Group Assignment:

  • Do your lab's safety training
  • Test runout, alignment, fixturing, speeds, feeds, materials,and toolpaths for your machine

Individual Assignment:

  • Make and test a microcontroller development board that you designed
  • Extra credit: make it with another process

  • Group Training

    The group project was carried out at the UNCP Fab Lab. We used a small CNC-PBC machine in this lab. Initially, it presented some problems, such as looseness in some of the engine mount bolts. We had to make some adjustments and also install the finest 0.1 mm and 0.2 mm cutters. We then used the CNC milling machine and performed some initial motion tests.

    Individual assignment

  • Build and test a microcontroller development board that you designed
  • Extra credit: do it with another process
  • List of materials to be used.

    View of the PCB components

    • The 3D view shows the PCB electronic components.

    PBC plate editor in KIDCAT

    After showing the electronic components that make up the board, the PBC board editor is shown in the Kid Cat software.

    Schematic editor

      The graphic shows the microcontroller PCB schematic editor.

    3D viewer

    The graphic shows the 3D Viewer of the PCB design.

    software FlatCam 8.994 BETA

    FlatCAM es un programa para preparar trabajos CNC para la fabricación de PCB en una fresadora CNC. Entre otras funciones, puede tomar un archivo Gerber generado por su programa CAD de PCB favorito y generar código G para el enrutamiento de aislamiento.

    G-code editor

    Next, we need to generate the programming G code. To do this, we use the G code editor button and proceed to save it to a file.

    G-code track

    In this window you can see the G-code track, the card measurements, the layout, and the start coordinates, which is ready for printing the designed card.

    Plate to be placed on the PCB

    Here is the plate to be placed on the PCB.

    Board fixed on the PCB

    The image shows the board fixed to the PCB, it is held in place by 04 fasteners to prevent the board from moving.

    Printing lines

    In this process we can verify the printing lines that the PCB is making.
