This is a replacement of the Backplate of the Voron 2.4 R2 skirts for a 350mm build. It has integrated MicroFit 3 connectors to have a clean connection to the outside world.

I am driving the ERCF not via a separate board, but via the Octopus Pro directly (using two motor drivers and the end stop/servo connection on the board).

You can fit in two 4pin MicroFit connectors for the gearbox and selector motor of the ERCF and a 5pin connector for the end stop and encoder sensor of the ERCF.

Additionally there is a separate 5pin connector for the exhaust fan and (to be on the safe side) a connection to an external smart filament sensor (3 pins).

Obviously you need on top of this STL the matching MicroFit Connectors. For the connector inserts you have to cut clean the clips. The connectors are held in place by a M3 screw (8mm) each.

Happy printing!
