  • 1. A mounting hole in the middle of one edge to allow for easier bed leveling thanks to Nophead for this suggestion.
  • 2. Larger LED and Resistor pads to allow for 1206 size surface mount components.
  • 3. Much larger area to solder the current carrying wire, easily connect ribbon cable (such as with the Mendel90 headbed connection). Also the through holes increased in size.
  • 4. The redundant pads on the non-heating element side of the board removed to prevent confusion.
  • 5.These are not electrically connected if the board is not plated (plated boards are bad for the reasons outlined by Josef Prusa above).
