Reading Entries
  • Name: an abbreviation for what the pin does. This is for identification only.
  • Pin #: order of the pin in the connector.
  • Color: optional color-coding for the wire insulation.
    • Colors are solely to help visual identification.
    • Colors do not always match the wire colors that usually tail a component; this is meant to maintain internal consistency.

See the tips page for details.

This is a more complicated example of an enclosed Ender 5. It has the following differences from the previous example:

  • Direct drive (MOTE is in the toolhead bundle)
  • BLTouch (ABL)
  • 3-pin RGB toolhead lights (RGBH)
  • Enclosure thermistor (TC)
  • 2-pin enclosure fans (FC1, FC2)
  • 2-pin enclosure LED lights (LGTC)

Chamber

Although only six (6) pins are used, we here we use an eight (8) position connector to avoid confusion with the Motion #1 (X axis) connector.
