my log of changes to be released with latest CAD model for SCUTTLE

Updates from V2.3 to V2.4 (not yet released)

  • wheel bracket RH with properly oriented scuttle logo
  • wheel brackets M3 holes increased to 3.3mm diameter for improved thread clearance and flush fit
  • battery pack - add compliant fitment for Anderson connectors
  • encoders - add labels to pins
  • encoder bracket - increase clearance so encoder board always fits between datum bumps
  • battery bracket thin wall increased (1.1mm to 1.5) for strength

Updates from V2.2 to V2.3 (released 2020.11)

  • Change CPU to Raspberry Pi (beaglebone is still compatible)
