Description
This is a remix of the CR-10/Ender 3 Direct Drivinator by Madau3D redesigned by Regularfry https://www.printables.com/model/68396-direct-drivinator-for-elegoo-neptune-2. I've changed the relevant dimensions and added cutouts so it fits the Elegoo Neptune 2S, which has a slightly different hot end alignment plate.
The Neptune 2S also has a filament sensor as stock, so this version also uses the plate attachment designed by Regularfry to screw the sensor to.
Print the mount at 45 degrees: see the attached .3mf for the orientation that worked best for me. There is a 40% and 50% infill .3mf that I have used.
Everything should be printed in PETG. In particular the legs of the filament-sensor-plate rely on PETG's flexibility to lock into place.
This mod follows the same philosophy of the original in needing no additional hardware, except for two things. The first is that I found you needed the cable extension that comes in the Microswiss CR10-Ender 3v2 upgrade and you mush reverse the pin sockets which is easy to do and no soldering. I've also designed a Cable holder unique to the Neptune 2s to be uploaded at a later date. You just need a couple of M-3 cap head screws. You attachment so the extruder cable didn't foul against the frame when the head was zeroed on the X axis. The attachment clip is included, but it needs a pair of M3 bolts to screw it down to the back of the filament-sensor-plate.
The second is that the extruder motor and the filament run-out sensor need their wires extending. These are straight-through connections that I used 3 in micro connectors that I got on amazon
Assembly should be obvious from the photos.
It's important that you put the stepper motor into the mount with the wiring socket facing upwards for the same reason. If you have it facing towards the back, the wires will rub against the frame.
I use sthe retraction setting in prusa slicer for the Ender S1. The E steps need a major adjustment also with the Flow Rate. Now It is printing beautiful prints. Good luke with this Remix for the Neptune 2S. These two videos by the Edge of Tech are extremely useful in tuning the new direct drive. Give him a follow and a thumbs up for this great content.
