Last modifications done

The issues found with bogies falling off of the corners have been solved. We added another 1/8" thick stock to the curve.  This helped the bogie stay level with the oncoming lower track and transitioning was a lot better. Picture shown below shows the added thickness. Also finished off with adding the rest of the thicker U brackets.  Had to drill more holes and countersink.  Track is finally done for the semester and all that is left is Maker faire and last presentation which is coming soon.  Second picture is the track completed.

 

Back to Printing

I was able to replace the thermistor for the printer.  Have six more thicker brackets to print so we can start installing on the other loop. These brackets add extra support where the individual track pieces meet up.

Thicker U Brackets

We decided to print out to double the thickness of the bracket.  Instead of 1" thick, we decided to go with 2" to help the the separate pieces that will link up. We would need 12 of these thicker U brackets. Unfortunately, my 3D printer ran into an error.  I had to order new thermistors to replace the one that is on the heated bed. Now it is a waiting game to wait for the new thermistors to come in.

Issues Found During Paseo

We had found other issues with the track. When the bogie goes through a corner and onto straights, the bogie has to fight up an incline and makes the bogie work harder. You can see it slightly in the picture but the bottom rails are not sitting  leveled to each other.  To accommodate for this problem, I designed a relatively  quick solution shown below.  This will help guide the wheels up so the bogie will not have to climb up a high incline.

Last Presentation for Class

This week was a slow week for us. After Paseo Prototyping we broke down the track then the next day we put it back together so that the APP and Positioning team can work on the track.  Also worked on the presentations and presented on Wednesday.

Paseo Public Prototyping

This week is the week of Paseo Public Protoyping. Saturday morning I came in to set up at the event.  Once everything was set up we got bogies up and running. The bogies ran pretty smoothly except we were only able to run two bogies at a time because of some issues.  Bogies would eventually run into each other and cause some issues.  There were some other issues with bogies falling at corners of the loop. So we will have to look into that and find a solution.

Ready for Paseo Prototyping

At this point, we are doing final touches to get ready for Paseo Public Prototyping.  We ground down some imperfections on the track.  Some of the U brackets extended above the lower track so those points had to be ground down with a Dremel.  Break down has been done for the track and ready for transport the morning of Paseo Public Prototyping.
