This week’s accomplishments

• Wrote, edited, and formatted the design report. Specifically, these were my responsibilities on the report:
  • hardware architecture
  • Introduction
  • gantry subsystem implementation
  • water heating and distribution subsystem implementation
  • scale subsystem implementation
  • risk mitigation
  • BOM
  • Formated, edited, and submitted the final report
• Attended mandatory lab
• Pump flow and current testing
  • will need to test further to fully understand the relation between current and flow rate.

Next week’s plan (spring break)

• Will be traveling, so I have limited time to work hands-on with the project
• However, will be looking to successfully run OctoPrint on my personal Rpi to communicate with the 3-D printer
• Experiment with different flow rates (and how much current each rate requires)

Status Report: On schedule

This week’s accomplishments

• Ordered parts for the project
• Attend and critiqued the capstone design presentations on 2/19 and 2/21
• Began writing portions of the technical paper for this project. Focused on how to smoothly integrate OctoPrint with the Ender-3 3D printer. Will need to decide if we should lock the z-axis movement of the printer since we will only need movement in the x/y planes to pour the water. However, it may prove to be more complicated to do so.
• Flashed my personal Rpi with OcotoPrint to begin experimenting with the gantry’s movement at home.

Next weeks plan

• Begin constructing and setting up the 3D printer
• Begin experimenting with Ocotprint
• Write the technical report

Status Report: On schedule

Personal accomplishments

• Contributed towards creating a bill of materials
• Finalized the materials needed for the gantry. As mentioned in this week’s team report, our team is approaching our machine with this mindset: “If a reliable solution currently exists, why try to reinvent it?”. So, for the gantry, decided on repurposing a 3D printer. To communicate with our Rasperry Pi, determined that OctoPrint, an open source 3D printer controller, would be best.

Next Week’s Deliverables

• Will begin ordering many of the required materials on the BOM
• Will begin reading and creating notes on the 3D printers user manual to understand how to best integrate it into our coffee machine (including how OctoPrint can/will interact with it).

Personal accomplishments

• Finalized the slide deck for the proposal presentation
• Presented the team’s proposal slides and fielded questions regarding the project
• Read and analyzed feedback from peers and mentors regarding the quality of the presentation
• Began researching gantry solutions (specifically, what needs to be created vs. what already exists)

Next Week’s Deliverables

• Create a list of components that need to be ordered for the gantry
• Research and save essential resources I’ll be using to guide the gantry’s creation process
