We made box nut assembly. There were 3 such sub assemblies which we made
Guide bush 3D design and printing
To make smooth sliding motion between guide rods we had 3D printed guide bushes using PLA. These also serves purpose where in case of wear we can replace bushes.
Motor Sub Assembly
Slide Sub Assembly
MTM Module Box
MTM module assembly
Y axis sub assembly
Transfer holes reference to box nut assembly
Design modification for quick change
Design modification for quick change
Hole here is modified to form a Slot within which screw can slide and fix
Top hole increased
Top side hole is increased so that screw driver can pass through it
This is how its assembled
Z axis found not moving
At this point we found that slide is getting locked even we have assembled everything. No matter whatever clearance we keep no matter whatever force we put to rotate lead screw. Axis just locks
Before : its locking
No sliding. This is not expected
After : its not locking
It works. Smooth sliding. This is expected
Semi final sub assembly
Notch made at guide rod ends
Modified version with pen holder
In modified version I have designed a pen holder. Where pen can be pressed to hold it perfectly

Z axis with pen holder and pen mounted
Final Machine Assembly with pen holder fixed
How did we made it operational ???
