MEP EP#213: My CNC Will Melt In Your Mouth

Parker

• Going to be doing Webinars for MacroFab.
  • How MFs tools make you a better electrical engineer and supply chain manager
• Learning AutoDesk Fusion360
  • Getting pretty good
    • Learning from Youtube and Stephen
    • Can be almost as fast and proficient as Parker was in Sketchup
• Braze it 420
  • Learning to braze brass radiators and steel gas tanks
  • Make sure there is no gas fumes!

Stephen

• CNC
  • Trying to buck the standard
  • Jointer/Planer -> table -> electrical work -> table saw -> torsion box -> gantry restoration -> new spindle
  • New 220V for the following
    • Welding
    • Brewing
    • CNC machine
• Fermentation controller
  • Audibles on some design characteristics
  • Switches/encoders
  • Probably going to go with wiring instead of all PCB mount
  • Footprints for Solid State Relays

Rapid Fire Opinion

• Raspberry pi 4 release fixes the USB problem
  • This is being treated as a “design for manufacturability” change
  • Lumped along with some silkscreen changes to avoid solder bridging and the SD card voltage switch moving
  • Why not fully announce this?
• Chinese Tariff Exemption for 2- and 4-layer PCBs
  • Valid until Aug. 7, 2020
• Fisher & Paykel PCB Silkscreen Design
  • The sad faces are where the hand insert components go
  • If any sad faces are showing, the operator hasn't finished their job.
