Week 6 PCB Milling

✅ group assignment: - characterize the design rules for your in-house PCB production process - submit a PCB design to a board house

Marcello helping with the group project.

Carvera is a fully automated CNC mill with advanced features like automatic tool changes and auto-leveling, making it an impressive piece of equipment. We tested its design capabilities.

✅ individual assignment: - make and test a microcontroller development board that you designed - extra credit: make it with another process

After having the PCB file, output the PCB as a Gerber file

These are the options to select for the options for the gerber file, for beginer stick to the basics

Look for Gerber to Image https://quentinbolsee.pages.cba.mit.edu/gerber2img/

Upload your file to the Gerber to image website and save output PNGs

Next step go to https://modsproject.org/ to make the CNC tool path

Select open program

Select Mill PCB and hit calculate you will have a NC file ready to feed to routers

This is a failed attempt because the layer height was not set very well, some parts of the PCB did not get cut very well

This is another attempt to get a PWM signal pin out from a rp2040 board, it is almost good, but a few of the tracies might be too thin, I did some tiny soldering of the parts to make sure it is connected well, saves time, and it works.
