Assignment

Group Assignment:

• Characterize the design rules for your in-house PCB production process
• Submit a PCB design to a board house

Individual Assignment:

• Make and test a microcontroller development board that you designed

PCB - Cube3D MxPro

After completing my PCB design in KiCad, I exported the Gerber files. For the manufacturing process, I used two software programs: Cube 3D Cam Pro and UUCNC.

Cube 3D Cam Pro:

I imported my Gerber files into the software and selected the appropriate layers for each process:

• Top Layer: Used for engraving (F-cu.gbr, gtl)
• Mechanical Layer: Used for cutting the board edges (Edge_Cuts.gbr, gko)

Once the correct layers were selected, I generated the necessary G-code files for both engraving and cutting.

UUCNC:

To begin, I installed the milling bit and tightened it securely using wrenches.

Next, I set the machine’s origin using the following steps:

• Clicked Reset
• Selected Home All
• Moved to Park 2
• Clicked Zero All to set the X and Y coordinates

For the Z-axis, I performed a probe test to accurately zero the height.

I first loaded and ran the G-code for the engraving process. After engraving was complete, I switched the bit and then loaded the G-code for the edge cut.

Here is the final result of my first PCB design:
