One is a mount for the proximity sensor. The other includes a place to insert a section of 12 mm wide LED strip to add a light to your print head. -The new firmware sets the printer's baud rate to 115200, so you'll need to make sure your control software matches. -Select the correct firmware to upload based on which extruder drive wheels you have. See the firmware notes for details. -The proximity sensor replaces the Z axis optical end stop and is wired to the same location on your printer's control board. Note that the proximity sensor requires 12V, but some older Felix control boards only supply 5V to the Z axis sensor. In that case, you'll need to wire the positive lead of the sensor (yellow wire) to the 12V power rail. See the upgrade guide for more details. -The printable bracket is attached by removing the front fan shroud bolts closest to the extruders, inserting the bracket ligning up the bolt holes in the bracket with the bolt holes in the fan shrouds, and reinserting the bolts . -With the printer nozzles just touching the build plate, the proximity sensor should be mounted with a 1 to 2 mm gap between the build plate and the sensor's tip. If you've already upgraded your printer to the new style print bed with the leveling adjusters above the build plate, follow the upgrade guide instructions for setting the proximity sensor gap as the sensor will need to clear those adjusters.
