Parker

• Python PDF
  • Looked at peoples suggestions and none really did what I needed
  • FPDF will do for now since I have made a template already
  • Most suggestions are building HTML then converting to PDF which is fine but not really a good solution
• Zebra Printers
  • ZPL or Zebra Programming Language
    • ZT230
    • ZD420
  • My process so far for making a ZPL webapp thingy
    • Zebra Designer 3 for Developers
      • Makes the Template
      • Push Template over to printer
      • Use Variables for fields you want to “input”
    • Zebra Setup Utilities
      • Allows talking to the printer easily
    • Zebra Browser Print SDK
      • Makes a USB bridge to a local web server
    • Web Server for Chrome

• CNC is fully functional!
  
  • Calibrated the three axis
    • Ran cable “tubes”
    • Set up spindle control
    • Table surfacing
      • 4 flute
      • 2&1/32 in diameter surfacing bit
      • 12,000 RPM
      • 100ipm
      • 0.005-0.01 DOC
• VFD EMC
  • Pages 10-12
  • VFD cables are to have the shield (screen) connected at both ends
  • This is an impedance thing
  • Shield should be at least 80% coverage
  • Foil and braid is best but most expensive typically
