• CNC Update
  
  
  
  • Working on greater accuracy
  
  
  • Most cuts are within 0.005 but certain situations can make it up to 0.01
  
  
  • Got a O flute bit in.
  
  
  • Feeds and speeds
  
  
  
  


• Analog tricks

Rapid Fire Opinion

• Arrow Electronics launches European FPGA Developer Contest 2020
  
  
  
  • Entry via the Arrow European FPGA Developer Contest 2020 web page and choose from the following Intel FPGA development boards: MAX1000, CYC1000 or AnalogMAX /DAQ1/2/3
  
  
  • Projects can involve anything from software, special IPs/interfaces and soft cores, to board modifications, adapter creation, adding a PMOD/Arduino, creating an IoT device, and programming algorithms for AI/CNN
